HAND-STRAP.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed May 13, 1909. Serial No. 495,734.

'My. inventionrelates to .hand straps and particularly to that class of devices em- 'ployed onst-reet railway or other cars to be sengers for support.

The object of the invention is to provide a hand strap on grip device of the character referred to which is simple in construction and arrangement and clean-and sanitary in use.

A further object is to provide a hand strap or grip device which, in use, affords a support free from swinging movement in the direction of the length of the car.

A further object is to provide a hand strap or grip device which, when not in use isretained in a normally retracted position.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relagrasped or held by standing or other pastive arrangement ofparts all as will be more fully. hereinafter set forth, as shown in the drawing andfinally pointed out in the appended claims.

. In the drawing Figure 1 is a view in elevation of a hand strap embodying the principles of my invention. Fig. 2 iso broken view in section on the line 2, 2, Fig. 1, look: ing in the direction of the arrows. Fig. 3 is a top plan view of the construction shown in Figs. 1 and 2,- Fig. 4 is a broken view, in transverse section of a portion of a car body showing. the hand strap support and the strap itself in its normally retracted position. Fig. 5 is a view in longitudinal section of a modified form of strap support embodying the broad principles of my invention. Fig. 6 is a view in section on the line 6, 6, Fig. 5. Fig. 7 is a view in elevation of another modification embodying the principles of my invention. Fig. 8 is a view in section on the line 8, 8, Fig. 7.

The same .part is designated by the same reference sign wherever it occurs throughout the several views.

Reference sign A, designates the hand strap or grip device designed to be grasped by a passenger on a street or other car, or in any other place where such a device is or may be employed or desired, and bymeans of which the person grasping the same may be steadied or supported. This hand grip or strap, while it may be of any suitable material, and of any desired shape or form adapting it to its purpose, is shown in the form. of a'loop with the bight of the loop forming. the grip portion to be graspedby the hand, as indicated in dotted lines 1n Fig.

4. If desired, and preferably, this grip is of metal or covered or coated with an enamel or other suitable material which, can be readily andeasily cleaned, thereby avoiding the danger of harboring or transmitting disease germs.

The hand strap may' be supported in the car or other place where it is to be used, in many different ways. I have shown various arrangements which I will now describe.

Referring to Figs. 1, 2, 3 and l, the ends of the hand strap are secured toa sleeve portion B, which is mo'unted on a tubular or other convenient. form of support C, which,

in this instance, though not necessarily is mounted in or carried by brackets D in the car, and in osition for the hand strap to be suspended therefrom and conveniently grasped. In this form of the device the sleeve portion B is of such length as to be afiorded sufficient bearing on the support C to prevent rocking or swinging movement of the strap in the direction of thelength of the car, or of the support C.

It may sometimes be desirable to permit the hand-strap when in use, to swing. in a direction transverse the length of the car, or laterally with reference to the support C.

It may also be desirable to retain the hand strap in a normally retracted position out of the way. In the accomplishment of these objects and purposes, I provide a yielding connection between the hand gri device and "tension of said spring being normally exerted to retain the hand strap retracted, as shown in Fig. 4. In use, however, the strap is readily swung downinto vertical position, as indicated in dotted lines, being free to vibrate laterally or transversely of the car but held against swinging movement longitudinally of the car. If desired, and in order to afl'ord a stop to limit the lateral swing of the strap device, the sleeve B, may be provided with a slot H, to receive the bent portion J, of the spring E, the base of said slot cooperating with the bent portion J to form a limit stop. A simple construction for securing the strap to the sleeve is shown, wherein the ends K, of the strap are bolted, riveted or otherwise fastened to I a stem L, formed on or with the sleeve.

It may sometimes be desirable to prevent any swinging movement of the hand strap when in use, while, at the same time, when not in use it is held in retracted position. In Figs. 5 and 6, have shown an arrangement embodying this idea, the strap itself being omitted. In this case'the sleeve portion B, is mounted upon the support 0', as before, but is of suflicient internal diameter to permit a relative movement laterally with respect to said support. A spring E, is mounted on the support and connected at the ends thereof respectively to the sleeve and support. This spring is somewhat peculiarly coiled upon the support, that is, the coils'thereof are displaced out of cylindrical form, as shown, to enable the spring to perform two functions, namely, to normally rock or swing the sleeve and with it, the hand strap, not shown, into a retracted position, and also, to bear the sleeve laterally away from the support, so as to carry the lug or projection M, out of engaging relation with respect to a seat or openlng N, in the support C. With this construction and arrangement it will be readily seen that in the normal retracted position, as shownv in full lines in Fig. 6, the lug or projection M, is withdrawn from the seat or recess N, and

the sleeve B, is rotatively displaced on its support. When, however, the hand strap is grasped for use, the sleeve is rocked axially by the downward swing of the strap against the torsion tension of the spring, the lug M riding over the exterior surface of the support 0, until it is brought into register with the seat or recess N, in the support and then a slight downward pull on the strap against the tension of the displaced coils of the spring causes the lug M, to enter the recess or seat N, thereby locking strap device against swinging movement in either a longitudinal or a lateral direction. By releasing the strap the lug M is raised out of the recess N, and the sleeve is again axially moved to retract the strap.-

In some cases it may be desirable to dispense with the feature of normally holding the strap device in retracted position when not required for use, but to hold the same rigid against rockin'g or swinging movement in any direction when in use. In Figs. 7 and 8, I have shown a construction embodying this idea, wherein the sleeve B is of larger interior diameter than the exterior diameter of the support C A stud or pin P, is secured to the sleeve and works loosely through an opening in the support 0 A spring E is interposed between the support 0 and a shoulder R, on the pin and normally exerts its-tension on said pin or stud and, through it, on .the sleeve B to movethe latter laterally with respect to the support C ,-and to hold the lower end of the pin or stud out of engagement with a seat or openingT, in the support. When the strap, not shown, is in use, a slight downward pull thereon will cause the spring E to be compressed and-the structions em odying the principlesthereof,

what I claim as new and useful and of iny own invention and desire to secure by Letters Patent is':

1, The combination with-a hand strap, of a sleeve to which the ends of the stra are connected, and a support on which the s eeve is mounted.

2. The combination with a hand strap, of a sleeve'having a stem, the ends of the strap being secured to said stem, and a support on which said sleeve is mounted.

3. The combination with a hand strap, a sleeve to which the ends of the strap are connected, and a support on which the'sleeve is mounted, of means for normally maintaining the sleeve rocked to hold the strap in retracted .position.

4. The combination With a hand strap, a sleevetowhich the ends of the strap are connected, a support for the sleeve, and a spring iis connecting said sleeve and support and opcrating to normally retain the strap in res tracted position.

5. The combination with a hand strap, a sleeve to which the ends of the strap are connected, a support for the sleeve, a spring. respectively connecting the sleeve and support, and a limit stop to limit the swing of the sleeve on the support.

6. The combination of a support, a spring said support and sleeve, and a hand strap 10 coiled thereon, a sleeve mounted on said suphaving its ends connected to said sleeve. port, the ends of said spring being connected In testimony whereof I have hereunto set to said support and sleeve respectively, and m hand in the presence of the subscribing 5 a rigid hand strap connected to said sleeve. w1tnesses,on this 8th day of May A. D., 1909.

7. The combination of a support, a spring JAMES S. DOYLE. coiled thereon, a sleeve mounte on sai sup- \Vitnesses: portand inclosing said spring, the ends of J. E. KLEIN,

said spring being connected respectively to CLARENCE HUNICKE.
