it'known that I, FREDERICK O. TYLER,

residing at '(llecfelarld, in the county of Cuyahoga and .15 nuts to the machine,

' shown and described and Y to get such a feed when a hopper is run low feeding mechanism and Fig.- 2 is a side secproximately perfect feed for the nut blanks consists of a substantially disk shaped part useful Im rovements in Automatic Feed- Hoppers or Nut-Tapping and other Machines, and do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which vit appertains to make and use the same. if

My invention relates to improvements in nut-tapping machines, and particularly in the means for feeding the blanks or blank all substantially as particularlypointed State of Ohio, have invented certain newand out in the claims. l

In the accompany/mg drawings Figure 1 1s a cross sectional elevation o f my improved tional elevation thereof atright angles to Fig. 1 and on a line corresponding to x, r, Fig. 1. Fig. 3 is a cross section on line Iy, Yy, Fig.`2, and Fig. 4 is a perspective view of the combined feeding disk and agitator in detail.

The importance of having at least an ap- 1n a machine of this kind can scarcely be overstated, because there are so many dif-h culties encountered in providing a uniform and certain feed for heavy angular Aobjects like these blanks, and Without- Which the best of tap ing machines would be more or less of a fai ure. Thus, for example, it is one thing to get a sustained feed When a hopper is full of blanks, and quite a different thing or practically emptied. Obviously, also, any construction to be universally acceptable must be adapted to meet both these vconditions successfully, as Well as others arising in the delivery of the blanks to the machine, such as providing againstany banking up or blocking of the blanks in their travel to the machine. Tothese ends l construct a hopper A of the sha-pe substantially as shown with a narrowed space at its bottom be! tween parallel side Walls a and a and from which there leads a preferably curved throat or outlet a2.

The feeding device D is located in t-he narrow space bet-Ween said Walls a and a and D, having a. plain flat rear side provided with head 10.

a shank or stem d supported in a bearing at which the disk has a limited rocking move# ment, and said device is further provided with a shoulder 2 running in a straight line across its .front lower inner portion or side and a substantially V shaped notch 3 in its edge and top opposite said shoulder. A gage plate VC isinteiposed between the. said the bottom of hopper A and on on through i feeding device or disk D and Wall/zand is supported on or by adjusting screvvs c c through said Wall adapted'to fix the limits of the space laterally between said parts ac-I cordlng to the thickness of the blanks and into which the nut blanks b are adapted to drop edgevvise and temporarily rest on said ledge or rib 2 preparatory to belng discharged into throat a?, as said disk or device is rotated, and approximately to positionas seen 1n Fig. 4. The extreme of rotationof the disk to the left is seen in Fig. 2, and the limit of rotation or rocking thereof is equiva lent to about a quarter. of a revolution. When rotatlon occurs to dlscharge the blank it is toward the right, in which case the blanks accumulated on ledge 2 will be thrown edgewise into throat or passage a2 in the line of feed.

By reason particularly of notch 3 the disk operates as an agitator for the blanks and as'4 sists in bringing the blanks into feeding relations both asv to the upper portion of the throat indicated by S through which some of the blanks are alined for feeding and also in relation to ledge or shoulder 2 to which other blanks come through 4notch 3. also, the immediate edge d" of notch 3 is somewhat below edge a* of the hopper, Which leaves a clear Way dovvn the side of the hopper onto ledge 2. A strip G is laid in the throat or neck' of outlet passage af" and is adjustable by set screuv g to ix the size ot the throat according to the size of the blank. Discharge spout H likewiseV is shown as astened by screw g.

Power is communicated to disk D to rotate or rock the 'same thiough operating connections comprising in this instance a crank arm gf rigid on shaft d, and tubular coupling J engaged at one end With said arm and into which extends a. connecting rod L, having a A threaded nut or .cap 12 is screwed inthe end of said coupling, and stili springs 13 and 14 are operatively engaged With said rod on' opposite sides ,of its head and are of such .strength orstiffness that in ordinary operations they serve to convey ro- To this end,

. tary power to disk D but if said disk be accidentally blocked against rotation by a possible combination ,of the'V nut blanks or for `other causey the said springs will yieldiand Furthermore, it

prevent breakage of parts, occurs if there be occasional blocking against rotation one way or the other, the opposite way will be found free, and then on the return stroke thev obstruction will be found broken because of the agitation ofthe entire mass u oi)blankswhich bring relief to the congested corner, if this belthe cause of trouble, lwhich is probable. In this way two channels are provided forsupplying blanks to the machine, one into throat a2 through the openingY lower edge to feed the blanks and at its top edge to `agitate the same;
