GEORGE A. WOODMAN, OF CHICAGO, ILLINOIS.

JOURNAL-BOX.

- Specification of Iietters Patent.

Patented July 2, 1907.

Application filed April 27,1906. Serial No. 313,981.

To all whom it may concern:

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

The object of this invention is to improve the journal box covered by my Patent No. 799,365 dated Sept. 12, 1905 and by my allowed application No. 272,468 filed August 3, 1905, whereby the construction of parts is simplified and the cost of manufacture is reduced and whereby also results 'of a superior character are obtained. v

In the accompanying drawings illustrating one embodiment of the invention Figure 1 is a front View of a box showing the lid in open position. Fig. 2 is a sectional view on the line 2,2 of Fig. 3. Fig. 3 is a vertical sectional view showing the lid closed. Fig.4 is a detail end view showing the pintle and its locking nut. Fig. 5 is a sectional view on the line 55 of Fig. 3. Fig. 6 is a perspective view of one end of the box lug showing the cam surface thereon. Fig. 7 is a detail view of the locking cap.

Referring to the drawings 10 designates a journal box which is provided with a lug 11 bored to receive a pintle 12 which hinges the lid 13 to the box. The lid has sleeves 14, 15 to receive the pintle and between them is a hood 16 which partly covers the box lug.

A projection 17 on the inner end of the sleeve 14 (Fig. 1) is arranged to travel on a cam surface on the adjacent end of the box lug (Fig. 6) and this cam surface comprises

depressions

18, 18 with an intermediate elevation 18. When the lid is closed the projection 17 will lie in the depression 18 and when the lid is open the projection will lie in the depression 18, and in moving from one position to the other the projection will travel over the elevation 18 The sleeves on the lid are spaced apart sufficiently to permit a limited sidewise play of the lid relative to the box lug and an expansion spring 19 is arranged on the pintle within the sleeve 15 and bears against and has one end made fast to the box lug and the other end made fast to the lid. This spring operates to hold the projection 17 in one or the other of said depressions in the box lug and thereby temporarily locks the lid in open or closed position, The spring also operates to automatically throw the lid to open or closed position after the lid has been moved by hand to carry the projection 17 over the highest point of the elevation 18. A cap 20 (Fig. 7) is held in place on the end of the pintle by a cotter pin 21 and thiscap has a polygonal head 22 which makes locking engagement with a lip 23 on the lid. This cap is provided with a slot 24 in its side to receive the outer end 25 of the spring which is bent inwardly to enter the cap through said 'slot and make locking engagement with the cap. The

inner end 26 of the spring is arranged in a slot 26 in the box lug (Fig. 4, Fig. 5). By this construction the spring is locked at one end to the lid and at its other end to the box and hence the spring will be stretched torsionally when the lid is opened and this torsional strain of the spring will cause the lid to close automatically and ,quickly after the projection 17 has passed the high point of the elevation 18.

When it is desired to tighten or loosen the spring the cotter pin 21 is removed and the cap pulled out on the pintle until its head clears the lip 23, whereupon the cap can be turned either way and without releasing the outer end of the spring. After the adjustment has been made the cap is forced back into place with its head in engagement with the lip. Thus the tension of the spring may be adjusted by turning the cap without at any time disengaging the cap from the spring. The lid is made to fit tightly against its seat formed by the edges of the box surrounding the opening-27 so that dirt may not enter 'the box and oil may not escape therefrom. The outer face of the side edge 28, the inner face of the lower edge 29, the inner face of the upper edge 30 and the outer face of the side edge 31 are beveled. These edges are broad and fiat, the side edges being broader than the top and bottom edges, to make a solid and effective contact surface. The lid is provided on its under side with a channel 33 to receive the edges of the box and this channel is formed by parallel ribs on the inner face of the lid. The inner face of the side ribs 34, 35 (Fig. 2) and the bottom rib 36, and the outer face of the top rib 37 are beveled (Fig. 3) to fit the correspondingly beveled faces of the edges of the box. The inner side ribs 34 35 (Fig. 2) are tapered; the outer face of the inner rib 37 is beveled to fit the beveled inner face 30 of the top edge of the box (Fig. 3); the inner bottom rib 36 projects inwardly beyond the lower edge 29 of the box when the lid is closed to permit oil to flow down thereover into the box without working out between the box and the lower edge 29.

The improvements herein described provide for assembling the parts in a simple manner and for easily adjusting the spring and also making a tight joint between the lid and edges of the box to prevent the entrance of dirt into the box and the escape of oil from the box. The spring can be adjusted to high tension so that it will hold the lid firmly in open or closed position after the projection 17 has passed the high point of the elevation 18.

What I claim and desire to secure by Letters Patent 1. The combination of a journal box having a lug thereon provided at one end with a cam surface, a lid, a pintle pivotally connecting the lid to said lug, there being a projection on said lid to travel on said cam surface, a spring arranged on the pintle, one end of said spring being locked to the box lug, a cap for locking the other end of the spring to the lid, said cap beingv constructed to hold-the end-of the spring, and means for non-rotatably locking the cap to the lid.
