TRIP CAR-STANDARD.

To all whom it may concern:

Be it known that I, WILMo'r STRATHY, a citizen of the United States, residing at Monterey, in the county of Highland and State of Virginia, have invented a new and useful Trip Car-Standard; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved trip standard for railroad cars, lumber wagons, sleds, bunks and vehicles generally used for the transportation of logs and lumber; and the invention has for its object to provide an improved trip standard which is hingedly supported in such a manner as to enable it to be dropped out of the path of the logs and lumber when it shall be desired to unload the same.

Afurther object of the invention is to provide an improved locking mechanism for supporting said trip standard in position for operation.

A further object of the invention is to provide a standard with a foldable extension member.

A further object of the invention is to provide guiding means for the arm or brace which constitutes a part of the locking mechanism.

Further objects of the invention are to simplify and improve the construction and operation of this class of devices.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings there have been illustrated certain simple and preferred forms of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the inven tion may be resorted to when desired.

In the drawings-Figure 1 is a side elevation illustrating one form of the invention. Fig. 2 is a side elevation of the same showing the standard in a non-obstructing position. Fig. 3 is a plan view of Fig. 1. Fig. 4 is a side elevation of a modified form of the invention. Fig. 5is a side elevation, partly in Specification of Letters Patent.

section, showing a modified form of Fig. 1. Fig. 6 is a perspective detail view illustrating the guiding means for the brace arm. Fig. 7 is a perspective view illustrating a modified form oi said guiding means.

Corresponding parts in the several figures are denoted by like characters of reference.

In the several figures oi the accompanying drawings only one end of a car or wagon bolster has been shown, it being understood that a trip standard is usually provided at each end of the bolster.

The trip standard A, is hingedly connected with the bolster B, adjacent to the end of the latter by suitable means such as a bolt 5. The standard may be constructed of malleable iron or other suitable material, and the standard as well as the cross-beam or bolster may be suitably recessed or mortised so as to enable the parts to be properly fitted together.

Pivotally connected with the standard A, at no great distance from its upper or outer end is a curved or arcuate brace arm 6, the lower extremity of which extends in an inward direction with reference to the boX or bed of the car, wagon or other vehicle equi ped with the bolster B a stout hook 7, whic I term latch hook is hingedly connected with the brace arm 6 by means of a bolt rivet 8, 9 designates the bolt whereby thei brace arm 6 is connected with the standart 6.

The bolster is provided with a suitably located latch stud 10, adapted to be engaged by the latch hook 7, and it is also provided with a guiding stud 11, adapted to be engaged by the curved brace arm 6, and located adjacent to the concave upper edge of said arm. The latch stud 10 and the guiding stud 11 are so situated that when the standard A is raised to an upright position, approximately at right-angles to the cross-beam or bolster, and said studs are engaged respectively by the latch hook 7, and the brace arm 6, said standard will be retained very securely in an upright position against any strain that is liable to be exerted thereupon by logs, lumher or other material loaded u on the vehicle embodying the bolster B it will be seen that strain exerted against the inner side of the standard will have a tendency to force the brace arm 6, upward against the guiding stud 11 while a straight direct pull is exerted by the latch hook 7 upon the latch stud 10. The studs 10 and 11 are preferably equipped with cylindrical shells or rollers 12, constituting anti-friction devices for the purpose of facilitating the operation oi the parts, as will be presently more fully described.

Pivotally mounted upon the bolster, by means of a pin or bolt 13, adjacent to the latch stud is a trip lever or trigger 14, having a handle and also equipped with a sui ably disposed link or ring 16 for the attachment of a suit ably guided flexible element such as a chain, rope or wire by means of which the trigger may be actuated by the operator standing in any convenient position; only a short portion of the trip rope 17 has been shown, it being, however, understood that said trip rope may be extended to any conveniently accesible point. The trip lever or trigger is actuated in one direction by a spring 18, which may be constructed and arranged in any suitable and convenient manher; said trigger is provided with a recess 19 which is suitable shaped to engage the beak 20, of the latch hook 7, which latter, when in engagement with the late 1 stud 10, extends into the recess 19 of the trigger so that, by actuating said trigger against the tension of the spring 18, the latch hook may be thrown out of engagement with the latch stud, thus permitting the standard to drop to a nonobstructing position.

