'R AlLWAY-TRACK STRUCTURE.
SPECIFICATION forming part of Letters Patent No. 729,057, dated May 26, 1903- Application filed November 13, 1902- Serial No. 131,093. (No model.) I
To aZZ whom it may concern:
Be it known that I, ARTHUR L. GEORGE, of
Johnstown, in the county of Oambria and State of Pennsylvania, have invented a new and useful Improvement in Railway-Track Structures, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification. to This invention has relation to fastenings for the renewable portions or plates of railway-track structures, and more particularly to fastenings formed by bodies of a relatively soft retaining material seated partly in the I5 body portion of the structure and partly in the renewable portion or plate, as described in the application of George H. Parmelee, of Johnstown, Pennsylvania, Serial No. 131,082, filed November 13, 1902.
The object of my invention is to provide simple means whereby fastenings of this character may be readily and quickly released from the surface of the structure without disturbing the structure as a whole and without removing any portion of the adjacent pavement.
To this end my invention consists in a track structure having a renewable portion or plate secured in the body of the structure by means 0 of laterally-extending bodies of retaining material seated in the body and in the plate and having integral connecting portions lying between the body and plate and a drill-passage leading from the surface of the structure to the said connecting portions, whereby said portions may be reached and severed by a drill or boring-tool.
My invention also consists in the novel construction and combination of parts, all substantially as hereinafter described, and pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure l is a plan view of a frog or curve cross embodying my invention; Fig. 2, a section on the line 2 2, Fig. 1; Fig. 3, a side view of the plate removed; Fig. 4, a section on the line 4 4 of Fig. 1 with the plate removed, and Fig. 5 a fragmentary detail View.
The letter A designates the body portion of the structure, formed with the pocket at for the track-surfaced wear-plate B.
O designates the diverging rail members of the structure. T'
d d designate laterally-extending pockets or cavities formed, respectively, in the side walls of the pocket a andin the sides of the plate B. Each pocket d is directly opposite one of the pockets d, as shown.
D designates retaining material which is poured around the plate in a liquid state and forms a bedding and leveler therefor. This retaining material also fills the pockets or cavities d d in the manner shown in Fig. 2, and thus forms a secure fastening for the plate. Adjacent to these pockets the sides of the plate and also the side walls of the pocket a are formed with semicylindric cores h, leading to the portions of the retaining material which connect the bodies thereof, which fill the pockets d d, and preferably extending slightly below the same, as shown. These cores form drill passages or guides, which fill up with the retaining material when the latter is poured, but which can be readily drilled or bored out when it is desired to remove the plate. At such time a suitable drill-bearing brace or knee may be attached to the structure by means of recesses, such as indicated at g, or in any other suitable 8o manner, and by the use of a hand or power driven drill or boring-tool the connecting portions of the retaining material can be cut in two, thereby releasing the plate. To save time in drilling, the cores it can be filled up with plugs of wood or other soft material, as shown at Fig. 5, the retaining material being poured in at the recesses g, or two or more of these cores may be plugged up and the retaining material be poured in at the remain- 9o ing cores. In either case the plugs employed should be provided with small vents. These plugs can be readily cut or dug out-and reduce considerably the time and work of drilling.
Any suitable retaining material maybe employed. Ordinary commercial spelter is a very satisfactory material, as its toughness and hardness enable it to stand satisfactorily the severe hammeringand pounding which the plates receive in service. It is of course harder to drill than other material which may be employed, such as alloys having lead for their base.
I have shown the pockets (1 d as being of dovetailed formin order to take up shrinkage which may occur. This feature, however, I do not claim as my invention, nor do I wish to be limited to pockets of this shape.
Although I have illustrated my invention in connection with a frog or curve cross, it is equally applicable to all forms of track structures in which a renewable portion or plate is seated in a pocket in the body portion of the structure.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A railway-track structure having a renewable portion or plate secured in the body of the structure by means of laterally-extending bodies of retaining material seated in the body portion and in the renewable portion or plate, with integral transversely-exten ding connecting portions lying between the body and plate, and drill-passages ieading from the surface of the structure to said connecting portions.
2. In a railway-track structure, the combi nation of the body portion, the plate seated therein, and the retaining material bedding the plate and filling oppositely-located laterally-extending pockets in the body portion and plate, the said body portion and plate being each recessed from the said pockets to the surface of the structures to form drill-passages, substantially as described.
3. In a railway-track structure, the combination of the body portion, having the laterally-extending pockets, and the plate having similar and oppositely-located pockets, and also lateral recesses for the application of a drill-bearing, said body portion and plate also having recesses leading from the surface thereof to the mouths of said pockets and forming drill-passages, and retaining material bedding the said plate and filling the said pockets.
In testimony whereof I have affixed my signature in presence of two witnesses.
ARTHUR L. GEORGE.
