JOURNAL-BOX.

Specification of Letters Patent.

Application filed July 21, 1908.

Patented Oct. 31, 1911. Serial No. 444,606.

To all whom it may concern.- I

Be it known that I, CHARLES F. MURRAY, a citizen of the United States, and a resident of Chicago, Oook county, Illinois, have invented certain new and useful Improvements in Journal-Boxes, of which the following is a specification.

This invention relates to car truck journal boxes and has particular reference to the means for securing and operating the lid or cover for the said box.

One of the advantages which is sought to be attained by the present invention is the complete inclosure of the operating springs for the journal box lid. The main objection to the lids and operating means now in use is the fact that they are liable to become broken or lost, because of arduous operation conditions, particularly when exposed to the weather in any way, or when placed on the interior of the lid their temper is destroyed by the overheating of the box, which is liable to occur at intervals. Another advantage sought to be obtained by my invention is the provision of a box which shall admit of its interchange with any M. O. B. lid. This is desirable, because lids are frequently broken in service and unless they can be repaired promptly must necessarily remain open until the terminal is reached, the journal in the mean time collecting large amounts of dust and grit.

My invention will be more readily under stood by reference to the accompanying drawings forming a part of this specification and in which;

Figure 1 is a front elevation partly in section; Fig. 2 is a sideelevation in section on line 22 of Fig. 1; Fig. 3 is a horizontal section on line 3-3 of Fig. 1; Fig. l is a perspective of a fragment of the lid showing its cam surface; Fig. 5 is a fragmentary view of the cooperating cam parts of the lid and journal box lugs; and Fig. 6 is a perspective view of the follower ring.

Referring more particularly to the drawings, A, is the journal box and B is the lid. The journal box is provided with an upstanding lug, 6, having an aperture therein, one end, 7, of which is contracted to the size of the bolt, the main portion, 8, is slightly enlarged and an outer portion, 9, is still further enlarged. Within the main opening, 8, I place a spring, 10, which is retained in place by means of a ferrule or ring, 11,

which is circular in form. On the side of the upstanding lug, 6, I form a cam surface as at 12. The lid, B, has the usual upstanding portions, 1313, each having an aperture for the passage of the retaining bolt. On the inner face of one of the upstanding portions, 13, I provide a cam surface as at 1% for coiiperation with cam, 12, upon the journal box lug. Upon the interior of the lid and adapted to fit closely within the opening in the journal box, I provide a flange, 15, and a flange, 16, is adapted to fit outside of the opening in the journal box. A bolt or rivet, 17, holds the lid and parts in operative connection to the journal box lug.

The parts are assembled as follows: The spring, 10, is placed in the opening, 8, and is followed by the ring, 11. The lid is then forced thereon, the part next to the ring being first placed and the spring compressed, the lid meanwhile being held in a vertical position to a point where the cam openings are co-incident. After the lid is located the rivet, 17, is placed and headed and lid swung into closed position.

In operation, upon lifting the lid, the cams force the lid sidewise, compressing the spring, 10. As the lifting motion is continued, the cam surfaces will ride upon flat portions in order that the lid may be sustained at any desired location. Upon returning the lid toward the closed position the spring behind the cam will return the lid sharply to its position over the journal box opening.

To adapt any M. O. B. lid to this journal box, it would be necessary only to remove the spring, then return the ring 11 to the opening, 9, the aperture of the ring for the passage of fastening bolt being of the standard size.

To prevent spilling of the oil upon movement of the box in service, I provide a ledge, 18, standing out from the opening in the inside of the box.

It will be noted that inasmuch as the bolt fits tightly in the opening, 7 and as the part, 11, fits closely within the opening, 9, that the spring is completely protected from the elements at all times.

As various modifications of my invention will readily suggest themselves to one skilled in the art, I do not confine my invention to the specific constructions herein shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A journal box provided with an upstanding lug having a cam surface and an aperture therethrough of varying transverse dimensions, a spring within said aperture, a follower, in combination with a lid having a cam surface adapted to cooperate with the cam surface of said box lug, a pivot rod or pintle extended through the aperture of said box lug, and on which said lid is adapted to turn, said spring bearing at one end against the shoulder of said aperture at the junction of portions of different dimensions and also against the follower to press the same against the lid and maintain said cam surfaces in operative engagement.

2. A journal box provided with an upstanding lug having a cam surface at one end and an aperture therethrough of varying dimensions, a spring within said aperture, a follower in said aperture at the end of the lug remote from said cam surface, in combination with the lid having a pair of lugs, one of which has a cam surface cooperating with the cam surface of the box lug, and a pivot rod or pintle extended through the aperture of said box lug and apertures of said lid lugs, and on which said lid is adapted to turn, said spring bearing at one end against the shoulder of said box lug aperture at the junction of portions of different dimensions and also against the follower to press the same against the lid lug not supplied with the cam whereby to maintain said cam surfaces in operative engagement.

In testimony whereof, I have hereunto set my hand this 17 day of July, 1908, in the presence of two subscribing witnesses.
