LEVEL.

Specification of Letters Patent.

Patented Oct. 15, 1912.

Application filed September 20, 1911. Serial No. 650,450.

To all whom it may concern:

Be it known that I, JAMES D. GUILFOYLE, a citizen of the United States, residing at Titusville, in the county of Brevard and State of Florida, have invented a new and useful Level, of which the following is a specification.

This invention has. reference to improvements in leveling instruments for track laying and is designed more particularly for use by track foremen in surfacing and lining track, as well as for other uses.

When railway track rails are laid or rep1 red or other work is done on the track,

it is customary for the track foreman to get down on the ground alongside of the track in a manner to bring the eye close to the track in order that a considerable, length of track may be brought in line with the eye and such changes in level or alinement of the track'be made as may be necessary. In order to facilitate such surfacing and lining of the track it has been proposed to employ a block or board with a sight-hole therethrough at a certain distance above the track to approximately conform with the distance of the eye from the track when the head of the observer is close to the track rail. In combination with such device having a sight-hole there is provided a target movable along the track and this may be utilized in conjunction with a track-board appropriately marked so that the lining or surfacing of the track is facilitated. In all instances, however, it is necessary for the foreman to bring his head close-to the track, and this means that the foreman must kneel upon the ground and bring the body close to the ground, this operation if frequently performed becoming Very tiresome. With the present invention the same operations of surfacing and lining of the track rails may be performed without the necessity of the foreman kneeling and bending the body to bring the head low, and in fact need not bend the body more than is necessary to permit the gaze to be directed downwardly.

' To this end the invention comprises a boxlike structure lncloslng an inclined mirror with sight-holes properly disposed with re-.

lation to the mirror, such sight-holes being covered by glass or other transparent plates upon which are produced indicating marks. The arrangement is such that the box-like body of the device may be readily secured track-board downward upon the ror visible through what is then the upper glass plate, the vision is diverted by the mirror so that the line of track at what may be termed the front of the device is visible in the mirror, and by bringing the indicatmg marks on the two glass plates into coincidence and employing the usualtarget and may be further provided with a level, where by leveling of the track or of other devices is readily accomplished.

Devices of this character are liable to rough usage and to provide for convenient assembling and repairs the body of the structure is made in two parts which may be identical one to the other, except that one is a right hand member and left hand member, and these parts are so constructed that when placed together with the glass plates and mirror in their proper places, the securing devices for the two parts of the body also constitute securing devices for the mirror and the glass plates. Moreover, in order that the device may be held to a track without liability of displacement, gripping or clamp devices are provlded and the track rails may be adjusted to the desired position Without danger of disturbing the relation track rail upon which it is placed.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that while the drawings illustrate a practical embodiment of the invention, the latter is susceptible of other practical embodiments retaining the salient features of the invention, and consequently the invention is not limited to any exact conformity to the showing ofthe drawings.

In the drawings :Figure 1 is a perspective view of the device of the present invention applied to a track rail. Fig. 2 is a to a track rail and then by gazing directly device so that the mirthe track may be brought to the other a of the device to the longitudinal section on the line of division between the two parts of the body of the structure. Fig. 3 is a section on the line 33 of Fig. 2 with the mirror and its supports shown in plan. Fig. t is a section on the hue t -lof? Fig. 2. Fig. 5 is a section on the hue 5--5 of Fig. 2.

Referring to the drawings there is shown her of such size is sufliciently long and the cross sectional size does not prevent the ready carrying of the device in a coat pocket. The body member is made in two parts meeting along the ,center line ot the completed body me1r er, and the walls of the parts are. made quite thin for the sake of lightness, so that ii -the entire structure be made of aluminum the weightis negligible, and even if made of heavier material the weight is even then'not excessive. Considering one end of the structure as the front end, this end is provided with an opening 2 formed by inturned flanges 33 and the top of the structure is formed with an opening 4t which is spaced an appropriate distance from the front of the body member and does not reach quite to the sides of the body member, thereby providing m'erhanging flanges 5 defining the sides of the opening-la Each half of the body member has formed on its side member on the inner surface thereof an instanding flangcfi, adjacent but spaced a short distance from the corresponding flange 3 and also another flange member 7 similarly located with reference to the corresponding flange 5, and what constitutes the rear end of the flange 7 is beveled as shown. ate. Also :torn'ied on the inner face of each side ofthc hall member ot the body 1 another flange 9 inclined with relation to the top and bottom of the body llltl'lll-ltl at an angle of iortyfive degrees, and this flange 2) extends from a point u ar the to of the corresponding hall at the body memher 1 to a point near the bottom thereof, the upper end of the llaugc 5) being spaced an appropriate distance back of too beveled end 8 of the flange 7. In front of the lower end of each flange 9 there is formed an out.- standing elongated stud 10 parallel with the flange J and spaced therelr m a di lance approximately the same as the distance be tween the beveled end of the llange T and the corresponding end oi? the ilauge 9.

the two body members are secured together by rods 11, one near the trout and the other near the rear, but this does not preclude the use 01 more rods, if desired. The rods are shown riveted at the ends, but it will be understood that other fastening means in place-oi riveted rods may be employed.

