IT GUTTA PERCHA. Wharf Road, City Road, London. cannot now be doubted even by the most sceptical, but that GUTTA PERCHA must henceforward be regarded as one of the blessings of a graciousP rovidence, inasmuch as it affords a sure and certain protection from cold and damp feet, and thus tends to. protect the body from disease and premature death. Gutta Percha Soles keep the feet WARM IN COLD, AND DRY IN WET WEATHER. They are much more durable than leather and also cheaper. These soles may be steeped for MONTHS TOGETHER in cold water, and when taken out will be found as firm and dry as when first put in. Gutta Percha Tubing, Being so extraordinary a conductor of sound, is used as speaking tubes in mines, manufactories, hotels, warehouses, &c. This tubing may also be applied in Churches and Chapels, for the purpose of enabling deaf persons to listen to the sermon, &c. For conveying messages from one room to another, or from the mast-head to the deck of a vessel, it is invaluable. For greater distances the newlyinvented Electric - Telegraph Wire covered with Gutta Percha is strongly recommended. Mill Bands. The increasing demand for the Gutta Percha strapping for driving bands, lathe-straps, &c., fully justifies the strong recommendations they have everywhere received. Gutta Percha Pump Buckets, Clacks, &c. Few applications of Gutta Percha appear likely to be of such extensive use to manufacturers, engineers, &c., as the substitution of it for leather in pump buckets, valves, &c. These buckets can be had of any size or thickness WITHOUT SEAM or JOINT, and as cold water will never soften them, they seldom need any repair. Gutta Percha Picture Frames. The Gutta Percha Company having supplied HER MAJESTY THE QUEEN with several elaborate Gutta Percha Picture Frames for Buckingham Palace, which have been highly approved by the Royal Family, fully anticipate a great demand for frames from the nobility throughout the country. In order that the picture-frame makers may not be injured, the Company will supply the trade with the mouldings, corner and centre pieces, &c., and allow them to MAKE UP the frames. Pattern books for the trade are now ready.

Edited by J. C. Robertson, 166, Fleet-street. ALLPORT'S PATENT IMPROVEMENTS IN THE MANUFACTURE OF Mr. AllporT'S PATENT IMPROVEMENTS IN THE MANUFACTURE OF WEAVERS' MAILS. [Patent dated May 14, 1849. Specification enrolled November 14, 1849.] WE gave in our last the claims of Mr. Allport, and now proceed to extract from his specification the following details of his invention: "Weavers' Mails" are those small metallic substitutes for the treddle-eyes of the old plain weaving looms, which came into use along with the draw-loom and other figure-weaving looms of more recent date. As these mails are now made, the process consists of three principal operations :-First, a strip of malleable metal (copper, brass, or iron) is pierced at its extreme end with the number of holes suitable for a single mailsay three, four, or more—and these holes are produced by means of punches and corresponding beds fixed in and worked by a common fly-press, but only one set of holes is in this way pierced at a time, that is to say, by one stroke of the press. Second, the strip of metal, after it has been so pierced throughout, is passed between another set of tools, by which the mails, that is to say, small pieces of the metal, of an elongated oval (or any other required form), each embracing one of the sets of holes, is cut out and separated from the strip; but here, again, one mail only is cut out by each stroke of the press. And, Third, the detached pieces constituting each a mail in a rough state, are each separately subjected to what is technically called "a striking process," in order to bevel or round the outer rim of the mail, and also the edges of the inner holes. Plans of mails of different patterns, as thus completed, are given in fig. 1o. Now, Mr. Allport's improvements con.. sist, firstly, in piercing a number of sets of holes (instead of one set only) at one and the same time, or by one operation. Secondly, in cutting out a number of mails at one and the same time. Thirdly, in effecting by one operation both the piercing and cutting out of mails. Fourthly, in striking or bevelling the outer rims and interior holes of a number of mails (instead of those of one mail only) at one and the same time. And, fifthly (which is an improvement arising out of and consequent on the preceding improvements), in attaching the punches and beds to their holders, in such manner that on any of them breaking or wearing away, they can be replaced without having to cast the whole aside. The new tools by which these improvements are effected are thus described: Fig. 1 is a side elevation, fig. 2 a cross section, and fig. 3 a top plan of the tool which I employ to pierce a number of sets of holes by one and the same operation. A, is the holder, and a a eight sets of punches, three in each set, which are inserted in the holder all on one line. The number of sets, and also the number of punches in each set, may be varied as