Specification of Letters Patent.

Patented Feb. 27, 1912.

To all lwhom 'it may concern:

Be it known that I, STEPHEN SNOW, a citizen of the United States, residing at Everett, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain Improvements in Pounding- Up Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines adapted for use in the manufacture of boots and shoes for performing the operation known in the art as pounding-up the boot or shoe The pounding-up operation usually follows immediately after the lasting 'operation in which the marginal portion of the upper material is worked over the edge of the last and secured to the innersole by tacks or other temporary fastenings, as is well understood although it may be performed in connection with the lasting operation and shoes are sometimes subjected to similar treatment preparatory to the lasting operation. The upper material, when lasted over the edge of the last, frequently does not lie as close to the last and innersole as is desirable. This imperfect fitting of the upper is especially apparent at the toe and heel of the shoe where the upper material, which, at these portions of the shoe usually includes toe and heel stiffeners, is thicker and less pliable than at other portions of the shoe.

The marginal portion of upper material on the bottom of the last also has an irregular uneven surface, particularly at the toe and heel where the stock is plaited or gathered in laying it over the innersole, and frequently the tacks employed for securing the upper to the inner sole are not all driven a uniform distance into the work. The bottom of the shoe, therefore, presents at the end of the lasting'operation an unsatisfactory surface upon which to lay the outersole.

In the better made shoes it is the present 4 practice to even the bottom of the lasted slice for the reception of the outersole and to correct the above-mentioned'defects in the fitting of the upper to the last by pounding-up the shoe with a hammer held in the hand of a workman. In that manual operation the shoe is held upon a suitably shaped rest and subjected to hammering along t-he overdrawn edge of the upper on t-he last bot-tom. As thus carried out the pounding-up of boots and shoes is a slow and somewhat laborious operation, calling for a considerable skill and judgment on the part of the workman and in many cases it is imperfectly performed.

One object of the present invention is to provide a machine by which the pounding-up operation may be performed with rapidity and uniform work produced even by an unskilled workman, and an important feature of the invention consists in providing novel means by which the upper material may be forced downwardly toward the nnersole and at the same time drawn inwardly away from the edge of the innersole.

I have found that it is essential that the blows of a pounding-up machine be so rapid and of such force that it is impracticable for the workman to sustain the work in his hands because of the rapid succession of hard blows, and further because itis not possible for a workman to hold the shoe up to the machine .with sufiicient lirmness for the shoe to be properly operated upon.

One important feature of the invention, therefore, consists in the combination with mechanism for delivering rapid pounding-up blows to the work, of means for properly supporting the work in position to be operated upon. Preferably the machine will be provided with means for supporting the shoe in a substantially rigid manner and inv the embodiment of the invention herein shown means is provided for positioning the shoe in predetermined relation to the stroke of the pounding-up means.

With these ends in view the machine herein shown as embodying my invention `is provided with a shoe support movable for placing the work in positionv to be operated upon, and with a stop or abutment for determining the position to which the shoe may be moved. Preferably also means is Vprovided for automatically raising the work support to place the surface of the work, whatever may be the height or thickness of the stock, against the abutment and therefore in predetermined relation to the stroke -of t-he pounding-up means,

The machine is also provided with means for locking and rigidly sustaining the shoe support in the position to-which it is raised.

The abutment may be vertically adjustable for varying as desired the position to which the work shall be raised with relation t0 the lower limit of the stroke of the pounding means.'

Preferably and as herein shown the abutment is arranged to engage the face of the innersole at a distance inward from the edge of the last, instead of engaging the upper material which covers the marginal portion of the last bottom and of course presents an irregular and uneven surface not well adapted to coact with' the abutment in determining the position of the work.

Other features of the invention, including details of construction and combinations of parts, will be hereinafter described and pointed out in the claims.