The standard A is preferably provided adjacent to its upper or outer extremity with an extension arm 0, hingedly connected therewith as by means of a bolt 21 said extension arm being provided'with a downward prejecting bracket 22, having a laterally extending lug 23, disposed adjacent to the outer edge of the stake or standard A. for the pur pose of maintaining the extension member 0 in an upri ht position as against strain exerted upon its inner edge it being obvious that said extension member, when not required for use, may be folded to a non-obstructing position adjacent to the standard A.

From the foregoing description taken in connection with the drawings hereto annexed, the operation and advantages of this form of the invention will be readily understood. It will be seen that when the stand ard is raised to an obstructing position approximately at right angles to the bolster, the latch hook 7 wfll be readily placed in engagement with the latch stud 10 and the trip lever or trigger 14, the upper edge of the brace arm 6, being in engagement with the guiding stud 11. T he standard will thus be securely supported and retained in an upright position for the purpose of retaining logs, lumber and the like that may be loaded up on the vehicle to which the standard is applied. In order to unload, it is only necessary to actuate the trigger 14 against the tension of the spring 18, thus causing the latch hook to be drawn out of engagement with the stud 10, and permitting the standard to drop to a non-obstructing position. This operation may be very readLly performed without the necessity of the operator exposing himself by standing in the path of the standard or of the logs as the latter are discharged from the wagon bed; a fruitful source of danger common to log and lumber carrying vehicles, and whereby many operators in the past have been hurt and maimed while unloading such vehicles, is thus dispensed with.

Under the modification illustrated in Fig. 4 of the drawings, it is proposed to dispense with the latch hook 7 and the latch stud 10; under this modification of brace arms, which is here designated 6 is provided at its free end with a head or enlargement 25, adapted to enter into engagement with a suitably shaped recess 26 in the trip lever or trigger, which is here designated 1 1 when thus engaged, the spring actuated trigger will hold the brace arm up against the guiding stud :11 and disengagement of the brace arm from the trigger is impossible until the trigger is tilted or actuated against the tension of its actuating spring, when the head of the brace arm will become disengaged from the recess 26, thus permitting the standard to drop to a non-obstructing position.

In Fig. 6, there has been illustrated a guiding means for the brace arm which consists of a lug or block 27 suitably connected with the brace arm upon the side or adjacent to the bolt, which latter is provided with :a slot or recess 28, for the purpose of guiding said lug or block; the latter is preferably connected pivotally with the brace arm by means of a pin or bolt 29. ltis obvious that under this construction, when the standard is raised to an obstructing position at rightangles to the bolster, the brace arm will be automatically guided to its proper position, enabling the latch hook to be very readily thrown intoeng'agement with the latch stud. Under the further modification illustrated in Fig. 7, the brace arm is provided with a loop or sleeve 30 guided upon the guide rod 31, which is suitably mounted upon'and slightly spaced from the bolster B.

Having thus described the invention, what is claimed is:

1. ii bolster having a latch stud and a guiding stud, a standard hingedly connected with the bolster, a brace arm hinged upon the standard and adapted to engage the guiding stud, and a latch hook pivotally connected with the brace arm and adapted to engage the latch stud.

3. A bolster, a standard hingedly connected thereby, a brace arm hinged upon the standard and carrying a pivoted latch hook, a stud upon the bolster adapted to be engaged by the latch hook and a spring actuated trigger pivoted upon the bolster and adapted for engagement with the latch hook.

4. A bolster, a standard hingedly connected therewith, a brace arm hinged upon the standard and carrying a pivoted latch hook, a guiding stud upon the bolster having a roller engaging the brace arm, a latch stud upon the bolster having a roller adapted to be engaged by the latch hook, and a spring actuated trigger pivoted upon the bolster and ada ted to engage the latch hook.

5. A olster, a standard hingedly connected therewith, a brace arm hinged upon the standard, a guiding stud upon the bolster engaging the brace arm and latching means for said brace arm including a spring actuated trip lever or trigger.

6. A' bolster, a standard hingedly connected therewith, and an extension member hingedly su ported adjacent to the outer eX- tremity of t e standard and having a bracket equipped with a laterally extending lug disposed in the path of the outer edge of the standard.

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

WVILMOT STRATHY.
