TRACE-HOLDER.

To all whom it may concern:

Be it known that I, Brennan C. MoKAY, a citizen of the United States, residing at Atlanta, in the county of Steuben and State of New York, have invented a new and useful Trace-Holder, of which the following is a specification.

This invention relates to trace holders, which are devices fastened on the ends of whilfietrees to prevent harness traces from slipping off or being disconnected therefrom.

The object of the invention is to provide a device of the character described which shall be strong, simple and cheap, of few parts and capable of holding a harness trace in place on the end of a whiifietree with great security.

A further object of the invention relates to the arrangemei'it of the spring for acting on the pivoted finger of the holder, whereby a strong tension is maintained to prevent said. pivoted finger from moving out of place by the jars and strains on the Whittletree or the finger itself.

lVith these objects in view, the invention consists in the novel construction, combination and arrangement of parts, hereinafter described and claimed reference being had to the accompanying drawing, in which- Figure 1 is a perspective view of the improved trace holder fastened. on the end of a whifiietree, the trace being shown in dotted lines. Fig. 2 is a side elevation of the trace holder, the frame being shown in section. Fig. 3 is a plan view of the same, and Fig. 4 is a cross section on the line 4-4 of Fig. 2.

Similar reference numerals are used for the same parts in all the figures.

The casing or frame 1 of the trace holder is preferably made of sheet metal stamped and shaped by suitable machinery into the form shown, which comprises two spaced vertical side plates 2, 2, parallel to each other and each having a base flange 3 at a right angle to its respective plate extending outwardly therefrom. The side plates 2 are inclined at the top from one end to the other, and connected by an integral cover 4 extending from the lower ends of the plates nearly to the limit of the higher ends. The lower end of the cover 4 has an extension or tail 5 which, when the parts are assembled, is turned under the cover 4 to hold the spring 6. Between the higher ends of the plates 2 is placed one end of a curved Specification of Letters Patent.

5 swinging finger 7, pivoted on a pin 8 passing through a hole in each side plate and riveted. curved concentrically with the pin 8.

The swinging finger 7 is made with a curved intermediate portion 9 having on one end a hub 10, through which the pivot pin 8 passes, and its other end straight to rest on the whiftletree and form an abutment for the trace end. The hub 10 is curved on its upper and lower edges and passes below the cover 4 in close relation therewith to prevent the entrance of moisture and dirt. A notch 11 is made in the rear of the hub to receive the free end of the fiat spring 6 which holds the finger against the whiffietree. A thumb piece 12 projects from the finger 7 by means of which it is raised to permit the passage of the trace end. The position of the notch 11 with respect to the axis of revolution of the finger 7 and the line of the spring 6 is such that when the finger is in operative position, the notch will be above the pivot of said finger and the tension of the spring holds the point of the finger close against the whiffietree. When the trace end is to be forced on, or removed from the whiflietree, the finger is raised to the position shown by dotted lines in Fig. 2. This movement carries the notch 11 below the pivot pin and the finger is held in elevated position by the resiliency of the spring acting on the finger below its axis. The base flanges 3 on the side plates 2 project outwardly therefrom at their longitudinal centers sufficiently far to enable fastening screws 13 to pass through them into the whiifletree and tapering thence in each direction to the ends of the frame or casing 1.

The operation of the device is self evident and a detailed description thereof will not be necessary. The hub 10 is as wide as the space between the plates 2 and. as its lower and upper edges lie close to the whifiietree and cover 4, respectively, dirt, mud and moisture is thereby prevented from entering the casing, thus protecting the parts from becoming clogged and rendered noneffective by foreign substances entering the casing and between the movable parts. The free end of the spring rests in the notch in the hub of the finger and bears endwise against the bottom of said notch, holding the finger against the whifiletree or in elevated position. When the finger is raised the notch The corners of said side plates are presses against the end of the spring which offers more resistance to the movement of the finger than it would were pressure brought against the side of the spring. By this arrangement the finger is held firmlv. either open or closed, with a small spring.

I claim:

1. A trace holder comprising a hollow casing. a curved finger pivoted between the side plates of said casing at one end and having a notch in rear of its pivot, and a fiat spring attached to the other end of the casing with its free end seated in said notch pressing endwise against said finger and adapted to hold the latter in closed or open position.

2. A trace holder comprising an integraln stamped and folded casing or frame higher at one end than at the other, a finger pivoted between the side plates of said frame and closing the opening thereinto, and a spring fixed at one end to said casing with its free end engaging a notch in said curveu finger and pressing endwise against the same, said free end of the spring adapted to be carried across the pivot of said finger to hold said finger in either open or closed position when moved thereto.

- 3. A trace holder comprising an integrally stamped and folded casing or frame, the spaced sides of which are joined above by a downwardly inclined cover having a projection on its lower end, a curved finger having a hub on one end pivotally connected to said side plates and extending beneath the cover and in close relation thereto a notch being formed in said hub below said cover, and a straight fiat spring fastened to the frame by folding said projection inwardly and having its opposite end seated in said notch and pressing against the hub in an endwise direction.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
