To all whom it may concern:
Be it known that I, JOHN ,'B.,H AJJ'AWAY,
. of Brockton, in the county of Plymouth and is a specification.
-State'of l\Iassachusetts,-have invented a new and useful Stitch Separating and lndenting Machine, of which the following, taken in connection with the accompanying drawings,
My invention relates to a stitch separating and indentingiiiachine; .and it consists in certain novel features of construction, arrangeinent, and combination of parts, which will be readily understood byreference to the deseription of theaccoinpanying drawings, and to the claims hereto appended, and in which my invention is clearly pointed out.
In the manufacturing of boots and shoes of that class in which the outer soles are sea cured thereto by sewing through said sole and a welt secured to the upper and inner Sole it has been customary after the sole has been sewed to the welt to perform the operation called in the.trade-"pricking np the stitches, which consists in pressinga sharpedged tool between each two contiguous stitches on the upper side of the welt from the forward end of the shank on one side around the forepart to the same point on the other side to clearly define the division between the stitches and thus improve the a15- pearance of the boot or shoe.
The object of my inventionis'the production of a machine that will accurately separate or prick up the stitches regardless of slight variations in their lengths, the separating or. pricking-up tool being antoni atically adjusted to the division between two stitches before being depressed, said automatic adjustment being effected by the stitch itself. To accomplish this, I have'produced thema- .chinc illustrated in the accompanying drawings, in whieh- V Figure 1 is a plan. Fig. 2 is a front elevation. Fig.3 is a side elevation with a portion of the hand-wheel broken away. Fig. 4. is a-sectional elevation, the cutting-plane being on line arm on Fig. land looking toward the left of said figure. Fig. 5 is a side elevationof portions of the revolving work-support, the fixed welt-bearing work-support, the separating-tool and its carrying-lever, with,
the shoe shown in position. Fig: 6 is a front plan and an respectively elevation fof the same parts.

Figs. 15 and lG'are similar views of a modification oft-he gage and its support'made in piece. Figs. 17 and 18 are a front elevation and a longitudinal section of a modification of the revoluble work-support. Fig. 19 is an elevation of the ratchet-plate, looking toward the left of Fig. 4- Figs. 20 and 21larc respectively a plan and a front elevation of the h0rizontally-' reciprocating slide which" carries the rock ing separator-leverand the trip-lever. Fig. 22 is a plan view-of a portion of a shoe-sole and welt united by a line of stitches and showing a portion of'its length as it appears after the stitches have been acted upon by my machine. Fig. 23 is a detail plan view of feedlever.
In the drawings, A is the bed of the machine, provided with the legs A A", which may be formed integral with or besecu'red to said bed in anysuitable manner and by which the machine may be secured in the desired position upon'a bench or table. (Not shown.)
The bed A has formed upon or secured to its upper side the upwardlyproj eetin g stands A A in suitable hearings, in whichis mounted the driving-shaft B, havingmounted upon one end the hand-wheel G, upon its other end the grooved driving-wheel D, and between its two bearings the face-cams E and F and the combined cylinder and face-cam G 11.
The bed A has -formed in one piece therewith the upwardly-projecting blocks A and A, connected at their upper ends'by the plate A, and also the upwardly-projecting stand A, having the forwardly-projeating angular portion A, also connected to the plateA. In the front face of the block A is formed a :elevation of a revoluble' gage T-shaped vertical groove, to which is fitted,
so as to be. movable vertically therein the bar I, provided with the outwardlypro ectlng lugIQi-pto which is screwed the pendent rod .1, which passes through the threaded sleeve J, adj ustably set in the car A, formed upon or secured to the bed A, as shown .in Figs. 3

The plate A has formed therein a horizonan T-shapedgroove extending parallel to the passage of the .axis of the shaft B and has fitted therein, so
as to be movable endwi se thereof, the plate '0, having formed in its upper side the rectangnlar groove in, extending transversely thereof, and also having formed integraltherewith the ears 0' and O ,as shown in Figs. 20 and 21. The ear 0' haspivoted thereto the lever -P, one ann, k, of which extends in a nearlyhorizontal direction to the right of its pivotal connection to said ear, and the other arm, k,
of which extends upward, then to the left, andthen downward in the form of a goose, neck and is provided with the upwardly-projectin g lug Z and the laterally-projecting lug l, I.'/ is the trip-lever, pivoted to the ear-or stand 0 and provided nut m, the end of said set-screwbeing arranged to act upon the end of .the arm It of the-lever P to depress said arm by the action of the face-cam II, formed on the right-hand .end of the cylinder-cam G, as viewed in Fig. 1, upon. the truck or roll on, mounted upon a at its front end with, the set-screw m, adjustably set therein and secured in its adjusted position bythe checkstud set in the end of I the rearwardly-projecting arm-of said lever, said truck being-held in contact with said cam by the tension of the spring m, as shown in Fig. 3.
The lug l of the lever P has s uspendcd therefrom the rod a, to the lower end of which is connected one end of the spring or, the other end of which is connected to some fixed portidn of the machine and serves to move the arm k of the lever B downward, the tension" of said spring being regulated by the thumbnut 71?.

The pawl h is pressed into'contact with the ratchet-plate by the spring '1; in a wellknown manner.
The operation of my invention is asfollows:
'lhcseveral parts of the machine being in the positions shownin the drawings the operator.
first turnsth'e hand-wheel in the direction in-' dicated bythe arrow on Fig. 3 adistance equal: to'abont one hundred and twenty degrees; I when the separator-tool will have been raised to its extreme height and moved to ,the ex treme of its movement toward the right from the position in which it is shown in .Figs; 1
' and 2, the front endof the pressure-lever S The lug I has piv-.
- presses the lower work-supportL I the right of Fig. 1 and bears. upon a roll .9 mounted upon a stud set in .ciprocation,
to t l e proper point to impart ment of the plate will have been raised so as to permit the toolstock tobe raised by the action of the front end of the trip-lever P upon the end of the i arm is of the lever P, and the pawl end of the locking-lever will have descended,causing the shoulder i of thcpawl or .pawls (as preferably a-plurality of pawls h, having slightly varying lengths, are carried by said lockinglever) to come in contact with the pin 1', and thus be thrown out of cngagcment with the teeth of the ratchet-plate h. The operator now places his foot upon the treadle and dcagainst the tension of the spring (I to a suflicient dis-.
tance to permit the insertionof the sole edge between said lower work-support and the table N. He then takes the shoe in' his left hand with the heel toward the left and places the tread-surface of the sole upon the lower work support at a point at the forward part of the shank with the upper surface or the welt and with the edge of the sole restingiagainst been adjusted to a position to bring thestitch to be operated upon directly beneath the bul ge j on the lower end when the cam-shaft is set in motion. The first effect produced by the revolution ofthe shaft B is to-raise'the front end of the triplever P', and thus' release the rocking lever P and permit the tension of the spring a to move the arm k of the lever P and the toolstock downward and causetheend of the scpa beneath the ,upper work support ort'able N 9 the gage lipv or wheel which has previously f of the separating-tool j rator-tool j to press. lightly upon the stitch near the'middle of its length.
