JOURNAL HOUSING FOR AXLEb OF LOGOMOTIVES AND RAILWAY CARS Filed July 11, 1930- FIGLI.

Patented May 23, 1933 UNrrEn STATES PATENT ortica CHARLES W. TODD, F SGHENEOTADY, NEW YORK Application filed July 11, 1930. Serial No. 467,225.

The present invention relates to appliances known as journal boxes or housings used in connection with axle journals for locomotives and railway cars.

55 The object of this invention is to provide a structure whereby the journal housing will be adaptable for easy removal from and replacement upon the journal and supporting frame, and to permit inspection and change ilo of parts when found necessary, and means for securing the housing when in use, against relative movement transversely of the vehicle and accidental disengagement of the housingfrom the frame. The invention is 1.5 particularly designed for such housings as 265,386, now Patent No. 1,797,361, granted Mar. 211, 1981. However in no sense 1s the invention limited to any particular type of anti-friction means and in the embodiment described in the present case, a type gener- 325 ally known in the art is employed.

Other objects and advantages of this invention, relating to the particular arrangement and construction of the several parts,

p will become apparent as the following dei tailed description proceeds. i

In referring to the drawing illustrating the invention, the scope whereof is defined by the appended claims:

Figure l is a vertical side elevation of the journal housing disposed within the frame pedestal; Fig. 2 is an end view of Fig. 1 partly in section; Fig. 3 is a fragmental plan view of Fig. l; Fig. 4 is a partial vertical lo side elevation ofthe housing and frame, em-

bodying a modification of the appliance shown in Figs. l, 2 and 3; Fig. 5 is an end view of Fig. 4l partly in section on the line V-V of Fig. il; and, Fig.y 6 is an isometric view of the combined shoe and locking device of the modification.

In the practice of the invention, referring descriptively to an approved embodiment thereof, which is herein exemplified, like 5' parts being designated by like characters,

it is understood that the axle 1, is provided with a journal la, at each of its ends.

While the invention is designed for use in connection with axles having eollarless ournals, it is to be noted, at the outset, that there 55, may be modifications of other details in va rious instances, as for example, various designs of the frame pedestals with appropriate differences, will be employed, depending upon whether the invention is to be employed in connection with a locomotive, a passenger or a freight car, or other vehicle. Furthermore, where the invention is employed either on standard equipment or old equipment for replacement, not only will the frame pedestal be suitably designed, but the journal housing'will likewise be suitably designed to accommodate it for use in such equipment. While in the embodiment illustrated in the drawing the pedestals are formed integrally with the frame, it is also contemplated to employ the invention in connection with frame pedestals of the detachable type. Such further modifications of minor details as may be necessary, will be well within the province of the mechanical skill of those versed in the art.