\Vhen thetwo halves of the body member are assembled, a mirror 12 is lodged on the @flanges 9 and held against movement by the beveled ends 8 of the flanges 7 and the studs 10. The openings 2 and il are covered by glass plates 13 and 1 1-, respectively, lodged between the flanges 3 and 6 and between the flanges and 7, respectively. Produced uponthe plate 13 is an indicating mark 15 and produced upon the plate let is an ind'cating mark 16 and both of these marks may be in the form of a line out into the plate and filled with ptigment or produced in any suitable manner, a ime being the form of indication best adapted tor the purposes of the invention, although indications other than in the form of a line may be employed. The lines 15 and 16 are so related that the line 15 will be at a predetermined distance above the bottom of the body member and the line 16 will coincide with the reflection of the line 15 in the mirror 12 when the angle of incidence and the angle of reflection define an angle of ninety degrees, the mirror 12 being set at an angle of forty-tive degrees to the planes oi the plates 13 and 14., and these latter plates being set at an angle of ninety degrees one to the other.

The side and top members of the body 1 are contracted near the rear end of the body member as indicated at 17, thereby defining .tinger spaces for a purpose which will present'ly appear, and these contracted portions unite in a ridge 18 rising to the level of the top of the body member, and in this ridge is formed a. socket 19, one half of the socket being formed in one half of the ridge, and

the other half in the companion half of the ridge, the central division line of the body member extending longitudinally and contrally through the socket 19. At the top of the ridge the two body members are formed with openings coacting to constitute a sightopening 20, whereby the interior of the socket may be viewed, and this socket is designed to contain a. level glass 21 of appropriate vt'orm which may be held in place by a plug 22 iutroducml into the rear end of the socket, which is initially formed open for the purpose. .ltis customary to make the plug of plaster oil Paris or some sue-.1 material. but any approyn'iate plug may be employed, the purpose being to confine the level glass 21 in position in such manner that when the body member is level the large bubble in the glass central to" the opening 2. or to a suitable indication on the level glass.

The tread of a railway rail does notconstitute a very certain support for a structure of the character herein described and shown in the drawings, but for efficient use the device should be firmly held to the rail and at the same time be readily detachable I body member oted to the rear end of the body member two grip levers 23, 23, on opposite sides'of the center line, and these grip levers are held to the body member by pivots 25. The levers are shown as of the first order, each with one arm constituting the upper arm when'the formed-into a finger seeker 1ng to separate the finger ends of the levers and cause the gripping ends of the levers to approach, excesslve movements of the levers under the action of the spring being prevented by stop studs 30 which may be formed on the rear end of the body member. The fingtr ends 26-of the levers are long enough nd so disposed as to be accessible from th contracted-portion 17 of the body member.

When it is desired to apply the device to a rail the finger ends 26 are caused to ap-- proach by being suitably grasped by the fingers of the operator and the sprmg 29 iscompressed,

thus separating the ends 27 of the levers, which ends be readily placed over a track rail, the latter being indicated at 31 in Fig. 1. The fin ger ends 26 being now released the expansion of the spring 29 will cause the gripping ends of the clamp levers to clasp the tread of the rail in a manner to firmly hold the lagainst displacement on the rail while resting on said rail and the clamp members also tend to aline the body member with the rail.

It will be understood that the various expressions of position hereinbefore used are with relation to the operative position of the structure on a track rail and the terms front and back or rear are used with reference to the line of sightin the-use 0f the device.

Let it be assumed that the body member 1 is restingon a-track rail in alin'ement therewith, being secured to the track rail by the clamp made up of thegripping levers and that itis desired to surface or line track rails in advance of the device in the direction of the line of sight through the plates 13 and 14 and by way of the mirror12, The track board may be placed in proper position upon the rail to be surfaced or lined and in the case of surfacing, the usual small target is placed upon the rail, theline 15.

being at such a height above the rail upon which the body is supported as to conform. to the height of the target. Now by sighting through the plate 14 and bringing the lndication 16 into coinciden'ceQwith the indi-,

cation 15, the rail carrymg the target may be elevated or depressed until the target is gripping may then forming closures for brought into proper relation to the usual mark upon the track board, and this may be done without the necessity of the track fore man kneeling down at all, for the track foreman need but to stand in position to gaze lown through the plate 14 to ascertain when the proper surface elevation of' the railbeing operated upon has been reached. vFor lining the track foremanhas but to gaze as before through the plate 14 when thereflec; tion of the line of .rails will be seen in the mirror 12 and lack of alinement of these.v

rails 'is readily ascertained. The leveling portion of the device isutilized in the usual manner and needs no special description.

By making the body member of two parts no special fastenin devices or provision for the introduction 0 the glass plates and the mirror are necessary and all parts of these members except those purposely visible, are completely covered'or housed. Should the fragile parts become broken,

the fastening devices 11 may be removed and the broken parts are readily replaced by new parts without the necessity of any special skill in reassembling the parts, since the seats for the glass members will automatically position the parts at the proper angle. 7 L
