JOSEPH A. GROEBLI, OF NEW YORK, N. Y ASSIGNOR TO THE KUR- SHEEDT MANUFACTURING COMPANY, OF NEW YORK, N. Y., A COR- PORATION OF NEW YORK.

PUNCHING-MAOHINE.

SPECIFICATION forming part of Letters Patent No. 786,890, dated April 11, 1905. Application filed June 5, 1903. Serial No. 160,234.

proving the construction of jacquard-card punching machines shown and described in United States Letters Patent No. 551,544, dated December 17,1895, and No. 627,256, dated June 20, 1899, granted to The Kursheedt Manufacturing Company as my assignee.

In the accompanying drawings I have shown the machine as of the type set forth in United States Letters Patent No. 551,544;

but I would have it understood that I donot' thereby mean to limit myself to this particular type or, in fact, to any type of punchingmachine, but desire to have my claims construed as broadly as the state of theart will warrant.

In the two patents hereinbefore mentioned I have shown a series of pin cylinders or selectors adapted to select certain punches which will determine the direction and extent of individual movements of the fabricframe. As fully explained in the said Letters Patent, it is'important that some means be provided whereby the selectors can be returned to their initial positions, and in Figures 16 and 17 of United States Letters Patent No. 551,544 I have shown means whereby a certain sliding block "a which is connected to a selector, is returned to an initial position (shown in dotted lines in the said Fig. 16) by the movement of a pair of curved levers or tongs n. I have found, however,

that in certain positions assumed by the block the said block is engaged by the levers or tongs with difliculty, and it may sometimes happen that it is not engaged at all.

The object of the present invention is to produce means for restoring the selectors to their initial positions accurately and by a about on the line II II of Fig. I. Fig. III is a horizontal section on line III III of Fig. II, andFig. IV is a plan view of the ends of the tongs by which selector-restoring lugs are moved.

In the drawings, a is the frame of the machine, shown as having depending shafthangers l), which serve to carry the shafts of the selectors. These shafts are constituted by an inner shaft 1, which is surrounded by a hollow shaft or sleeve d. One of the selectors is carried u on c and the other upon d, as set forth in t e patents to which I have hereinbefore made reference. A suitable gear e is carried by or made integral With a sleeve f and is freelyrotatable on the sleeve (1. Mounted upon the said sleeve are two disks h and 1', connected by a sleeve j to a suitable restoring or positionin lug k for restoring one selector to its initia position. The connection of the disks h and '5 with the sleeve may be effected by the set-screw g. Another gear Z and disk 9 are connected by a sleeve m to another restoring or positioning lug 0, the whole being secured to shaft 0 by set-screw r.

A disk p and gear t are suitably united and mounted looselyupon the shaft'c; It will of course be obvious that as the sleeve and shaft b 0 receive motion in order to set or position the selectors for action the restoring-lugs 7c 0 will rotate therewith and will be left in some position other than the normal position, which is an upright position. In the machine shown the selectors are provided each with fifteen pins, occupying, therefore, fif teen different positions. The lowermost po sition of the restoring-lug corresponds to one of the fifteen positions of the selectors, and consequently in the seventh position either to the right or to the left the restoring or positioning lug must rest to one side or the other of a vertical line, as shown in dotted lines in Fig. II. In order to restore the selectors to their initial positions, I have provided a pair of tongs 1 2, having jaws 3 4 5 6. Each member of the tongs is pivotally mounted upon a movable aXis 7, which is actuated by an arm 8, carried upon a rock-shaft 9, receiving its motion from the main driving mechanism of the punching-machine. Each member of the tongs is provided with a pin 10, entering a cam slot 11 in a cam plate 12, carried on the machine, preferably by suitable brackets 13.

The operation of the construction herein shown is as follows: When the punches have been selected and it is desired to return the selectors to their initial positions, the restoring-lug k or 0 will be found in some position other than its initial normal positionto wit, the positions shown in full lines in Fig. II. When it is desired to restore the parts to their initial positions, the arm 8 is by means of the rock-shaft 9 swung downward, and one of the jaws at some point in its travels contacts with the restoring-lug and carries the same with it until the restoring-lug arrives at its initial position, which is the position shown in the dotted lines, at which time the other jaw of the other member of the tongs will have arrived at such position to aid in accurately centering the restoring-lug, the position of the parts in this instance being indicated in dotted lines in Fig. II of the drawings. The path of travel of the jaws from their uppermost position to their lowermost position is shown in dotted lines in Fig. II and corresponds more or less closely to the shape of the cam-slot 11 in the cam-plate 12 that is to say, the jaws drop a short distance vertically and then move approximately 011 the arc of a circle in the path of movement of the lug 0 or 7r.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a selective punching-machine, the combination of a selector-shaft with means for restoring the said shaft to an initial position, comprising in its structure a rotary restoring device and a plurality of means for engaging the same, moving means for the engaging means, and guiding means for the engaging means.

2. In a selective punching-machine, the

combination of a selector-shaft, a restoring means carried thereby a plurality of engaging means for the restoring means, means for moving the engaging means and a cam for determining the path of movement of the engaging means.

3. In a selective punching-machine, the combination of means for moving a selector, a tapered restoring means therefor for restoring the same to an initial position, and means moving on an are for engaging and moving the tapered restoring means substan tially as described.

4. In a selective punching-machine, the combination of a selector-shaft, a restoringlug carried thereby, and means for engaging and moving the restoring-lug to an initial position.

5. In a selective punching-maehine, the combination of a selector-shaft, a tapered restoring-lug carried thereby, and means for engaging and moving the said restoring-lug to an initial position.

6. In a selective punching-maehine, the combination of a selector-shaft, a restoringlug adapted to move the said shaft and means for engaging and moving the restoring-lug to an initial position.

7. In a selective punehing-machine, the combination of a shaft, a tapered restoringlug carried thereby, a pair of tongs adapted to engage the said lug, moving means for the tongs and a guiding means for determining the path of movement of the said tongs.

8. In a punching-machine, the combination of a rotary shaft, a tapered lug carried thereby, tongs for restoring the lug to an initial position, and cam means for determining the path of movement of the tongs.

9. In a punclung-machine, the comhimrtion of a rotary shaft, means adapted to move the saidshaft and constituting a restoring means for restoring the same to an initial position and a plurality of tongs provided with means for imparting to the tongs a movement toward the restoring means on substantially right lines, a divergent movement on an arc and a convergent movement to the point of initial position of the restoring means, substantially as described and for the purposes set forth.

10. In a selective punching-maehine, the combination of-a rotary restoring means, a plurality of means for engaging the same, normally located outside of the circle of movement of the restoring means, and means for moving the engaging means, first in a substantially radial direction and then in an approximately circular path substantially as set forth.
