Application November 9, 1936, Serial No. 110,006 4 Claims. (Cl. 294-90) The present invention relates to new and useful improvements in elevators for oil or gas well rigs or derricks and has for its primary object to the guides 0 to 8, inclusive. Formed integrally with the upper end of the guide 6 is an apertured ear llv in which a lifting ring I2 is loosely provide, in a manner as hereinafter set forth, a mounted. . 5, device of this character embodying novel means , Ears l3 project from the guides ‘l and 8, as for automatically centering the pipe in the well casing while at the same time ?rmly securing said pipe. Another very important object of the inven shown to advantage in Figure 1 of the draw ings, said ears having openings therein for registry tion is to provide an elevator of the aforemen tioned character comprising a pair of hingedly connected complemental sections together with novel means for releasably securing said sections in closed position around the pipe. 15 Other objects of the invention are to provide an elevator of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, com~ pact, light in weight and which may be manu factured at low cost. , All of the foregoing and still further objects and advantages of the invention will become ap parent from a study of the following speci?cation, taken in connection with the accompanying draw ings wherein like characters of reference desig nate corresponding parts throughout the several views, and wherein: Figure 1 is a view in front elevation of an elevator constructed in accordance with the pres ent invention. Figure 2 is a view in side elevation thereof. Figure 3 is a top plan view. Figure 4 is a fragmentary View in vertical sec tion, taken substantially on the line 4—4 of Figure 1. Figure 5 is a fragmentary view in rear eleva tion of the device. Referring now to the drawings in detail, it will be seen that the embodiment of the invention 40 which has been illustrated comprises a metallic ring which is designated generally by the refer ence numeral I, said ring including a pair of complemental half sections 2 and 3 which are hingedly connected at one end, as at 4. Pro 45 jecting from diametrically opposite sides of the ring I are tapered guides 5, A tapered guide 6 projects from the hingedend of the ring section 2 adjacent the hinge 4,_while tapered guides 1 with each other when the ring sections 2 and 3 are closed. The latch I0 includes a vertical cylinder M in which a bolt I5 is slidably mounted. A collar 10 IB is provided on the lower portion of the bolt [5 in the cylinder M for engagement by a coil spring I‘! for yieldingly urging said bolt downwardly. As best seen in Figure 4 of the drawings, the lower end portion of the bolt I5 is engageable in 15 the registering openings of the ears l3 for re leasably locking the ring sections 2 and 3 in closed position. The latch I0 further includes a lifting plate l8 for the bolt 15 which is secured on the upper 20 end portion of said bolt. The lifting plate l8 comprises an upstanding integral neck [9 in which the bolt I5 is secured by a pin 20. It is thought that the manner of using the de vice will be readily apparent from a considera 25 tion of the foregoing, particularly to those skilled in the art to which said device pertains. A hoist line (not shown) is attached to the ring l2 and the ring sections 2 and 3 are closed around the section of the pipe to be raised or lowered in the 30 well between the coupling or joint of the pipe. The device is, of course, secured in closed posi tion by the latch I0. The tapered guides 5 to B, inclusive, engage the walls of the well casing in a manner to automatically center the pipe therein. 35 When the bolt I5 is in lowered or locking position the lifting plate 18 is engaged between the guides 'l and 8 in a manner to be protected thereby, thus preventing said plate from being accidentally ele vated and unlocking the device. In order to open 40 the ring sections 2 and 3 for releasing the pipes the bolt I5 is raised and the bolt 15 may be held in raised position against the tension of the coil spring IT by swinging the lifting plate [8 over the upper end of the guide 8. The reference numeral 2| designates a suitable ?tting for lubricating the latch l0. Hand holds in the form of open rims 22 connect the upper portions of the guides of the ring sections 2 and 3 in spaced relation from said ring sections to facilitate plac and 8 are provided on the free end portions of the 50 ring sections 2 and 3. It will be observed that the guide 8 is spaced from the free end of the ing said ring sections around the pipe. ring section 3, thus providing a chamber 9 for the reception of a latch which is designated gener ally by the reference numeral lll. It will also be 55 observed that the side ‘guides 5 are wider than It is believed that the many advantages of an elevator constructed in accordance with the pres ent invention will be readily understood, and al though a preferred embodiment of the device is as 2 2,122,513 illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed. What is claimed is:— 1. An elevator or" the class described compris ing a ring including a pair of complemental half sections hingedly connected at one end, means for 10 releasably securing the rings together in closed position around a pipe, tapered guides projecting from the ring forlcentering the pipe in the well casing of a well, and a rim connecting the upper free end portions of the ring sections and being spaced from each other chamber therebetween, a manner to de?ne a ears on said ' certain guides having openings therein for registry with each other when the ring sections are in closed position around a pipe section, and a latch mount ed on one of said certain guides and engageable in the ears for releasably locking the ring sec tions in closed position, said latch including a cylinder, a‘spxgingactuated bolt mounted for ver 10 tical reciprocation in said cylinder, and a lifting plate mounted on the upper end portion of said bolt, said lifting plate being engaged in the ' portions of the guides in spaced relation to the chamber when the bolt is in operative position ring sections, said rim constituting a hand grip. and being engag‘eable on said one of said certain 2.
