JOHN PEARSON, OF CHICAGO, ILLINOIS` JOURNAL-BOX.

Specification of Letters Patent.

Aatented AprllBO, 1907.

Application filed May Z, 1906. Serial No. 314.751.

I To a/ZZ whom it may concern:

Be it known that I, JOHN PnARsoN, a citi- Zen 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, reference being had therein to the accompanying drawings.

This invention relates to improvements in car journal boxes, and it consists of the organizati'ons and` arrangements of parts hereina'fter described and then pointed out in the appended claims.

In the accompanying drawingsFigure l is a view in front elevation of a car journal box constructed in accordance with my invention and showing a portion of the lid broken out to disclose the lid-spring and cams cooperating therewith; Fig. 2 is a vertical sectional view of the device of Fig. l, showing in Vfull lines the lid in its closed position and in dotted lines in its partially open position; Fig. 3 is a similar View showing the lid entirely open; Fig. 4l is a detail fragmentary side view of the box, Fig. 5 is a view illustrating a modification, and Fig. 6 is a sectional view similar to Fig. 2 showing a 'further modification of the invention. Fig. 7 is a detail view showing the button and lug on the lid Vfor the spring, together with a modi- 'lied form of spring.

The journal box l() may be of the usual or any preferred construction, except in the particulars hereinaf ter specified, and is provided with the usual 'front opening which is closed by a lid 1l.

The present invention has particular reference to the hinge connection between the lid and journal box and also the spring for holding the lid in its opened and closed positions.

The ,top of the box l0 is provided at its front above the box opening witha hinge lug 12. As shown in Figs. and 5, the upper face of the hinge lug l2 is curved in trans verse vertical section. This lug 12, in the construction'illustrated in Figs. l to 4, inclusive, is provided with a vertically elongated opening 13 extending transversely of the box, which opening is substantially oval in shape except that it is provided at its bottom at the side toward the front of the box with an angular shoulder lil extending the length of the opening 13 and the purpose of Which will be hereinafter explained. As the lid in this construction is designed to be moved vertically during the initial opening movement, the height of the opening 13 is at least that of the movement of the lid during the vertical movement referred to.

The hinge lug l2 is provided on its curved face and at the Vfront with a pair of opposite shoulders l5. In the present instance such shoulders are about 90 degrees in length, extending upwardly 'from substantially the horizontal axis of the lug l2 and being curved to conform to the curvature of the lug l2 as clearly shown in Fig. The shoulders l5 at their adjacent sides are provided with opposing cani faces a converging upwardly, opposing cani faces b diverging up wardly from the upper ends of the cam faces a, and 'merging into parallel opposing end faces c. The meeting point or crown of the cam faces a and b at each side of the box is slightly rounded, as shown in Fig. l. l/Vith this arrangement the shoulders provide a groove the side walls of which first tend to converge, then diverge and finally terminate in an end portion with 'the side walls parallel.

largement or hood I6 at its upper part and the side walls of this hood are provided with hinge lugs 17 having alined apertures to receive the pintle or hinge pin 18, which pin also passes through the opening 13 as shown in Fig. 2. The rear end of the hood is bent inwardly, as at 19, so as to practically abut against the hinge lug and. prevent the ingress ell dust at this point when the lid is closed.

The hinge pin 1S is circular in cross section except for a longitudinal segmental recess 2() corresponding substantially to the shape of the shoulder 14 for which it provides a clearance, as shown in Fig. 9, and which when the lid is closed, straddles the shoulder but does not rest thereon. The openings in the hinge lugs 17 are of the same cross sectional shape as the pin 18, as shown in Fig. 4, so that the pin is compelled to turn with the lid when the latter is swung to open or close the box. 'lhe lid ll is provided near the lower end of the hood 1G with a transversely disposed button 2l, the shank of which is curved ciosssectionally on its lower face as shown in Fig. l, and the head of which extends laterally on both sides of the shank as shown in Fig. 7. A lug 23 projects from the lid under the button 2l, and its upper face is substan The lid ll is formed with a hollow en- IOO tially concentric with the curved face of the button shank. A U-shaped spring 24, which is shown as formed of a strip of metal rectangular in cross-section, is seated between the button shank and the lug 23 and held from displacement either laterally or rearwardly by the button 21. The lug 23 prevents the spring from dropping downwardly. The

linesin Fig. 1, then slipping the limbs overv the button, then rotating or turning the spring at a right angle to the head of the button, as shown in Fig. 1, there being sufficient clearance between the button and lug 23 for this purpose, and finally compressing the ends to enter the groove between the faces c of the shoulders 15. In the assembled position the ends of the head ofthe button overlap the opposite limbs of the spring which are under tension between the shoulders.