In the present case, two embodiments of the invention are illustrated in the accompanying drawing. In Figs. 1, 2 and 3, 80 the pedestal 3a for the journal housing 2, made integral with the frame 3, is a load supporting member, and is designed to bear on the housing 2. In Figs. 4 and 5 (illustrating the modification) the pedestal 3a is designed to bear on a shoe 9 (Fig. 6), which is disposed beneath the frame and which in turn vbears on the housing. In these embodiments of the invention as aforesaid, the vaxle 1, is provided with collarless journals 1a, which co offer no obstruction to the movement of the journal bearings and housings longitudinally over the axles. The frame pedestal 3a is provided with an extended lower portion 3b which allows a clearance space 6 between 95 its inner sides and the housing, permitting a relative vertical movement, whereby the pedestal may be jacked up away from the axle ournal in order to remove the housing or replace it upon the journal. The positive locking bolt 10, shown in Figs. 1, 2 and 3, is also vlitted with a clearance space, and the shoe 9 is allowed a revolving or vertical movement with the housing 2 when the frame separates from the housing. rlhe horizontal movement of the housing` 2 upon raising the trame pedestal for the purpose of removal or replacement of said housing, is dependent upon removal of the locking bolt 10, and in the modification, the supporting of the shoe vertically sufficiently to disengage the tongue on the housing (Figs. l and The collarless jo-urnal 1ct, is .reduced in diameter relative to the body of the axle 1. rlhe ournal housing 2, contains anv anti-friotion bearing mechanism, not shown, but which may be similar to that shown in my hereinbeifore mentioned copending application and the exterior diameter of the housing is made of slightly less diameter than the inner sides of the frame pedestal 3e, thus permitting the housing 2 to move longitudinally on the axle journal 1a for insertion upon or removal from the same. The frame pedestal 3a surrounds the housing 2 on its top and sides and provides an opening 5 between its lower. portions 3?), which extend inwardly so that the opening 5 is of less width than the horizontal exterior dimension Aot the housing 2, but of greater width than the exterior dimension of the axle journal la. Between the housing 2 and the extended lower portion 3b, of the frame pedestal 3a is the said space 6 provided to permit the relative vertical movement, whereby the frame pedestal 3a may be jacked up for removal et the housing 2 horizontally from or for replace ment of the same upon the aille ournal 1a. Alifter the housing 2 is removed, the axle 1 f ma be removed from the trame 3 b assin' D the journal 1o vertically through the opening 5.

It is important that the housing be held against trans erse movement relatiif'e to the locomotive or car when in use, and in the present instance, this is accomplishedby cooperating tongue and groove members, tongue 7, (Figs. 143) being formed on top ot the housing 2, laterally thereof, and groove 8' being 'formed laterally in the interior of the top Wall of the trame pedestal 3o. Correspondingly,in the modification, 4;6) the tongue 141 is formed on the top oit the housing 2, laterally thereof, groove 15 is f' formed in the bottom ci' the'shoe 9, groove 22 is formed in the upper side ot the shoe, and tongue 21, formed on the interior of the top wall oit' the tramo pedestal. 3a, the tongues and grooves cooperating with each other to prevent transverse movement of the housing relative to the locomotive or car.

The lugs 18 (Figs. 1-3) cast integral with the housing 2, lug 12 cast integral with the 'frame pedestal 3a and the bolt 10 disposed through channels in said lugs and secured by an enlarged head 4, and the split key 11, form a positive lock, preventing accidental disengagement of the journal housing 2, from the frame pedestal 3a, Correspondingly, the shoe 9 is provided with a locking element 9a, (Figs. 4 6) cooperating with the lugs 18 on the frame and the pin 17, to secure the housing' against accidental disengagement when the modilied form of the invention is used. lt will be apparent that while the housing of the embodiment shown in Figs. 1 to 8 inclusive, is locked against vertical movement relative to the frame, so as to prevent accidental transverse movement and disengagement, the housingoi the modilied form of the device illustrated in Figs. 4l to 6 inclusive, is not so locked, and may upon passing over uneven or rough track have a limited vertical movement with relation to the frame and move out of engagement with the top of the pedestal. Under these conditions, however, the shoe 9, by reason of its locking element 9a, will follow the housing, swinging on the pin 17, and prevent transverse disengaging movement of the housing. rllhe pin with the locking element 9a Will serve as a guide tor the shoe in bringing the parts back together, and the shoe, asy aforesaid, will secure the housing against accidental disengagement.

The locking element 9a is formed with an open end 16, to allow free movement with respect to the pin 17, which is secured in or cast integral with the lugs 18 on the trame pedestal 3a.

The open end 16 of the locking element 9a permits the shoe 9 to be applied to the trame pedestal 3a, through the opening 19, and the locking element passed over the pin 17, prior to the insertion of the housing 2, upon the axle journal 1a. A lever armv20 is provided on the shoe 9 above the locking element 9a by which the shoe may be revolved about the pin 17, to vertically hold the groove 22 against the tongue 21 and provide clearance for the housing 2 for its insertion upon or removal from the axle journal 1a.
