RIVETING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 716,156, dated December 16, 1902. Application filed January 28, 1902. Serial No, 91,551. (No model.)

` To a/ZZ whom t may concern.-

Beit known that I, WILLIAM JAMES WHA- LEN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Riveting-Ma'- chiues, of which improvement the following y is a specification.

plan view of the same in This invention relates to new and useful improvements iu portable riveting-machines.V

The object of my invention is to` provide a;

simple and practical apparatus ofA the above character adapted to be operated by hand and which can be manufactured and retailed at comparatively small' cost.

In the accompanying drawings I have illustrated the :apparatus in various ways, i whichi Figure 1 is'a longitudinalside View of the apparatus complete. Fig. 2 is a longitudinalV side view ofthe same in section. Fig. 3 isa section' along the line 3 3 of Fig. 2. g

Referring to said drawings for a description of the detail parts of my invention and their operative arrangement, the numeral 1 designates a casing having the chamber 2 at one end and a block 3 secured within the other end, which block is provided with a handle 4.- Loosely fitted into said chamber 2 is the header-die 5,having the concaved recess 5l in its face.` This die is secured in operativeposi# tion by a rod 6,Which extends across the `chamber through a `longitudinal opening 6in the rear portion thereof. YA pair of reciprocating plungers 7 are fitted .between'the casing or chamber walls and a lug 8. These plungersareprovided with heads 9 for alternate engage-Y mentwith said die 5 and at theirrear ends with rounded Shanks 10, which extend into. openings 1l in said block 3. These plungers shaft 14, having rigidly secured thereto the square cams 15 to engage with upward eXtensions 13 on said plungers. These cams are set at an angle of forty-five degrees from one another, so that when they are revolved one plunger will be held in forcible position after the other has spent its force upon the die. To rotate said cams, I secure to the side of the casing a gear-wheel 17 to mesh with a wheel 16 on the cam-shaft and provide the former with a handcrank 1S. The relative proportion between these wheels may be varied for increasing power and increasing or decreasing the rotation of the cams.

In Vpractice the device is grasped in one hand by the handle 4E. The die is then brought intoengagement with the rivet, and by` .a rotary' movement of thecrank with the other hand an alternate reciprocating movement is given to the plungers through the medium of the cams, which plungers, forciblyacting upon the die, will successfully head the rivet in a short time and with an expenditure of 'little force upon the part of the operator.

carriedby said plungers, an apertured block `carrying a handle andureceiqving said Shanks of the plunge'rs,.upward extensionsv carried `bythe plungers with a com monshaft mounted in the casing and carrying cams for engagement with said extensions, and means for operating said shaft,` substantially as described. t

InV testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses. A
