This invention relates to machines for attaching buckles and other similar ornaments to the front or vamp portions of shoes and while primarily designed for this pur- 5 pose it may also be used for various other kinds of work.

In the shoe manufacturing industry, it

has been and now is customary in some styles of shoes, especially Oxfords, pumps and the like, to improve the appearance of the shoes by attaching buckles, rosettes or other forms of ornaments to the front or vamp ortions of the shoes. This work is necessarily done after the shoes are finished and heretofore has always been done .b hand which has involved a comparative y large expense in view of the character of the operation and much waste of time.

The main object of my invention is the provision of a machine for rapidly and efli-' ciently attaching buckles or other ornaments to shoes in a practically finished condition. To this end, my invention contemplates a machine having a work-supporting member adapted for supporting a sh'oein such posi-.

struction permits a finished shoe to be mounted on the end of the arm in a'sub stantially horizontal position, the end of the arm projecting into the forepart of the shoe and supporting the vamp portion thereof, the heel of the shoe being raised upwardly behind the inclined main portion of the arm. The operating instrnmentalities for attaching the ornament to the shoe may be mounted on an overhanging arm in position to operate upon the shoe and in the form of the invention herein shown comprises means for stitching the ornament to the shoe by what is commonly termed zigzag stitching.

Another object of the invention is the provision of means for automatically stopping the machine at the conclusion of a predetermined sequence of operations so that after the machine is started for attaching an ornament to a shoe, it will at the conclusion of the attaching operation automatically stop.

a In attaining this object of the invention, I provide means set in motion by the starting of the machine for rocking t e needle bar laterally to lay a pre-determinednumber of stitches and for throwingmut the clutch to stop the machine upon the conclusion of the pre-determined number of stitches. These means are so arranged that temporary pressure on a treadle will start the machine in operation after which it continues operating t rough the cycle and then automatically stops. By holding the foot treadle the machine may be operated continuously but in work of this character it is of advantage to secure automatic stopping at the conclusion of each attaching operation.

A further object of the invention is the provision of means for operating from the mainshaft of the machine such cooperating instrumentalities as may be mounted in the end of the lower or work supporting arm.

To this end, may be mounted within the Work supporting arm means for transmitting movement from the main shaft of'the machine to the instrumentalities in the end of the lower arm.

Other ob'ects of the invention will be more speci cally set forth and described hereinafter.

In the accompanyin drawings illustrating one embodiment o my invention, Figure 1 is a side elevation of a machine constructed and adapted to be operated in accordance with the invention; Fig. 2 is a plan view of the same; Fig. 3 is a longitudinal vertical sectional view of the machine; Fig. 4 is avertical cross-sectional view on line H in Fig. 2; Fig. 5 is a sectional view looking from right to left in Fig. 1, showing the two clutch members arc clutch mechanism in elevation with the clutch thrown in; Fig. is a similar view of the idler pulley wheel and expansion ring with the clutch thrown out; Fig. 7 is a front end elevation of the machine looking from right to left in Fig. 1; Fig. 8 is a rear end elevation looking from left to right in Fig.1; Fig. 9 1s a diagrammatic view of the cam for rocking the needle bar illustrating its 10 is a diagrammatic view of the stitching laid by the needle for one full revolution of said cam; and Fig. 11 is a central vertical sectional view of the clutch mechanism with the clutch pin out.

Referring to the embodiment of my invention, the frame of the machine comprises a hollow column or standard carrying a workup-por ng member preferably in the form of a down- .wardl inclined hollow arm 16 having its end portion 18 turned horizontally and an overhanging hollow arm 20 adapted for supporting operating instrumentalities (Fig. l The frame is preferably made in one cast ing, the head of the column being turned over laterally to form the overhanging arm and the work supporting arm projecting downwardly from the junction of the column and upper arm, the ends of the two arms being arranged in co-operative relation. My invention is not to be limited, however, to the specific form of frame shown since it may be made in any suitable form so long as the work-supporting member is of sufliciently small diameter to project into the:

forepart of the shoe and is surrounded by a clear and unobstructed space permitting a shoe to be mounted on the end thereof with its heel portion raised, to present its vamp portion in proper position to be operated upon. i

For fastening the machine to a suitable 22 the base portion of the column 14 may be provided with ears 2a bored to receive screws or bolts. On one side the column is provided with a rectangular opening to give access to the intable or support terior of the frame, which opening may be normally closed by a cover 25 having a finger-piece 26 to facilitate handling.

