TRACK-SURFAGING LEVEL.

Specification of Letters Patent.

Application ined June 25, 190s.

Patented Aug. aa, ieee. Serial No. 440,346.-

To all whom it may concern:

is provided at its front and rear ends with Be it known that we, ORBEY H. TOLLEY approximately inverted U-shaped rail-engagand JOHN T. TAYLOR., citizens of the United States, residing at South Boston, in the county of Halifax and State of Virginia, have invented a new and useful Track-Surfacing Level, of which the following is a specification. l

The invention relates to a track surfacing level.

The object of the present invention is to provide a simple, inexpensive and efficient track surfacing level, adapted to take the dips out of a track without requiring a civil engineer to set stakes for such operation, and capable of accurately surfacing tracks both on a level and on a grade.

A further object of the invention is to provide an instrument of this character, adapted to be used on any per cent. grade and capable of enabling the proper elevation to be given to curves. j

Vvlith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.

In the drawing z-Figure 1 is a perspective view of a track surfacing level, constructed in accordance with this invention. Fig. 2 is a transverse sectional view, illustrating the construction of the track-engaging clips of the longitudinal level bar. Fig. 3 is a detail elevation, illustrating the means for securing the pivoted level 'bar in its adjustment. Fig. a is a vertical sectional view, taken substantially on the line 4--1 of Fig. 3. Fig. 5 is a detail sectional view of the front end of the longitudinal level bar, illustrating the front track-engaging clip and the adjustable end of the transverse level bar.

Like numerals of reference designate corre- -sponding parts in all the iigures of the draw- 1n gi designates a longitudinal level bar, designed in practice to be a rod, in length, and adapted to be arranged upon a rail lengthwise thereof, as clearly illustrated in Fig. 1 of the drawing. The longitudinal level bar 1 ing clips 2, consisting of a pair of depending spaced lugs or projections, anda horizontal connecting portion. The horizontal connecting portion is secured to the lower face of the longitudinal level b ar, and the depending lugs or projections are adapted to engage a rail 3 at opposite sides thereof, as clearly shown in Fig. 2 of the drawing. The railengaging clips enable the longitudinal level barto be quickly placed on a rail in proper position.

The longitudinal level bar is braced by oppositely inclined bars or braces 4 and 5, having their lower ends let into recesses 6 and 7 of the outer face of the l; ar 1. The inclined braces 4t and 5 stiften the bar 1 and prevent the same from breaking, and they also resist any tendency of the bar to warp or bend. The inclined braces are supported at intermediate points by vertical bars 8 and 9, connecting the braces with the bar 1 and cooperating with the said braces and the `loar to forni a truss. The vertical connecting bars 8 and 9 operate in the nature of struts,

and they also serve to support a pivoted level bar 10. The level bar 10, which is equipped at the center with a spirit level 11 is pivoted at its rear end in a recess 12 of the rear vertical bar 9 by a pin 13, or other suitable fastening device, and its front portion operates in a vertical slot 14 of the front vertical bar 8, and it is secured in its adjustment by means of setscrew 15. The front vertical bar 8 is provided with a plurality of threaded perforations 16 for the reception of the set screw to increase the range of adjustment of the pivoted level bar, which is adapted to be arranged either in a horizontal position, or at an inclination to adapt the instrument for surfacing either a level track or a track having a grade. The pivoted level b ar operates as an in clinoineter, and it is adapted to be arranged at different angles or inclinations, a suitable scale 17 being provided t-o facilitate the adjustment of the level bar. The front end of the pivoted level bar is raised and lowered in the slot to adjust the said bar 10 with relation to the 1car 1.

The front end of the longitudinal bar 1. is reduced to form a tongue 18, which is secured in a slot 19 of a transverse level bar 20, arranged to extend across the track, and equipped at the center with a spirit level 21. The outer end of the transverse'level bar 2O is provided at its lower face with an inclined series of horizontally disposed shoulders 22, arranged at different elevations and adapted to enable the outer end of the transverse level bar to be raised and lowered with relawill enable the rail, upon which tl're Louter end of the transverse bar is placed, to be arranged at different elevations with relation to the other rail. The adjustment of the level bar 20 transversely of the front end of the longitudinal bar l enables any one of the notches of the bar 2O to be placed in position to rest upon the contiguous rail. This adjustment also enables the device to be employed for surfacing vtracks of different gages. The slotted end of the transverse level bar 20 is securedon the front end of the longitudinal level bar by -means of a vertical 'pin 22a, piercing the tongue and engaging the front face of the transverse level bar. This permits the transverse level bar to be readily shifted transversely of the instrument, but any suitable means may be employed for positively securing the transverse level bar in its adjustment with relation to the longitudinal level bar. Y

Preparatory to the use of the surfacing level, ythe track at onev point is raised ashi'gh as it -is `wished to surface the track. Then the surfacing level is f laced n the track with the longitudinal 'eval bar, extending lengthwise of ene of the rails and the outer end of Lthe transverse level bar resting uV on.

the other rail. The track jacks are tien placed one lon each side of the track at the front end of the instrument to which bar 20 is attached, and the track is raised until it is level or at lthe proper inclination. rlhe instrument is then moved vsixteen and a half feet ahead, the rear endof the longitudinal level bar lbeing placed at the point previously occupied by the front end of the same,r and the operation isrepeated. 1f the track foreman should not know the per cent. of a gracle to be surfaced, it can be easily ascertained by sighting over the level to a point ahead, and setting the level accordingly.