Figure 1 is a side elevation, partly in section, of a machine embodying my invention, the shoe support being shown in position to sustain the heel ofthe shoe. Fig. 2 is a similar view of a portion of the machine showing the shoe support in position for sustaining the toe of the shoe. Figs. 3 and 4 are perspective views, partly in section, of the heel portion o-f a shoe, illustrating the effect of the pounding-up operation, Fig. 3 showing the shoe before being pounded-up and Fig. 4 showing the same shoe after being operated upon by the pounding-up machine.

The machine comprises a frame 2 provided with bearings for a driving shaft 4 having fast and loose pulleys 6 and 8. The shaft 4C is provided on its front end with a head carrying a crank pin 10 which has a ball and socket connection with a link 12. The link is guided through an opening in the frame, and at its upper end has a similar universal-joint connection with a sleeve 14 loosely mounted on the operating rod 16, which supports at its lower end the pounding-up device 20. The sleeve 14 is arranged between fixed collars 22, 24e on the rod 16, and a spring 23 is interposed between the lower collar 24 and said sleeve. By this arrangement the rod and the pounding-up device are reciprocated from the crank pin on the driving shaft, the upward stroke being positively effected, while the downward stroke or striking movement is yieldingly effected.

The rod carrying the pounding-up device 2O is arranged obliquely, as shown in Fig. l, being guided in forwardly and upwardly extending arms 26, 28 of the frame. The arm 26 sustains a swiveled bearing 3() mounted to turn on center pins 32, one of which is shown in Fig. 1. The portion of the rod 16 which extends through the lower arm 28 is provided with a slot 34 extending downwardly and forwardly, and a guide pin 36 secured in the arm Q8 extends through said slot. The pin and slot constitute guiding means for directing the pounding-up device forwardly as it descends into striking lcontact with the work, whereby said pounding-up device is caused to draw the upper materials over the edge of the last and innersole as said materials are flattened down on the innersole. The downwardly and forwardly directed blows of the pounding-up device thus force the upper inwardly over the innersole, thereby taking up any slack there may be and also preventing the upper material from bulging away from the side of the last as it would otherwise tend to do when iiattened down on the innersole by the pounding-up operation.

A rest 38 is adjust-ably mounted on the machine frame in position to be engaged by the side of the shoe for determining the distance the shoe may be moved under the pounding-up device Q0. The rest serves the further purpose of holding the upper material firmly in contact with the side of the last near the edge of the shoe as the workman presses the shoe against the rest, thereby assisting in shaping the edge of the shoe as the latter is acted upon by the poundingup device. By the term edge as applied to the shoe I mean to designate the edge or corner formed by the upper material lying against the side of the last and the upper material on the bottom of the innersole.

The height at which the shoe may be presented to the pounding-up device is determined by a stop or abutment 39 which is adjustably mounted in the lower arm 28 of the frame 2. The stop or abutment is so located relatively to the edge rest that it engages the bottom of the shoe some distance from the edge of the shoe, and therefore contacts with the even surface of the innersole instead of contacting with the irregularV surface of the upper material on the last bottom. rlhe abutment 39 will in practice preferably be adjusted longitudinally to position its lower end at the desired distance above the lower limit of the downward stroke of the pounding-up device 20 so that the pounding-up device, by striking the work more or less before the end of its normal stroke, will Vpound the work with greater or less force. The spring Q3 of course yields to permit the downward stroke of the pounding-up device to be arrested while the actuating link 12 and crank pin 10 continue to move. By adjustment of nut 24 to increase or diminish the tension of the spring 23 the force with which the pounding-up device acts upon the work may be varied. A similar result may be obtained by adjusting the rod 39 up or down to vary the presentation of the shoe to the pounding device.

It will be understood from the foregoing description that the pounding device acts on the shoe rst Vby impact and then by crushing pressure to set the stock in flattened down condition on the shoe bottom, the impact and the crushing pressure alternating during the repeated reciprocations of the pounding device to produce an olitective shaping of the shoe bottom for the reception of the outer sole.

The oblique arrangement of the shaft 16 enables the pounding-up device to act properly upon the slightly inclined marginal portion of the shoe bottom without the necessity of rocking the shoe as the different portions thereof are presented to said device.

The means for supporting the boot or shoe while the toe and heel are being pounded-up comprises a jack 40 having one arm provided with a heel pin 42 to ft the usual pin hole in the heel of the last, as shown in Fig. l, and a second arm provided with a padded rest 44 for sustaining the toe of the shoe, as shown in Fig. 2. The jack 40 is connected by a hinge pin 46 to a spindle 48 mounted to slide through a bracket 50 and connected at its lower end to a foot lever 52. The foot lever is pivoted at 54 to a base 56 fixed to the floor, and a spring 60 connects said foot lever to the bracket 50 and yieldingly upholds said lever together with the spindle and the ack with the shoe thereon. The spindle is preferably provided with a guide rib 62 fitting a similarly shaped opening in the bracket to hold the spindle from turning.

The bracket 50 supports a slide bar 70 having ahead 72 provided with an inclined upper face 73, and the spindle 48 has a slot or opening 74 shaped to receive the head of said slide bar, the upper wall 75 of the opening being inclined to coact with the inclined upper face of the head 72. The inclined head 72 of the slide bar enters the opening 74 in the spindle more or less, according to the position of the shoe support, and coperates with the inclined wall 7 5 of said opening for sustaining t-he shoe support at diiferent altitudes. The slide bar is arranged to be actuated, for moving the head 72 in the opening 74 in the spindle, through a lever 76 fulcrumed at 7 8 to ears depending from the bracket 50. The front end of the lever is upturned and extends through a recess in the bracket into an opening in the slide bar, as shown most clearly in Fig. l. A spring 80 connects the rear end of the lever with a hook 82 on the bracket and acts on the lever for forcing the head of the slide bar into the opening 74 of the spindle as far as the position of the spindle permits said head to enter. The spindle and jack are thereby rigidly sustained or lockedagainst depression and this is eected automatically whatever may be the position of the shoe support. The spring 80, acting directly upon the lever 76, exerts sui'icient pressure on the slide bar to prevent the head 72 from being forced out of the opening 74 in the spindle and the shoe support from being lowered by the action of the poundingup mechanism on the work.

For the purpose of retracting the slide bar to unlock the shoe support and permit said shoe support to be depressed for removing one shoe and applying another the foot lever 52 has connection, through an arm 84 on the lower part of the spindle and through a link 86, with the lever 76 whereby said lever may be actuated for withdrawing the head of the slide bar from the opening in the spindle when the foot lever is depressed for lowering the shoe support. The connections between the foot lever and the slide bar are preferably so arranged and proportioned that the slide bar is actuated substantially simultaneously with the actuation of the spindle up or down, and said slide bar and spindle areV moved through such relative distances that the inclined face 73 of the head 72 and the coacting face 7 5 of the opening 74 are maintained in substantial contact at all times and in all positions of the shoe support.

It will be understood that with the construction above described the spring 60 tends to lift the shoe support so that when a shoe has been applied to the support and the foot lever released the shoe support is automatically raised by said spring until the shoe contacts with the abutment 39 and that simultaneously the slide is advanced by the spring SO, or by its connection with the foot lever, for forcing the head 72 more or less into the opening 74 in the spindle, thereby to lock the shoe support automatically in whatever position the abutment 39 may stop the shoe and to sustain said shoe support rigidly in such position. This arrangement is of importance because it is desirable that each shoe be pressed upwardly into engagement with the abutment 39, which is in effect a gage, in order that the shoes may be presented in uniform position to be treated by the pounding-up device. As lasts of different sizes and styles vary in height orthickness, the shoe-support requires to be moved upwardly diEerent distances, and should always be locked at precisely the right height. rThe co-acting faces 73 and 75 form simple and efl'ec-V tive means for sustaining and locking the shoe-support in any desired position.

