TRACK "LEVEL,

Application filed February My invention relates to track levels for use in railway construction and is adapted to show the level of the rails.

It is van object of my invention to provideV a track .level of Jmetallicv construction which is insulated so as notl to electrically connect the rails and wherein the spirit level is supported in such manner that it may not easily get out of adjustment.

It is also an object to provide a supporting staff for one end of the level to indicate the difference in level between the two rails. 1t is also desired that the means for noting` the space between the rails be placed in such position as to be readily readable by the user.

Further objects and advantages arising from the particular construction and arrangement of the parts will be brought out with` more particularity in the specification which fol-Y lows. Y

Referring to the drawing herewith7 Fig. 1V is a side elevat-ion of a level embodying my construction shown in position upon the rails. Fig. 2 is a top plan view thereof. Fig. 3 is central vertical section of the device. Fig. 4 is an end elevation thereof. Fig. 5 is an elevation of the end oppositerto that shown in Fig. 4. Fig. 6 is a vertical section taken on the plane 6-6 of Fig. 3, and Fig. 7 is a side elevation of the measuring stati' employed in connection with my invention. Like numerals of reference indica-te like parts in all the views.

In construct-ing the body of my invention, I contemplate using a tubular metallic body 1, which is preferably made rectangular in cross-section. The interior of the body is thus left unobstructed and an opening 2 is formed on the upper side adjacent one end thereof to provide a view of the spirit level which is mounted within the tubular body.

The two ends of the tubular body are closed by end plates 3 and 4. These plates are formed to tit about the ends of the tube, the plate 8 having an upper portion 9 riveted or screwed to the body of the device and a lower extension 5 lying along the lower side of the body 1 and connected thereto by screws or rivets 6. Secured on the lower port-ion 5 of the end plate is a strip 7 of insulating material, adapted to rest upon the rail and thus prevent the passage of an electric current from one rail to the other where the tracks have been wired for electric block signals.

iece rigid material 8,- shaped like an angle iron, is connected to the plate 5 and 16, 1925. Serial No. 88,509.

downwardly extending arm thereon adapted to rest against the inner side of the rail. This member is also made of some type of insulat-v ing material.

The plate l at the opposite end of the body has an upper member 9', similar to the opposite plate, resting upon the upper'face of the body member. The plate closes the end of the tube and extends along the lower side at 10 for connection therewith, and is attached to the body by means of screws 11. A plate ofinsulatin'g material 12'on the lower side of the member 10 is adapted to rest upon the'rail and thus insulate the connection.

The two end pla-tes vare Aformed with vertical` slots 13 therein at a point spaced somewhat above the middle thereof, and'transversely of these slots the plate is recessed at 14: to receive a pin 15. A wire or rod16 of resilient-material is extendedlongitudinally ofthe interior of the level, the ends of said wire or rod being bent to connect about the ypins 15. The `said wire y16 hason the end adjacent the plate 3 a tension springl', which is connected to the wire 16 through the means of a button 18 of insulating material, the end ofthe spring being wound about the button and the wire 16 beingconnected through a central opening in said button. vThis spring tends to hold t-he wire 16 in a taut position on a line directly connecting the pins 15 which are uniformly spaced from the lower side of the body.,

he spirit level 19 is secured to the wire 16 on the upper side .of said wire and is preferably soldered or welded rigidly upon the wire. The level is open on the upper side so as to be viewed through an opening 2 by the operator. l

In ascertaining the difference in level be@ tween the adjacent rails. an adjustable-stati2 2O is arranged at the end of the body opposite the stop member 8.l and .it is contemplated that the stop member 8 will be placed against.

Illu

the higher of the two rails and the. staff 2() will. be adjusted upon the lower rail untill the body of the level is in a true level position. The said staff 2O is formed of a strip or plate of metal. the lower end of which is bent at right angles thereto to form a foot 21. The staff is slotted centrally at 22 to receive a cross bolt 23 having a thumb nut 24 thereon. which may be tightened against the .stati foliold it in any vertically adjusted posit-i n' The 'the main tlrliition t is' lli) graduated'as shown at, 25 in Fig; 7, so that: the height`- offthe levelabove thecfoot llof the staff may be indicated. This scaleJviH. beso graduated that the differenceinfheiglit1A between the two rails may be read directly from the scale. lVhen in use, the stati willhe in a position indicated in Figs. 8 and 4t, but when the level is used fOr-ordinary purposes to level up the rails, the staff .will not be of usen-nd will bepi voted on-the/ adj listingy .bolt 23fsothatthe-foot 21; will lbie brought:around" againstthe end plate. 4 andthe stattfwill 'their vbe moved into close contact with the svi-de and' endyasfind-icated iii-Fig, l., whereitmvillbe outioffw-ayuntil `fits. use is fdesired-.-
