JOURNAL-BOX.

Specification of Letters Patent.

Application filed July 21, 1908.

Patented Nov. 58, 1911.

Serial No. 4411,60?.

To all wiz/cm it may concern:

lle it known that l, @nantes lf. ltllnnunr, a citizen of the United States, and resident of Chicago, county of Cook, and State of lllinois, have invented certain new and useful linynoveinents in Journal lieues, of 'which the ffillowing` a specification.

lilly invention relates to journal boxes and has particular reference to means for opeiating,` the closure or lid therefor.

l@ne of the objects of my invention is to provide a closure for a journal box which shall be positive and effective in its action at all times. ln order to secure this, it is necessary to so place the spring operating; means that they can not be affected by heat, resulting from an overheated ournal, or from oxidation. To accomplish this end 1 conipletely inc-lose the springI within an aperture in the journal box lu g, closing the end thereof tightly by means of a spring follower.

rl. further object is to provide a journal box of this type which shall be of the lll/ll. C. B. standard and which shall permit of the interchange of lids if necessary. lt frequently happens that a lid is broken on the road and it is desirable that any lll/l. C. ll. lid can be applied thereto at once.

Further advantages will appear hereinafter.

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

Figure 1 is a front elevation partly in section showing` my invention; Fig. 2 is a side elevation also in section on the line 2-2 of Fig. 1; Fig. 3 is a horizontal section on the line 3 3 of Fig. 1; Fig'. 4l is a perspective of a cani nut; and 5 illustrates a modification of the invention shown in Fig. 1.

Referring1 more particularly to the drawings, la is the journal bon; l, is the journal box closure or lid. Upon the top of the journal box, A. l provide a boss or lug, i', havingan aperture therein, one portion, 7, of which is contracted to the size of the journal box bolt. The main portion, 8, is slightly enlarged and squared to accommodate a spiral spring', 8, while the outside portion, 9, is still further enlarpged to aceoinmodate a spring' follower, 10 and the squared portion of the bolt. rlhe bolt, l1, has a head, 11a, and a squared portion, 11b. At the opposite end l provide a squared portion, 11C, for the accommodation of the cani nut, l2, which has a squared aperture, 12u. .After the parts are assembled the bolt, 11, is headed over the cam nut as at 11d. The lid, l, is provided with the upstanding portions, 13%13, one edge, 13, of which is provided with a cam surface for cooperation with the cam nut, 12. Upon the interior of the lid, B, l provide flanges, 14, adapted to fit closely within the journal box opening` and flanges, 15, are provided for fitting; closely around the outer edge of the ournal box opening Upon the interior of the journal box, A, l provide a depending lip, 1G. which is adapted to prevent the escape of oil from around the box opening.

'lhe parts may be assembled as follows: 'lhe spring, 8, is placed within the opening, 8, a spring follower', 10, is placed in the opening, 9, and the lid is placed over the lug, 6. ylhe follower is then held tightly against the lid. rlhe bolt, 11, is then placed in position and the cam nut is secured thereon by heading the outer portion, 11d, of the colt, 11. Upon lifting` the lid it will be seen that the bolt will revolve the cam surfaces upon the nut and lid, pressing; the spring still farther. As the lid is lifted, the cani surfaces will cooperate against flat portions and the lid may be maintained in any desired elevated position.

Referring to the modification shown in Fig. 5. it will be seen that the bolt` 17, is of uniform diameter, except at itsI ei;- treme end where it is squared at 17L for the accommodation of the cam nut, 18. The lug upon the journal box has an opening similar to that shown in Fig. 1, its end portion, 19, being` squared for a short distance for the accommodation of a square spring; follower, 20. This follower, Q0, is adapted to be secured to the bolt, 17, by means of a pin, 21. Upon one end of the lid, B, l pro vide a counter sunk portion. 2Q, the inner face of which is provided with a eain surface, 23, adapted to coperate with the cani nut, 1S. yllhe other end of the lid may also be countersunk as shown at 2.41, if desired. ln the top of the lug, 6, of the journal box, l provide a slot, 25, through which the pin, 21, may be placed in or withdrawn frointhe follower, 20. This construction is assembled as follows: The springe; is placed within the aperture, 19, the follower is next located in the squared portion, the lid is forced over vthe lug, 6, thus compressing the spring to a certain eXtent, the bolt is next placed in position and the cam nut riveted over its squared portion. Upon the lifting of the lid it will be seen that the cam, 23, will reciprocate the bolt, 17, against the compression of the spring.

The forms above shown are both adapted to be interchanged by any M. C. B. lid by simply removing the spring, replacing the ring, l0, as shown in Fig. l, or the square follower, 20, shown in Fig. 5, thus leaving the bolt opening through the lug of standard size.

As varicus 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:

l. A journal box provided wit-h a lug having an aperture therethrough, a spring and a spring follower within said aperture, in

combination with a lid having a cam surface upon one portion thereof and a bolt adapted to be reciprocated against the compression of said spring by means of a cooperating cam upon one end thereof, substantially as described.

2. A journal box having a lug upon its upper surface, said lug being provided with an aperture therethrough of varying diameter, a spring and a spring follower held within said aperture, in combination with a lid, and a bolt passing through said spring, spring follower, lug and lid, said lid and bolt having cooperating cam surfaces adapted to reciprocate said bolt against the compression of said spring, substantially as described.

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