GEORGE WV. DENNIS, OF HARVEY, ILLINOIS.
DUST-GUARD FOR RAILWAY-JOURNALS.
SPECIFICATION forming part of Letters Patent No. 762,154, dated June *7, 1904.
Application filed November 10, 1902. Serial No. 130,657. (No model.)
1'0 (all whom it may concern:
Be it known that I, GEORGE W. DENNIS, a citizen of the United States, and a resident of the city of Harvey, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Dust-Guardsfor Railway-Journals; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in dust-guards for railway-journals of that class adapted to engage around the journal at the rear of the oil-well and to prevent the entrance of dust, dirt, or other foreign matter into the journal-box through the journal-aperture at the inner end of the box.
The object of the invention is to provide a cheap, strong, and durable construction capable of withstanding the hard usage and continuous wear to which a device of the kind is subjected and to be also capable of quick and cheap repairs when desired or necessary.
It is also an object of the invention to provide means for holding the guard not only in yielding engagement with the journal, but also in yielding engagement with the outer side of the dust-guard pocket, thereby more efl'ectually protecting the bearing and the oilwell.
The invention consists in the matters hereinafter described, and more fully pointed out and defined in the appended claim.
In the drawings, Figure 1 is a side elevation, partly broken, of a journal-box and journal end provided with a device embodying my invention. Fig. 2 is an enlarged perspective view of the dust-guard, showing the same removed from the journal and journal-box. Fig. 3 is a top plan view of the same. Fig. t is an enlarged detail illustrating one of the means for lessening the wear at the sides of the dust-guard.
As shown in said drawings, A indicates the journal-box of the usual Master Oar-Builders type or other preferred construction, having a dust-guard pocket a at the inner end of the same.
B indicates the journal, which extends through the inner end of the journal-box, as shown in Fig. 1, and on which the journal-box and superposed weight are supported by bearings or brasses, which are omitted from the drawings.
Seated in the dust-guard pocket or recess, as shown in Fig. 1, is the dust-guard, which, as shown, is constructed of wood or other suitable material and comprises an approximately rectangular piece of board, fiber, or other suitable material C, out to fit closely in the sides and bottom of the dust-guard pocket and having the center and top cut away to provide the central semicircular seat for the journal and the upwardly-extending inwardly-beveled sides or arms 0. Between the upwardly-extending arms 0 is fitted the board or plate C of material similar to the board C and having beveled edges complemental with the inwardly-beveled edges of the lateral arms 0. The lower margin of said board is cut away to provide a semicircular seat corresponding with that in the lower member C, providing when the parts are assembled a circular aperture through the dust-guard of asize slightly smaller than the diameter of the axle where the same passes through the dust-guard pocket or journal. A plate 0 is rigidly secured on the outer side of each of said arms, as shown in Figs. 2 and 3, and project beyond the inner edges thereof, forming, together with said beveled edges, a slideway for the complementally-bevelcd edgesof the part 0'. A longitudinal groove is provided in the top of the part 0, and a spring D, as shown, formed of a wire or rod, is secured at one end on one of the arms 0 and bent to form a coil close to the top of said arm and at the other end extending over the middle of the part or plate C and into a slot in the top of said part 0. Said spring is so disposed as to press the part 0 at all times against the bevel of the arms. Springs E, also constructed of wire, are secured at one end in the face of each of the arms 0, near the lower part thereof and on the side adjacent to the oil-box, and are bent upwardly and outwardly, forming pushingsprings, which when the dust-guard is engaged in the recess or dust-guard pocket held in such close contact under the action of the springs E as to prevent dust, dirt, or other refuse finding its way into the box. With the dust-guard inserted in position, as shown in Fig. l, the upper and lower parts or plates being mutually adjustable under the tension of the spring 1) serve to lit themselves closely to the journal through the wear of the inner surfaces thereof. At the sides of the journal, however, where the wear is nearly as rapid as at the top or bottom, there has usually been inadequate provision for resisting the wearing effect of the rotation of the journal. To obviate this and as a further improvement, I insert in each of the arms in position to bear against the journal on opposite sides thereof the wear-plates F, which, as shown, are triangular and which are driven or otherwise inserted into the arm 0 and afford a metallic contact for the sides of the journal, thereby resisting wear. Any desired metal may be employed. Preferably, however, a metal slightly softer than the metal of the journal is used. The use of said wearing-plates obviates to a great extent the wear on the sides of the dust-guard and permits the dust-guard to adjust itself closely around the entire periphery of the journal. Obviously any desired number of said wear-plates may be used, and they may also be disposed at other points around the journal-aperture, and many details of construction may be varied without departing from the principles of this invention.
1 claim as my invention Acar-journal-box dust-guard comprising in combination a lower member shaped to fit the bottom and sides of a dust-guard pocket, upwardly-extending arms thereon having guideways therein, an upper member having a slot in the top and adapted to engage in said guideways, a coiled spring carried on one of said arms and adapted to engage the slotted top of said upper member, a spring rigidly engaged at its lower end in the face of said guard adjacent to each edge thereof and the other end extending outwardly and upwardly therefrom and a plurality of triangular metallic points rigidly engaged in the lower member in position for the outer edge thereof to contact with the journal and cause the member to wear concentric therewith.
In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
GEORGE WV. DENNIS.