On the outer faces of the side walls of the box are lugs 25 which are beveled at their rear faces, as at 26, and are designed to be engaged by rearwardly extending hooks .27 on the lid to hold the lid in locked position.

l/Vhen the lid is in closed position the hooks 27 engage the lugs 25 as shown in Fig. 41, the converging ends e of the spring reacting against the cam faces a, and as the limbs of the spring are then under tension, they press the lid downwardly and hold the same firmly to its seat. To open the lid the latter is slid upwardly far enough to clear the hooks 27 of the lugs 25, and in this position the point of the shoulder 14 will be in the line of the circle of the pintle 18. The lid is now swung outwardly turning the pintle so that it rides on the shoulder 14, as shown in dotted lines in Fig. 2, the curvature of the hinge lug and also the cam shoulders 15 then being substantially concentric with the hinge pintle. During this initial movement the converging ends e of the spring are passing the cam faces d which due to the cooperation of the parts force the limbs of the spring toward each other and put them under greater tension. As soon as the junctures of the angular portions of the limbs of the spring ass the crowns of the cam faces a and tie limbs will react against the divergingly disposed cam faces b and cam the spring and consequently the lid into its open position, as shown in Fig. 3, in which position it is held by the cooperation of the cam faces b with the angular portions d of the spring. In closing the lid the latter is swung downwardly on its pivot until the hooks thereof rest on the lugs 25, as shown in dotted lines in Fig. 2, the lid is then pushed rearwardly, and as soon as the hooks pass beyond the upper faces of the lugs the inwardly converging ends e of the spring which have been drawn down over the crowns react against the cam faces a and will be cammed' downwardly sliding the lid into its closed position. With this arrangement it will be seen that while the initial opening movement of the lid is performed manually the final opening movement is performed automatically by the cooperation of the spring with the cam faces b. In closing the operation is manual until the hooks clear the lugs when the final closing movement is performed by the cam faces a and cooperating ends e of the spring.

The arrangement of the cams and spring may obviously be reversed, as shown in Fig. 5. In this figure the hinge lug 12 is provided with a central shoulder 28 having the cam faces a and b, corresponding to vthe cam facesc and b, respectively, of Fig. 1, located at the sides thereof. 1With this arrangement, the portions d of the spring are bent inwardly and the terminal portion c bent outwardly. The operation is the 'same as that heretofore described.

In Fig. 6 I have shown a modification in which the locking lugs and hooks are omitted. .ln this construction the hinge opening 29 is circular and the hinge pin is also circular in cross section. Except for these changes the construction may be the same as that heretofore described. Vith this arraiigement the movement of the lid is performed manually until the angles of the spring pass the crowns of the cams c and Z), when the lid is auto matically thrown to its full open position by the cooperation of the angular portions a, of the spring limbs with the cam faces b. In closing the lid, as soon as the angles of the spring pass the crowns of the cams, the'lugs 25 being omitted, the lid is closed automatically and does not have to be pushed inwardly as is necessary when such lugs are employed. It is obvious that the spring may consist of a single limb instead of a pair in which case only one pair of cam faces a and b need be employed.. Such single limb may be secured to the lid by bending its lower extremity around the button shank, as shown in Fig. 7. I prefer, however, to employ the two limbed spring, as .the limbs acting in opposition to each other serve to balance the lid and prevent tilting of the hinge pin.

By reason of the arrangement described, the spring may be readily replaced in the event that it becomes broken or unduly weakened, and in such case it is only necessary to remove the lid and turn the spring so that it will slip off the button.

Having described my invention what I claim, is

1. The combination with a journal box having a hinged lid, of cams fixed to the box,

IOO

and a U-shaped spring carried by the lid and cooperating with the cams to move the lid into and hold it in its closed position.
