UNITED STATES PATENT OFFICE.
CLYDE KNISLEY, OF HUNTINGTON BEACH, CALIFORNIA.
ELEVATOR.
Application led January 30, 1925. Serial No. 51,758.
To all whom t may concern.'
Be it known that I, CLYDE KNIsLnY, a citizen of the United States, residing at Huntington Beach, in the county of Orange and State of California, have invented new and useful Improvements in Elevators, of which the following is a specification.
This invention relates to improvements in elevators used in raising and lowering drill pipe and the like in well drilling operations.
It is an object of the invention to provide an improved elevatorv having a body upon which there is a swinging or hinged door; to provide an improved latch construction for locking the door in closed position; and to provide means whereby when the handle is pulled so as to open the door, the latch will be simultaneously thrown into released or opening position.
A further object of the invention is to provide an elevator havin a body and a hinged door; and to provide a trigger device adapted to be engaged by a portion of the door u on being swung open, so that the door may lie temporarily heldin open posiltion. The trigger device is so arranged that when the body is placed about or'caused to engage a section of drill pipe, the trigger device will release the door and enable it to be automatically swung into closed position.
lVith the foregoing and other objects in view which will be made 'manifest in the following detailed description and pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, where- 1n:
Figure 1 is a top plan view of the improved elevator, arts `being broken away and shown in horizontal section;
Fig 2 is a vertical section through the handle of the door ofthe elevator and is taken substantially on the line 2--2 of Fig. l; Fig 3 is a front elevation of the elevator,
the door being shown in closed position;
Fig. 4 is a detail in elevation taken-sub.-
lstantially in the direction ofthe arrow 4 up on Fig. 1; and
Fig. 5 is a front elevation showing the improved elevator in applied position.
Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, theim roved elevator consists of a semi-,cylindriea body 10, which has formed upon its opposite ends per and lower lips 20.
-A door 16 is hinged to the body 10 by means of a pin or rivet 17. As clearly shown in Fig. 1, the interior surface of the body v10 is tangential to the circular part, as indicated at 18, opposite the swinging end of the door 16, and the door 16 is provided with i a lip 19 fitting in the recess provided by the tangential surface 18 and the pipe P. From the front face of the body 10 there' extend lugs or lips 20 and the swinging end of the door 16 is adapted to slide between the up- This swingingend hasformed thereon a handle 21.
A' latch member 22 is slidable in a bore 23 formed in the top of the handle and this latch member has formed thereon an annular flange 24, against which bears the upper end of a coil spring 25. The lower end of the coil spring 25 is kept in proper osition upon the handle 21 by means of) a pin 26. Ears 27 are formed upon the handle, and an angular lever 28 is pivoted between these ears as indicated at 29. The upper end of the latch member 22 is adapted to occupy a recess 30' formed upon the under side of the upper lug 20. Preferably the u per end of the latch member 22 is provi ed with an inclined surface 31 to facilitate forcing the' latch member 22 downwardly within the handle upon engagement with the forward surface of the upper lug 20, enabling the door to be slammed or` thrown shut. The
The operation of the elevator is as follows: Upon placing the hand upon the handle 21 and giving an outward pull to the handle, the angular lever 28 will be actuated so as to retract the latch member from the recess 30, enabling the door to be opened. The door may then be swung open and when being moved into full open position, the hooked end 39 of the lever 37 will move into the aperture 85 in the finger 34. The pipe P may then be withdrawn from the body, and as the coil spring 42 bears upon the lever 37,' the hooked end 39 will be maintained in engagement with the edge 39a upon the linger 34. In this manner the door 16 may be temporarily held in open position against the action of the spring 44. l/Vhen the body 10 is swung into engagement with the pipe P So as to cause the engaging portion 40 of the lever 37 to contact with it, and to be forced backwardly against the action of the coil spring 41, the hooked end 39 of the lever 37 will disengage from the edge 39a, and enable the door 16 to be swung into closed position by the coil spring 44. Upon the front face of the door 16, there is mount ed a hook 45 and the end of the spring 44 which bears against the lower lug 12, can be swung over against the front Jface of the door 16 and placed beneath the hook 45. In this manner, the door will be allowed to swing freely without being under the `action of the spring 44, if so desired.
It will be understood that various changes in the detail of construction ma be made without departing from the spirit or scope of the invention as defined by the appended claims.
I claim:
1. An elevator for drill pipe and the like having a body and asu/inging door, a trigger mounted upon said body, means associatedl with said door adapted to be engaged by said trigger upon swinging the door open, whereby said door may be temporarily maintained in open position by said tr' ger, 'and door closing means urging said oor into closed position, said trigger being so arranged that contact with a pipe or similar object will release said door lso as to be closed by said door closing means.
2. An elevator for drill pipe and the like having a body and a swinging door hinged thereto, a trigger device mounted within said body, a finger provided upon said door adapted to engage said trigger device upon swinging the door into open position, whereby said door may be temporarily held in open position byl said trigger device, and spring means for urging said door into closed position, said trigger device being yso arranged that engagement of said body about a drill pipe or the like will actuate it so as to release said door. v
3. An elevator for drill pipe and the like comprising a body, a door hinged to said body, spring means for normallv urging said door into closed position, holding means adapted to temporarily hold said door when swung into open osition, and means for releasing said holding means, said door being provided with a spring actuated latch adapted to lock said door in closed position.
4. An elevator for drill pipe and thelike comprising a body, a door hinged to the body, a handle upon said door, a latch mounted upon said handle, means associated with said latch and mounted u on said handle, whereby an opening pu l npon said handle will cause said latch to release, and means urging said door into closed position.
5. An elevator for drill pi e and the like comprising a body, a door inged to said body, a handle upon the door, a latch engageable upon the handle adapted to engage Said body to lock the door in closed position, spring means for urging the latch into locking position, and a pivoted lever mounted upon said handle for moving the latch into releasing position.
In testimony whereof Ihave signed my name to this specification,
o. itinerant.`
