JOURNAL-BOX.

Specification of Letters Patent.

Patented Dec. I9I5.

Application filed April 4, 1911. Serial No; 618,821.

T 0 all whom it may concern:

Be it known that 1, MICHAEL J. SAssEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Journal-Boxes, of which the following is a specification.

The present invention relates to a journal box more especially adapted for use as a mounting for shafting, trunnions, and anal ogous bodies.

The objects of the present invention are, to provide a journal mounting which Will be strong and durable and well adapted to withstand the strain of usage, and Which will permit of the positioning and removal of the mounted shafting without the necessity of removing the entire journal mounting from the structure.

A further object of the invention is to provide a journaled mounting which will permit the fastening means for securing the body portion of the journal bearing to remain in place continually during the use of the journal, and which will provide a removable member to permit of the removal of the mounted shafting from the body of the journal, which member will be secured by means independent of the means for securing the body portion of the journal mounting in position, so that the removal and positioning of said member does not affect the rigidity of the secura nce of the body of the journal.

A still further object of the invention is to so arrange the parts that the strain in usage will come upon the body of the journal.

The invention further consists in the features of construction and the combination of parts hereinafter described and claimed.

In the drawings. Figure 1 is a cross section of the mounting of the present invention; Fig. 2, a side elevation; and Fig. 3, a plan view.

In the use of journal boxes. especiallv on derriclcs and analogous structures. it is frequently desirable to loosen the trunnions or other members held in the journal for the purpose of removing the drum or analogous members. In the journals ord narily employed in such constructions, so far as I am aware. it has been a matter of difiicultv to remove the trunnion or other mounted shafting without removing the entire journal from the body of the structure. This, of

course, is undesirable, since it means more or less bother and Work in disassembling and reassembling the body of the journal.

The present invention consists of what may be termed a base plate I, Which is attached to the body of the structure to which the journal is secured, by means of suitable fastening members passing through openmgs 5; or the securance may be effected in any other suitable manner. The base plate has extending therefrom a series of lugs 6, which, as shown, are extending at an angle to the base plate and projecting ioutwardly therefrom to form a channel 7, terminating in a configured seating-face 8, Which,in the construction shown, is semi-circular. This angled formation is for the purpose of providing a sufficiently deep channel without extending the lugs too far out from the base plate so that they would be liable to be hit and broken during usage.

The channel 7 has mounted therein a block 9, which terminates in a configured face 10, which, in conjunction with the face 8, forms the entire seat for the to-be-mounted shaft ing. The block 10 is held in position by means of a threaded bolt 11. By this arrangement, the operation of removing the member from the journal bearing is extremely simple, all that is required being the unfastening of the bolt 11 and the slipping out of the block 9. The securing members for the body of the journal, as will be evident, need not be disturbed during this operation.

In the operation of derricks, pulleys, and analogous devices, the strain upon the bearings is usually in one direction. By arranging this journal so that the strain will come against the inner end of the journal box, which, in the construction shown. is the base plate 4. there will be little or no strain placed upon the block 9, or upon the lugs 6, and hence the journal will be adapted to withstand the strain and wear of usage.

It is understood that in the spec fication and claim where the word shafting is used, it is meant to cover shafts, trunnions, and other analogous devices which are usually placed in a journal mounting, whether they be rotatable or non-rotatable. To simplify the terming of the parts in the claim. the terms fixed and movable have been emploved. Bv the fixed section is meant that portion secured to the structure,

and by the term movable is meant that part Which is removed to permit the removal of the shafting.

I claim: 7 a

A ournal bearing comprising a fixed section of unitary formation, consisting of a base member composed of a fiat-like surface adapted to be secured to a structure, and provided with lugs extending therefrom at an angle thereto, and forming a U-shaped slot terminating in a semi-circular face, the

straight lines of the slot beingspaced apart Copies of this patent may be obtained for ing in the block, a locking member adapted to be inserted through said openings, said block when locked in place having the upper edges of its curved portion terminating below the curved portion of the slot and producing an oblong opening in the bearing,

whereby the shaft when resting against the face of the curved portion of the base lTlGlll-i ber lies free from engagement with the face of said block, and the metal at the juncture of the inner and side faces of the block being drawn to an edge Wnereby no abrupt breaks are afi'orded in the walls of the openings.
