Application led January 21, 19,25.

To all fri/710m it may concern.'

Be it known that we, RAY W. BARRETT, a citizen of the United States, :i resident of the cit of I'luntington Beach, county of Orange, tate of California, and Liao T. KorPL, a citizen of the United States, a resident of the city of Huntington Beach, county of Orange, State of California, have invented new and useful Improvements in Elevators, of which the following is a specification.

This invention relates to an elevator and it is an object of the invention to provide an improved device of this character. I

It is an object of this invention to provide an improved locking device for an elevator'.

Another' object of this invention is to provide an elevator lock operable from the front or rear of theelevator.

A furtherobject of this invention is to provide an improved locking bolt for an elevator.

The various objects and 1features of our invention .will be best aiidIinore fully understood ifrom the following detailed descriptioiiof a typical forin and ,application of the invention throughout which description reference is had to the accompanying drawings ,in which Fig. vv1 is-a plan view of anvelevator einbodying the present invention, certain parts being broken away to show in section.

Fig. 2 is a plan section of tlieelevator `shovizing it applied to a pipe.

, position.

`The elevator' includes, generally, two main parts hinged or pivotally connected together to releasably engage around a rodpipe, oi'

`the lilie. the present case, one of these parts is in the form of a body 10 and the ,other is in the forni of a gate or closure Il for the body. In addition io the inain parts 1t) and 1l the elevator includes a locking ,bolt 12 for the closure, an operating ineinber 13 for the bolt and various other parts, the details v`and functions of which will be hereinafter set forth.

The body 10 in,the present forni of elevator has a vertical passage or opening 14 Aextending ,into it fi'oiii itsfroiitsidevto re Serial No. 3,754.

ceive the rod or pipe to be handled by the tool. The opening Vextends linwardly to about the center ofthe body where it terininates to forni a part adapted to more o r less accurately receive and hold the rod or pipe. It will be noted from inspection ofthe drawings that the inner end 15 of the opening v14 curved to conform to the curvature of the pipe P. The opening l14 divides ythe'front portion of the body into two spaced side parts A and B. The side parts A and B are provided with trunnions '17 to receive the usual supporting `hails (not shown).

'tllhe closure 11 is pivotally carried by one of the side ,parts of the bod this case, by the side part B sothat it isrnovalble'bevtween a position where it extends iacrossthe opening 14 to retain an object in the ,inner partofthe opening and aposition whereit is at or close to the side L1.4 and allows free passage of objects into l,andout of the inner part lof the opening. The closure v11 is nioiinted on the sidepart B ofthe Vbody by apivot pin 19 and is curved at its inner1 side 1S to conforii'i to the pipe P, or iiiother worlds, to forni a coiitiniilatioi'i of the curvatureof the inner part 15 of the opening 14. The onteiyeii'd of the side part issh'aped and proportionedto forni a stop 2O ,for the `closure toliiiiit the outward swingn'iovenient of the closure. The upperjface 21 of theA elo- Ysure isniiish with the top orupper fac-,e 22 of the. body so that the closure cooperates with the body iii supporting the load handledby tlieelevator. In this case, it is desirable to provide the outer en d of the closure with `projections24 which overlap a suitable part :25 of the sideA when the closure is in -closed position. Theclosure isprovided with an extension or trigger part 26 .which is located iii qa suitable recess 27 provided inthe wall of the opening when the closure is Vinclosed position and which projects into the opening 14 when the closure is open. The trigger part 26 is preferably `formed integrally with the closure y,and is shaped and proportioned to function or cooperate with theother parte yofthe device iii the manner hereinafter described. Tlie recess 27 is provided yto receive the trigger. part when the closure is iii closed position .and is formed laterally iinthe wall l.of the opening 14.

The bolt 12 provided for locking Athe closure. ,in closed position is slidably carried in,a.bo ia 3,0 provided ,at the `side part .A of, the body.

A spring 31 is yai'panged back of the bo-lt to normally yieldingly urge it outwardly in the opening 30 so that it overlaps and locks the closure 11 in the closed position and holds the trigger 26 in the open position. The spring 31 is arranged between the inner end of the bolt and a plug 32 provided in the bore 30. rl`he outer end ot the bolt is provided with a flat side adapted to engage the closure 11 in the manner clearly illustrated in Fig. 2 of the drawings. When the bolt engages the closure, as illustrated in Figs. 1 and 2 ot' the drawings, it operates to positively lock the closure to a closed position. W hen the closure is open the trigger part extends into the opening 14 of the body so that its outer end comes opposite the plunger and is engaged by the plunger as illustrated in Fig. 4. The bolt in engaging the trigger operates to yieldingly hold the closure in the ope-n position.

The operating member 13 for the bolt 12 is preferably in the form ot' a lever mounted in a recess 40 provided in the body. The recess 4U, in the preferred form of the invention, extends through the body from the iront to the rear. ln the case illustrated in the drawings the recess 4() is shown formed in the side part A of the body and extending inwardly from the opening 14 in the body. 'lhe recess 40 extends completely through the body from the front or outer end of part A to the rear of the body as clearly shown in Figs. 2 and 4 ot the drawings. The operating lever 41 is pivotally mounted in the recess 40 on a pivot pin 43 so that one of its ends forms a linger piece 44 operable from the rear ot the body while its other end forms a linger piece 45 operable from the front of the body. The

finger pieces

44 and 45 are preferably shaped and proportioned so that they are readily engageable, but so that they do not project from or beyond the body in a manner to be accidentally actuated by objects brushing against the elevator. ln accordance with the preferred forni olf our invention the operating lever 41 operates directly on the bolt 12. In the preferred form of construction the bolt 12 is mounted in the side part A so that it eX- tends through the recess 40. An opening 5() extends through the bolt 12 at the recess 40 and the lever 4] is arranged to extend through the opening 50. A. bearing part 5l in the forni ci a circular enlargement is provided on the lever 4l in the opening 5() so that the lever has the proper workingl lit with the holt. l/Vith this construction which is clearlyY illustrated in Figs. 2, 3, 4 and 5 of the drawings the lever 4l is con veniently operable from the front or the rear of the body to retract the bolt to release the closure.

In operation the elevator is applied to a pi e P, or the like` with the closure open as il ustrated in Fig. 4. As the pipe passes into the opening 14 it engages the trigger 26 to release it from the bolt 12 and to move it into the recess 27 in the body. This operation ot' the trigger causes the closure 11 to iollow the pipe i) into the opening 14 until the pipe reaches the inner end of the opening and the closure is in position where the beit automatically engages behind the closure to lock it closed as shown in F ig. 2. When it is desired to release the pipe from the elevator the lever 41 can be actuated by engaging either the linger piece 41 at the rear or' the body or the finger piece 45 at the iront o1 the body to retract the bolt to the postion shown in `nig. 5 thus releasing the closure and allowing the pipe to pass out ot the opening 14. As the pipe passes out of the opening 14 it moves the closure to the open position in engagement with the stop 20 and therefore causes the trigger part to assume its position in the opening 14 where it is engaged and yieldingly held by the bolt as shown by F ig. 4. It Will be noted that the locking device and operating means therefore, is particularly simple and inexpensive of construction and that it contains but a few simple parts. rlhe connection between the operating lever and bolt is particularly simple and efective. It Will be noted that this connection not only provides for proper operation of the bolt by the lever but also maintains the bolt in proper rotative position so that the flat part 33 at the outer end of the bolt is maintained in proper position to cooperate with the closure. Further, the provision of operating means for the bolt operable from the front or the rear is particularly important as it makes the elevator particularly convenient and fast to handle.