. Although various forms of instrumentalities may be mounted on the end of, the overhanging arm for performing different operations on finished shoes yet for attaching ornaments to shoes the machine is shown equipped with means for sewing the ornaments to the shoes by what is commonly termed zigzag stitching. The end of'the arm 20 is in the form of an enlarged open housing 28 having internally projecting pins 29 and 30 set in its top and bottom walls respectively which serve as bearings for the ends 81 of a vertical yoke 32 adapted for a lateral swinging movement on said pins. The pin 30 is made adjustable by being threaded through the top wall of the housing 28 and is held in adjusted position by a set nut 33. The main portion of the yoke lies operation; Fig.

drawings illustrating one outside the open housing 28' and is bored vertically to receive a needle-bar 34 adapted for carrying a needle 35 in its lower end.

For reciprocating the needle-bar 34, a portion 36' of the yoke housing is ofiset to expose a part of. that bar to permit it to be connected to the mainshaft 38 of the machine which is rotatably mounted in the overhanging arm in bearings 40 and 41 formed in the front end of said arm and rear wall of the column and in an intermediate bearing 42 carriedhy aweb 43 (Fig. 3). Fixed on the front end of the main shaft is a crank-disk l5 carrying'a pin 416 eccentrically positioned thereon, pin being connected to said bar by two links 4&7 and i8 pivotally connected together at 4:9 the linlr e8 being pivotally connected at its other end to a collar secured to the needle bar. The rotation of the main shaft and crank-disk through the medium of the two links imparts a reciprocatory. movement to the needle-bar.

In order to lay stitches from one side to the other or in a zigzag fashion, means are provided for oscillating the needle-bar housing laterally on the pins 29 and 30 as pivots. The upper end 31 has a lateral extension or arm which isconnectedby a link 56 to a pin 57 carried by a plate 58 pivotally mounted at one end on a pin 59 set in the top of the overhanging arm 20. The plate 58 swings laterally'on the pin 59 as a pivot to oscillate the needle-bar housing and to vary the extent of said oscillation the pin 57 is set in a curved groove 60 in the top face of the plate, the radius of said curve being the link 56. The pin 57 is dovetailed in the groove, the sides of which are undercut, and is held 62 which when tightened causes a binding actionbetween the base of the pin and the undercut sides ofv the groove. By moving the pin in the groove the eifectlve throw of the link 56 may be varied.

The oscillation of the plate 58 is controlled by a horizontal circular cam 65 having a cam-path 66 in its upper face to receive a roll 67 fastened to the under face of the plate 58 (Figs. 3 and 4). The cam is fixed to a vertical cam-shaft 7O rotatably mounted in a portion 71 of the overhangin arm (Fig. 4) and adapted to be rotated y the main shaft through the instrumentality of a worm 73 on the main shaft which meshesin adjusted position thereinby a nut I shaft for each revolution of the cam may be regulated by varying the pitch of the worm 73 and the teeth of the worm gear 74 but in the form shown, the cam is designed for one revolution for each ten revolutions. of the main shaft thereby laying ten stitches" on each revolution of the cam. The needlebar makes one complete up and down reciprocating movement for each revolution of the main shaft. In Figure 9 the cam path is shown laid out diagrammatically for accomplishing the ten lateral oscillating move- I ments of the needle-bar yoke housing necessary for the laying of the ten stitches on each compllete revolution of the cam.

to a hook shaft 82 rotatably mounted in the end 18 of the work supportin arm, the hook being held in lace thereon y a washer 83. The hook s aft is rotated from the main shaft through the instrumentality of a transmission shaft 85 supported in an inclined position in suitable. bearings 86 and 87 the bearing 86 being supported by a web portion of the frame and the bearing 87 being in the form of a bushing which is held in a web portion 88 of the lower arm by a set nut 89. U nthe inner end of the hook shaft is a evelled gear 90 meshin with a bevelled gear 91 on the lower end 0 the transmission shaft and on the upper end of the latter is fixed a bevelled gear 92 meshing with a suitable gear 93 mounted on the main shaft 38, all of these gears being keyed to their respective shaft in any suitable manner.

