A TTOHNEYS qlA/VEIVTO BY I UNITED STATES PATENT OFFICE.
CHARLES W. GRAHAM, 0F ROME, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO AMERICAN CAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
To all whom it may concern:
Be it known that I, CHARLES W'. GRAHAM, residing at Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Feeding Mechanism, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to feeding mechanism.
One of the objects thereof is to provide feeding means of durable and inexpensive construction, simple action and ready manipulation.
Another object is to provide means of the above type adapted to act efficiently, either automatically or by hand, and to be readily changed for use from one to the other of these methods of feed.
Another object is to provide simple and practical means for varying the power or speed of the feeding mechanism.
Another object is to provide means of the type last above-mentioned which shall be independent of the power or speed of the machine.
Other objects will be in part obvious and in part pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the mechanism here inafter described, and the scope of the ap plication of which will be indicated in the following claims.
In the accompanying drawings, wherein is shown one of various possible embodiments of my invention, Figure 1 is an elevation of the same partially broken away so as to disclose the mechanism more clearly. Fig. 2 is an end elevation, partially in section, along the line tr-20 of Fig. 1. Fig. is a side elevation of parts shown in Fig. 1, the same appearing in another position.
Similar reference characters refer to similar parts throughout the several views.
As conducing to a better understanding of certain features of my invention, it may first be noted that, in mechanism of the general type with which this invention deals, unless means he provided for quickly and conveniently throwing off the power, there is a greater or less likelihood of personal injury to the operator of the machine, or of waste Specification of Letters Patent.
Application filed June 26,

of material owing to the same not being properly acted on thereby. It may also here be noted that unless means are provided to permit a free hand feed, when desired to meet certain conditions of work, the breadth of utility of the same is considerably diminished. Another fact of interest at this point is that I have found that it is often desirable that the feeding mechanism be operated only at the desired times and with the desired speed and yet the operator be relieved of the severe manual labor attendant upon the hand feed. The above defects are eliminated and the above and other advantages attained in constructions of the nature of that hereinafter described.
Referring now to Fig. 1 of the drawings, there is shown a frame 1 having an extension or bed 2 upon which is adapted to slide a carriage 3, the same being guided in such movement by means of sleeves 1 formed thereon and adapted to reciprocate upon a guide rod 5. J ournaled within frame 1 is a shaft 6 having fixed thereon a driving pul ley 7 adapted to be driven from any desired source of power. Upon shaft 6 is fixed a pinion 8 adapted to drive through an idle gear 9 and a gear 10 a shaft 11 upon which are preferably positioned cutters 12. The details of the latter mechanism are not herein shown, as they form in themselves no part of the present lnvention, it being suflicient merely that the material in this illustrative embodiment be adapted to be fed toward them upon the bed 2 by means of the frame or carriage 3.
Upon a pin 13 formed on or secured to the frame 1 is mounted a lever 14, upon the free end of which is journaled by a stud 15 a cam 16. This cam is provided with an outer surface adapted to co-act with and frictionally engage a driving wheel 17 upon the shaft 6. In this illustrative embodiment, the face of wheel 17 is recessed so as to embrace the corresponding portions of cam 16 and thus transmit power thereto at a rate depending in part upon the force with which these parts are pressed into engagement. The free end of lever let extends for a considerable distance adjacent the carriage 3 and is provided with a slidable weight 18 by the adjustment of the position of which, the pressure with which the wheel 17 and the cam 16 engage one another may be varied.
Upon the frame of the machine is positioned a support 19 having an inclined upper surface and adapted, upon the weight 18 being pushed against the same, to raise this part and to force the wheel 17 and cam 16 out of engagement one with another. Likewise, mounted upon pin 13, as by sleeve 20, resting upon the hub 21 of lever 14:, is a lever 22, provided with a pin 23 and roller 24 adapted to rest within the groove 25 in cam 16. The remaining end of this lever extends upwardly toward the carriage 3 with which it is connected, as by link 26.
The operation of the above described embodiment of my invention is substantially as follows: Assuming that material of a proper character be placed on the carriage or feeding frame 3 and that it be desired that the same be fed automatically toward the cutters 12, or other tools which are to act thereon, the weight 18 is moved along the lever 14 to the outer portion thereof so as to move the cam. 16 into forcible engagement with the friction wheel 17. In this manner, the cam is driven by the friction wheel 17 and the pin 23 is forced toward and away from the stud 15 upon which the cam is mounted, the
It will thus be seen that I have provided means well adapted to accomplish the several objects of my invention and attain, among others, the advantages hereinbefore the machine is a highly advantageous fea-' ture. The ease with which the feed may be changed from manual to automatic will also be clearly apparent and the many advantages thereof obvious to those skilled in the art with which this invention deals.
As many changes could be made in the above construction and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
