IMPLEMENT-CLAMP.

Speccation of Letters Patent.

Patented May 7, 1912.

Application filed February 8, 1910. Serial No. 542,797.

To all whom t may concern:

Be it known that I, SIMEON C. LAwLoR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Implement-Clamps;A

and I do hereby declare the following to be a full, clear, and exactdescription ofthe 1nvention, such as will enable others skilled 1n the art to which it appertains to make and use the same.

This invention relates to improvements 1n implement clamps, and the object in view is the increasing of the utility and efficiency thereof.

lilith this and further objects in view as will in part become obvious andV in part be herein stated, the invention comprises certain novel constructions, combinations and arrangements of parts as hereinafter set forth and claimed.

In the accompanying drawing,-Il`igur e 1 is perspective view of a clamp embodying the features of the present invent-ion. Fig. Q is a longitudinal, vertical section therethrough taken on the plane indicated by line 2, 2 of Fig. 1. Fig. 3 is a fragmentary, detail sectional view illustrating a modified embodiment.

In the accompanying drawing, 1 indicates the handle which may be of the ordinary type, and which is surrounded and engaged by the sleeve 2. A clamping jaw 3 is carried by sleeve 2, and a complemental clamping jaw 4 is pivoted to sleeve 2, as at 5, at the inner terminus of jaw 3. J aw 3 is apertured, as at 6, for the passage of a clamping bolt 7 which extends through a corresponding aperture in jaw 4 and is provided with t-he usual wing nut 8 below jaw 4, adapted to be manipulated for forcing jaw 4 into clamping relation with respect to jaw 3. The material of jaw 3 has a small portion contiguous aperture 6 stamped outwardly,

.forminga lug 9, which, after bolt 7 has been positioned, is bent down over the head of the bolt for preventing the bolt from being accidentally detached from the clamp when nut 8 is removed.

The jaws 3 and 4 are, of course, adapted for grasping any implement, but to facilitate the grasping of a mop, or like device, I provide a clasp which comprises a pair of rod aws 10, 10, pivotally connected together and having one IOd at each Side 0f Sleeve 2 projecting into the pivot opening of jaw 4,

the pivotal connection of jaws 10 being coaxial wit-h that of jaws 3 and 4. The outer edge of each of jaws 3 and 4 is formed with a bent or turned portion 11 within the inner corner of which the cross rod of the respective jaw 10 lies, and said jaw may be retained therein by various attaching means, but preferably by projecting tabs 12 extending from the respective jaw 3 or 4 and formed integral therewith and bent about the given rod. Obviously, the rod may be otherwise connected, as for instance as seen in Fig. 3 wherein the rod is retained by rivets 13.

In clasping a brush or other like implement it is frequently desirable to cause the jaws 10 to grasp one portion of the implement and to utilize auxiliary means for grasping another portion thereof. As such auxiliary clasping means I provide a hook 14, preferably formed of wire, with the free ends extending into and pivotally engaging a pair of apertures 15 in the rear portion of jaw 3 or the front end of sleeve 2, A series of sets of apertures 15 is provided for allowing the hook 14 to be adjusted along the aw 3 for accommodating various sizes of articles to be clasped. Obviously, as many sets of apertures 15 may be provided and may extend as far along the socket or sleeve 2 as may be found useful. Intermediate the length of hook 14 the wire arms which comprise the hook are dellected or bent downwardly, as at 16, 16, for offering a support for the hook when free from engagement with an implement, thus preventing the hook from ever falling down in front of the clamping jaws. The outer ends of the arms comprising the hook 14 are spaced such distance apart as will allow them to spring past the sides of handle 1 when the hook is swung to the dotted position seen in Fig. 2, said ends when in such position clasping the handle sufficiently for retaining the hook in the out-of-the-way position.

Contiguous the pivots of the arms which extend from and carry the clasping mem. bers of clasp 10, saidarms are slidingly surrounded by gripping links or rings 17, 1 7, which are adapted to be shifted along the arms away from the pivot point for producing or retaining a gripping acti-on of clasp members 10, and for insuring a gripping action of the portions of the clasp outside the main clamp. Also, when it is found desirable to omit bolt 7 to enable introducing the clamp in close quarters, the gripping rings 17 retain all clamping parts in gripping condition, and may be causedto release the same merely by sliding the rings 17 toward the pivots of the arms of clasp l0.

What I claim is l. In apparatus of the class combination with a pair of pivotally connected clamping jaws of a pair of rod jaws secured to said clamping jaws, respectively, along the clamping lines thereof, extending laterally beyond the same, and pivotally connected in the axial line of the clamping jaw pivot.

2. In apparatus of the class described, the combination with a pair of co-acting clamping jaws, of a pair of broader rod jaws having their clamping portions fixed to and substantially coinciding centrally with the corresponding portions, respectively, of the clamping jaws, the rearwardly and inwardly extending portions described, the

of one rod jaw forming two alining pivots for the compani-on jaw and said clamping jaws.

3. The combination with a handle member having a rigid projecting jaw with a broad clamping terminal margin, of a movable clamping jaw having a. like and co-acting margin, a pair of broader rod aws each having its terminal portion alining with and ixed to the corresponding portion of one of said clamping jaws, one of the rod jaws having its ends passed through said movable jaw into said rigid jaw and the other pivotally connected to its companion at substantially its point of entrance into said movable jaw, and rings sliding, respectively, upon the adjacent, slightly divergent rearwardly extending portions of the two rod jaws, substantially as set forth.

In testimony whereof I aiix my signature in presence of two witnesses.

SIMEON C. LAVVLOR.
