CLAMP.

Application led March 11, 1920.

To @ZZ wlw-m t may concern:

Be it known that I, ARTHUR L. COCHRANE, of the city of Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Clamps, of which the following is a specification.

This invention relates to devices for fastening ropes, ties, laces and the like, and my object is to devise a clamp which is of simple construction, inexpensive to manufacture, easily and quickly engaged and released, and which will hold the end of a lace in a bow if desired.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which Figure' l is a plan view of my improved clamp in its simplest form;

Fig. 2 a longitudinal section of the same;

Iiig. 3 a plan view of an elaborated form; anc

Fig. 4 a longitudinal section of the same.

Fig. 5 is a plan view of a modified form of my clamp.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

Referring particularly to Figs. l and 2, l is the body member, preferably formed of sheet metal and having a forwardly extending tongue 2. To the body member is pivotally connected the clamping member 3 formed as an open quadrangular frame, its outer end being shaped and adapted to cooperate with the outer end of the tongue to form clamping means as will be understood particularly on reference to Fig. 2. Gne side of the frame may be omitted as shown in Fig. 5. To form bearings for this clamp member I stamp up from the body member hook lugs 4 with which the inner end 5 of the clamp member 3 is engaged.

Integral with the body member is formed a spring plate 6. In the form shown in Fig. l, this plate is formed by stamping up a tongue from the metal of the body member. In the form shown in Figs. 3, 4 and 5, the spring plate l is formed by bending the body member upon itself at the outer end of the tongue 2. The inner end 5 of the clamp member is provided with a flat so that when the spring is engaged with this fiat as shown in the drawings, the spring tends to hold the outer end of the tongue 2. This Specification of Letters Patent.

prevents any possibility of a lace or tie becoming loosened when subjected alternately to tension and release from tension. I prefer also to form a second 'flat on the inner end 5 of the clamp member adapted to be engaged by the spring to yieldingly hold the clamp member with its outer end in a convenient position when the lace or tie is to be inserted in the device, or withdrawn fromthe same.

The upper ends of the hook lugs 4 are preferably bent outwardly to provide finger pieces which may be gripped when it is desired to lift the body member of the buckle when disengaging a tie therefrom. When the device is being used as a fastener for shoe laces and the like it is desirable that the end of the lace shall be held in a bow-like form. For this purpose I provide a loop behind the bearings of the clamp member, which loop is preferably formed by means of one or more inwardly bent lugs 7 stamped up from the body member 1. In Fig. 5 the loop is formed of a simple lug and hence is open at one side so that a tie may be drawn into it from the side. As the clamp member is also open at one side it is evident that with the construction shown in this figure of the drawings the tie may be engaged with the clamp without any threading movements being necessary. The spring 6 may be extended to pass under this loop, or the clip itself may form a spring (see Fig. 5), hence if the lace be drawnthrough or caught beneath the loop as indicated in Figs. 4 and 5, it will be securely and neatly held. The use of this loop also adds additional security to the fastening as the lace may be held taut between the point at which it is gripped by the tongue 2 and the outer end of the clamp member, and the point of engagement by the spring and the loop 7, or spring loop.

,In Figs. 3 and 4 I show an extra set 8 of bearing lugs, which enables the clamping member to be adjusted to enable it to be used with flexible tie members of different thicknesses.

What I claim as my invention is l. A clamp comprising a body member formed with a forwardly extending tongue; a clamp member formed as an open quadrangular frame pivotally connected by its inner end to the body member and having its outer end adapted to coperate with the outer end of the tongue to form clamping means; and a spring plate integral with the body member engaging the inner end of the clamp member, the latter having a flat thereon engageable by the spring, whereby the latter tends to hold the clamp member in clamping position.

2. A clamp constructed as set forth in claim l having` a second flat on the inner end of the clamp member engageable by the spring to tend to hold the clamp member somewhat below its cooperative position relative to the body member.

3. A clamp constructed as set forth in claim l provided behind the pivotal connection of the clamp member with a loop with which the spring cooperates and under which the rope or lace with which the de- -vice is used may be drawn after passing` beof resilient sheet metal havingl an integral' part thereof behind the pivotal connections of the clamp member extending up and then inwardly to form a loop with which the spring cooperates and under which the rope or lace with which the device is used may be drawn after passing between the clamping means.

5. A clamp comprising a body member formed with a forwardly extending tongue; a clamp member formed as an open quadiangular 'frame pivotally connected by its inner end to the body member and having its outer end adapted to cooperate with the outer end of the tongue to form clamping means; and a loop member, behind the pivotal connections of the clamp member,

through which the rope or lace with which he device is used may be drawn after passing` between the clamping means.

6. A clamp comprising' a body member `formed of sheet metal formed with a forwardly extending tongue and turned-up hook lugs forming bearings; a clamp member formed as an open quadrangular frame having its inner end pivoted in said bearings and having` its outer end adapted to coperate with the outer end of the tongue to iorm clamping means; and a spring plate integral Vith the body member engaging the inner end oi the clamp member, the latter having a flat thereon engageable by the spring, whereby the latter tends to hold the clamp member in clamping position.

7. A clamp comprising' a body member formed of sheet metal formed with a forwardly extending' tongue and turned-up hook lugs forming' bearings; a clamp member formed as an open quadrangular frame having` its inner end pivoted in said bearings and having' its outer end adapted to cooperate with the outer end of the tongue to Jform clamping' means; integral lugs on the plate behind the bearings then inwardly to ward one another to form a loop; and a spring integral with the plate extending through said loop.

8. A clamp constructed as set forth in claim 9 in which the inner end of the frame has a ilat thereon engageable by the spring, whereby the latter tends to hold the clamp member in clamping` position.
