Patented June 17, 1930 UNITED STATES mann 'ran- J'OI-IN G. HANNA AND .ADOLF NORIN, CHIGAGO, ILLINOIS, .ASSIG'NQRS TO I-IANNA ENGINEERING WORKS, GF CHIGAGO, ILLINOIS, CORPORATON OF ILLINOIS I' 'runnnr nIvn'rEn Application filed. August 10,` 1925. Serial No. 49,374.v

vwith a plurality of fixed 'dies .which may be selectivelyr brought into registration with the movablex dies. This type of machine is used largely in connection with work such as the formation of automobileframes, each unit of which requires a number of riveting operations, the rivets varying in length.

It is an object oflthe present invention to provide a riveter of this character having aplurality of rapidly interchangeable fixed dies. I I

It is a further object to provide such a riveter in which the fiXed dies are simple in design and construction and capable of ready removal and replacement upon the machine rwhen necessary. vIt is an additional object to provide a construction in which the fixed dies may be moved from the cylinder side of the machine.

It is also an object to provide a structure which is simple; in design and construction and adapted forcommercial production and rapid Operation. v

Other and further objects Will appear as the description proeeeds. i

We have illustrated a prefer-red embodi- `ment of our invention in the accompanying drawings, in which I Figure l is a side elevation of the machine; Figure 2 is a view of Figure 1 as seen from the left; v i v Figure 3 isr a view on anenlarged scale partly in section showing th'efixed die rotating and locking mechanism, and

Figurer4 is a fragmentary view showing the method of securing the fixed die supporting members tothe turretihead.

Referring first to Figure 1, the riveter comprises the main frame 11 having the turret receiving barrel 12 and the operating plunger support l13. The operating .lever 14 is provided with extensions 15 which are journaled upon the shaft 16. This shaft 16 is supported in the frame extension 13. The lower end of the operating lever 14 is connected by pin 17 with the piston rod 18,

which is operated by the 'piston cylinder 19. The oylinder 19 is supported upon the pin 20 carried in the extension 21 of the main frame 11. The method of operating the pistonin cylinder 19 forms no part of the present invention and has not been disclosed in detail.

The operating lever 14 is connected by links 22 with the plunger 23 Which operates through the frame portion 13. The plunger 23 carries the movable die 24.r xThe fixed dies 25 are carried by the extensions 26, which as bestshown in Figure 4, are detachably securedw to the turret head 27 by the bolts 28. These members 26 also bear against the large shoulder 29 on the outer end of the turret 27. I

The turret has the cylindrical extension 30, as best shown in Figure 3,, which eXtends through the barrel 12 of the main frame. The rod 31 extends outwardly from the end of the turret member and the collar 32 is rotatably fitted upon the rod 31 and retained in place by the nut 33. The control handle 34 is pivotally supported `rupon the collar 32 and carries the plunger 35 Which is pressed outwardly by spring 36 against the lug 37'whichv extends fromV the collar 32. The handle 34 is provided with the lug 38 which is adapted to engage in the notch 39 in the flange 40. This flange 40 is secured. to the barrel 12 by bolts 41, as best shown in Figure 3. The handle 34 is also provided With the deeper lug 42 which is adapted to engage any oneofthe notches 43 fornied in the end of the turret member.

In the Operation of-the riveter, the movable plunger 23 and movable die 24 are reciprocated by admitting a compressedfiuid selectively upon the opposite sides of the piston carried in cylinder 19. This serves to rock the operating lever about the shaft 16 and perform the riveting Operation. The turret head is shown as provided [with four members 27 carrying fixed dies 25 of different heights which are thus adapted to cooperate with the movable die to drive rivets of different length.

The turret is looked with any desired fiXed die in registration with the movable die Vby the engagement of the lugs 38 and 42 with the notch 39 and a registering notch 43. To move the next ixed die into registration with the movable die, the handle 34 is swung outwardly against the lug 37, the spring 36 being compressed and is then swung in the counter-clockwise direction to the position shown in Figure 2. During this movement, the lug 42 will be riding on the end of theturret member and when'it reaches the next notch 43 will be dropped down into that notch by the power of the spring 36. The lug 38 will now rlde on the flange 40. The handle is next ro-r tated in the clockwise direction until the ment of our invention in the accompanying drawings by Way of illustration only, and We contemplate such changes and modifications as come within the spirit and scope of the accompanying claims.
