HENRY ALINDER, OF MILWAUKEE, WISCONSIN, AF SSIGNOR TO ALLIS-CIIALMERS MANU- FACTURING COMPANY, OF MILW'AUKEE, WISCONSIN, A CORPORATION OF DELA- WARE.

LOCKING DEVICE.

Application filed November 29, 1915.

To all whom it may concern:

Be it known that I, HENRY ALINDER, a subject of the King of Sweden, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Looking Devices, of which the following is a specification.

This invention relates to improvements in the construction of devices for detachably securing and locking two elements to each other, the invention being particularly applicable to timber treating apparatus.

An object of the invention is to provide a locking device which is simple in construction and effective in operation. Another object is to provide a device for detachably securing two elements to each other, which will permit ready separation of the elements when desired.

The invention consists primarily in forming one of the elements to be connected with a recess affording a plurality of abutments, and of providing the other element with a shoulder engageable with one of the abutments to prevent separation of the elements in one direction, separation of the elements in another direction being prevented by means of a third element engageable with another of the abutments. While the invention is especially applicable to devices for locking the bails of timber treating cars to the bail arms or other elements, it is capable of general application wherever similar conditions of ope ation eXist.

A. clear conception of an embodiment of the invention may be had by referring to the drawing accompanying and forming a part of this specification in which like reference characters designate the same or similar parts in the various views.

Figure 1 is an end view of a timber treating car having the invention applied theretomv Fig. 2 is an enlarged transverse section through the locking device showing the same applied to a fragment of a timber treating bail, the section being taken along the line IIH of Fig. 3 looking toward the right.

Fig. 3 is an enlarged end view of the looking device showing the same applied to a fragment of a timber treating bail.

Fig. 4 is an enlarged top view of the portion of the locking device which is normally secured to the bail arm.

Specification of Letters Patent.

Patented Apr. 3, 1917..

Serial No. 64,590.

Fig. 5 is an enlarged top view of the lock- 1ng plate.

The timber treating oar disclosed in Fig. 1 consists primarily of a body portion 1 having upwardly extending integral bail arms 2, and supported upon wheels 3 in the usual manner. Each bail comprises essenti ally two sections 5 having looped interlocking upper ends 6, 16, and having headed or enlarged lower ends 8. The portion of the car within the bail arms 2 and the bail sections 5 is, during normal operation of the device, filled with timber which is prevented from leaving the car during the process of treating, by means of these elements.

Each of the devices for detachably securing the elements, namely, the bail sections 5 and the bail arms 2, together, comprises an element 4 integrally secured to the adjacent bail arm 2 by means of rivets 9 passing through alined openings in the bail arm 2 and the projection 10 of the element 4:. The element 4: is provided with a recess 13 having a lower enlarged portion 15 afl'ording an abutment and having a second enlarged portion 14 affording a second .butment. The enlarged or headed end 8 of the adjacent bail section 5 is insertible. within the recess 13 so that the shoulder formed by the enlargement of the end of the section 5 is engageable with the abutment in the recess 13 formed by the enlargement 15 thereof. This formation. of the bailsection 5 and of the recess 13 positively prevents separation of the elements in one direction, namely, axially of the bail section 5.

A locking plate 7 having its upper portion 11 split at 12 to permit placing the same around the bail section 5, has a downwardly extendingportion adapted to enter the enlarged portion 14 of the recess 13. With the'locking plate 7 inserted as disclosed in Figs. 2 and 3, the longitudinal edges of the plate engage the second abutment of the recess 13 afforded by the enlarged portion 14: thereof to prevent separation of the bail section 5 and the bail arm 2 in another direction, namely, transversely of the axis of the section 5.

In securing a bail section 5 to its bail arm 2, the locking plate 7 must first be raised to a position permitting insertion of the headed end 8 within the recess portion 15. After the bail section 5 has been placed in the position disclosed in Fig. 2, the looking plate 7 may be inserted in the recess portion 1a and lowered until stopped by the headed bail end 8, thereby positively look- 'ing the bail section 5 against displacement from within the element 4:- The bail section 5 may be readily removed by' raising the locking plate 7 and swinging the headed bail end 8 clear of theelement 4 about its upper end 6, 16, as a pivot. The formation of the bail of two sections 5 connected at their upper ends 6, l6, permits either simultaneous or successive connection of the headed bail ends 8 to their respective bail arms 2. The separation of the elements may like wise be simultaneous or successive, as desired.

It will thus be noted that the formation of the recess 13' and the engagement of the locking plate 7 andheaded end 8 with surfaces of said recess, aifords simple and eflicient means for securing the bail to the bail arm 2 and of readily releasing these elements for separation. g

It will also be noted that the locking plate 7 cooperating with the abutment afiorded by the recess portion 14, affords a second abutment located forwardly of the end of the bail section 5 with reference to the displacement of the bail section 5 relative to the element 4 in a direction transversely of the axis of the bail section 5. It should be understood that it is not desired to be limited to the exact details of construction herein shown and described, for obvious modifications may occur to a person skilled in the art.

It is claimed and desired to secure by Letters Patent,- a

1. In combination, an element having a recess afl'ording an abutment, a second element insertible in said recess and having a shoulder engageable with said abutment to prevent separation of said elements in one direction, said recess affording a second 7 abutment, and means secured to said second element and engageable with said second abutment to prevent separation of said elements in another direction. 7

2. In combination, an element having a recess enlarged at one portion to form an abutment, a second element insertible in said recess and having an enlarged portion engageable with said abutment to prevent separation of said elements in one direction, said recess having a second enlarged portion affording a second abutment, and means engageable with said second abutment to prevent separation of said elements in another direction.

3. In combination, an element having a recess affording an abutment, a second element insertible in said recess and having a shoulder engageable with said abutment to prevent separation of said elements in one direction, and means secured to said second element and affording a second abutment located forwardly of said second element wit-h reference to another direction in which separation of said elements is prevented.

4. In combination, an clementv having a recess provided with a plurality of enlarged portions extending at an angle to each other, a second element having an enlarged portion insertible within one of said enlarged recess portions, and means insertible in the other of said enlarged recess portions to lock said elements against relative movement.

5. In combination, an element having a. recess provided with a pair of enlarged portions extending at an angle to each other, a second element having an enlarged end insertible within one of said enlarged recess portions, and a locking plate having a portion surrounding said second element, said locking plate being insertible in the other of said enlarged recess portions to lock said elements against relative movement.

6. In combination, an element having a recess provided with a pair of enlarged portions extending at an angle to each other, a second element having an enlarged end insertible within one of said enlarged recess portions, and a locking plate insertible in the other of said enlarged recess portions and engageable with a portion of said second element beyond said enlarged end to lock said elements against relative movement.

In testimony whereof, the signature of the inventor is afliXed hereto.
