JOURNAL-BOX.

- Application filed May 16, 1913.

T 0 all whom it may concern Be it known that I, DONALD G. DAVIS, a citizen of the United States, residing at Depew, in the county of Erie and State of New York,- have invented a new and useful Improvement in JournaLBoxes, of which the following is a specification.

This invention relates to car journal boxes and particularly to an improved construction of means for operating the lid of a. box and holding the same closed. In journal boxes for car axles it is necessary to provide lids to close the boxes so as to prevent the entry of cinders, dirt and water thereinto,

and in order to maintain the lids in close en-- gagement with the ends of the boxes so as to enable them to properly perform the desired function and also to prevent rattling,

- springs are commonly employed.

The "present invention provides an improved construction whereby a coiled or helical spring, possessing a greater degree of resilience than the flat springs usually applied to journal box lids, may be employed on the inside of the lid. The use of such coiled springs involves the provision of a forwardly projecting block or abutment attached to the top of the journal box and the present invention provides an improved construction for this abutment, whereby the same may be detached from the journal box so as to permit the application to the box of a standard M. G. B.v lid if desired.

The present invention also contemplates an improved bearing for the lower end of the helical spring and certain other features of improvement, the nature of which will appear from the following detailed description.

In the accompanying drawings: Figure 1 is a front elevation of a journal box and lid embodying one form of the invention, a portion of the lid being broken away. Fig. 2 is a vertical central section through the front part of the journal box and lid, the position of the lid when open being shown Fig. 3 is a fragmentary sectional view on line-3'-3, Fig. 2, on an enlarged scale. Fig. 4 is a fragmentary sectional view on line 4%, Fig.' 2, on an enlarged scale. F'g. 5 is a view similar to Fi g. 1, showing modified construction. Fig. 6 is a vertical central sectional view through the front end of the journal box and the lid shown in Fig. 5,. Fig. 7 isa detail sectional Specification of Letters Patent.

view on line 77, Fig. 6. Fig. 8 is a fragmentary vertical sectional View of another modified construction.

Referring particularly to Figs. 1 to l, 1 designates a journal box which may be of any usual or well known construction. This box has an open front which is adapted to be covered by a lid 2. At the top of the box are a pair of perforated lugs 3 connected by a web 4. The lid 2 is provided with pintle bearings 5 and with a hood or pocket 6 adapted to extend up over the lugs on the top of the journal box and also to receive the lid operating spring and its associated parts. The lid is pivoted to the ournal box by means of a pintle 7 extending through the bearings 5 and holes in the lugs 3. The web 4 preferably has a substantially vertical flat front face 8 and a flat top face 9 disposed at an angle to said front face, the formation. of these parts being such as to adapt them to cooperate with the Well known fiat spring of the ordinary M. C. B. lid so as to hold such a lid in open or closed position upon the box in a well understood manner. vention, however, instead of the lid '2 being provided with a fiat spring as in the M. C. B. lid. a coiled or helical spring 10 is used. This spring is mounted upon aguide rod 11 having a pivotal engagement at its upper end with a block 12 secured to the web 4. The pivotal connection between this rod and the block may, be of any suitable nature but preferably the-block is provided with two arms 13 connected by a transverse pivot pin 14, and the rod 11 is provided with a forked upper end or head 15 adapted to engage this pivot pin between the arms 13. The upper end of'the spring 10 engages the lower face of the head 15. The lower end of the spring 10 is caused to act upon the lid 2 in any suitable manner. In the preferred construction illustrated, the lid 2 is provided with a pair of inwardly projecting lugs 16 in which. are slots 17 An abutment or guide block 18 is supported by these lugs by means of trunnions 19 projecting intothe slots 17. The block 18 has an aperture 20 therein through which the lower end of the rod 11. passes and is guided. The lower end of the spring 10 rests upon the upper face of the block or abutment 18.

The block 12, which is separate from the journalbox, may be secured to the Web 4 In accordance with the present inand lugs 3 at the top of the journal box in any suitable manner.