Any suitable form of clutch may be employed for transmitting movement from a source of power to the main shaft of the machine and'one form is shown comprising a hollow idler pulley wheel open on its inner face and a member 101 fixed to the main shaft. The end of the main shaft is supported by a curved bracket 102 secured at its lower end to the rear end of the frame of the machine by screws 103, the members of the clutch being mounted on said main shaft between said bracket and the bearing 41. The two members of the clutch are locked together for rotating the main shaft by means of a frictional expansion ring 105 carried by a pin 106 set in the fixed member 101, and an expanding member 107. The expansion ring 105 lies within the hollow pulley and is supported at its top on the pin 106 and is split at its lower end, each of said ends being provided with an upwardly extending curved lug or ear 109 between which is located the expansion member 107. This latter member is loosely mounted between 1 v the ears 109 and is elliptical in cross section lay and is normall with its long axis normally vertical as'shown in Fig. 6 but when turned sideways to the position shown in Fig. 5 it engages and presses the two cars 109 apart and expands the ring 105 to frictionally engage the inner surface of the Periphery of the pulley wheel 100 ,to lock the two members of the clutch together to turn the main shaft. 7

For turnin the expansion member it is provided on its top with an upwardly extending ear 110 adapted to be engaged by a similarly formed can 111 on a locking lever 112 provided with an integral lateral in 114 loosely mounted in the clutch mem r 101 and extending therethrough and having fixed on its reduced end a U-shaped arm 115. The locking lever-lies within the hollow pulheld in a locking posi-. tion by a spring to the free end of the locking lever 112 and at its upper end to a pin 118 set in the clutch member 101. The spring is under tension at all times so that its tendency is always to pull upwardly the locking lever and to 'throw the expansion member sideways. The

U-shaped arm 115 which is integral with -the locking lever lies on the opposite side of the clutch member 101 and serves as means for operating the locking lever a ainst the tension-of spring 117 to release t e expansion member and to disconnect the two clutch members. a a

For controlling the clutch, a clutch pin 120 is loosel mounted in a bearing 121 formed on t e machine frame and when thrown upwardly engages a radial shoulder 122 formed on the clutch member 101 by cutting it away in one side (Fig. 5) on the line 123. To reenforce the shoulder 122 to withstand impact with the clutch pin, the.

clutch member 101 is rovided with a thickened area 125 extending from the hub outwardly on a curve in drder not to interfere with the movement of the -U-shaped arm 115 secured at its lower end releases the arm 115 and the spring 117 I thereupon draws up the locking lever into the position shown in Fig. 5 and turns the expansion member to expand the ring 105 to make a frictional contact between the two members of the clutch; that is,. the pulley and the fixed member 101. The raising of the locking lever throws the arm 115 downwardly so that its end projects beyond the of the clutch these is ot'ovided shoulder 122. When the clutch pin is forced in again the cut-away portion of the fixed member on line 123 permits the pin to enter into stopping position and as the clutch re= volves, the end of the arm first engages the clutch pin and stops. The continued revolution of the clutch while the arm 115 stands still causes the lochng lever 112 to he turned downwardly against the tension of the spring 117 to release the expansion member and to disconnect the two members of the clutch so that when the shoulder 122' on the member 101 engages the clutch pin it stops the mm sheit and the machine. To prevent any rebound oi the member 191 on its impact on the clutch pin on upwardly extending mm is pivotelly mounted on s screw 131 in the items in position to engage shoulder 132 out into the edge of the monster till. A. spring 132% held one end by a screw 1% lies-ts the other end'egoinst the 136 to press inwardly for engagewith seid shoulder and to throw said arm outwardly when the clutch-pin pulled out, roll 13% carried by the engages toe lever in such position hat downward movement of the clutch oio pushes the arm out oi engagement wit" the said To pretest the entti. ye of oi" other foreign matter to the int-etior oi the clutch e covet piste 138 i fastened to inue'f face off the fixed meu" 81 1G1.

The spring 14% is connected atits of theclutch-pin end at its lowerv end to a pin 149 set in the frameot the machine, the

spring being under mnsion at all times. 'lhe hell-crank lever 146 is pivotally mounted on e stud 152 fixed in thecolumn ot the frame and one arm thereof bears against the lower end of the clutch pin and the other arm is pivotelly connected by a screw 154; to a rod' 155 which at its other end is pivotally connected to a. bell-crank lever 15? rotatebly mounted on a. screw pin 158 threaded in the end, of the overhanging arm and below the cam 65. The other arm of the bell-crank lever 15? has rotatably mounted thereon a sleeve 1'69 carrying an integral arm 161 extending upwardly in an oblique direction to engage at block 163 fixed to the under side of the com. The sleeve also carries a horizontal arm 165 extending outwardly and adopted to be connected to to loot tieedlc (not shown).

=FOT? oldingthe buckle or other ornament he atoched to the shoe when the machine is used for that purpose a. holding device of the general form of construction and operation disclosed in United States Letters Fatent No. 1,529,286 issued to meMerch 10, 1925 for buckle holding etechment may be em- (1 'ployed. This device is designated generally by the numeral 170 and since it forms no part of the present invention a description of it is not necessary. The said patent may be referred to for a complete description of its construction and mode of operation.

The buckle holding device 170 is fastened to the lower end of a vertical presser-bar loosely mounted in theopen' housing 28 and on one side thereof. For raising and lowering the presser-bar to removed from or placed on the work-support a cm 172 in the form of a quadrant is provided for engaging a roll 173 carried by a' screw 174 threaded into the presserbar. The cam has a cornerwise lateral pin 175 on which is fixed a rocking lever 176 for turning the cam. A helical spring 180- on the premer-bar abutting at its upper end a hollow screw 181 threaded through the. top wall of the housing 28 and at its lower end a collar 182 formed on the resser-bar, is under compression and holds the presserbar in a downward position with the roll 17 3 in engagement with the cam. Thepresserbar is therefore raised by the operation of the cam and when the latter is turned in the opposite direction the spring forces the Presser-bar downwardlyto. follow the cam. To permit operation by 'a foot-treadle the two ends of the rocking lever 176 may be connected 0 cords or

chains

185 and 186 to the two en respectively of a treadle 184 pivoted midway v rocking of the treadle by the operator raises and lowers the Presser-bar. The pressure of the spring on the Presser-bar may be regulated by turnin the hollow screw 181'with a wrench or simi ar instrument and for this purpose it is provided with a squared head.

In the use of the machine a shoe 190 is placed on the work-supporting arm in the position shown by broken lines in Fig. 3 in which the end of the armprojects into the fontepart of the shoe and su ports its vamp at e nament is to be attached. To secure this position of a finished shoe it is essential that the heel portion of the shoe be raised and the inclination of the main portion of the arm allows this to be done. After the shoe is properly positioned on the end of the work supporting member, the operator inserts-the buckle or other ornament in the holding device and lowers the resser-bar by manipulation of the treadle thereby clamping the shoe and locating the buckle thereon. The starting of the machine is effected by another treadle and the needle then lays the predetermined number of stitches in zigzag fashion over the center or other suitable portion of the buckle to secureit to the forepart of the shoe. 7 In the machine herein 10 and the machine then stops. The thread permit work to be' ,needle-bar housing is designed to la on a support 187. The

point where the hue e or other or-v It will be observed that the work of attaching buckles or other ornaments to shoes is very easily and expeditiously accomplished with the use of my machine and alarge saving in time and labor over the present day methods is accomplished.

Although the cam 65 for oscillating the I ten stitches in one complete revolution, as s own in Fig. 9 where the respective stitches are numbered, the intervening portions of the cam path covering the upward movement of the needle, it is apparent that the cam "may be designed for a greater or a lesser number of stitches.
