Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed June 13, 1901. Serial No. 64,345.

lowing description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. 1

This invention is an improvement on the pegging-machine represented in application for United States Patent, Serial No. 672,507

filed ori the 4th day of March, 1898. That application shows a peg-strip carrier or peg-- ribbon support operatively connected with the horn, stock-support, or work-support, whereby the position of the peg strip or ribbon with relation to thepeg-forming means is changed according to the varying thickness of the stock, so that there is formed a peg of a proper length to correspond with the stock being pegged. In that application the rmeans shown for connecting the stock-support andthe peg-strip carrier or support was so constructed that the horn and peg-strip carrier or support moved always substantially in unison.

In the machine herein shown the connecthe horn include a yieldingmedium in order that the horn may be given an eXtra depression when it is desired to remove or apply the work without Veffecting a corresponding movement of the strip carrier or sup ort. Preferably also stops are provided to'limit the movement of the peg-ribbon support in both directions.

Fig. 2 1s a left-hand side elevation of the lower part of the machine broken off from Fig. l, the column being broken out to show the parts within it. Fig. 3. is a detail of one form of yielding means in the connections between the horn or stock-support and the peg-ribbon support. Figs. 4 and 5 show much enlargedviews .of the nose and part of the peg-ribbon support and guide in front and in plan views, res ectively. Fig. 6 is a section-1n the line of ig. 5.V Fig. 7 is a section in the line ofv Fig. 4. Fig. 8 is a section in the line y of Fig. 6; and Fig. 9 is a detail showing one end of a iece of peg-ribbon, the lines of cut to form tfie peg being shown by full lines and the cut made in` removingy the surplus being indicated by a dotted line.

I have chosen for the sake of illustrating my invention in a practical working machine to embody it in a machine .of the type represented in United States -Patent, No. 490,624, January 24, 1893.

ANo. 490,624.

That a shortened peg may be cut from a I shown, a peg-strip guideway F, united by peg-ribbon, the peg varying in length aceordl screws or otherwise with a block F2 by an aning to the requirements of the stock being calipered between the foot-plate b4 and the upper end of the horn B, the following means have been provided.

I have mounted upon a stud k12 a lever hw, having at its upper end a roller-stud h, (shown by dotted lines, Fig. 1,) which is kept pressed by a spring g against the face of a cam g5, carried by the shaft C2, as in Patent No. 490,624. rlhe lower end of the lever hm actuates suitable mechanism, as provided for in my said application, to engage and move the peg-strip F, represented as coiled and suitably sustained on a plate 1", having a stud r2 entering a hole in an arm r3, iXed to the head A.

E2 indicates part of a driver-guide attached to the head B, as in United States Patent The guide has connected with it by a suitable screw 8 a nose E, having usual holes for the awl and driver. The driver-passage in the driver-guide is open at one side 10, as best represented in Figs. 6 and 8, to leave a space or mouth through which the peg-forming means pushes the formed peg into position under the driver, the peg being driven through the hole 12 in the nose and entering the stock resting on the horn.

As shown in Figs. 6 and 8, the guide E2 receives against it one end of a block E3, having an ear 13, which embraces a portion of the driver-guide E2. The block E3 is grooved, as illustrated in this present embodiment of my invention, to receive and guide the pegforming means and the surplus -ren1over. The peg-forming means presents two operating cutting edges, one designated 15X and the other 15W. The edge 15 occupies a vertical position and coperates with the vertical wall 8O of the throat 36 in the block E3, which communicates with the open side 10 of the driver-passage. The peg-shortening edge 15 is substantially horizontal and cooperates with the top or upper edge 35 or" the throat 36 and serves with the edge 15X to form at one operation a shortened peg, such as n, Fig. 9. The edges 15 and 15XX are represented as formed on one and the same blade 15.

The surplus-remover 14 has its edge 14 located somewhat behind the edge of the pegforming device, and it is shown as connected therewith in an adjustable manner by a bolt 16 in a slot 17. The edge oi' the surplus-remover meets the peg-strip at its side opposite that which contacts with the wall 37 orn the block E3 above the throat 36, cuts into the peg-strip, and removes any surplus wood, such as n', Fig. 9, left after the operation or' the peg-former. The line of the cut made by the surplus-remover is indicated by the dotted line n2 in Fig. 9.

The plate r has connected with it, as

gle-iron F3. (See Figs. 5 and 8.) 'lhe block F2 and guideway F constitute one suitable form of peg-strip carrier or support.

Viewing Figs. 6 and S, it will be seen that the end or' the peg strip or ribbon F occupies a position in the slot 3() of the block E when a peg is to be formed by the operation ol' the peg-forming means. The head of the peg will be formed at a distance from the upper edge of the strip equal to the distance between the upper edge of the strip and the upper horizontal shoulder 35 of the throat 36.

The blade 15 has a slot 1S, which is entered by a pin or projection 19, (sec dotted lines, Fig. 1,) carried by an arm 20, common to said application, mounted to turnlooscly on a stud 21, extended from the l'rame A, said arm 20 having a stud 22, (shown by dotted lines, Fig. 1,) which is embraced by a link 24, embracing a stud carried bythe movable head B, so that said head in its feeding movement may turn the arm 2() and actuate the peg-forming means and surplus-remover at the proper times a spring 68, common to said application, and having its coiled part embracing a stud-screw 68X, one end of said spring acting against said lever taking up lost motion in the peg-forming means.

