To @ZZ 'whom traag/concern." j

j Be it known that I, WILLIAM R. SENFTLE,

a' citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements inHanger-Straps for Street- Cars, of which the following -isa specifi'- tion.

This invention relates to hanger-straps -or handholds for street and other cars and more particularly straps of this character having' a grip or loop of sheet metal or other rigid material.

lVhile straps of this kind have certain advantages over ordinary leather straps, their hardness and rigidity render them more liable to injure passengers and mar the wood work and other parts of the car.

One of the objects of my invention is the provision of simple and effective means for checking or retarding the swinging of the hangerstrap, to avoid the above objections, while at the same time permitting the necessary freedom of movement of the strap as well as twisting thereof when grasped by a passenger, in order that it may be as comfortable as the ordinary leather strap.

A further object is the production of a neat and comfortable hanger-strap which'is strong and durable in construction.

In the accompanying drawings:

Figure 1 is a sectional edge view of the improved hanger-strap suspended from a car-ceiling or other suitable support. Fig. 2 is a sectional elevation of the strap at right angles to Fig. l. Figs. 3 and 4 are transverse sections on the correspondingly numbered lines in Fig. 2. Fig. 5 is a cross section of the grip showing a modification thereof.

Similar characters of reference indicate corresponding parts throughout the several views.

l indicates the grip or loop of the hangerstrap which may be of any suitable construction. In its preferred form, it has a convex inner face and a channeled or concave outer face and is stamped from a blank or strip of sheet metal of appropriate thickness having its marginal portions 2 doubled upon itself. These marginal portions meet in a joint 3 extending lengthwise of the grip and located centrally on the outer side of the grip, as shown in Fig. 3. However, if desired, the joint may be located on the convex or inner side of the grip, as shown at 3a in Fig. 5.

, The strap is suspended from the car-oeil ing vor other support by any suitable mea-ns, the preferred device shown in the drawings consisting of a pin or stem 4 seated in a socket 5 secured to the car-ceiling and confined therein by a transverse bolt 6, as shown `in the drawings. The upper'end of the'grip' is connected with the stem 4 by a chain or other flexible connection 7 which may be welded or otherwise fastened to said parts. Surrounding this chain is a flexible or resilient restraining tube 8 which is adapted to prevent undue swinging -motion of the hanger-strap when hanging freely and yet allow it to twist more or less and sway with the passenger when grasped by him. In the preferred embodiment of the invention shown in the drawings, the tube 8 consists of a do-uble spiral spring which is welded or otherwise fastened at its lower end to the upper end of the grip, as shown at 9, while its upper end surrounds the stem 4. When such a double spring is employed, the convolutions 8d of the inner windings preferably break joint with those of the outer winding, to produce a practically closed flexible connection between the grip and the suspension member 4. 4The latter extends a short distance into the tube so that only the portion of the tube below said stem is capable of iexion.

hile a double spring is preferred, a single spring may be used, if desired.

By this construction, the chain 7 receives the strain exerted on the hanger-strap by the passenger while the tube 8 prevents undue swaying of the strap when free, which would be permitted by the chain without such a restraining element.

The most satisfactory results are obtained by constructing the tubular connection 8 in the form of a spring, but I do not wish to be confined to such an elastic tube, inasmuch as a flexible non-resilient tube would restrain the hanger-strap and is therefore regarded as coming within the scope of my invention.

If desired, the grip 1 may be coated with enamel or other suitable material which renders the grip non-absorbent and sanitary.

I claim as my invention:

1. A hanger-strap, comprising a fiexible connection adapted to be attached to a support, a grip carried by said connection, and flexible means for resisting swaying of the o'rip.

o 2. A hanger-strap, comprising a. exible Connection adapted to be attached to a sup- )ort a Uri carried b said connection and 7 C 9 a flexible tube surrounding said connection. 8. A hanger-strap, comprising a flexible connection adapted to be attached to a support, a grip carried by said connection, and a restraining spring surrounding said connection.

4. A hanger-strap, comprising a flexible connection adapted to be attached to a support, a grip carried by said connection, and

a flexible tube surrounding said connectionl and attached to the grip.

5. A hanger-strap, comprising a grip, a

'said suspension member.

6. A hanger-strap, comprising a grip, a

flexible connection carrying said grip and adapted'to be attached to a support, and a tubular restraining spring surrounding said connection, said spring consisting of inner and outer convolutions arranged to break joints. A WILLIAM R. SENFTLE.
