William H. Sale, Sandston, Va. Application May 5, 1941, Serial No. 391,903
4 Claims.
The invention relates to dust-guardcaps for journal-boxes.
One object of the invention is to provide animproved dust-guard cap for journal-boxes, which is readily removable from the journal-box and which, when placed thereon, will be effectively secured, so that the cap will not be loosened by vibration to which the boxes are subjected.
Other objects of the invention will appear from the detailed description.
The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof.
.In the drawing: Fig. 1 is a side elevation, partly in section, of a railway journal-box to which a dust-guard cap embodying the 'invention is applied. Fig. 2 is a transverse section taken on line 2-2 of Fig. 1. Fig. 3 is a perspective of the cap. Fig. 4 is a transverse section of the journal-box with a modified form of the invention. Fig. 5 is a perspective of the spring-pressed gripping member shown in Fig. 4.
The invention is exemplified as applied to a railway journal-box Iii for an axle II. The axle is journaled `in the box I0, as well understood in the art. A lid I 2 is pivoted to the box for access to the interior of the box so that lubricant can be supplied thereto. The box is also provided adjacent its inner end with a transverse chamber I3 in which is fitted the usual guard I5 around the axle for excluding dust and preventing the escape of lubricant through the inner end of the box. The sides of the box at the ends of chamber I3 are provided with integral ribs I5 with inclined shoulders I6 at their lower ends.
The improved dust-guard cap is preferably formed of sheet metal and comprises a top-wall I1 which overlies the open upper end of chamber I3 through which the dust-guard is insertable in the chamber I3; depending side-hanges I8, which are adapted to lap the outer faces of the walls around the upper end of chamber I3 and confine the cap on the box against movement longitudinally of the axle. At one of its ends the cap is provided with a downwardly and inwardly in clined fia-nge 25, which is adapted to engage and hook under the shoulder I6 on the rib I5 at one side of the box. At its other end the cap is provided with a depending integral wall 2I which is spaced laterally from the adjacent side of the box and is provided with a socket 22. The flanges I8 are extended downwardly to the lower end of wall 2I to reinforce said wall and to form a housing. A stem 23 is slidable axially in the outer end of the socket 22 and is provided at its inner end with a convex head 24.. i The convex face` of head 24 is adapted te engage the inclined shoulder I6 at one side of the box. A coil-spring 25 sur` rounds stem 23, fits in socket 2-2, isadaptedto engage head 24, and is loadedk to press the head 24 and stem against the box. A grip or handle 26 is fixedly secured to the outer endot stem- 23. The inward spring-pressure on the head 24 forces its inner convex face against the adjacent contiguous inclined shoulder I6 and draws hook ange 2lin against the shoulder I5 so that a downward Wedging pressure bythe liar-ige 20 and head 24 will keep the `top-wall Il tightly pressed against the top of' the journal-box'.
The cap can be removed'by pulling grip 26 outwardly a ,suiiicient distance to permit the head 2=i-to clear the adjacent shoulder I6 and'rib I5 so the cap can pivot at hook 20 on the'adjacen-t shoulder I6 until the head 24 clears the upper top of the bex. When the cap is removed from the journal-box the grip 26 serves as a st ep to limit the 4 inv/jard movement of the lieacillil by the spring 2 5.
A characteristic of this construction is that when the cap is applied to the journal-box, the spring 25 Will cause the cap to be secured on the box b-y the wedgi-ng action of iange 20 at one end of the cap and the spring-pressed convex head 24 at the other end of the cap. This results in eiectivel-y securing the cap to the journal-box against displacement by vibration while .the journal-box is in use.
In the modication illustrated in Figs. 4 and 5, the cap comprises a top-Wall I'I, a hook ange 20 and flanges I8 similar to those shown in Figs. 1 to 3. A member for gripping the shoulder I6 and rib I5 at one side of the box is formed of a strip of metal bent to form a hook 3i] which extends through a slot 3I in the top-wall Il, a curved abutment 32 adapted to engage the adjacent inclined shoulder I6, a member 33 which extends through the depending wall 2 Ia of the cap, and a grip 35 outside of the cap. A coil-spring 35 is seated in a socket 3%, engages the gripping member, is loaded to force said gripping member inwardly, and extends around a tongue 3l outstruck from said member. When this modified form of cap is applied to lthe journal-box, the abutment 32 is forced inwardly by the spring 35 and causes the box to be wedged between the hook 2t and the gripping member so that the cap will be securely held on the box. When the cap is to be removed the grip 34 can be pulled or pried outward a sufficient distance to permit the abutment 32 to clear the adjacent shoulder I6 and rib I5 so` that the cap can pivot on hook 20 and be swung upwardly away from the journal-box.
The invention exempliiies a dust-guard cap for a journal-box, which is simple in construction, can be readily applied to, and removed from the journal-box and which, when placed thereon, will be securely held by spring-pressure and wedging action, so that it will be held thereon against likelihood of becoming loose or removed in operation. The cap also effectively excludes water, sand and other foreign matter from the journal-box.
The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
Having thus described the invention, what IV claim as new and desire to secure by Letters Patent 1. A dust guard cap formed of sheet metal comprising a top-wall adapted to extend over the dust guard chamber of a journal Ibox, integral parallel side flanges depending from the top-wall, a depending integral hook at one end of the top wall shaped for wedging engagement with an external shoulder onone side of the box, an integral flange depending from the other end of the top-wall spaced from the side of the box and provided with an integral outwardly projecting cylindrical socket, a gripping element provided with a memb er disposed inwardlyvof the depending iiange and having an inner end shaped for wedging engagement with an external shoulder on the other side of the box and a handle disposed at the outer side of the flange for retracting the engaging member, a coil-spring held in said socket and engaging the gripping element for forcing it into wedging engagement with the shoulder on the adjacent side of the box.