In theconstruction shown in Figs. 1 to 4, the block 12 has a screwthreaded socket therein into which screws the threaded end of an eye-bolt 21. The head of this eye-bolt seats in a recess 22 formed in the rear face of the web 4, while the pintle 7 passes through the eye of the, bolt. The pintle is preferably provided with a portion 23 of reduced diameter adapted to be engaged by the wall of the eye in the bolt head when the bolt is tightened upon the eye-bolt, thus serving to hold the pintle against longitudinal displacement. 'With a pintle of this construction it is unnecessary tov use any other locking means, such as the customary cotter pin, nor need the pintle be provided with a head. The eye bolt is held against rotation by its engagement with the walls of.

the recess 22 and by the passage through its eye of the pintle while the block 12 is prevented from unscrewing from the bolt by the engagement with it of the head of the guide-rod 11. l i The apparatus above described is assembled by placing the lid in position and pass ing the pintle through the bearings 5, holes in the lugs 3, and the eye of the bolt .21 which is loosely placed in itssocket. The lid is then lifted to the position shown in dotted lines in F ig. 2, when the block 12 can be readily screwed upon the .threaded part of the eye-b olt. The block is screwed up until it engages firmly against the front face of the web 4 and draws the eye-bolt into its seat and into engagement with the portion of the pintle of reduced diameter.

This locks the pintle, eye-bolt and block firmly in position. The block or abutment 18 is then placed in position between the lugs 16, the trunnions 19 being readily engaged with the slots 17 by inclining the blocks to the plane of the lid. The spring 10 is then placed upon the rod 11 and the lower end of the latter is passed through theopening in the block 18. The rod- 11 is then forced in the direction of the block 18 and the spring 10 is compressed sufliciently to permit the forked head 15 of the rod-to be engaged with the pivot 14 carried by the block 12. The rod is then released and the spring 10 holds the forked head in firm engagement with'the pivot pin. The spring being still under some compression holds the lid in the open position shown in dotted lines in Fig. 2. As the lid is forced down, the line or reaction of the spring passes from one side of the pivotal axis of the lid to the other so that'when the lid is'closed the spring holds the same'firmly against the end of the journal box, thus securing the desired tight'joint and hold ing the lid firmly against rattling.

The parts may be disassembled as readily maybe attached thereto in the. usualmanner.

In the modification shown in Figs. 5, 6

and 7, the journal box 1, lugs 3 and lid 2 are of the same construction as that described. The lid 2 is pivoted to the lugs, however, by means of the ordinary pintle 80 providedwith a head 31 and held in position by a cotter pin 32. The block 33 to which the spring guide rod is pivoted is provided with a rearwardly projecting lug web 4 connecting the lugs 3 and is provided with an aperture or eye 36 through which the pintle 30 passes. The pintle in this way holds the block 33 in position. The block is provided with the forwardly projecting arms 37 between which is pivoted, by means of a pivot 38, the head 39- of the spring guide rod 40. The lower end of the latter slides in a sleeve 41, having laterally projecting trunnions 12 which are received in the slots 17 in the lugs 16 of the lid. The spring 10 fits over an enlarged portion of the guide rod, its upper end engaging moving thecotter pin 32 and the pintle 30 the lid and block may be removed anda standard M. C. B. lid attached to the boxby the pintle 30.

Fig. 8 shows a modified construction embodying some of the features of each of the two constructions above described. The box 1 and-lid 2 are of the form already described. The lid 2 is pivoted to the lugs on the box by a pintle 30 which also holds in position a block 33' as described in connection with Figs.- 5, 6 and 7. The block 33 has the forwardly projecting arms 37 connected by the pivot pin 38, which is engaged by a forked head 39 on the guide rod -10 similar to that on the guide shown in Figs 1 to 4. The guide rod, however, instead of engaging the sleeve ll is made long enough to pass through the central aper ture in a block 18, such as described in connection with Figs. 1 to =1. The spring 10 is mounted on this guide rod and abuts against the head 39 and the block 18 at its respective ends. Other modifications than those illustrated may obviously be made in the invention.

In each of the constructions described the block for the pivotal connection of the upper end of the spring guide rod consists of a separate piece secured to the upper por- 3 which .fpasses through a notch 35 in the tion of the journal box. A block of this sort can be readily forged or cast and if broken can be replaced at small expense, in addition to the fact that it can be detached to permit the use on the box of an' M. C. B. lid.

I claim as my invention:
