ADJUSTABLE SAFETY-HANDLE.

Specification of Letters Patent.

Patented Feb. 17, 1914:.

Application filed May 16, 1913. Serial No. 767,973.

' proper in position, and firmly retaining it therein, and adapting the same to be removed from said object so that the carrying of the latter by an unauthorized person is rendered inconvenient, other details being presented as will be hereinafter described and claimed.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.

Figure 1 represents a perspective view of a handle embodying my invention. Fig. 2 represents a longitudinal vertical section thereof. Fig. 3 represents a top or plan view of a port-ion thereof. Fig. 4 represents a vertical sect-ion on line :cw Fig. 2. Fig. 5 represents a top or plan view of a portion of the handle proper of the device. Fig. 6 represents a top or plan view of a portion of the top plate of the device. Fig. 7 represents a perspective view of one of the end arms of the handle proper. Fig. 8 represents a vertical section of a portion on line g/ g/ Fig. 2. Fig. 9 represents a perspective view of a portion of the handle proper 0pposite to Fig. 7. Fig. 10 represents a perspective view of a portion of a lever employed in the device. Fig. 11 represents a vertical section of a portion of the handle proper, the top plate, said lever and a stud employed. Fig. 12 represents a section of a portion showing a reinforce or stiffener for the top plate of the device.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates the top plate of the device, the same being attachable to an article to be carried, for instance, a suit-case, satchel, etc. 2 designates a handle, which is adapted to be connected with said plate above the same by means as follows On the side of the depending arm 8 of the grip of the handle, said arm being flat in cross section, are the recesses 4, and in the plate 1 is an opening 5 which narrower in one diameter than the other. On the plate above said opening is the rotating escutcheon or seat 6 which is retained within the collar 7, the latter being screwed or otherwise fastened to said plate, said seat having therein an elongated slot 8 which is adapted to register with the opening 5 in the plate 1, consequently when the lower end of the limb 3 is inserted in said slot 8, and the opening 5 in the long diameter of the latter, the handle is rotated a quarterturn, whereby the walls of the recesses 4: oc-- cupy a position at a right angle to that they occupied when the limb 3 was first inserted in said opening 5, consequently said walls engage the side walls of the narrow diameter of said opening 5 on the underside of the plate 1, whereby said limb is interlocked with said plate from below. The other depending arm 9 of the grip of the handle has a laterally extending flange 10 which is adapted to rest on the plate 1 and engage with the upwardly extending limb 11 of the lever 12, which is mounted on and depends from the underside of the plate 1 by the pivot 13, it being noticed that said plate has an opening 14 therein for the protrusion of the limb 11 therethrough, it being noticed also that the flange 10 has in the slot 15 to receive the limb 11 of the lever 12, an offset 15 which is adapted to receive the stud 16 which is secured to the plate 1 and rises therefrom, said offset being closed on its outer side by the wall 16 which serves to prevent subsequent disengagement of the handle from said stud.

In the side of the limb 11 of the lever 12 is the slot 17 whose wallis adapted to receive the portion of the flange 10 back of the slot 15 whereby said flange may interlock with said limb to prevent the handle from upward disconnection from the limb 11, it being seen also in Figs. 3, 2, and 11, that the stud 16 enters the offset of the slot 14 and so controls the flange 10 that the latter is prevented from lateral disconnection from the limb 11 whereby the handle remains interlocked with the lever 12 and consequently with the plate 1. In order to operate said lever whereby its limb 11 occupies its elevated position in the opening 14: the upper side of its heel end has thereon an inclined plane or cam 18 which is adapted to be engaged by the lower end of the arm 3 of the handle and thus depress said end as will be hereinafter more fully explained while the lever may be operated to lower said limb 11 by the action of the spring 19 which is secured to the underside of the plate 1 and bears dowi'iwardly against said lever, as inc-st plainly shown in Fig. 2, it being noticed that said inclined plane serves to press the walls of the recesses 4 in the arm 3 tightly against the underside of the plate 1, while the relative portion of said arm occupies the opening 5. It will be seen that when the arm 3 is inserted in theseat or escutcheon 6 to full extent and then rotated, a quarter turn, its lower end rides on the inclined plane 18 and depresses the latter and with it the heel end of the lever 12. This raises the opposite end. of the lever and with it the limb 11, the latter then rising through the slot l l so as to be in the path of the flange 10 of the arm 9 when the handle has about completed its turn, and it is pushed forward sufficiently to cause the stud 16 to enter the offset 15 while the flange 1O enters the slot 17 of the limb 11, whereby when said limb has risen to full extent with the lever said flange and limb are interlocked and the handle is connected with the plate 1 and prevented from rising and lateral motions or disconnection.

It is evident that the handle may be removed by forcibly pushing it rearwardly and turning it in reversed direction to the first named, when the flange clears the stud 16 and the wall of the slot 15 withdraws from the slot 17 of the limb 11. Then the inclined plane 18 moves from the lower enl of the arm 3 thus relieving said end of the upper pressure of said plane, when as said arm completes its turn it may be drawn through the long diameter of the opening 5 and the slot in the escutcheon and so entirely removed from the plate 1, leaving the ol ject to be carried without the handle proper for a purpose hereinbefore stated. As the lower end of the arm 3 rides on the inclined plane, the latter rises with the end of the lever due to the action of the spring 19 when the limb 11 of said lever is lowered and s0 occupies a position below the top of the plate 1 whereby it is comparatively inacces sible.

The lever 12 may be guided in its motions by means of the inverted T piece 20 whose shank depends from the underside of the plate 1 and freely enters an opening 21 in said lever, the head of said piece being on the underside of the lever, so as to act as a stop limiting the descent of the same.

The mechanism of the device below the plate 1 is inclosed in the casing 22 for protection thereof against tampering and contact of the fingers therewith.

To the top plate 1 on the underside thereof, I secure the reinforcing member 24, see Fig. 12, which consisting of a strip of metal or other suitable material may be extended the entire or partial length of said plate, so as to strengthen the same, it being seen that said member has an opening for the passage of the limb 11 of the lever 12 there through, and that the casing 22 is connected with said member and the material of the object to which the handle is applied, is interposed between said member and plate and clamped thereby.

The recesses 4t in the arm 3 of the handle may be varied to change the combination employed for locking said arm with the plate 1 on the underside of the opening 5 therein. To accomplish this result, I employ the collar 23 which depends from the plate 1 about said opening In this case, should the handle be lost or stolen, said collar is provided with a plurality of openings 24*, one below the other in the side thereof, so that any kind of a pin may be passed thcrethrough, as shown dotted in Fig. 7. Then, a recess such as t will be filed or cut out in the side of the arm 3, of a new handle to be employed, below what is shown in said Fig. 7, so that said pin may be passed therethrough, this providing as it were, a locking combination for said new arm independent of the plate 1.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is z 1. A handle, a support, means on said support and handle whereby said handle is removably attachable to said support, said handle having a member mounted for partial rotation, and depressible means actuated by such rotation to lock the handle to the support.
