JACOB F. GEE, OF FRANKLIN, MASSACHUSETTS.

CARD-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 590,541, dated September 21, 187.

Application filed May 10,1897- serial No. 635,775. (No model.)

To all whom it may concern.-

Be it known that I, JACOB F. GEB, of Franklin in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Card-Feeding Machines, of which the following is a description sufficiently full, clear, and exact to enable those skilled in the art to which it appertains or with which it is most nearly connected to make and use the same.

This invention has relation to the means in a card-feeding machine which control the movement or position of the stock or material on the feed apron or table after it is discharged from the scale and until it is received under the patter or paddle. The .pusher which moves the stock forward on the feedapron under the patter is operated by intermediate mechanism from the wheel or gear which aotuates the scale-discharging means. The said intermediate mechanism consists of a pusher arm or lever pivoted on the frame of the machine at its lower end and connected loosely in like manner with the pusher at its upper end. The said arm is actuated by means of a pusher-rod or pitman suitably connected at one end therewith and pivoted at the other end upon awrist-pin on the gear before mentioned. pusher was operated or moved continuouslythat is to say, there was no appreciable dwell at any point. limit of its movement it began its return. The result of this mode of operation has been to allow some of the stock moved up by the pusher to the patter at times to fall back on the table orfeed-apron when the pusher commenced to return before the said stock was evenly taken by the patter, so that some stock of the prior scale discharge remained behind the patter or the apron at the next succeeding discharge. Furthermore, it not infrequently happened that when the scale discharged the pusher had moved forward to some extent, so that some of the stock fell upon or behind the pusher.

It is the object of my invention to provide simple means whereby the pusher may be caused to dwell for a considerable time at both limits of its movements, so as to avoid the objections and mischief mentioned.

To the foregoing ends my invention con- Under this construction the As soon as it reached either' I sists in providing the pusher-bar or pitman at one of its ends with a slot of requisite length, in which the connecting-pin works, so that there will be lost motion in the means operating the said bar or in the bar acting upon the pusher, whereby the dwell at both extreme limits of movement of the pusher, as aforesaid, is secured, all as I will now proceed to describe andclaim.

Reference is to be had to the annexed drawings, and to the letters marked thereon, forming a part of this specification, the same letters designating-the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure 1 is a side view of a card-feeding machine equipped with the usual mechanism so far as is necessary to a clear understanding of my invention. Fig. 2 is a view of a part of Fig. 1, showing the pusher and its actuating means in a diiferent position from that in which they are portrayed in Fig. 1. Fig. 3 is a view of part of the opposite side of the machine from that shown in Fig. 1.

In the drawings, a designates the feed-box.

b and c are the spike-apron roll-shafts, connected and operated, the one from the other, through the medium of the vertical shaft 61.

e is a strap surrounding and actuated by an eccentric on the shaftd, which strap is pivotally connected at one end to a pitman f, the latter having an adjustable pivotal connection with the arm g of the patter or paddle h, so as to operate the latter so as to cause it to pat and smooth down the surface of the wool on the feed apron or table 1.

j is the gear, equipped with means forefiecting the discharge of the scale.

k is the change-gear, meshing with the gear j to regulate the speed at which the latter is driven. A wrist-pin Z on the gear j connects one end of the pusher-bar or pitman m therewith, the latter being adjustably connected at its opposite end to a rocker-block or swivel n, which is in turn adj ustably connected with the pusher-armo, secured at its lower end to a rock-rod 1), journaled in the frame of the machine, the said pusher-arm beingprovided at its upper end with a slot q.

r is the pusher, adapted to be moved to and fro on the feed apron or table 2'. The pusher is provided at its opposite ends with pins 15 2f,

which extend through the slots U it, also on opposite sides ofthe machine, the former pinextending into the slot q of the arm 0 and the latter extending into the slot g of the arm 0, secured at its lower end to the rock-rod p on the side of the machine opposite to that atwhich the arm 0 is connected therewith, as is shown in Fig. 3.

With the construction just described it will be understood by those skilled in the art that the machine will have a mode of operation which will actuate the patter and pusher, so far as explained, in the usual manner.

Coming now to the real improvements made by me, it is to be explained that the pusherbar m is provided in its rearward end with a slot '0, through which the wrist-pin Z extends, so that there is considerable lost motion in the operation of the pusher by the wrist-pin at both extremities of the pushers movement, causing an appreciable dwell when the pusher is moved up to the patter, so that the stock shall be completely taken by or fed under the patter before the pusher starts back, avoiding the falling back upon the feed table or apron of any portion of the stock crowded forward by the pusher and causing another dwell when the pusher moves back, so that the discharge of stock from the scales may fall fully in front of the pusher, avoiding all of the objections hereinbefore mentioned. It is to be noted that both ends of the pusher are moved in unison through the medium of the rock-shaft p and pusher-arms 0 o.

It is to be noted that with my improvements moves more quickly than it would be moved under the said former constructions. This feature in the mode of operation of my improvement has the advantage over the prior art in that the pusher is made to do its work completely and for an appreciable length of time remain back out of the way for the feed apron or table to receive in front of the pusher the full complement of stock discharged from the scale.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is In a card-feedin g machine the combination with the pusher and patter, of the wheel and its wrist-pin, the pusher bar or rod provided with the slot 1; in which the wrist-pin loosely operates with a lost-motion effect at both the extreme limits of its movements, and operative connections, as set forth, between the said rod. or bar and the pusher.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 30th day of April, A. D. 1897.

JACOB F. GEE.
