JOURNAL-BOX--ALIGlNIAIiTGrl DEVICE. j

Application filed May' 21,

This invention relates to journal box aligne ing devices. i

In railway practice it has been found that the journal boxes in trucks of thepedestal type have a decided tendencyV to rotate about,

the axes of the journals, thereby gouging out the guide faces of the pedestal jaws,

eventually causing thefboxes to assume a permanently tilted condition which intere 1o fcres with the proper movement thereof.

This condition is much aggravated in trucks l provided with equalizer bars which bear upon the journal boxes, for under service conditions longitudinal movement of the equalizer bars exerts a marked tilting action upon the journal boxes, dition mentioned. j

An object of this invention is to provide a simple Vand efficient means for maintaining the journal boxes in vertical alignment in the ljaws of the pedestals against the tendency of vthe' same to be displaced, while permitting the required movement of the journal boxes, said means including elements connected to each journal box which extend to pointsgremote from the journal box and pedestal jaws Where they `are engaged by guide means which co-o erate therewith to permit movement ofV the journal boxes in a vertical direction only and to prevent tilting of the boxes about the axes of the journal or the box under service conditions.

Other and further objects of theinvention will more fully and clearly appear fromV the descri tion and claims hereinafter following. In t ie drawings forming part of this speciicatiomFigure 1 is a fragmentary side elevational View of a truck of the pedestal type, showing the invention in connection therewith. igure 2 is a Vhorizontal sectional view of the invention corresponding substantially to the line 2-2 of Figure 1. Figure 3 is a vertical sectional view ofthe invention corresponding substantially to the line 3-3 of Figure 2. And Figure 4 is a perspective detailed Vview of one of the guide elements used in connection with `the invention.

As shown in the drawings, a portion of the frame proper of a pedestal truck is indicated at 10, said frame being provided with a plurality of pedestal members, only one of which is shown, each pedestal member comprising a body portion 11 and spaced jaws 12-12 providing guide faces 13-13 for the journal box 14 which is slidably mounted between the aggravating the conf yoke 21.

jawslQ-lQ andvmaintained in position' by the bar 15. The jaws 12m-12 of each pedestal are transversely slotted as e indicated at 16l for thev reception of one end 17 of an equalizer bar 18 which bears on 'top of the journal box 2 in the usual manner, a spring 19 being interposed between the equalizer' bar 18 and the truck frame l0. 'g f The construction thus far described, is of a type in common use, and no. claim. is made Y thereto except in combination with the invention hereinafter described. In the con! struction Vjust described, the journal box 14 moves vertically in the pedestal jaws 12-12, certain necessary clearance being provided between the side walls "of the journal box and the guide faces of the pedestal jaws. Under actual conditions in starting up, or stopping, the journal boxes are tilted about the axes of the journals because of the relative movement between the` truck frame proper and the wheels and the equalizer bars, and when ruiming, the movement of each journal tends to tilt the box in `the direction of movement thereof. The'tilting movement of the journal boxeshowever caused, gouges out the guide faces ofl thepedestals andthe journal boxes eventually assume permanently tilted positions, interfering with the proper operation of the boxes ,and necessitating early renewal of the pedestal members.

The present invention contemplates means for confining each journal box Vto vertical movement within the jaws of the pedestal to overcome the conditions above noted, and'said means co-operate Vwith each journal box and the truck frame proper to hold. the box against this tiltingmovement. In carrying out the invention, the side walls of each journal box, at their outer ends, are provided with apertures adapted for the reception of trunnions 20-20, formed upon a 'detachable The yoke includes two separate parts 22-22, each of which includes a portion fitting along the side wall `of the box, 100 upon each of which one of the trunnions is mounted, Each yoke member alsoincludes an angular portion indicated at 23, and the inner ends of the portions 23 are provided with vertically projecting extensions 24e-24e. 105 The members 22-22, are oppositely disposed, and are 'detachably secured together by bolts 25, which in position maintain the trunnions 20-20 in the recesses in the walls of the journal box. i

Secured in spaced relation with reference to thejournal box and the jaws of the pedestal, is a guide member in the form of a bracket 26 secured to the body portion ll ofthe pedestal by means of rivets. The outer surface of the bracket is provided with an extension providing an eye 27, rectangular in cross section, in which are mounted the extensions Qe-Qfl on the yoke, said extensions being slidably disposed between the walls forming the eye, and operatinef to prevent lateral movement ofthe extensions but permitting free vertical movement thereof, thereby preventing tilting movement of the journal box.

n In this construction it should be noted that the guide member 26 is located as 'lar from the center of thejournal box and journal,

j as practicable, and securely anrhored, thereby providing the necessary clearance for movement of the extensions in the vguide means, while ,permitting relatively small movement of the oui-nal boi; in a tilting di rection and hence successfully overcoming the possibility of the box tilting in the pedestal jaws.Y i

While I have herein shown and described what I consider the preferred manner ot carrying out the invention, the same is merely illustrative, and I contemplate allchanges and modifications which come within the scope of the claims appended hereto.

I claim:

l. In a device of the character described, the combination with a truck having pedestal jaws, and a journal box mounted in said jaws for sliding movements; an equalizer bar hearing upon said "journal box; elements rigidly connecting with said journal box and extending to a point spaced from said pedestal jaws and said boxgand means izo-operating with the end portions of said elements to confine the same to vertical movcn'lent.

2. In a device of the character described, the combination with a truck frame and a pedestal member comprising a body portion and jaws, said body portion being secured to said truck frame; a substantially rectangular journal box mounted in the jaws ofsaid pedestal member for vertical movcmentf yoke means closely embracing oppositeyside edges oi said journal box and rigidly secured thereto, said yoke means havin g' an elongated guide stem; and an elongated guidemember lined to said truck frame accommodating said stem, for verticalsliding movement only.,

3. In a device of the character described, the con'ibination with a pedestal member and a journal box slidably mounted between the jaws of said pedestal member; a two-part yoke having trunnious engageablc in recesses in the walls of the journal bon, said yoke being;- provided with extensions; means for detachaliily securing the parts of thev yoke to- `gether; and means co-operating with the extensions on said yokefor confining: said extensions to movement in a. vertical direction. n j y l j Y In witness that I claim the foregoingl have hereunto subscribed my name this `17th day of May, 1927. y
