Application filed December 8, 1915. Serialilc.l 65,866.
To all who'm t may concern:
Be it known that I, ALBERT X/IU'rsCHLIJR,y
a citizen of thel United States, residing at Rochester, in the county 'of Monroe and*l State of New York, have invented certain v'new land useful Improvements in Automatic-v Feeding Machine-Tools,`of which the following is aspecification.
The object of this invention is to provide a machine that Willautomatically feed and hold blanks in position for machinev operations such as milling, drilling, etc.
This and other objects of the inventionA will be fully illustrated in the drawings,
describedin the specification and pointed out in the claims at the end thereof.

' is left blank. t
lcan be Varied within considerable llmits.k As. will presently be explained, the mllls or.
is driven by 'a belt. On thisl shaft is keyed a worm 3 which engages withand drives the worm wheel 4, keyed to the shaft 5. The 'shaft 5 and parts associated therewith are Patented Mar. 6, 1917.
carried below the auxiliary frame 48.- ()n f this shaft are carried the canrwheels 6, 7I and 8 fastenedthereto by set screws.` Also positively fastened to the shaft is the gear wheel 9 which meshes with the gearwheel 10, mounted to rotate on a stud 11 carried on a bracket 12 which is integral with thel frame of the machine. vOn the gear wheely 10 is acrank pin 13- with which engages a connecting rodr 14, which connecting rod, aty its forward end, engages with a crank 15 which is mounted to rock on the shaft 16 supported in the' frame of the machine. Onv this shaft is loosely mounted the sprocket wheel17 to-,which `is rigidly fastened the ratchet-wheel 18. On the crank 15 is provided a boss in which is mounted to slide radially. a spring pressed pawl 19, vwhich pawl rides over the ratchet wheel when the connectingrod 14 is moved to the right in Fig. 3 and-engages the ratchet wheel and causes the rotation-thereof and that'of the provided with an 4adjustment 2O by which it may be lengthened orlshortened and by this adjustment theposition in which the crank The connecting rod, is y 15 is left at the end of the stroke may be vari-ed. This in turn, 4effects .the position in whichthe stock is placed during the cuttingV 1- or the milling operation.
On the opposite end of the frame is carried shaft 21 on which is mounted to rotate a sprocket wheel 22. Over -thesprocket wheels 17jand 22 travels thesprocket ch'ain 23.` This .sprocket chain is .what is ordinaril known as a carrier chain Aoncertain` links of which are carried brackets 211. At' i tached to these brackets by screws .(shown in Fig. l) are the carriers 25 which carriers are recessed at 26 to` receive the brackets.
and the preceding and the following link l This` arrangement, however,
cutters on this machine ,are preferably) worked in palrs and the machine 1s there-,3,1
'fore arranged sowthat two, pieces of' ,stoclcr' can be carried together and worked ,OIL-21115219.;
vlocked in .place asy will now be described.
lthe piece of stock 32` shown in Fig'. 12,
which, in this case, is intended to form part of a hinge used to join the parts of a shoe last. T-he half round opening at the bottom of the pocket serves to hold'the stock so that it willbe promptly positioned to Abe The piece -32 is round or cylindrical and one half .of its thickness is cut away atnthe Y' bottom forming a flat bearing surfae33 Thel thereon which is perforated at 34. shape of the holder is such that the pin is held with this perforation extending longitudinally of the slide. The slide 28 is formed at-one end with a cam 35 and at the Aother end with a pin block 36 having a pin 37 integral therewith. The slide 28 is adapted-to move to the right from the position shown in Fig. 13 to engage the pin 37 with the opening '34 in the stock 32 and lock it in the holder 29. This operation of the slide 28 is secured as follows:
On each end of the carrier 25 is formed the projecting lips 38 and 39 which are adapted to engage with the grooves 40 and 41 formed in the frame of the machine, along which the carrier frames are adapted -to travel as they are drawn by the sprocket chain.
