RAIL-FASTENING CONSTRUCTION.

Application filed August 29, 1927. Serial No. 216,266.

My invention relates toa rail fastening construction.

One of the objects of my invention isl to provide a rail fastener whichy will have great strength and durability to enable it to withstand the rough usageto which such fasteners are subjected.

A further Object is to provide a rail fas tener which willy contribute to safety of travel by preventing rail spreading.

A further object is to provide ay rail .fastener which will be cheap to manufacture v and install.

A further object. is to provide a construction which will not require the use of skilled labor in installation. y

A further object is to provide a construction which will facilitate the repairA or replacement of the rails, plates, shims, or cushions resting on thebase member Without disturbing the base member.

A further object of my invention is to provide a rail fastener which will lengthen the life of the rail and prevent rail creeping by holding the rail absolutely tight to the base member.

A further object of my invention is to provide a fastener which will permit the use of cushions, plates or shims under the rails forgiving resiliency to the track.

A further object is to provide a fastener which can be used with any size or weight of rail.

A further object of my invention is to provide a simple, strong, and economical rail guide or guides to be'used in any base or foundation for railroad rails.

Further objects will appear from the description and claims.

In the drawings, in which several embodiments of my invention are shown, e

Figure 1 is a vertical transversel section showing a pair of fasteners holding the rail in place on the base member such as a tie or slab;

Fig. 2 Fig. l;

Fig. 3 is a section showing a slightly different form of fastening member.

Fig. 4 is a vertical section showing still another form of fastening construction.

Fig. 5 is a vertical section showing a different form of recess or opening in the lhase member, and

is a section on the line 2-2 of Fig. Y

-Referring to the drawings in detalfand first to Figs. l and 2, the construction shown therein comprises va foundation or -basev member l (which in the form shown may be a concretel tie, but. which might be ay concrete slab,y or 'a wooden tie,- or any other.spit-able` form of foundation or. base member),vf\airail 2 secured to this base or foundationmember, and a pair of fastening members 3 which extend into recesses kor openings L infthe foundation member `and which are secured in these openings hypouring molten metal 5 into the recesses aroundfthe. fastenlg members which solidies and securely holds the fastening members in the holesfor recesses with-the heads 6 of the fastening members. snugly engaging the lower flanges 7 of the rail, thus absolutely preventing. any spreading or creeping of therails. Before pouring the molten metalinto theholes around the openings, the'holes maybe partially filled withv dirt, sand, or any other convenient material Sto prevent the molten metal. from running through and to avoid using more molten metal than is necessary. This molten metal may be lead or any other suitable material which can be readily handled and which will have the desired quality of securely holding' the anchor members in place. concrete baseor foundation member should taper upwardly so that when the molten metal solidifies `it will be in effect a sort of wedge. the smaller end being uppermost so that it is absolutely prevented frombeing pulled upwardly or pulled out ofthe opening in the base, or pushed sidewise, this construction thus absolutely preventing endwise movement of the rail (creeping) and also absolutely preventing sidewise movement of the rail (spreading).

A shim or plate 9 of any suitable nonmetallic material such as wood, fiber, or other rubber-likeor cushioning material, is provided between the lower flange of the rail andthe foundation member if the base member is of concrete or metal. If a wood tie is used a metal plate might be used.

The constructionshown in Figl is substantially the same as that shown in Fig. 1 except that here the upper end of the fastening member is threaded for a clamping nut It is desirable that the holes in the pered, is enlarged atthe bottoni so that the if molten metal when solidified forms a sort of collar 13 around `the enlarged -`head` lll' ofk the fastening membemthus forming firm,v strong anchorage. Y l The construction shown in F1013.- 5 .and 6 1s 'substantially the same as that.' slioivn" Figs.V

- It will be seen that this constructionp'rovides a rail fastener 'which has'greatfstrength and durability and oneivli/.ichjwvill*effectue ally hold the rail toprevent'it fromspread ing( or creeping. It` ,will furthermore .be noted that the construction vvissuchthat it fc'anbe readily installed .ivithout the-"use'of skilled labor, as it involves positions ing the parts andV pouring in ,themolten metal- A A It Will furthermore bejseen Vthatthe con;

Vstruction facilitatesv repair'o'r replacementof l the rails since if it is desir'edto .remove Iembodied in lother forms covered and fined bythe appended claims.
