a One object of this invention is to provide a rivet-making machine having arotary .dial for carrying a plurality of rivet blanks, the lower 'end of said dial being immersed in'ia tank of cooling liquid in .order to quench the .rivets between the heading and trimming operations.
A further object is to provide a single rivet-making machine of the above nature which will automatically perform the operations formerly done in two or more separate machines.
A further object is to provide a machine ofthis nature which will be relatively simple and inexpensive to manufacture, easy to 2" manipulate, very eflicient and durable in use, and which will occupy only a relatively small floor space. V
' With these 'and other objects in view,
there has been illustrated on the accompanythe invention may be conveniently embodied in practice.
'Fig. 1 represents a top' plan view ofthe machine. I o Fig. 2' is a transverse sectional view of the same, taken along the line 2-2 of Fig. 1, looking in the direction of the arrows.
Fig. 3 IS a front elevation of the machine with certain parts broken away., V

tary view of the machine, taken along the line 4-4 of Fig. 3,:looking in the direction of the arrows. Y
Referring nowto the drawings in which j likereference numerals denote corresponding parts throughout" the several views, the numeral 10 indicates the body member of the machine, said body member being preferably rectangular in shape and o n at its center for housing the. rivet-hol ing dial, punch-carrying gate, and, quenchin tank. The body member 10 is supported by legs 11 which rest. upon the floor of the room where the machine is to be operated.
In order to transmit power for operating the machine, provision is made of a pgilley 12 which is ada ted to receive a It, not shown, said pulley 12 bein mounted on a main shaft-13, which is a a ted to rotate 'in suitable bearings in the body member 10.
preferably circular in shapeprises an outer die The main shaft 13 is provided intermediate its length with an eccentric cam 14 upon which a reciprocating crank arm 15 is mounted, said crankarm 15 being pivoted at its other end upon a pin 16 carriedb a sliding gate member 17. The gate mem r 17 is mounted-to reciprocate withina pair of horizontal guideways 18 and 19, and carries at its free end a punch head 20, u n which are mounted a pair of spaced punc es comprising a heading punch 21 and a trim ming punch. 22, respectively.
Rivet-carrying dial. 7 Mounted adjacent the punch ,head and in-alineinent therewith is a rotary dial-.23 and carrying arranged tubular -Each pair of dies com- 24 and an inner die 25,
four pairs of radially rivet-holding dies.
said pairs being spaced degreesfrom each other.
The dial 23 is adapted to lie in flat contact with the inner face of the front of member 10, and is'fgeared to rotate in a clockwise direction, as viewed in Fig. 3. The dial 23 is given an intermittent oneway motion by means of a Geneva stop motion comprising a central member 26 having four spaced radial slots 27. The member 26 is mounted on the dialrshaft 26'." A pin 28 carriedon the outer end of an oval disc 29 is adapted 'to successively travel through the slots27 in such a manner that the jdml 23 will be-given a quarter. of a. revolution for i said disc 29.
The disc 2.9 is mounted on a shaft 30,
said shaft receiving. power indirectly from the pulley 12 through spun- gears 31, 32 and 33, shaft the body 34, bevel gears 35 and 36, and spur .each complete rotation .of I
smearin m m-tn; In order to deliver rivet blanks to the machine, a metal wire or red 39-is continually fed through a passage 40 in the front of the body member by means of feed rolls 53 and 54 to be described later. The passage gear 66 mounted carried by a rotat' 40 is located in alinement with one of the four sitions of the outer dies 24, said outer es serving to support the rivet wire '39 while said wire 39 is being cut off by a shearing member 41. The-shearing member 41 is mounted to slide in a transverse passageway 42, in the body member 10, and has a square cutting edge 43. The 8119813111 member 41 is provided near its outer end with a pair of oppositely disposed pins 45 on its upper and lower faces, said-pins 45 being disposed in a pair of alined circular cam slots 46 located-in a reciprocating head .47. The head '47 is connected by a pivot pin 48 to a pitman rod 49, the latter being pivoted at its other end 59 to a pin 51 eccentrically mounted on a disc 52, the letter being rigidly carried on the end of the main shaft 13.
