To all whom it may concern.

Be it known that CHARLES L. DAVIS, a citizen of the United States, and resident of Santa Barbara, county of Santa Barbara, and State of California, has invented certain new and useful Improvements in Spine- Treating Apparatus, of whichthe following is a specification. I

This invention relates to spine stretching or exercising apparatus and the object is to provide an apparatus ofthis nature which is portable and embodies means enabling V the apparatus to be set up for operation at any desired point, thus dispensing with permanent fixtures and pulley arrangements of the type heretofore employed. I A further object of the invention is to provide an improved head harness which may be quickly applied in position and is self-adjustable to fit various sizes of heads and to equalize the pressure between the front chin strap and the back head strap.

A still further object of the invention is to provide an improved portable support ing bracket over which an operating cable attached to the head harness is adapted to pass.

Other objects of the-invention, as well as the details of construction, combination and arrangement of parts constituting the pre ferred embodiment disclosed herein will be more readily understood from the following description and accompanying drawings; in which,

Fig. 1 is a view of my device as it will appear in use.

Fig. 2 is a fragmentary perspective view of the device showing the construction of the head harness and the manner in which the same is attached to the operating cable.

Fig. 3 is a detailed sectional View on the line 33 of Fig. 1.

As herein disclosed, the invention contemplates the provision of a head harness embodying rings 5 and 6 carrying an endless strap 7 which is passed through said. rings to provide a front chin engaging portion 7 and a backhead engaging portion 7", these two portions. being stitched together at the point 8 to anchor the strap to the ring 5, while permitting free sliding movement of the strap through the ring 6. Due to its slippage through the ring 6, the strap 7 is rendered self-adjusting to fit various types of hemmed" to equalize the pressure between the front and back engaging

portions

7 and 7 The rings 5 and 6 are secured to the ends of a connecting strap 9 carrying slidably a further ring 10 to which is anchored one end of a cable 11. This cable is trained for sliding movement over a suitable bracket 12 and is equipped at its free end with a handle member 13 so that, as shown in Fig. 1, the wearer of the device can exert the required tension on the head harness by pulling downwardly on the handle. As disclosed herein, the bracket 12 consists of a vertical portion 13 provided at its upper end with a rearward projection 14 and at its lower end with a forward projection 15. The projection 14 is preferably in the form of a horizontally extending block screwed or otherwise secured to the back of the portion 13 and adapted to rest on a head casing 16 or other suitable support. Preferably the projection 14 is provided with anti-slipping devices 17 to hold the same in a fixed position on the support 16. The lower or front projection 15' is in the form of a half-sheave screwed or otherwise tour of the cable and to enable the said end of the latch member to closely approach the grooved surface of the sheave 15 to prevent side movement of the cable, as shown. to advantage in Fig. 3.

By reason of the particular construction of the bracket 12 it will be evident that my device as a whole is of a portable nature capable of being conveniently set up at any designated point where there is a support equivalent to the element 16 disclosed herein.

A further advantage of the construction set forth herein is the self-adjusting feature of the head harness and the ease with which said harness can be applied or removed,

The particular manner in which the strap 7 is connected to the rings 5 and 6 and through the strap 9 to the cable 11 is of advantage in that it provides for the requisite equalization of pressure between the front and back strap portions 7' and 7".

In the foregoing, I have disclosed What I now consider to be a preferred embodiment of my invention but it Will be understood that any desired modifications may be made Within the scope of the appended claim.

What I claim is:

An apparatus of the class described, comprising a head harness, a bracket member presenting a seml-olrcular groove a cable shdable 1n said groove and attached at one end to said harness and a latch member piv- 15 oted to said bracket and normally disposed to hold the cableagainst escape from said groove.

In testimony whereof I hereunto afiix my signature.

CHARLES LESTER DAVIS.