The block E3 has a suitable groove, (sec Fig. 5,) which receives a projection m, extended Yfrom the part F2 oi: the peg-strip earricr or support. The part F2 receives a stud or other screw F4, which is embraced by a link m', loosely connected with the front end of a lever m2, pivoted at mi* on a stand m, erected on a fixed part of the head A. The rear end oi said lever m2 has jointed to it a rod m, (see Figs. 1, 2, and 3,) connected at its lower end with a block 60, surrounding loosely the rod d' The block 6() is engaged on its upper and lower sides by springs 61 and 62, which surround rod d, and are engaged at their opposite ends, respectively, by a nut 63 and a collar 64, the nut being adjustable to change the tension of the springs. These springs constitute one form of a yielding medium in the connections between the peg-strip carrier and the horn.

The parts thus far described, with the exception of the block 60, the springs 61 and 62, and the nut and collar 63 and 64, are common to my application bereinbefore referred to, and the present invention relates particularly to the yielding medium in the connections between the peg-strip carrier and the horn. One object of this yielding connection is to enable the peg-strip carrier to follow the horn in all changes of position occasioned by varying thickness of the stock, but prevent it from following the horn in theextreme movements of the horn, as when it is given an extra depression or when it rises to an unusual height. It is unnecessary and undesirable IOO IIO

for the peg-strip carrier to follow these ex-V treme variations in the position of the horn.

When the horn is given an extra depression for the removal or application of stock, a suitable stop 65, shown as a stud-screw extended from the projection m of the peg-strip carrier, (see full lines, Figs. 1 and 8, and dotted lines, Fig. 5,) meets the lower endof a slot 66, out in the block E3, and prevents further downward movement of the peg-strip carrier. Thereafter in the further downward movement of the horn the spring 62 will yield and no further movement will be imparted to rod m3X and through it to the peg-strip carrier.

When the stock is removed and the horn is released, the spring bsacts to lift the horn, and if the horn should rise to an unusual height, as in case no work were between it and the foot-plate', the stop 65 would meet the upper end of the slot 66 and limit the extent of upward movement of the strip-carrier. It will thus be observed that the movement of the peg-strip carrier is yieldingly eHected in both directions.

In the form in which I have herein chosen to illustrate my invention the peg-forming means and peg-shortener are shown as slidably mounted in aguideway of the block E3, extended laterallyv from the nose having the driver-passage, andthe supp ort for sustaining the peg-ribbon is placed in a slot between said block and nose and is made vertically movable in said slot for-a greater or less distance through .connections between one end of the lever m2, which is jointed to the pegribbon support, and to a rod connected with the horn-lever, which latter is connected with the horn-rod b3. When, therefore, the position of the horn is changed due to` variationsin thickness of the stock interposed between the top of the horn and the under side of the nose, the peg-ribbon support will be moved vertically more or less in said space, and more or less of the upper edge of the peg-ribbon will be put above the edge X according to the length desired for the shortened peg next to be cut and driven. The peg-ribbon support having been put automatically in its proper position for a peg of the desired length, due to change of position of the horn in calipering the stock, the cutters 15' and 14 will be moved toward the peg-ribbon, and blade 15 will cut out the shortened peg and force it through the throat 36 into the driver-passage of the nose, and during this operation the edge of blade 14 will meet the part of the peg-wood sustained by the face 37 above the shoulder and will cut off and remove from the pegribbon the surplus, (designated by n, Fig. 9.)

The springs 61 and 62 are strong enough to resist any material compression as the horn is moved in usual manner to caliper the stock in which the peg is to be driven; but said springs may yield topermit the horn to be' abnormally moved, as by or through pres- `sure of the -foot of the operator on the horntreadle C". y

It will of course be obvious that the advantage of the present invention would be equally well secured if the peg-forming means were movable and the peg-strip carrier stationary. The essential thing. is to have one of these parts movable with relation to the other and to have the movable part yieldingly connected with the mechanism which is arranged to measure the thickness of the stock, and that mechanism is, in the form vin which my invention is herein shown, the horn or stock-suport.

I-Iaving described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a machine ofA the class described, av

stationary foot-plate, a horn or stock-support, 'peg-forming means including a pegshortener, a peg-strip carrier, one of said two last-named parts being movable with 'relation to the other to vary the length of the peg, and means, including a yielding medium, for changing the position of said movable part according to variations in the thickness of the stock.

2. In a machine of the class described,fpeg forming means including a peg-shortener, a peg-strip carrier, one of said two last-named parts being movable with relation to the other, a movable horn or stock-support and connections, including' a yielding medium, between said horn or stock-support and said movable part.

3. In a machine of the class described, pegforming means, a peg-ribbon support, one of said parts being movable with relation to the other 'to vary the length of the peg formed from peg-ribbon sustained in said support, and means normally controlled by the thickness of the stock for varying the position of said movable part, said means including a yielding medium.

4. In a machine of the 'class described, a foot-plate, a peg-ribbon support, a cutter cooperating therewith to reduce for a portion of its length the width of a ribbon sustained in said supp ort, one of said parts being bodily removable with relation to the other, means to limit such movement, a stock-support movable toward and from the foot-plate, and an intermediate yielding connection between said stock-support and saidl movable part whereby slight movements of the stocksupport relatively to the foot-plate produce corresponding relative movements between the ribbon-support and the cutter, but whereby during a further movement of the stocksupport the relative position of the ribbonsupport and the cutter will not be changed.

5. In a machine of the class described, a foot-plate, a horn or stock-support, pegforming means including a peg-shortener, a peg-strip carrier, one of said two last-named IOO parts being movable with relation to the other, and mechanism for moving said movable part vertically according to variations in the thickness of the stock, said movement being yielding in both directions.

6. In a machineof the class described, peg forming means including a peg-shortener, a peg-strip carrier, one of said two last-named parts being movable with relation to the other, a horn or stock-support and yielding connections between said horn or stock-support and said movable part, wherethrough all movement of said part is yieldingly effected.