On top of the frame of the machine is provided the bars 42 and 43, on top of which in turn areA carried the plates 44 and 45, which plates project toward each other, an opening being left between them through which the piece of stock 32 can travel as it is carried along by the chain. Under this slot travelsV the holder 29 so that when the stock is positioned therein it will travel along the slot. Fastened to the under side of the plate 45 .is the cam 46 having a beveled edge 46 at each end thereof which engages with the cam 35 carried on the slide and by which the slide is moved from the position shownv in Fig. 13 to the position shown in Fig. 10 and by this movement the pin 37 engages with the opening 34 in the stock 32 and locks it in place. The plate 44 may, if desired, be omitted. The bars 42 and 43 may be cast integral with the frame instead of being sep-- arately added thereto.
- The stock is locked in position by the forward movement of the chain, the movement of the chain' being from the left to the right in Fig. 4, the cam 46 being stationary with the frame and the cam 35 moving with the chain. As will be seen in Fig. 4 the cam 46 extends from one side past the middle of the machine to a considerable distance on the opposite side and during the `travel of the guide frame and slide past this cam the stock will be held locked in position. Where the .cam 46 ends the cam 47 begins and this cam f Mounted transversely of the machine is the auxiliary frame 48 on which. are mount-- ed to slide the two heads 61`and 62'. On the head 61 are mounted to rotate the two shafts' 51 and 52 and on the head 62 are mounted to rotate the shafts 49 and 50. On each of these shafts is carried a spira-l gear. Mountgether for this purpose.
Clamps are provided on 'the main frame l A which clamp the stock between them before the cutters operate on the stock and the mechanism by which the clamps and the now be described.
The cam wheel 6 carries thereon the cams 67, 68 and 69. Mounted in the main frame A and passing through the transverse frame 48 is the shaft`70, on the bottom of which is 'carried the Acrank 71 having a crank pin 72 at the end thereof with an antifriction roller 73 mounted to rotate thereon. This crank pin l7 2 is engaged by the cam 67 which causes the crank 71 to swing to la predetermined position and is held in that position while the cam is passing it: On top of the shaft 7 O is anY eccentric or cam 74 which engages with the vise jaw '75( On the cam wheel 8 is placed a similar cam 67 which engages with a similar crank 71, shaft 70, eccentric 74 and jaw 75 and as the cams 67 rotate in unison the jaws oper- 'ated thereby will move together simulta- Vcutters are moved forward'and back will...
by the nut 78 and the other end carrying the antifriction roller 79 which engages the cam the mills or cutters that operate to cut the stock.
Similar cams oppositely placed.are carried upon the cam wheels. 8 andengage with the pin 76 to drive the head 62 forward, causing the stock to be'cut on the vopposite side at the same time. After the cutting opv eration of the mills is completed the cams 69 on the cam wheels 6 and 8 operate on the pins 76 to draw the heads A61 and 62 back,
after which the cam 80 on the cam wheels 7 operates on the antifriction rollers 81 of the cranks 71 to `rock them in the opposite direction, releasing the vjaws 75 which are then drawn in the reverse direction vby thev 'springs 82.
To limit the movement of the heads 61 and 62, adjusting screws 183 are provided which travel therewith and make contact with the cross frame, limiting themovement of the heads and the movement ofthe cut'- ters carried thereby. 0
After the operation of the cutters 1s completed the' intermittent travel of the chain carries thefcarriers past the cam 46 and to the cam 47. The cam 47 then acts upon the cam 35 to move the slide in the opposite direction and disengages the pin 37 from the stock. lAs the chain continues to travel intermittently the guide frame and its slide will travel around the sprocketv wheel and become inverted and while inverted the stock is dropped from the pocket or at any time it may be blown therefrom by a blast of air or an equivalent device.
The operation of my machine is as follows:
The pulley 2 will be driven continuously and the chain will be fed intermittently yas above described, and a piece of stock is placed in each pocket by the attendant of the machine. The intermittent feeding of the chain will bring the guide. frame and slides successively first into contact with the cam 46 by which the stock which had been previously placed in the holder, will be locked in position and will be advanced by successive steps until it is positioned before the cutters, at which point the continuously rotating cam wheels 6 and 8 will first cause the stock to be clamped in place and will then advance the cutters to operate thereon, after which the cutters will be withdrawn and the jaws of the clamp will also be withdrawn, after which the stock is again advanced until the cam 47 operates to release the stock, after which it can be removed from the machine by hand or by gravity or in any other suitable way.
