EDWIN E. GREAVES, OF SYRACUSE, NEW YORK, ASSIGNOR T0 CROUSE-HINDS COMPANY, 0F SYRACUSE, NEW YORK, A. CORPORATION OF NEW YORK.

FASTENER FOR BOXES.

Application filed July 23, 1915.

To (LZZ whom, t may concern.'

Be it known that I, EDWIN E. GREAVES, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Fastener for Boxes, of which the following is a specification.

This invention has for its object a simple and efficient clamping means for securing two parts together, particularly adapted to secure a cover to a box, and more especially adapted to secure the trim of a panel board cabinet to the box or cabinet; and the invention consists in the novel features of construction hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings, in which like characters designate parts in all the views.

Figure 1 is a plan view, partly in section, of a portion of a panel board cabinet embodying my invention, the trim bein removed but the position thereof being indicated in dotted lines.

Fig. 2 is a vertical sectional view on line A-A, Fig. l.

Fig. 3 is an elevation of parts seen in Fig. 2.

Fig. 4 is an elevation of parts seen in Fig. 3 looking to the left.

1 designates the side walls of a panel board cabinet, and 2 the trim, these parts corre sponding to the sides and cover of a box or cabinet, or to any two parts to be clamped together.

The side walls 1 are shown as formed with inturned flanges 3 at their to s upon which rests the cover or trim 2. he clamping means is here shown as carried by the cover or trim 2 and includes a jaw movable under and out from under the flange 3 about an axis and movable rectilinearly toward and from the flange, an operating part carried by the cover to move the jaw rectilinearly and about an axis durin one continuous operation of said part, and means for guiding the jaw during its movement.

4 designates the jaw which is in the form of an elongated nut havin a threaded passage nearer one end than t e other, and 5 is the operating means which is a screw extending through the trim 2 and through the threaded passage, of the nut 4, the screw bein normally held from endwise movement re atively to the cover or trim 2. The guid- Specieation of Letters Patent.

Serial No. 41,547.

ing means by which the nut is moved by the screw rectilinearly to-ward and from the flange 3 and about the axis of the screw when disengaged from the flange 3 by merely turning the screw in the ordinary manner without any additional manipulation, comprises a guide 6 carried by the trim 2 and having a guide-way in the form of an angular slot having a portion or arm 7 extending lengthwise 0f the guide 6 parallel to the screw, and another portion or arm 8 extending about the axis of the screw or parallel to the thread, that is, the portion 8 is of the same incline as the thread.

The guide 6 is also formed with laterally extending ears 9 which may be secured to the cover-2 in any suitable manner, as by rivetin or spot welding.

A suitable shoulder 10 is provided on the nut, which shoulder extends through the angular slot. As here shown, this shoulder 10 is a screw extending through the angulaislot in the guide 6 and into the nut, the head thereof engaging the outer face of the guide.` This guide is shown as having an inner arcshaped face 11 concentric with the axis of the screw, and also with an arc-shaped outer face, and the nut is shown as formed with an end face 12 concentric with the screw, the face 12 engaging the face 11 of the guideway.

Said face 12 includes a cylindrical portion concentric with the screw and a conoidal portion beveled off' at 13 on the upper side of said face in the direction of movement of the clamp into operative position, that is,

upwardly toward the upper side of the jaw or nut. When the screw is being turned to clamp, the jaw naturally stands at an ineline, with the end of the jaw on which the working face is located elevated above the opposite end of the jaw. The beveled portion13 of the jaw permits the screw to stand in this manner thus avoiding binding of the jaw on the guide 6. working face of the jaw engages the art to be clamped, as Vthe flange 3, continued turning movement of the screw causes the screw to assume a vertical position, and the jaw a horizontal position and the jaw to brace 105 against the guide 6 with the cylindrical portion of its end face engaged with the inner cylindrical face 11 of the guide.

Preferably, the workin face of the jaw is raised as at 14.

However, when the Hence, t ie jaw has a bearing on opposite sides of the screw, which feature is advantageous as the screw is oii'- set from the working face and the force of the screw is applied to the nut at a point remote from where the nut engages the flange 3. The screw is held from endwise movement so that the turning of the screw will effect an endwise movement of the jaw or nut et by any suitable means, andas here shown said means is a compression spring 15 interposed between the cover or trim 2 and the nut, the spring having an arm 16 at its lower end which rests in a seat 17 in the upper face of the' nut or jaw 4.

In operation, the clamping means is applied to the cover or trim, and the cover or trim placed in position on the flanges of the side walls of the box. By a mere turning movement of the screw, owing to the angular slot, the nut or jaw -1- is first turned so that it is under the flange 3, and continued turning movement of the screw without any attention being given to the nut by the operator, moves the nut into clamping position, and when it is desired to remove the cover, a simple unscrewing operation of the screw will first move the nut endwise until the shoulder 10 passes out of the lengthwise portion 7 of the angular slot and then the nutwill turn about its axis out from under the flange 3 owing to the transverse arm or portion 8 of the angular slot.

What I claim is z*- 1. A clamp comprising a non-endwisely movable screw, a jaw threading on the screw, and a guide having an angular guidcway extending parallel to the screw and about the axis of the screw, the aw having means engaging the guideway, substantially as and for the purpose specified.

2. The combination of two parts to be clamped together, and a clamp comprising a screw extending through one of said parts, a jaw into which the screw threads, movable into engagement with the other of said parts, and a guide carried by the former part and formed with an angular guideway, one portion of which extends parallel to the screw and another portion of which extends in a direction about the axis of the screw, the jaw having meansengaging the guide, substantially as and for the purpose set forth.

3. The combination of two parts to be clamped together, and a clamp comprising a screw extending through one of the parts, a jaw into which the screw threads, movable into engagement with the other of said parts, a guide carried by the former part and formed with an angular guideway, one por tion of which extends parallel to the screw, and another portion extends about the axis of the screw, the jaw having means engaging the guide, and a spring acting to hold the screw from endwise'movement, substantially as and for the purpose described.

4. The combination of two parts to be clamped together, and a clamp comprising a screw extending through one of said parts, a nut on the screw movable thereby into engagement with the other of said parts,

means for holding the screw from endwise movement, and means for holding the nut from rotation during a part of the turning of the screw, and permitting the nut to turn with the screw during another part of the turning movement of the screw, substantially as and for the purpose speciiied.