may be required. At their upper ends they are slightly burred, as shown in fig. 2, to prevent their starting while at work; and the holders are countersunk to receive these burrs, so that they may come flush with the top face of the holder, A. When any of these punches are broken or damaged, the holder, A, is detached from the bolster of the press or other machine used to work the tools, the faulty punch struck out, and a new one inserted in its place. Fig. 4 is a top plan, and fig. 5 a section of a bed adapted to the piercing tool just described. Fig. 6 is a side elevation; fig. 7, a cross section; and fig. 8 a top plan of the tool which I employ to cut out a number of mails at one and the same time. A is the holder, and aa the punches, which are burred at the upper ends like those of the tool first before described. Fig. 9 is a top plan, and fig. 10 a cross section of a bed adapted to the cutting-out tool last described. BB are two pins which project beyond the top surfaces of the two outermost of the row of piercing punches, fig. 6, and take into corresponding holes in the bed-plate, fig. 9, and thereby serve to keep the two tools in a perfect state of reciprocal adjustment while the strip of metal is passing through between them. Fig. 11 is a top plan; fig. 12, a side elevation; and fig. 13, an end view of the tool by which I both pierce and cut out mails at one operation. A is a holder, and Aa the punch-holder, which is slid into a recess in the upper face of the bed-piece, and bevelled at the sides to fit corresponding bevels in the sides of the recess (see fig. 13). H is a stop-piece, which is bolted to one end of the bed, A; P1 P2 are two rows of punches for piercing the mails; and C1 C2, two rows of punches for cutting them out-the piercing and cutting-out punches being placed in an alternating order. RR are seats raised on the face of the sliding holder, Aa, and cut out of the solid metal of Aa, into which the punches are inserted (from beneath), there being one seat for each set of mail holes, and one for each cutting-out punch. The punches are burred at their upper ends exactly as in the single tools before described, and are removed and replaced when required in the same way. Fig. 14 is a plan; fig. 15, a side elevation; and fig. 16 an end view of a set of beds adapted to the double tool last described. Al is a holder, which is slid dovetail-wise into a chase or carrier, A2, which again is slid, also dovetail-wise, into a recess made for it in the upper surface of the foundation bolster, A3. Pia and P2 are the beds corresponding to the piercing punches, P1 and Pa; and C1 C24 are the beds corresponding to the cutting-out punches, C1 and C2. The beds are inserted into the holders in pairs, that is to say, each of the circular pieces, cc, contains one of the beds, Pia or P2, and Fig. 20. one of the beds, Cia or C2a. The pieces, c, are raised a little above the general surface of the holder, and each bed is separated from the other down to the depth of the projecting part, by a cleft, d. Each of the pieces, c, is also conically enlarged to a slight extent towards the bottom, which prevents its starting out of its place when in work, but enables it to be easily removed and replaced when the holder, A1, is withdrawn from its chase and turned upside down. The piercing punches and cuttingout beds are so arranged in respect of one another, that the second sets of both shall come opposite the intervals between the first sets, whereby the amount of waste is greatly diminished, and room is obtained to give the requisite strength to all parts of the tools. Fig. 21. 000000000 Fig. 18. 00000000 000000000 000000002 0000000000 "releaser," which E is a plate called a has holes in it corresponding with the punches of fig. 12, and is secured by four bolts, 1, 2, 3, 4, to the under bolster when they are set to work, in order to prevent the strip of metal following the punches as they are withdrawn from the cutting out beds. The double sets of punches and beds last described, being fixed in a machine in the usual way, with the sides, FF, in front, the strip of metal is introduced endwise between the beds and the releaser, and two sets of holes successively pierced in it by two strokes of the machine. The strip is next moved forward on to the top of the first row of cutting out beds, Cla, and by a third stroke of the machine, the metal containing the first set of rows is cut out into as many mails as there are sets in that row. And so the work goes on continuously, a new row of holes, and a new series of mails being cut out by each stroke of the machine. A representation of a piece of metal in the waste state after it has gone through a series of these operations is given in figure 16". Fgs. 17 and 18 are plans of two sets of dies, D1, D2, by which I accomplish the "striking" or bevelling of a number of mails by one operation, and fig. 19, a cross section thereof on an enlarged scale. A A are the die holders. Each of the set, D1, is an exact counterpart of the obverse side of one of the mails, and each of the set, D2, Y 3 |
