RIVET-FEEDING MECHANISM.
Application filed May 27, 1927. Serial No. 194,630.
This invention relates to rivet feeding mechanism such as used to feed rivets to the operating plunger of a rivet setting machine.
An object of the invention is to provide mechanism that willfeed the rivets smoothly and rapidly without congestion or jamming.
In rivet feeding mechanism now in use the rivet has a tendency to fall over on its side just as it is being fed into the rivetreceiving pocket, and this action causes jamming of the machine. The present invention avoids this difficulty by providing an "improved feedway that guides the rivet in such a Way that it maintains a position substantially normal to the feedway and hence falls upright into the pocket. This is done by forming the lower end of the feedway with a part of reduced depth that closely engages the head of the rivet and holds it against tilting movement, thereby insuring its proper engagement wit-h the rivet-receiving pocket.
While a preferred form of the invention has been disclosed for purposes of'illustration, it should be understood that various changes may be made in the structure with out departing from the spirit and scope of the invention as hereinafter set forth and claimed.
In the drawings; v
Fig. 1 is a plan view of the lower face of a feedway embodying the invention;
Fig. 2 is a section on line 22 of Fig. 1;
Fig. 3 is a section on line 3-3 of Fig. 1;
Fig. 4 is a section on line 44 of Fig. 1;
Fig. 5 is a perspective of the cut-off slide.
The device disclosed herein is'an improve ment on the structure shown in my Patent No. 1,480,577, issued J an. 15, 1924. In the patented machine the slot for feeding rivets to the holding pocket is of uniform depth throughout its length, and as it must be deep enough to permit free passage of the rivets under force of gravity, the rivet heads fit so loosely therein that they tend to fall over on their sides just as they are leaving the lower end of the feed slot. In the present invention the lower end of'the feed slot is of less depth than themain part of the slot, and the rivet head is thus firmly held against tilting as it holding pocket.
is being fed to the Referring to the drawings more specifi cally, the reference numeral 10 indicates the main part of the feedway in which is formed a T-shaped feed slot 11. A nose piece 12 is secured to the lower end of the feedway,
Below the groove 13 the plates 19 and 20 are fastened to the nose piece and carry flanges 21 and 22 which cooperate to form a T-shaped delivery slot 23. The flanges 21 and 22 being thicker than flanges 17 and 18, the lateral branches of the delivery slot are of. less depth than those ofthe feed slot, and hence the head of the rivet will fit more snugly in the delivery slot and there will be less'possibility for the rivet to tilt.
The cut-off slide 14 is formed with a T shaped slot 24 whichis adapted to transfer the rivets from the feed slot to the delivery slot, and the lateral branches of the slot 24 have sloping lower walls,as shown at 25 in 'Figs. 2 and 5, whereby the rivet heads move slot formed therein, a T-shapcd delivery slot if offset from the feed slot, the lateral arms of the delivery slot being of less depthfthan those of the feed slot and being of uniform depth throughout their length, and means for transferring a rivet from the feed slot to the delivery slot. 7
2. Rivetfeeding mechanism including an inclined feedway having a T-shaped feed slot formed therein, a T-shaped delivery slot offset from the feed slot, the lateral arms of the delivery slot being of less depth than those of the feed slot and being of uniform depth throughout their length, and a slide for transferring a rivet from the feed slot to the delivery slot. I
inclined feedway having a T-shaped feed slot formed therein, a T-shaped delivery slot offset from the feed slot, the lateral arms of the delivery slot being of less depth than those of the feed slot and being of uniform 5 depth throughout their length, and a slide for ,transferringra rivet from the feed slot to the delivery slot, the slide having a T- shaped slot therein the lateral branches of the slot having their lower Walls inclined to guide the rivet heads from the deep feed 10 slot to the shallow delivery slot.
In testimony whereof I aflix my signature.
