" Be it known that-1, GEORGE E. RoLLIS, 0f

i East Bridgewater, county of Plymouth, State of Massachusetts, have invented an Improvement in Welt-Making Machines, of which the followingfdescript'iou, in connection with the -accompanylng drawings, 1s a specification,

`like letters on the drawings representing like parts. y

`My invention is a machine for quickly and accurately preparlng welt-strips for Goodyear ."Work and other nses'requiring welting.

` end, and a The lconstructional details and various advantages of my invention will be pointed out inthe following description, reference being had to the accompanying draw-ings," in which I have illustrated a preferred embodiment of vmy invention, which will be more particularly defined in the appended claims.

In the drawings', ligure 1 is a top plan view of one form ofc my invention. Fig. 2 shows thev same in front elevation. Figs. 3 to 5 are enlarged ./sectional details taken' on the lines 3 3, Fig. 1, 4 4, Fig. 5, and 5.5,'Fig. 4', respectively. Fig. 6 is a fragmentary detail and top plan of'a yportion of the welt cut by this machine; and' Fig. 7 is a transverse sectional view thereof on the dotted line '7 7, Fig..6. v

Mounted on any suitable base a and table a' is a drive-shaft of, journaled in a standard f as and provided with a rotary cutter a? at one drive-pulley a5 at the other end.-

djacent said shaft is a guidefpulleya about which thewelt-strip 'w may pass for accurate guidance, and nary cutters @T af adjacent thereto` are` prelimi- 1on,g,\'itudinal groove w' and an opposite bevfrom said cutter and angularlynpfand 'down eled edge rfon thestrip fw.

ment with the head of an adjusting-screw L12 groove w'., which an' leye orhole a 1n the end of said knife. The knife a is arranged at the Vproper angle required for thebevel wz. v Op,-

postte the rotarycutterafl r-provide a weltvguide el, capable of 'adjustment toward and'V for enabling the machine to va'ry'the. depth and length 'ofr thelftransverse the welt edge of the welt and also having a curved rib erated, respectively, by for cutting, respectively, a'

These-knives are y "nonnted'in a casting or other suitable holder a, as shown in detail in Figs. 4 and 5, the' knifeblade a7 beingnotched at a1 for engage,

the knifefl .made by the rotary cutter according to the v purpose for which the welt is rto'be used. rlhis holder comprises twolparts al a, the former having an upturned end slotted at @nl and a delecting portion consisting of a mem# ber a2, shown vas a rib or horizontal bead forl entering the groove fw' inlthe welt-strip, and

adjacent to said member'a pocket w21 to receive the lower edge of the welt-strip as it is turned back out of the way of the cutter end or knife al by the rib @20. A The part a extends rearwardly at (L22, 'where it is provided with an upturned end @23, engaged -by an acljusting-screw @2.4, working in the part-ct17 for adjusting the welt-receivingopening to-fit different thicknesses ofwelt. l The said ltwo parts are clamped together vertically by a bolt c25, the part auvpreferably having an overhanging enda26 forretaiI-iing the upper @'27, fitting into a 'corresponding groove in a carrier-block w28, mounted on a stationary support a, herein shown asa part of the same casting which provides the standard tra. The carrier w25 has a depending endA as, en-I gaged by an adjusting-bolt@81 lfor adjusting the same out and, in, and thereby col're'spond- Y ingly adjusting the holder w15 `out and in. The: carrier w28 has an elongated slot a (shown in dotted lines, Fig. 3) for receivinga set-screw as from the holder for clamping .the latter at the angle of adjustment desired.`- Beyond the three cutterslprovide suitable feeding mechanism, herein shown :1s-comprising a'guide-j v lwheel '0:34 and opposite driving-wheelv d, op-

gears a3 w37', to latter of -which is` secured av ratchetl arthrop-v erated by a spring-controlled pawl'asf, whose y arm ai is engagedl lat proper intervals by a lug a on the shaft a2, therebyratcheting the feed-rolls forward after each cut, so as to bring the weltinproper position for-the next" Y Cub, ,i l Inv operation the 'welt-stripw as it is fed forward bythe feeding mechanism is cut hy ICO held the knivesy af a8 at the points w' @n2-and is taut between its bent portion'atvtheguide?` I' pulley at. 'and the feedwheels a w35 under even tension, so that as the continuallyrotat- Y ing cutter a* engages said strip ift is-"enabled '105s to make a clean cut exactly as required, 'the welt-strip being of the holder and sustained-by the bifurcatedA upturned end, so asto'prevent any lragged or i improper cut. As each vertical or transverse' 11o held firmly between the jaws ,-,Iff'

cutis made the welt iA fed 'fera rd one step through the unchangi assage 'fitting the same and formed betwe the jaws or parte a a" of the holder, the Wheel 1,35 being pro- 'vided with a piurality citi-projecting portions l l v e, which engage the vertical notches w" aiready cut 1n the Welt and' prevent the welt from slipping," The length cfcut w3 may be increased to any extent'desired simply by rocking the holder so as to cause the -cutter to-enter the leather higher up than shown, and the depth of the cut may bevaried by moving said holder towardthe cutter, While the Shape of the cut depends upon'whetlier the welt-strip is maintained fiat in its cut por tion or-is curved by the holder. By bending' the lower edge of the welt back, as shoivn,

not only is the leather brought under tension for enabling the cutter to operate to the best advantage, but the ntches w3 (or Whatever :form of cut or 'incision-the particular knife al used may make) are coniined to the upper portion of the Welt, `as shown in Fig. 6, whereas by not bending the Welt cut so far back said notches can be made to extend farther, iidesired.

It will be understood that my inventimi is not restricted to the constructional details shown, as many variations in form, arrange ment, and combination of parts may be resorted to Without departing from the spirit and scope of my invention. For instance, iti is obvious that by varying the shape or angle i of the knife al. the shape of the cut w3 will be varied; the essential feature being 4merely .that the transverse cuts. Whether simply incisions or otherwise, shall be accurately controlled as to depth and length, so as to' leave a smooth uncut outer edge and exposed sidei to the Welt. y y
