This invention relates to rivet feeding mechanismsueh 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 orjamming.
In rivet feeding mechanism now in use the rivet has a tendency to fall over on its side just asv it is being fed into the rivetreceiving pocket, and this action causes 1amming of the machine. The present invention avoids this difiiculty by providing an improved feedway that guides therivet 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 with 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 Without departing from the spirit and scope of the invention as hereinafter set forth and claimed.
In the drawings: 7
Fig. 1 is a plan of the lower side of a rivet feedway embodying the invention;
Fig. 2is a section on line 22 of Fig. 1.
Fig. 3 is a perspective View of one of the plates forming part of the feedway;
Fig. 4 is a section on line 4-4 of Fig. 1;
Fig. 5 is a section on line 55 of Fig 1;
Fig. 6 is a section on line 6-6 of Fig. 1.
The device disclosed herein is an improvement on the structure shown in my Patent No. 1,480,577, issued Jan. 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 the main part ofthe slot. and the rivet head is thus firmly held against tilting as it is being fed to the holding pocket.
R rr ng to t d awing m r pa t ularly, the reference numeral 10 indicates the lower part of the feedway, to which is secureda nose piece 11. A T-shaped feed slot 12 extends along the lower face of the feed- Way, and plates 13 and 14 fastened to the nose piece by screws 17 have overhanging flanges 15 and 16 that cooperate to form a continuation of the feed slot12.
At the lower end ofthe nose )iece the plates 18 and19 have overhanging anges 20 and 21 that form a T-shaped delivery slot 22 offset from the feed slot 12. Screws 23 hold the plates 18 and 19 inposi-tion. The flanges 20 and 21 are thicker than the flanges 15 and 16, as will be clear from Figs. 2, 5 and 6, and hence the delivery slot 22 is of-less depth than the feed slot 12. The upper ends of the flanges 20 and 21 are formed with inclines 24 and. 25 that lead from the full depth of the feed slot to the shallow delivery slot. A cutoff slide 26 operates in the same way as the cutoff slide of the patent above mentioned to transfer a single rivet from the feed slot to the delivery slot at each operation of the machine.
I claim y 1. A rivet feeding mechanism including an inclined feedway having a T-shaped feed slot formed therein, a T-shaped delivery slot offset fromthe feed slot, the lateral arms of the T-shaped delivery slotbeing of ap uniform depth throughout a major portion of their length, saiddepth being lessthan that of the lateral arms of thefeed slot, and means for transferring a rivet from the feed slot to the delivery slot.
2. Rivet feeding 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 T-shaped delivery slot beingofa uniform depth throughout a major portion of their lengtl'i, said depth being less than that of the lateral arms of the feed slot, and a reciprocatingslide for transferring a rivet from the feed slot to the delivery slot.
3. Rivet feeding mechanism including an inclined feedway havinga T-shaped feed slot formedtherein, a Tashaped delivery slot" offset from the feed slot,,the lateral arms of the T-shaped delivery slot being of a unifares for guiding the rivet heads to the shallow part of the delivery slot, and means for transferr ng a rivet from the feed slot to the delivery slot.
offset from the feed slot, the lateral arms of.
the T-sha-ped delivery slot being of a uniform depth throughout a major portion of their length, said depth being less than that of the lateral arms of the feed slot, the upper partof the delivery slot having inclined surfaces for guiding the rivet heads to the shallow part of the delivery slot, and a reeiproeating slide for transferring a rivet from the feed slot to the delivery slot.
In testimony whereof I afiix my signature.
EDWVIN B. STIMPSON.
