Fig. 8 is a view of ing of a rotary plate upon which is mounted the rotary head for attaching top lifts and back to back two or more jacks, the plate slugging. Fig. 9 is a view of the rotary head and jacks being so arranged that there are used'for attaching top lifts only or without 20 always two in position beneath the heelthe slugging attachment. Fig. 10' is a view blank-attaching and top -liftattaching deof the top-lift holder attached to the spankervices, so that upon the reciprocation of the blocks of the rotary heads shown in Figs. 8 cross-head a heel-blank is attached to one and 9. Fig. 11 is a plan view of a rotary shoe and a top lift to a previously-attached jack-plate and portions of four jacks sup- 2 5 heel-blank, and the next rotation of the jackported thereby. Fig. 12 is a detail view, in plate moves the shoe with the attached heelvertical section, to illustratethe rotary heads blank under the top-lift-applying device as turned by two turning devices. while another jack is brought into position A is the frame of the machine. It has the under the heel-attaching device to receive sides a a and the cross-bed a", preferably'inc the heel-blank, and thus at every reciproeategral with the sides.

It is reciprocated by blind-nailed heel, which, however, has been means of the shaft 1), cranks b, and side consubjected to two operations. First, it has had necting-rods o The distance between the a heel-blank attached to it by one set of opuprights a a of the frame is sufficient to per- 5 crating devices and then the top lift. mit the rotation of the jack-plate O and jacks I have represented the heel-blank-attachmounted thereon. This jack-plate preferably ing and top-lift-applying devices in the form is circular in shape and is pivoted at c tothe of rotary heads attached to the reciprocating bed on aline directly central between the top-. cross-head and automatically revolved, but lift and heel-blank attaching devices carried 0 I would not be understood as limiting myself by the head B. It is represented as carrying l to this construction, as the cross-head may the jacks 0 0 These jacks are mounted have one arm only for the heel-attaching deupon plates 0 and are movable toward and vices and one arm for a top-lift-applying defrom the center a of the plate 0 and are also vice, but I prefer as a rule to use the rotary verticallyadjustable. The horizontal move- 45 heads, as this furnishes anumber of arms, ment is given them for the purposes of ad- 5 each of which supports a heel-blank holder j ustment. The plate may have more than and heel-blank and top-lift holder and top two jacks, as represented in Fig. 11, if delift, and which are moved automatically sucsired.

The head E is the one used for attaching loaded heeLblanks, and each arm supports a heel-blank-applying device preferably consisting of the gang of drivers 6 and the templet e similar to that described in my application for patent filed November 11, 1889, and each of the arms of the rotaryhead E supports a spanker e and a top-lift holder preferably comprising the two breast cornergages 6 e movable from and toward each other by right and left screws 6 and the backstop e comprising a plate having a V-recess e and attached to two side rods or bars 6 playing in side recesses in the spanker-plate, and springs 6 which draw the V or backstop toward the breast corner-gages. There may be used also upon the spanking-arms slug-driving mechanism, as represented in Fig. 8, and comprising the gang of slug-drivers e and a movable spanker-plate e having the holes through which the slugs are driven and yielding in relation to the arm which supports it and having a top-lift holder like the one above specified.

I prefer when the rotary heads are used that they be revolved automatically, and they may be fastened upon the same shaft and revolved by one turning mechanism f, as represented in Fig. 2, or there may be two turning mechanisms f f as represented in Fig. 12, or each may be mount-ed upon the straight shaft and turned by its respective mechanism, as desired.

In use loaded heel-blanks and top lifts are placed upon their respective blocks when they are uppermost by a boy or attendant who stands upon the platform in a position to enable him to so place the top lifts and heel-blanks. The slugging-spanker may be loaded with slugs in any suitable manner.

In operation the operator places ashoe upon the last or work-support, and the heel-blanks and top lifts being fed by an attendant to the arms of the heel-blank and top-lift attaching devices the machine is started and makes one reciprocation, and a heel-blank is attached to the shoe. Thejack-plate is then turned, movin g the jack having the heeled shoe under the top-lift-applying device. Another shoe is then placed upon the jack brought into position beneath the heel-blank-attaching device by the operator, and the next reciprocation of the machine attaches a heel-blank to that shoe and a top lift upon the previously-attached heel of the other shoe, andv the jack is again turned, the first jack brought into position before the operator, the finished shoe removed from it, another unheeled shoe substituted, and the machine set in operation and a heel-blank attached to the shoe and a top lift to the heeled shoe under the top-liftapplying device, and from that time on every reciprocation of the machine completely heels the shoe and also slugs it, that is, at every reciprocation a completed shoe is in condition to be removed from the machine and another one unheeled to be substituted for it.

