Application filed January 3, 1912. Serial No. 669,189.

T 0 all whom it may con-cam:

Be it known that I, HENRY F. Porn, of Cleveland, Cuyahoga county, Ohio, have in and useful Improvement in J ournal-Box-Securing Mechanism, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is aside elevation showing a portion of a side frame with a journal box having my improved retainer; and Figs. 2 and 3 are respectively side and end elevations of the lower portion of the box showing the hook shape of the movable retainer.

My invention relates to securing devices for journal boxes on car trucks, such as shown in the patent of J. J. Byers, No. 996,000, dated June th, 1911. In the structure shown in that patent, the bolt or similar securing device 13 threaded through an eye retainer at the bottomof the journal With such holders it will be neces the ledge of As of said patent is somewhat objectionable, and my invention'is desi ned to overcome this difficulty and reduce the requisite amount of jacking up in order to remove the jourinsert a new one. To that end, my invention consists in providing a movable retainer, which has means for, normally holding it in retaining position, but may be moved out of the way when desired. In the preferred form, the retainer is in the form of a swinging hook having a counterweight which normally holds it under the securing bolt 'or strap and in position to engage and retain this strap in operative position if the nut should work loose or be lost.

' In the drawings, 2 designates a side frame of the car trtick having at its end an overhung. extension 3 with depending rib or lip 4, to receive the journal box 5. The box fits against the horizontal bearing face 6, and a vertical bearing face 7, substantially at right angles thereto, and is held by a strap bolt 8. This strap bolt fits Within a suitable grooved recess 9 in the box, its lower end having a head 10 which may be slid up through a slot in the side the securing frame, the head engaging the rib at the side of the'slot. The upper end of threaded at 11 to receive a nut 12.

As the nut might through carelessness in assembling, become loose or work oil, it is desirable to provide a retainer; and to avoid the disadvantage of the retainer shown in the Byers patent above referred to, I pro vide a movable retainer, which is normally held in position to support the securing bolt in case the latter becomes loose throu h reakage or loss of the nut, but may e moved out of position. In the form shown, this takes the form of a hook 13, pivoted between depending lugs 14 on the ournal box and havinga counterweight 15, which normally holds the hook opening under neath the securing bolt. In case the nut becomes loose, or works off, the bolt would drop into the-hook retainer and remain in operative position and be held against dropping on the track. In case it is de sired to remove the box, the nut is un screwed, the retainer swung to one side, and

the securing bolt dropped straight down and out of its bearings.

The advantages of" my invention result from the use of the movable retainer, which is normally held in retaining position, but

may be moved out of position temporarily in case the securing bolt is to be removed.

Many changes may be made in the form and arrangement of the box, the securing device, the retainer, &c., without departing from my invention. I claim 1. A removable journal box for car axles, a securing device therefor, and a movable retainer attached to the ournal box and arranged to normally rest below but in position to support the retaining device in case of its becoming loosened; substantially as described.

2. A journal'box for car axles arranged to be held in place by a'securing device extending beneath the box, and a removable. retainer attached to the box and having means for normally holding it below the securing device and in position to support device in case it becomes loosened, substantially as described.

3. A journal, box for car axles arranged to be held in place by a securing device and a retainer pivoted to the bottom of the box and having means for normally holding it the bolt is in position below the securing device and in position to hold the securing device in case of its loosening; substantially as described.

l. A journal box having a hook-retainer pivoted to its lower portion and provided with a counterweight arranged to normally hold the retainer in operative position; su b stantially as described.

5. In a car truck, a side frame having a seat for a journal box open at one side and the bottom, and a strap or bolt securing the box to the side frame, said box having a movable retainer in its lower portion which is normally held in operative position underneath the strap or bolt; substantially as described.

6. In a car truck, a side frame having a journal box seat and a retaining strap or bolt securing'the journal box in place, said box having a pivoted hook-retainer underneath the securing bolt, with means for normally holding the hook in operative position; substantially as described.

7. A journal box for car axles having a removable retainer attached to its lower portionin position to extendbeneath and support a securing device if the same becomes loosened; substantiallv as described.

In testimony whereof, I have hereunto set my hand.
