PATENT OFFICE.
THOMAS H. SYMINGTON, OF BALTIMORE, MARYLAND, ASSIGNOR TO T. H. SYMINGTON COMPANY OF DELAWARE.
DUST-GUARD FOR RAILWAY JOURNAL-BOXES.
SPECIFICATION forming part of Letters Patent No. 794,260, dated July 11, 1905.
Application filed July 18, 1904. Serial No. 217,119-
To all 1071 0777, it 711151.7 concern.-
Be it known that I, THoMAs H. SYMINGTON, a citizen of the United States of America, and a resident of 706 St. Paul street, city of Baltimore, and State of Maryland, have invented certain new and useful Improvements in Dust- Guards for Railway Journal-Boxes, of which the following is a specification.
My invention relates to certain new and useful improvements in dust-guards for railway journal-boxes.
The object of my invention is to cheapen the cost of constructing both journal-boxes and dust-guards and make the guard more perfectly prevent the entrance of dust to the box than has heretofore been possible.
The subject-matter of this application is shown and claimed broadly in my companion application, Serial No. 227 ,17 6, filed October 3, 1904:.
My invention comprises certain combination of parts, the preferred form of which will be first specifically described and the invention then pointed out in the claims.
Referring to the drawings, wherein the same part is designated by the same referencenumeral wherever it occurs, Figure 1 is a longitudinal sectional view of the rear part of the journal-box provided with my improved guard. Fig. 2 is a sectional view similar to Fig. 1, taken at right angle to Fig. 1. Fig. 3 is a View of the back of a journal-box provided with my dust-guard.
1 designates a journal-box of any desired form. This box is provided at its rear with an opening 2, through which passes the axle of the car. Around opening 2 I form a raised surface 3, the face of which is preferably machined and forms the bearing-face against which the dust-guard is pressed. The opening 2 is larger than the axle, as is customary.
4 designates a ring, which has an opening 5 therein of practically the diameter of the axle, the opening 5 being slightly greater than the diameter of the axle in order that the axle may turn independently of the ring.
6 designates a pair of springs, each of which is preferably bent into a pair of coils 7, as is The openings 10 are located in such a position that the loops 8 of the springs when they are in position press against the rear face of the dust-guard ring, holding the ring against the surface 3 on the box. It will be seen that by this construction the necessity for a dust-guard well is entirely done away with, cheapening the cost of manufacturing a journal-box, and as the guard consists merely of a single metal ring and two springs the cost of constructing the guard is materially lessened.
While I have described what I believe to be the preferred form of my invention, I desire to have it understood that many changes may be made in the form, construction, and arrangement of parts without departing from the spirit of my invention.
Having thus described my invention, what I claim, and desire to be secured by Letters Patent, is-
1. A journal-box provided with an opening in its rear end through which the axle projects into the box, a dust-guard ring encircling the axle outside the box, and a spring bent into a pair of coils connected by a loop,
the spring being secured to the box by its by their own elasticity, the loopof the spring resting against the ring whereby the ring is held against the box.
3. A journal-box provided with an opening in its rear end through which the axle projects into the box, a dust-guard ring encircling the axle outside the b0x,a pair of springs, each spring being bent into a pair of coils connected bya loop, the springs being secured to the sides of the box by their ends engaging the box and the loops resting against the ring whereby the ring is held against the box.
4. A journal-box provided with an opening in its rear end through which the axle projects into the box, a dust-guard ring encircling the axle outside the box,a pair of springs,
