Specification of Letters Patent. Patented Sept. 17, 1918.

Application filed February 20, 1918. Serial No. 218,262.

To all whom it may concern Be it known that I, RICHARD BABCOCK, a citizen of the United States, residing at Barcroft, in the county of Alexandria and State of Virginia, have invented certain new and useful Improvements in Fastening Means, of which the following is a specification.

This invention relates to fastening means or connecting devices, and resides especially in the means for readily fastening or anchoring the links of a chain or part or parts of some element or elements, and in provision for locking said means in normal position.

The invention hereinafter set forth and described is intended primarily for use in attaching anti-skidding chains, of the fixed point or anchored type, to the felly or other part of an automobile truck wheel. ever, the invention may be embodied in a number of forms to be fixed in position in primarily intended for use with anti-skidding devices, as above mentioned, it can be used equally well for a great variety of purposes.

The primary object of the present invention is to provide a plate with a pivotally mounted bar having oppositely disposed arms at ends, which arms, are adapted to re ceive ordinary twisted chain links and have their ends received in recesses in said plate when said bar is in normal position.

A further object is to provide means for releasing said bar and for locking 1t in nor- 1 mal position, the arrangement and construction of the parts being so calculated as to throw the minimum amount of strain on said means when all parts are in normal position with an anti-skidding, or other, chain or chains applied to the arms.

A further object is to provide sufficient clearance between the arms and the plate to allow the chain links, or other elements, to he slipped over the ends of the arms.

A further object is to so form the bar, plate and releasing and locking means that the three elements will constitute a self-contained unit, no part of which can become separated, by manipulation by hand or with any ordinary tool, and so become lost. Quite commonly persons operating trucks are not mechanically inclined and might separate the parts without need and then lose one or more of the parts. With this fact in view How-V it is desirable to so after being assembled difiicult to separate.

In the accompanying drawings, in which only the preferred form is illustrated;

Figure 1 represents a perspective view of a device embodying the invention; I

Fig. 2,. a plan View thereof; I V

Fig. 3, a cross sectional view on the line 33 of Fig. 2; and

Fig.4, a cross sectional view on the line 44L of Fig. 2, looking in the direction of the arrows.

Referring now in detail to the drawings,

A indicates the plate having at each end and on opposite sides a perforated lug B through which any suitable fastening device, such as a bolt or lag-screw, not shown, may be passed to fasten the plate to the felly of a truck wheel or to any other relatively fixed object.

. This plate .A is provided at each end and on opposite sides with a preferably recessed lug preferably formed integral with the plate, eachlug extending preferably about three-fourths of the length of the plate and toward, the other end thereof.

1 designates one of these lugs, which is preferably plain and solid, except for its recess 3 and 2 designates the other of said lugs, whichis also preferably plain except for its recess 3 and a slot 4 extending through said lug and transversely thereof.

The portion of said plate between said lugs ,1 and 2 is provided with a preferably integral raisediOl long portion or'shoulder 5 and is provided at its central point with a perforation throughwhich passes a pivot pin 6. v

A- spacing collar 7 is slipped over the upper end of pin 6, the bar 8 is then slipped form the parts that and finished they are over the upper end of said pin and the ends 7 ofthe pin are then upset or spread, as clearly-shown in Fig. 3, leaving, however, sufficient play to permit the turning or pivoting of the bar 8 thereon.

- A releasing and locking bolt 9 is inserted in the slot 4 and has its inner end bifurcated to receive between the bifurcations 10 thereof a portion of the bar 8, which portion of said bar and the bifurcations 10 are perforated to receive a pivot pin 11, the ends of which are upset or spread for obvious reasons.

The outer portion of this bolt 8 is screwthreaded a receive a wing-nut12, which is preferably round and of sufiicient size to generouslyspan the slot l. After'the nut has been screwed on the outer-portion of bolt 8 the extreme outer end thereof will be preferably upset or spread as at 13 to prevent the separation of the nut 12 therefrom.

The bar 8 above referred to is provided on each end with an arm 14, said arms being disposed in reverse directions and having their outer ends received, in normal position, in the respective deep recesses 3 in the respective lugs l and 2. The opposing faces of said arms are each provided with a recess 15, the deepest point of which lies on the central longitudinal line of said plate A, which line also passes through) the axis of pin 6, so that the terminal links G of the chain or chains or other element or elements will engage the arms at this point and pull in diametrically opposite directions, throwing practically all the strain on the arms 14,

bar 8 and plate A and putting practically no strain on the: pin 6 and the bolt 9 with its bifurcations 10 and the pin 11.

In operation, to apply the chain links G.- or other elements to be connected, fastened will be unscrewed or anchored, the nut l2 sufficientlyto allow the bar 8 to be, turned on pin 6 until the ends of arms 14: lie on the longitudinal central line of plate A, when the links C may be slipped over the ends of said arms 14a The nut 8 will then be screwed up on. the bolt 9 until: the ends of said'arms 14E are held firmly against the inner walls of the recesses 3. Toremove the links C the same operation is repeated, exceptthat the links C are withdrawn from the arms-instead of being applied thereto, and the only reason for tightening the nut 8 then will be to prevent rattling.

The slot 4 is of course,

sions to allow the inner end of the bolt 9 to describe an arc of sufficient magnitude to allow the ends of arms 1 L to lie on the longitudinal' central line of. plate A, with pin 6' as the center of such arc.

It is obvious, of course, that in case the arms 14 or bar 8 should become stuck in,

normal position, by ice or other foreignv matter, it may be quickly freed by tapping the free end of the bolt 9.

The bar- 8 with its arms 14 will preferably be of drop-forged steel, though any suitable material may be used for this part as well as any other parts of the device.

Having thus described my invention, what (topics of this palcnt may be obtained for of sufiicient dimen-- l claim as new and desire to secure by Letters Patent is:

1. A plate provided with a recessed lug on each end and on opposite sides, in combination with a pivotally mounted bar having oppositely disposed arms, the ends of which are located in said recesses when said bar is in normal position, and means for locking said her in normal position.

2. A plate provided with a recessed lug on each end and on opposite sides, in combination with a pivotally mounted bar having oppositely disposed arms, the ends of which are located in said recesses when said bar is in normal position, and means for locking said bar in normal position, the opposing faces of the upset arms being recessed, the deepest part of each recess cutting the axis of the pivot of said bar.

3. A plate provided with a recessed lug on each end and on opposite sides, in combination with a pivotally mounted bar having oppositely disposed arms,the ends of which are located in said recesses when said bar is in normal position, a bolt pivotally connected to said bar and extending through one of said lugs and a nut working on said bolt and adapted to engage the external face of said lying on a line lug to hold said bar in normal position,-the

extreme free end of said bolt being spread to prevent removal of said nut therefrom.

4. A plate provided with a recessed lug onder, in combination with a bar pivotally mounted ona pin passing through said perforation and provided with oppositely disposed arms having their ends received in said recesses when said bar is in normal position and means for holdingsaid bar in normal position.

5. A plate provided with a plurality of recessed lugs, bar mounted for movement on said plate and having arms the respective ends of which are adapted to be received by the respective recessed lugs when said bar is in normal position, and said bar in normal posit-ion, each of said arms being adapted to receive an endless article when out of normal position.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
