STANDARD.

SPECIFICATION forming part of Letters Patent No. 758,089, dated A ril 26, 1904.

Application filed February 5, 1904. Serial No. 192,190- (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER M. MoYLAN, a citizen of the United States, residing at Gentury, in the county of Escambia and State of Florida, have invented certain new and useful Improvements in Standards, of which the fol' lowing is a specification.

This invention provides a peculiar construc-- tion of standardor stanchion to be attached to unloading of the vehicle.

the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description. and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferredembodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a front elevation showing the standard in working position, the dotted lines indicating the positions assumed by the standard and the locking parts when the standard is released in unloading the vehicle to which it is applied. Fig. 2 is a combined view in perspective of the lock-brace, lock-dog, and

standard, the latter being broken away. Fig.

3 is a view in elevation of a modified form of Fig. 4 IS a view in elevation means cooperating with the lock-brace. Fig.

'5 is a plan view, parts broken away, of the, -modified invention shown in Fig. 4:.

Corresponding and like parts are referred to in the following description and indicated in ail the views of the drawings by the same reference characters. f a 1 held in an upright position. stantially reinforce the engagement of the In the drawings the invention is shown applied tothe end portion'ofa car-bolster, though it will be understood that the standard is susceptible of use in connection with various classes of vehicles where a device of the class to which my invention relates could be used advantageously.

The standard comprises a body 1, which is provided at its upper end -with a chain-hook,

I sition, said brace 3 being provided at its lower end with a locking extension 12, which engages the lower end of the arm 2 of the standard to rigidly hold the standard in the po- In order to hold the lockbrace -3' in the engaging position above described, the lock member or dog5 is utilized, which member 5 is pivoted to the pivotal member 7, upon which the standard is mounted. The lock-dog 5 is provided with the lug 6, which engages a projection extended laterally from the upper end of the brace 3. Since the lock-brace 3 when attached to the support is mounted in about the same plane of movement as the arm 2 of the standard, it is necessary to provide the projection 4. or some equivalent means with which the dog 5 is adapted to engage.

It will be noted that when the brace 3 is in the engaging position (indicated in Fig. 1)

and locked by dog 5 the standard 1 is firmly To more subparts above mentioned, the arm 2 of the standard is provided upon its rear side with a rib 'sition clearly shown in full lines in Fig. 1.

.or tongue 10, and the portion of the brace 3- lines in Fig. 1.

which comes into contact with the rear side of the arm 2 is likewise provided with a matching tongue or, groove 8, which receives the rib 10, establishing an interlocking connection throughout the length of the parts 2 and 3, which reinforces the parts in a manner which will be appreciated. With a view to further reinforce the interlocking connection of the parts the projection 4 of the brace 3 is provided upon its upper side with spaced lugs 9, between Which the lock-dog 5 is received when the latter engages the brace. The pin 11 is projected from the support to which the standard is attached, and this pin normally supports the lock-dog, the outer end of which rests upon the pin in a position readily admitting of the engagement of the said dog 5 with the brace 3. The end portion of the dog 5 which rests upon the pin 11 is the portion which is lifted or tripped in effecting the movement of the standard 1 in unloading.

, When the dog 5 is moved upwardly, the lug 6 disengages from the upper end of'the brace 3, and'the weight of the load instantly throws the standard in the position shown in dotted The downward movement of the dog 5 is of course limited by the pin 11. The arrangement or disposal of the parts of the device upon the bolster or support adunits of tripping thedog 5 without danger to the operator, and this is of no small importance in that a great number of accidents are caused by falling of a part of the load upon the one who displaces the stanchion or standard. Further, the parts of the device are always in working position and ready to be operatedwhenever desired.

In Fig. 3 a slightly-modified form of lockbrace 3 is shown. This part supports the standard in the same manner as that illustrated in Fig. 1, but does not have the extension 12, which interlocks with the arm 2 of the standard, as described in the preferred form of the invention. The cooperation between the dog 5. and the part in Fig. 3 and the general mounting of the parts in this construction are substantially the same as that in the preferred form shown in Figs. 1 and 2.

It is contemplated to make certain detail changes in the manner of mounting the parts and the construction of the members consistent with the spirit of the invention as found necessary in the practical embodiment thereof.

.In certain instances it is desirable to dispose the standard centrally upon the end portions of the bolster, as shown in Fig. 4., In order to position the standard as above indicated without cutting a very large portion of the bolster away, thereby impairing the strength of the bolster, the lock device is in the form of a clevis 15, which embraces the standard upon opposite sides, being pivoted to the pivot of the standard 1 in like. manner as the dog is pivoted in thepreferred form of the invention. The clevis is adapted to engage the upper end of the lock-brace, as clearly illustrated in Fig. 5. From the foregoing it will be seen that the operating parts of the standtripping of the clevis 15 to displace the stand ard from its upright position. The arm 2 of the standard is provided with a notch 17 which is engaged by the clevis or look device 15 on dropping of the standard, as will be clear by reference to Fig. 4. .The standard is thus utilized to hold the clevis in a position adapting same to be readily adjusted in looking engagement with the lock-brace 3.

Having thus described the invention, what is claimed as new is 1. The combination with a support, a standard pivoted between its ends to the support, a lock brace engaging the lower end of the standard, and means for locking the lock-brace in the engagement aforesaid.

2. The combination With a support, astandard pivoted between its ends to the support, a lock-brace engaging the. lower end of the standard, and a lock-dog engaging the lockbrace.

3. The combination With a support, a standard pivoted between its ends to the support, a pivoted lock-brace interlocking with the lower end of the standard, and a pivoted lock member engaging the lock-brace.

4, The combination with a support, a standard pivoted at its lower portion to the support, an arm projected from the standard at the point of pivotal support thereof, a lock-brace engaging the arm of the standard, and a lock member carried by the support and engaging the lockbrace to hold the said brace in engagement with the standard.

5. The combination with a support, a standard pivoted to the support at its lower portion and having its lower end extended to form an arm, a lock-brace pivoted adjacent its lower end to the support, an engaging extension projected from the lock-brace into engagement with the arm of the standard, and a lock-dog mounted upon the pivotal support of the standard and engaging the upper end of the lock-brace.

6. The combination with a support, a standard pivoted to the support, a lock-brace en-- gaging said standard, a lock-dog engaging the lock-brace, and a tongue-and-groove connection between the meeting or engaging portions of thelock-brace and standard.

7. The combination with a support, a standard pivoted at its lower portion and having its lower end extended downwardly to form an arm, a lock-brace pivoted adjacent the stand- In testimony whereof I afiix my signature in ard andengaging the arm thereof, a lock-dog preseneeof two witnesses. mounted upon the pivotal support of the standard and engaging the lock-brace, and a tongueand-groove connection between the meeting or engaging portions of the lock-brace and the arm of the standard.