Wire-feeding mechanism being actuated by a pawl member 60,- saidpawl member receiving an oscillating motion by a short pitman rod 61. The other end of the rod 61 is pivoted upon a pin 62 disc 63 mounted on the shaft 64 whic passes transversely through the body member 10. The shaft 64 on the end opposite from the disc 63 carries a bevel gear 65 which mesheswith a bevel on the shaft 32, previously mentioned.
Blank transfer y In order to transfer the blanks 44 from the outer dies 24 into alinement with the inne'r (118$ 25, provision is made of a fiddle :bow or lever 67 pivoted at 68 on a bracket 69 secured on the top of the body member 10 as by screws 69. The up fiddle how 68 is providedwith' an aperture through which a rod 70 is adapted to slide, said rod 7.0 being ivoted at 71 to said bracket 69. A spira tension spring 72 surrounds said rod 70 and serves to pre s the fiddle bow 68 continuously about it: pivot against the blank 44.
In the operation of the blank transfer mechanism, when the sheiu'ing member 41 is forced inwardly after cutting off the rivet blank from the wire 39, said blank will be carried to the left, asviewed in Figs. 1 and the machin r end of the 3, or to the right, as viewed in Fig. 2,-unt il it'comes into alinement with the inner die 25. When the gate member 17 next moves forward, the punch 21 will force the blank 44 into said inner die 25 and head. it. During the heading operation, it will be understood that the end of the rivet blank 44, not be headed, will rest upon the flat face of the dy member 10 wit which the dial 23 is in contact. a j 4 r Quenching apparama.
In orde'r to cool the rivet blanks 44 which are necessarily heated 'by the heading operation, provision .is made of a .narrow tank 73 covering the lower end "of the dial 23 and containing a suitable quantity cf cooling liquid'74, preferably a uenchmg 01L Thetank73hasaflan e75wededor tl1er-v 'wise secured to the y member 10, as clearly shown in Figs. 1, 2, and 4. 4
Trimming mechanism.
Rivet-ejecting mcizam'ana After a rivet-has been trimmed, the next indexing movement of the dial 23 will carry it to the uppermost position of the dial and into alinement with an ejecting or knockingout pin 76. The knocking-out pin is carried upon the forward end of a Z-shaped member 77 slidable in a bracket 78 secured upon the top of the bod member -10, as by bolts 7 8. The outer en of the Z-shaped member 77 is provided with a pin 78 idable in a slot 79 in a cam lever 80, said cam lever being pivoted on a pin 81 carried b a bracket 82, the latter bein secured to the ody member 10, as by a be t 82.
The lower end of the cam lever is provided with an offset ear 83 carrying a roller 84 adapted to continuously contact with an egg-shaped cam 85' rigidly mounted on the shaft 64. In order to keep the roller '84 pressed firmly against the cam 85 at' all.
times,
rovision'is made of as iral sprin 86, said if to'pins 8% spring being connects and 88 mounted on the cam lever 80 and.
the bottom of the body member 10, respectively.
In the operation of the ejecting mecha r" nism, the knock-out pin 76 will eject a rivet from the top of the dial each time thatthe latter is at rest, causing said rivets to drop into a suitable container or chute, not shown, whereby they may be removed frnri. D :1.
It will be understood that any suitable means may be provided for lubricating the successive operations of cutting-off, heading, and trimming. Preferably-the lubricant employed 'will be the quenching oil 74 lo-' cated in the tank 73, said lubricant being returned to said tank after it has performed its lubricating functions.
While in this particular embodiment of the invention, a belt-driven pulley 12 is shown for furnishin the powerto the machine, it'is to be un erstood that an electrically driven motor-may be substituted therefor within the spirit and scope of the invention. 7
One advantage of the present rivet-making machine .is that it will automatically perform the successive operations of-headmg, quenching, and trimming, thereby reducing to the minimum the expense of equipment, labor, and floor space.
It will also be understood that a pair of gate members may be used instead of the single gate member 17 herein illustrated, in which case one gate member will carry the heading punch, and the other gate member the trimming punch, and that said gate members will be driven by separate eccentrics mounted on the main shaft.
While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from'its spirit.