As the machine is operated from one front only and the shoe which is receiving the top lift is out of the direct control of the operator, it is necessary, or desirable at least, to employ in connection with the last or work-support shoe holding and centering devices to hold or look the shoe upon the last or work-support and hold it so locked while the jack is being turned or rotated, and also while the machine is operating, and Ihave represented each jack as provided with shoe centering and holding devices, comprising in substance a sleeve M, arranged to slide or be vertically moved upon the jack-post by means of an adjusting-nut m, (see Fig. 1,) which screws on a thread m formed on the jack-spindle. The sleeve is prevented from turning on the jack-post by a pin m which enters guiding-slots m in the jack-post, and also serves to connect the sleeve with the jack-spindle, so that the nut m serves to simultaneously adjust the jackspindle and last or work-support mounted thereon, and also the sleeve or support for the shoe holding and centering devices. The sleeve carries at its rear end the long supports m for the vertical rods m. The two rods are-connected together by segment-gears m m whereby the movement of one causes the operation of the other. There is secured to one of the rods m a handle on and a ratchetwheel on, and there is mounted upon the handle m a pawl m to engage the ratchet. At the upper end of each rod m is the shoe centering and holding arm m extending forward from the end of the rod, having a thin curved edge m to enter the rand crease and a shoulder m to bear against the counter. The shoe is mounted upon the last or worksupport when the fingers or shoe-holders are wide open, and they are then closed upon the shoe, the edges 072- of the guides entering the rand crease, and the shoulders m bearing against the counter, and the fingers or holders are held in this position by the pawl and ratchet, and this looks the shoe firmly upon the last or work-support and insures its remaining in the same position during the movement of the jacks and the operation of the machine until the shoe is returned to the operator with the heel-blank and top lift attached.

It will be seen that the curved edges of the holding-arm are shaped so that they not only bear against the side of the shoe at the heel, but also at the back, and therefore press the shoe forward against the back end of the last or work-support as well as clamping its sides.

Power is represented as applied to the ma.- chine by means of the main shaft N, the pinion n thereon, the gear-wheel n on the shaft 1). The main shaft N carries the driving-pulleyn which is also a fly-wheel. The pinion 'n is free to rotate on the shaft N, and has the member n of a clutch secured to it. There is. attached to the shaft N by'a feather or spline to slide thereon the other member n of the clutch. It has a groove of, which receives rolls a, carried by the forked lever oi This lever is pivoted at n and supports a latch-lever n. A spring n operates against the movable member 01 of the clutch through lever of. The gear n has a stop-cam projection n, and the latch-lever n is of a shape and size to be brought into the path of the movement of this cam-stop, and is held in such path by a spring It. The opposite end of the latch-leveris connected with the treadle n by a connecting-rod n.

The operation of the device is as follows: The driving-wheel n and the member a of the clutch constantly rotate. The machine makes but one reciprocation, that is, there is one revolution of the shaft 1), and to start the machine the treadle is depressed, lifting the end of the lever n from contact with the stop a on the gear n. This permits the spring 11, to force the member 11* of the clutch into engagement with the member n on the pinion "n, and this engagement is maintained during one revolution of the gear n and until the cam-stop n comes into contact with the end of the lever n, which has by the spring n been brought into position to be operated by the cam-stop, and pushes the lever n sufliciently to cause it to disengage the member n of the clutch from the member when the machine comes to rest. It will be observed that this stop-motion mechanism is all contained between the two side frames of the machine.

It will be seen that the plate C furnishes means whereby the jacks are made interchangeable in relation to the duplex nailing devices,and the jacks are attached to the plate preferably by means of cap-plates,so that they may have a sliding movement thereon both for the purposes of adjusting their position horizontally, and also, if desired, for the purpose of drawing them outward from the nailing devices, and in Fig. 3 I have shown the plate 0 as provided with the adjustable stops 0 for limiting or regulating the degree or extent of horizontal movement of the jacks, and also for the purpose of adjusting them upon their carrier-plate in relation to the nail-driving devices.

It will be seen that each spanker-block has a horizontal adjustment upon the end of its holding-arm,\vhereby the position of the toplift holder and centerer is adjusted or varied in relation to the heel-blank.

It will be observed that the arms of the head E may also be used for driving slugs or additional nails into a previously-attached heel-blank.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1.
