floor-CLAMP.

To all whom "it may concern:

Be it known that I, WILLIAM H. HOLMES, a citizen of the United States, residing at Proctor, in the county of Rutland and State of Vermont, have invented a new and useful Hoop-Clamp, of which the following is a specification.

This invention relates to coopering, and more especially to hoop clamps; and the object of the same is to produce a foot operated device adapted to simultaneously serve the dual function of a clamp for holding the lapping ends of the hoop and an anvil upon which the nails driven through said ends may be clenched. This object I accomplish by the construction hereinafter more fully described and claimed, and as shown in the drawings wherein Figure 1 is a front elevation of this machine complete. Fig. 2 is a central vertical section thereof. Fig. 3 is a plan view.

In the drawings the numeral 5 designates a standard having a base 6 at its lower end and a longitudinal slot or recess 7 in its upper end, and 8 is a foot lever pivoted at 9 to said standard and normally supported by a spring 10. The numeral 11 designates the face of a curved anvil, and 12 is its upright body connected with said face by several webs 13, the body being secured to the front face of the standard in any suitable means as by screws 14 and the curved face or anvil 11 projecting forward from said standard as best seen in Fig. 2. 15 designates a box for nails or the like, preferably having a hinged cover 16, the whole being attached to the front of the body of the anvil in convenient position for access by the operator. These parts constitute the fixed members of the clamp for holding the lapping ends of a hoop, and the face 11 is of a curvature corresponding with that of the hoop to be nailed.

The moving member of the clamp comprises a curved arm 21 having depending from it near its ends two guides 23 which slide behind the rear portion of the body 12 of the fixed member, and depending from its center and also behind said body 12 a bar 22 which has a foot 23 at its lower end, said foot being connected with the foot lever 8 by means of a link 24. Projecting forward from each end of the arm 21 and facing downward is a jaw 25 which extends over the anvil 11 and is normally supported above the same by means of the Specification of Letters Patent. 7 Patented Aug. 29, 191.1. Application filed February 11, 1911.

Serial No. 607,991.

spring 10. The fixed member and the movable member of the clamp may both be of metal, whereas other parts excepting the spr ng may be of wood or any desired mausual; and the size and shape and details of construction are matters of no moment in this invention.

In operation the hoop (not shown) has its ends brought together and lapped, and then laid upon the anvil ll beneath the jaws 25, after which by depressing the foot lever 8 the operator moves the movable member downward so that the jaws descend upon the ends of the hoop and press one upon the other and both downward onto the anvil where they are forcibly held. Thereafter, taking some nails from the box 15, he drives them downward through the uppermost hoop-end, then through the lowermost hoopend, and finally causes their points to impinge upon the anvil which turns them aside and clenches them into the inner face of the hoop as thehammer sinks their heads in the outer face thereof. After the lapping ends have thus been securely connected with each other, the operator releases pressure from the foot lever 8 and the spring 10 causes the movable member -of the clamp to rise so that the jaws 25 release the hoop, and the latter is free to be removed and replaced by another for a repetition of the act just described.

What is claimed as new is:

1. The herein described hoop clamp, the same comprising an upright standard having a recess in its face, a fixed member consisting of a body secured to the standard across said recess and a curved anvil projecting forward from said body, a movable member consisting of an arm, jaws projecting forward therefrom above said anvil, and a bar descending from the arm and slidably mounted in said recess, means for holding the movable member normally elevated, and a lever for overcoming said means and depressing the movable member when desired.

2. The herein described hoop clamp, the same comprising an upright standard having a recess in its face, a fixed member consisting of a body secured to the standard across said recess and a curved anvil projecting forward from said body, a movable member consisting of an arm, two jaws projecting forward therefrom above said anvil, and a bar descending from the arm and slidably mounted in said recess, a foot lever pivoted to said standard, a spring normally raising the lever, and a link connecting the foot lever with the lower end of the bar, the whole for use substantially as hereinbefore described.

3. In a hoop clamp, the combination with an upright standard having a recess in its front face, an arm slidably mounted in said recess and having a foot projecting forward from its lower end, a foot lever pivoted to the standard, means for normally raising said lever, and a link connecting the latter With said foot; of a fixed member including an upright body extending across said recess, a curved anvil projecting forward from the upper end of said body, and webs integrally connecting the latter with said anvil, and a movable member including a curved arm connected to the upper end of said bar and standing in a plane in rear of the body of said fixed member, guides depending from said arm and moving against the rear of said body, and jaws projecting forward from the ends of said arIn across the anvil and normally sustained above and out of contact with the same when said foot lever is elevated.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

WILLIAM H. HOLMES.
