To all whom it may concern f Be it knownthat I, ROBERT (W. RUTH, a

citizen of the United States, and resident of Belle Vernon, in the county of Fayette,

and Stateof Pennsylvania, have invented a new and useful Improvement in Swaging- Machines, and I do hereby declare the followin to be a full clear'and exact descri .2: a V 7 T eating dies, whose operation is attended with a great noise and severe yjarring action, which is not only nerve-racking to those 1n the vlcinity of such a machine, but is very severe on the wear and teardue to this jolti-ng and jarring action of-theparts. V t

In the accompanying drawings,Figure 1 is a plan view of my improved machine; Fig. 2 is a section on the line 2-2, Fig. 1; Fig. 3 is an end view; Fig. 4' is a longitudinal section of the w'abbler and the cross-head'; and Fig. 5 isasection on the line 55 Fig. a j i In the drawings, the numeral 2 designates a suitable bedplate in which the driving mechanism is mounted. A motor 3 has the pinion 4 on its armature shaft meshing with the gear-wheel 5 on the stub-shaft6 mounted in suitable bearings A suitablezclutch 8, keyed on theshaft 8, is operated bythe lever 9 for moving said clutch into and out of engagement with the stub-shaft .6.

The counter-shaft 1 0 is driven by the worm 11, 'onlthe shaft 8?, meshingwiththe w0r1n-wheell2 mounted on said shaft 10. The shaft 10 is mounted in suitable bearings13..-

Mounted on the shaft 10is the cam-disks 14 with cams 15 formed on its periphery. The cams l5 gradually increase in size, reaching a maximum at 16 to provide for the gradually increased movementa-of the swaging dies, as more. fully hereinafter set forth.

The periphery of the cam-disk 14 engages the idle roller 17 mounted on the rocker-arm 18 which is pivoted at 19 to the support 20. This rocker-arm18 has the seat 21 to receive the wabbler 22.

Application filed January 17, 19 18. Serial No. 212,183.

This wabbler 22 fits in the recess 23 formed in the end of the plunger portion 24 of the cross-head 25. Ths cross-head 25 is of the spider form having four arms, which arms pass through openings 26 formed in the guide-frame 27. The guide-frame 27 has the flange 28, the bolts 29 passing through said flange are connected to the bearings 13. The opposite end of said guideframe 27 is connected by the bolts 30 to the stationary frame 31. In this manner, the guide-frame 27 is securely held in place and acts asa guide for the cross-head 25 and the plunger portion 24.

l The cross-head 25 is connected up by bolts 32 to the togglering 33.

Mounted on the bolts 32 and interposed between the cross-head 25 and the stationary frame 31 are the springs 34.

The guide-rods 35 connect the stationary frame 31 with the stationary-frame 36 and said guide-rods pass through openings in the toggle-ring 33, and form guides for said tog gle-ring' as it moves back and forth in the manner more fully hereinafter set forth.

The toggle-ring 33 has the blocks 37 fitting in seats 38 and held in place by the bolts 39. Adjusting screws 40 are provided for adjusting the position of the blocks 37. These blocks 37 are arranged radially around the toggle-ring 33, and toggles 41 fit into seats 42 in said blocks 37, and the other ends of said toggle engage seats 43 in the swaging-jaws44. V

These jaws 44 are pivoted at their inner ends by the pins 45 to the brackets 46 secured to the stationary frame 31 by bolts 47. Adj usting screws 48 are provided for adjusting the position of the brackets 46.

Springs 49 on the bolts 50 are interposed between thenuts 51 on said bolts and the brackets 46, the inner ends of said bolts being secured into the 'swagingijaws 44. These springs act to return the jaws to normal position after they havebeen advanced in the swaging operation.

Suitable swaging-dies 52 are bolted or otherwise secured to the swaging-jaws 44, said swaging-dies varying in shape accord ing to the shape to be given to the article to be swaged.

The operation of my improved swaging machine is as follows:

Rotary movement is imparted to the cam disk 14 by throwing the clutch 8 into driving engagement with the power-shaft, and

as said cam-disk rotates, the cams 15 engage in succession the roller 17 and through the rocker-arm 18 impart a longitudinal movement to the cross-head 25 and likewise to the toggle-ring 33 connected thereto. The Y article to be swaged, having been properly heated,and let it be supposed that in this case the article consists of a short tubular section which is to be swaged by the dies 52,i-is inserted between the dies, andas the toggle-ring 33 is advanced by the; movement of thecross-head 25, the toggles d1 acting on the swaging-jaws 44 will move said aws inwardly and the swaging dies will be forced against the articleheld in position therein. As stated above, the cams 15. of the camdisk 14 gradually increasein size so that the inward movement of the swaging-jaws is slightly greater each time said toggle-ring advances, and the swaging action takes place gradually by a squeezing or apressing action until-the maximum cam 16 engages the roller 17 and the greatest movement is imparted to the swaging-rjaws whenthe swaging action is completed. 7 T o 'By this means for causing successively progressive radial movement to the dies, the swaging is accomplished by a gradual squeezing or pressing action, and the swa ing takes place without the awful din and clatter which is present in the swaging inachines ordinarily' employed where-there is a quick reciprocating action of the swagingdies and furthermore, by my improved ma-. chine, wear and tear on the parts is reduced to a minimumdue to the fact that there is none of the chattering or racking action such as is present in machines of thejrecip rocating type.

It will be apparent that the adjustments may be quickly made for taking care of. different sized articles to be swvaged for the amount of swaging to be donejto any article, and that the dies may be readily changed to impart diiferent sizes, shapes ortapers to the articles tobe swaged.

What I claim is: i

of radially-arranged movable swaging-dies,
