,DUST-GUARD.
srnorrron'rron forming part of Letters Patent no. 678, dated y 9 Applioationfiled December 29,1990. Serial Zita 1,630. (No model.)
Toall whom, it may concern.-
Beit known that I, JAMES TIMMs, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Dust-Guards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in dust-guards for car-axle journal-boxes, the object of the invention being to provide a guard which will effectually hug the axle and prevent the passage of dust or grit and which will entirely close the opening in the box for the admission of the guard.
With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a sectional View on the line we; of Fig. 2, illustrating the guard in position in a journalbox. Fig. 2 is a sectional View on the line y y of Fig. 1. Fig. 3 is a view of the guard removed, and Fig. at is a view of a modified form of my invention.
1* represents an ordinary journal-box, and 2 an axle projecting thereinto, the box being provided in its inner end withthe usual pocket 3 for the reception of the dust-guard.
My improved dust-guard comprises a lower member 1, grooved in its lower end to receive a strengthening-web 4 and provided with vertical parallel arms 5, having tongues 6 on their inner opposite faces, which are disposed in grooves in the opposite sides of the upper member 7, so that the two members may slide freely on each. other, but always maintain the same relation to the axle. The arms 5 are provided in their outer faces with grooves 8, in which coiled springs 9 are located, and said'springs are secured at one end to the arms 5 and at their upper ends to a bar 10, which latter is of greater length than the width of the lower member 1 and grooved or recessed to form atongue 11, which fits snugly into the upper end of the pocket 3 and entirely closes the same, thus preventing any possibility of the entrance of dust or grit therein. A bow-spring 12 is secured to the under face of the, bar 10, or rather to the tongue 11, and bears at its free ends against the top of the upper member 7 to press the same downward onto the axle, while the springs 9 pull the lower member 1 up against the axle. It will thus be seen that the members 1 and 7 fit snugly all around the axle and prevent any dust or grit passing them and entering the box, and as the bar 10 and tongue 11 thereon completely close the entrance to the pocket 3 there is no possibility of the dust finding its way into the box.
The springs 9 are of greater strength and power than spring 12, so as to hold the bar 10 down snugly on the box and resist the tension of the spring 12, which would otherwise have a tendency to raise the bar from the box and permit dust and grit to enter the pocket between the wall thereof and the guard.
When the guard is in position in the pocket, the upper ends of the arms 5 are disposed practically parallel with the bar 10 and are located some distance from the bar 10, so as to allow for the wear of the lower member 1 equal to the space between the upper ends of the arms and the bar.
Instead of providing a-bow-sprin g for pressing the upper member 7 downward I might employ a coiled spring for this purpose, as shown in Fig. 4:.
Various other slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.
Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is--- l. A dust-guard comprising a bar, a tongue thereon to enter and entirely close the dustguard pocket in a journal-box, a lower member, springs connected to the inner face of said bar and to the lower member for drawing the latter upward, an upper member and a spring between the under face of the bar and upper member for pressing the latter downward.
2. A dust-guard comprising a bar, a tongue thereon to enter and entirely close the dustguard pocket in a journal-box, a lower member having upright parallel arms, an upper member mounted between the arms and having sliding connection therewith, springs connected to the arms of the lower member and to the under face of the bar and a spring disposed between the upper member and the under face of the bar.
3. The combination with an axle, and a journal-box having a pocket therein, ot' a dust-guard adapted to be inserted into said pocket,said dust-guard comprising a bar to enter and close the open upper end of the pocket, at lower member, springs within the pocket connected to said lower member and to the bar, an upper member and a spring located within the pocket and disposed between said upper member and the bar.
4. In a dust-guard, the combination with a journal-box and an axle, of a lower member adapted to be disposed against the lower face of the axle, upright parallel arms on said lower member, an upper member mounted between said arms and having sliding connection therewith, a horizontal bar spaced from the upper ends of the arms and adapted to close the dust-guard opening in the box, springs connected to the arms and to the under face of the bar and holding the latter down on the box, and a spring in the pocket between the bar and upper member for pressing the latter down onto the axle.
5. The combination in a dust-guard, of two members, the upper member mounted to slide in the lower member, a bar spaced from the upper ends of the two members, the lower member having vertical grooves in its outer edges, springs disposed in said grooves and secured to the walls thereof, the upper ends of said springs connected with said bar, and a spring disposed between the upper member and said bar.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
JAMES TIMMS.
