UNITED STATES WILLIAM EDWARD BEDELL, or MONTPELIER, IDAHO.

' ANVIL.

Application filed March 22, 1921. Serial No. 454,581.

To all w hom it may cof/wem:

Be it known that I, W'ILLIAM EDWARD BEDELL, a citizen ofthe United States, and a resident of Montpelier, in the county of Bear Lake and State of Idaho, have invented a new and Improved Anvil, of which the following is a full, clear., and exact description.

This invention relates to a work-supporting anvil, and has particular reference to anl anvil for supporting ring gears which are'to be riveted to a gear plate.

An object of the invention is to provide a simple and efficient clamping means cooperating with a new and improved anvil whereby the work may be very readily fastened to the supporting plate. y

Anothenobject resides in the provision of a simple, rugged and easily operated gripping means.

A further object resides inthe particular construction, and arrangement of parts which are hereinafter described and shown in the accompanying drawings. A

The invention is shown in the drawings, of whichy Figure 1 is a vertical section taken through the anvil showing the gripping means in side elevation Figure 2 is an elevation looking at the side of the gripping means; and

Figure 3 is a plan view.

The preferred form of my invention, as shown in the drawings, embodies a base portion 1 to which a hollow cylindrical clamp or pedestal 2 is connected. The pedestal at its upper end is provided with an annular flange portion 3 which, with the upper end of the pedestal 2, forms an upper supporting surface for the work to be placed thereon. The pedestal is provided with a bore or aperture 4t adapted to receive centrally protruding parts of any work which may be placed thereon. Beneath the ange 3 and on opposite sides of the pedestal 2 near its upper end are a pair of spaced bearing lugs 5 and 6 adapted to receive therebetween a pivoted actuating member 7. Each oi these actuating members, at its lower end, is provided with a handle portion 8. To a pin 9 on each actuating member is pivoted a lug member 9. This lug member 9 extends upwardly in the form of a connecting rod 10 around the outer edges of the iange portion 3 to a horizontally extending portion 11. The end of this horizontally extending portion 11 is pierced by a suitable aperture and adapted to embrace a rod 12. The lower surface of the outer end of the horizontally extending portion 11bears against a plate 13.. The lower end of the rod 12 is provided with a plate 1/1 attached thereto. Between the plates 13 and la a spring member 15 extends. The lower end of the rod 12 is shaped in the form of a head 16 which is adapted to bear against a plate 17 to which a portion of a ring gear 17 is adapted to be riveted. -When these actuating members are moved to the position shown in the figures, the points of connection between the rod 10 and the members and the pivot points of the members to the lugs 6 are so related that the connecting points lie within the vertical line drawn through the pivot points and, consequently, these actuating members will be held in their closed position.

The upper end of the right-hand rod 12, shown in Figure 1, is supplied with a collar 18 having spaced ear portions projecting therefrom. Between the ear portions a pin 19 extends. On the left-hand rod 12, shown in Fig. 1, a similar collar 21 is placed. To `this collar is pivoted a connecting rod or link 2O provided at its outer end portion with a hook 20 adapted to engage with the pin 19 above mentioned.

Vhen a ring gear is to be suitably riveted to its operating plate, such as 17, it is placed in the proper relative position and then disposed on top of the anvil, as shown in the drawings. The lower ends or heads 16 of the rods 412 are then placed, as shown, against the upper surface of the plate 17 on opposite sides thereof. The connecting rods or links 10 and 11 extend around the flange portions 3 to the handles 8. These handles normally are raised to permit a free movement vertically of the rod 12. lVhen these handles 8, however, are moved into the position shown in Fig. 1, the connecting links 10 and 11 are turned down against the plate 13, which is free to slide on the rod 12, and causes the spring 15 to be depressed and exert its force against the plate l-L and therethrough to the head 16 of the rod 12. The connecting link 20 is fastened across in the position shown in full lines in Fig. 1 to maintain the upper ends of the rods 12 in the proper spaced relation so that they cannot shift after the device is clamped on to theplate 17.

It is, therefore observed that I have provided a simple, compact, rugged, rigid and easily operable clamping device attached to an anvil of unique construction whereby work-pieces may be very quickly and readily and iirmly supported on an anvil to be treated in one manner or another'.

lVhat I claim is: v

1. An anvil or supporting plate for Workpieces, which comprises a supporting plate, a pair ot spring-pressed clamping members adapted to be disposed on opposite sides of the supporting plate, adjusting means, con nections between the clamping members and the adjusting means whereby the clamping members are moved to operative position, and spacing means adapted to hold the clamping members in a deinite relation after .they have been moved into operative position.

Q. A clamping device tor anvils having a supporting surface, which comprises a clamping rod having an enlarged head portion thereon, a plate slidable on the rod, a spring member disposed between the head and the plate, .an actuating member, and connections between the actuating member `and the movable plate whereby the movement oi the actuating member will cause the movement oit the clamping member through the spring.

3. An anvil comprising a. supporting surface, a pair ot clamping members disposed K in relative positions on opposite sides of said surface, each of said clamping members having an enlarged head portion, a plate slidable on each o't said clamping members, a spring disposed between the sliding plate and the head portion, an actuating means for each clamping member, connections between the actuating means and the movable plate whereby the clamping member is moved to l operative position by the movement of the actuating means, and a rigid spacing member connectingy the upper ends of the clamping members to hold them in proper spaced relation when in their clamping position.

Li; A. clampingimember for holding Workpieces on supportinoplates, which comprises a clamping rod having a flanged head thereon, a. coil spring disposed around the clamping` rod, one end of the spring bearing against the flanged head, a movable plate bearing against the other end of said spring, a connecting' rod embracing the clamping rod and bearing against the movable plate, and an actuator pivoted to the supporting plate, the other end of the connection being pivoted to the actuator. Y

5. A clamping member for holding Workpieces on supporting plates, vwhich comprises a clamping rod adapted to be disposed above the sup-porting plate, a pivoted actuating member disposed below the plate and having a iixed pivot point, a pivoted connection between the rod and actuating member, said connection when the member is in its closed or normal position lying Within the vertical line drawn through the fixed pivot so that the actuating member tends to remain in this closed position until forcibly removed therefrom.
