ANTISLIPIING DEVICE.

To all whom it may concern:

Be it known that I, HARRY A. SARVER, a citizen of the United States, residing at Parkersburg,'in the county of Wood and State of West Virginia, have inventedv certain new and useful Improvements in Antislipping Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in anti-slipping devices and has relation more particularly to a device of this general character especially designed and adapted for use in connection with the' wheels of motor-driven vehicles; and it is an object of theinvention to provide a device of this general character having novel and improved means whereby the same may be readily and conveniently applied intoo'penative position.

It is also an object of the invention to provide a novel and improved device of this general character comprising a plurality of operatively connected sections, each of said sections being provided with means to prevent slipping in either a circumferential or lateral direction. 1

The invention consists in the details of construction and in the combination and arso rangement of the severalparts. of my improved anti-clipping device whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advan- 85 tageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed. In order that my invention maybe the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a fragmentary view in elevation illustrating an anti-slipping device constructed in accordance with an embodiment of my invention and in applied position;

Fig. 2 is a fragmentary view in plan of an anti-slippingrdevice as herein set forth; Fig. 3 is a agmentary view partly in elevation and partly in section illustrating certain details of construction as herein em: bodied;

trating afurther embodiment of my invention.

As disclosed in the accompanying drawmgs, my improved anti-slipping device includes a plurality of sections S adapted to extend longitudinally in a direction circumferentially of the tread portion of the tire T of a wheel and which includesa centralelongated member 1 disposed longitudinally on-a predetermined curvature and which is provided-at its opposite ends with the outwardly disposed diverging extensions 2. The extensions 2 are also arranged longitudinally on a predetermined curvature so that when the section S is in applied position upon a tire, the elongated member 1 together with the branches or extensions 2 will conform to the-peripheral configuration of the tire T.

The outer face'of' the elongated member 1 is provided with a longitudinally disposed calk 3 having its engaging edge disposed on a curvature substantially concentric to the periphery of the tire T,'said calk 3 serving to hold the wheel or tire against lateral slipping movement or skidding. The member 1 is also provided at a point substantially midway the length of'the calk 3 with the laterally disposed supplemental calks 4 which serve'to prevent circumferential slipping of the wheel or tire. I

The outer end portion of each of the branches or extensions 2 is provided with an enlargement 5 with which is engaged a calk 6 preferably in the form of a truncated pyramidand which serves to afford an effective grippingaction especially when the wheel or tire is traveling over ice, snow, mud or the like.

The sections S are rigid and preferably formed of metal and adjacent sections S are connected one to the other through the medium of the tie members 7 and 8. As herein disclosed, each of the members 7 consists of an elongated bar or rod 9 having its extremities in swiveled engagement, as at 10, with adjacent calks, 6 and provided intermediate its length with an eye 11. Connected with the eye 11 is a flexible member 12 suitably anchored to a Patented May 29, 1917.. Application filed November 25, 1916. Seria1 No.133,424.

flexible member 14 disposedv circumferentiallyof the tire of the coacting rim R. The flexible members 14 are two in number and arranged at opposite sides of the tire T or rim R and the extremities of each of said members are suitably connected one to die other, as indicated at 15, whereby it will be perceived that the sections S will be efiectively held in applied position upon the tread portion of the tire T.-

The members 8 as herein in the form of a linked chain and having their outer portions laterally disposed through suitable openings 16 in the adjacent enlargements 5. This 'form of connectingmember is affordedto permit my improved anti-slipping device to beiolded or compacted to occupy a minimum ofspace and which is particularly desirable when the device is not in use. Itis to be also noted that one of the intermediate links 11 serves as an eye with which a flexiblemember 12 may be engaged.

Certain of the sections S are capable of detachable connection one with the other, as indicated at 17, so that the application of my improved device may be materially facilitated. a

In the form of invention illustrated in detail Fig. 5 it is to be noted that the connecting bar or rod 9 is provided adjacent its opposite ends with the eyes 11 with each of which a flexible securing member is adapted to be engaged. I have found in practice that by providing each bar or rod 9 with a plurallty of eyes 11 additional strength is afforded the anti-slipping device.

'From the foregoing description, it is thought to beobvious that an anti-slipping device constructed in accordance with .my'

invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it maybe assembled, and it will also be obvious that my invention is susceptibleof some change and modification without material departure from the'principles and sp1rit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

1. An anti-slipping device com rising a sections plurality of sections, each of sai including an elongatedmember provided embodied are with diverging extensions adjacent its opposlte ends, sald member and extenslons being provided with calks, and means for connecting adjacent ends of said sections plurality of connected sections adapted to be disposed circumferentially of a tire, each of said sections including an elongated member provided adjacent its opposite ends with diverging. extensions, a longitudinally disposed calk carriedbythe member, and a calk carried by the outer, end portion of each of the extensions.

' 4:. An anti-slipping device comprising a plurality of connected sections adapted to be disposed circumferentially of a tire, each of said sections including an elongated member provided adjacent its opposite ends with diverging extensions, a longitudinally disposed calk carried by the member, a calk carried by the outer end portion of each of the extensions, and means coacting with said last named calks for securing adjacent sections one to the other.

5. An anti-slipping device comprising a plurality of connected sections adapted to be disposed circumferentially of a tire, each of said sections includin an elongated member provided adjacent 1t's opposite ends with diverging extensions, a calk carried by the outer end portion of each of the extensions, and means in swiveled connection with thev calks for connecting adjacent sections. j

In testimony whereof I hereunto afix my signature in the presence of two wltnesses.
