SUSPENDERS.

SPECIFICATION forming part of Letters Patent No. 549,245, dated November 5, 1895. Application fledIebruary 23,1895. Serial No. 539,523. (No model.)

To @ZZ whom t may concern:

Be it known that I, EDWIN F. MERWIN, a citizen of the United States, residing at New York city, in the county and State of New York, have invented a new and useful Improvement in Suspenders, of which the following is a full, clear, and exact description.

My invention relates to an improvement in suspenders, and especially relates to the construction of the forward ends thereof.

The object of the invention is to support the trousers by the side or pivotal button by means of the principle known in mechanics as the block and tackle, reducing the resistance to muscular motion in proportion to the number of strings and pulleys applied. Thus two strings over one movable pulley reduce one-half, three strings reducing approximately to one-third. The strings or cords may be of firm material or of elastic material. IVhen of elastic material, the highest degree of freedom of movement is attained. Vhen applied to the sliding web end, it produces a similar though modiiied result.

The invention consists of the novel construction and arrangement of parts hereinafter set forth and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which are represented the ends complete for attachment to the body of any ordinary type of suspender, either elastic or non-elastic, buckle, or slide.

Figure l represents a suspender-end of the two-string type; Fig. 2, a suspender-end of the three-string type, and Fig. 3 a suspender-end of the two-string type formed of webbing.

In the drawings, l is a plate for holding a sheave 4 and the fixed point of leverage 3, movable sheave 5, attached to plate 2, which carries a loop 7 for attachment to the side or pivotal button of the trousers. It will be readily seen that the cord 6, passing over sheave 4 and 5 to the fixed point 3, supplies two strings for the support of loop 7, thereby enabling one-half the power applied at loop 8 to support loop 7. In Fig. 3 the flat web 6, passing overbars 4 and 5 to attaching-bar 3, produces the same result.

the advantage gained by the mechanical appliance.

The great advantages in supporting the trousers at point 7, the pivotal button, are, first, that only the weight of the trousers is supported by the shoulders and by a perpendicular lift, the power at S never being sufoient to divert the lift from a direct perpendicular line; second, it never pulls the two front buttons together, as is the casein all ordinary ends, whether of the rolling or iiXed type, as in them the lift is appliedl about equally in the center of the two lateral branches, thereby drawing the two ends and buttons together, causing distress and uneasiness to the wearer from resistance of the person added to the weight of the trousers; third, the whole appliance is calculated to give ease and comfort to the wearer to reduce friction, as a considerable movement either forward or backward will make but a slight change at point 7, and, lastly, it relieves the buttons from strain and the shirt-bosom from being crushed.

What I claim, and desire to secure by Letters Patent, is-

In a suspender end attachment, a cord or web having a buttonhole upon its free end means to which its opposite end is attached adapted to be connected to the shoulder strap, the said cord or web being looped or doubled upon itself, intermediate its ends, suitable guiding devices over which the cord or web passes, and a buttonhole loop device loosely carried by the looped portion of the cord or web, substantially as described.