In the pounding-up operation as carried out with the present machine the workman depresses the shoe support by means of the foot lever 52 and places the shoe with the heel on the heel pin 42, as shown in Fig. l, or with the toe on the toe rest 44, as shown ioo in Fig. 2, according as may be most convenient, and then releases the foot lever. Thereupon the spring 60 lifts the shoe support, carrying the shoe into the range of action of the pounding-up device until the shoe is stopped against the abutment 39, the spring 23 permitting the pounding-up device and rod 16 to yield relatively to their actuating means. As the shoe support is raised through the instrumentality of the spring 60 the slide bar 70 is advanced by the spring and link 86, acting through the lever 76, to force the head 72 of the bar into the opening 74 in the spindle of the shoe support as far as the elevation of the spindle permits. The slide bar thus follows up the spindle, locking it in whatever position it may occupy and rigidly sustaining it against depression by the action of the pounding-up mechanism or by any other force until said slide bar shall be retracted. The advance movement of the slide bar for locking the shoe support is insured by the connection of the lever 76. with the arm 8st of the spindle through the link 86, so that if at any time the slide bar does not respond promptly to the action of the spring 80 by reason, for example, of the accumulation of particles of leather in the path of the bar, said slidebar will certainly be advanced and the shoe support locked as the spindle is raised. The shoe will now be clamped by the shoe support and the abutment 39 between which it may be turned for presenting the different portions of the heel or toe to the action of the pounding-up device 20. It will be understood that the vertical position of the end o-f the abutment 39 determines the relation of the shoe to the stroke of the pounding-up device and that by raising or lowering the abutment the height to which the shoe may be raised by the shoe support will be varied and thereby the pounding-up device will be caused to engage the work earlier or later in its downward stroke.

The shoe support having been elevated to put the shoe into the range of action of the pounding-up device and automatically locked against depression, the workman presses the edge of the shoe firmly against the rest 38 to hold the upper material against the last near the edge of the last and prevent the side of the shoe from being forced outwardly as the upper material on the shoe bottom is flattened down, and he then turns the shoe upon the shoe support to present different portions of the end thereof to the pounding-up device. IThe striking movement of the pounding-up device is directed inwardly away from the edge of the shoe, as described, and therefore draws the upper materialrfarther over the innersole at the same time that it flattens the upper material down onto the innersole. By this means the upper material is caused to conform approximately to the contour of the edge of the last and inner sole.

lVhen the shoe support is in the position shown in Fig. 1 the weight of the toe rest arm actuates the shoe laterally toward the machine to resist the thrust of the pounding-up device inwardly over the shoe bottom and thereby assists the operator in offering resistance to the displacement of the shoe outwardly from the machine. It is to be noted that the side rest 38, by its engagement with the shoe held against it, acts to smooth the upper adjacent to the shoe edge during the operation of the pounding-up device.

Then the pounding-up of that end of the shoe being operated upon is completed the workman actuates the foot lever to retract the slide bar 70 by means of the link S6 and lever T6, thereby unlocking the spindle and simultaneously depressing the shoe support. The shoe may then be removed and the jack tipped on its pivot 4G to bring the other arm thereof into operative position. The other end of the shoe will then be applied to the ack and the pounding-up operation for that end of the shoe performed in the same manner as just described.

It is to be noted that the frame 2 and the bench or table upon which the machine rests are suitably cut away to permit the jack to be turned about its pivot 4 6 as required to place one arm or the other in operative position and that the jack and spindle are provided with coperating stop faces 41, 119 and 41a, 49a for limiting the tipping movements of the jack.

W'hile the invention has been described as embodied in a machine adapted to be employed for performing the pounding-up operation on a shoe after the shoe has been lasted, it is within the scope of this invention to provide mechanism for operating upon shoes at other stages of their manufacture if desired.

rThe shoe support per se is not claimed in the present application, but in some claims certain features of such shoe support are included in combination with the means for operating upo-n the shoe. rlhe invention in said shoe support is claimed in a divisional application Serial No. 540,810, filed J anuary 29, 1910.
