The invention relates to a' quick releasable light portable derailsuited to a wide ran 'e of rail sections havin an ad'usta'ble road-bed-contacting thrust=receiving membar dividing the vertical wheel thrust with the derail block a quick appliable andqui'ckreleasable adjustable clamping jaw "and other distinctive features pointed out in the following specification or made apparent to those skilled in the art. These structural cl'mracteristics though novel and of value individually are advantageously combined in the preferred form ofinvention shown in the accompanyingdrawings, in which- F 1 is a side elevation of thederail in released position;

Fig. 8 is a detail plan showing the slot and countersink in the top of the derail body, and r Fig. 9, an end elevation of the clamping jaw looking away from the rail.

,Rapidity and ease of application and release are a. primary characteristic of this derail. Whenonce adjusted for a given rail section, it may be applied thereto or released therefrom, as will be hereinafter explained in detail, mainly by a single rapid n anual movement which is supplemented by bringing power applying means very briefly into play to merely finish the clamping movement or begin the release movement, the application of power being rediv ed to the minimum. As portable 'derails must oftenbe removed and replaced-- usually under conditions requiring hasteand always where speedand ease'of application and release are desirableythis char acteristic is of vital importance.

The derail has a bearing on the top of the rail, a bearing on the road bed and a bearing on the underside of the head of the rail ustable up against the underside of. the rail head and thereby exerting downward. pressure on both of the other bearii'igs and clamping the derail on the rail. The derail illustrated has the derailing member consisting of the body 1 and derail block 2. having usual wheel-derailing contours made as one casting recessed on the underside for lightnessand to provideroom for and to protect moving parts, andan adustable thrust-rece ving road-bed-abutting member, the screw bolt[3, 1: assing down throughthe body and adjustable in'the fixed removable nut 4 thus dividing the vertical wheel thrust with the derail block and pro, vidin for vertical adjustment to suit'rails of heights both greater and less than those shown. The tail of the body ay itself rest onrthe tie where the rail islowenough. The. derail block has in its underside a rail-headreceiving recess which sets down onto the rail head but is wider than the rail head to suit rails of different cross section. T he depending flange 5 on the derail block forms the outer wall of this recess between which and the clamping jaw 6 the rail head is clamped. This aw is mounted in the under-' side of the body of the derailing member at one s de of the recess for quiclrmanual movement under or out from under the rail head and for camming by a brief application.

of pow-er up against the underside of the rail head into clamping position by movement relative to inclined ca/m surface on the derail body as will be hereinafter explained.

The clamping jaw in the illustrated derail is a floating jaw being loosely mounted as to be capable of .movement in various directions, and in this embodiment of the invention it is also a lever having turning movement aroun d its fulcrum whose position changes. For greater effectiveness in clamp-' ing the jaw 6 is constructed with two distinct camming and clamping members spaced apart lengthwise of the rail but integrally united by the jaw body which is designed by longitudinal, transverse and upright connecting walls to afford a structure braced against the considerable strains to which it is subjected, and capable of housing certain of the parts and whose end walls 7, She in planes transverse of the rail and f by outwardly projecting flanges, provide twoupwardly facing correspondingly curved bolt 15 prevents the nut and the jaw from.

tracks

9, 10, shown as rockers curved lengthwise on the arc of a circle and having their rear and front ends suitably rounded as indicated respectively at '11, 12, for sliding contact of the portions 11 with upwardand" railward cam inclines, the ribs 13, '14, and for resultant clamping contact ofthe portions 12 with the rail. To avoid useless and annoying projections and for, convenient support when not assembled the jaw. 6 has the bottoms of its end walls flat and in the same horizontal plane below the rest of the jaw. The jaw is releasably and adjustably supported in the body 2by the supporting,

adjusting and clamping screw bolt 15 passing downward and railward through the elongated slot 16, whose railward end s-surrounded by 'a countersink 17 cooperating.

with the bevel 18 of the head'19 of the bolt 15 to form bearing means supporting. the bolt when at the railward end of'the slot, as it is in the clamping operation, andto preclude possibility of derail release by pushing the bolt with the restof the movable clampingstructure backward when in clamped. ositionu The bearings afford the readily occurs, thus further promoting the flexibility referred to. It is held against rotation by

upright walls

21, 22, 23 of the jaw body which forms a rectangular recess open at its railward end for insertion and removal of the, nut, under which lie the flange lugs 24, 25 which receive the thrust of the nut while the screw bolt 15 is turned reversely in releasing and whic'h project to- "ward each other from the parallel walls 21,

23. A cotter pin 26 in the end'of the screw falling off the bolt under any circumstances. Between the nut and the underside of the jaw body is a split spring washer 27 pro viding a lost motion connection to permit backing off of the screw bolt 15. after clamping for purposes hereinafter explained, It

will be observed that in the illustrated dc rail the a-Xisof the adjusting screw bolt intersects the plane of the cam-inclines, ex-

tending downward and railward whereas the said plane extends upward and railward.

-The endwise or railward movement of the clampin jaw is thus doubly insured. The hole'midway of the end walls of the jawbody through which the bolt-15-passes has its center in rear of the 'central transverse plane of the jaw. Spaced a little behind the hole and the screw bolt therein is an upstanding abutment 6' which furnishes leverageenabling the bolt 15 which acts against it in the rearward movement to release the clampingja-w when stuckrto the body each end lengthwise of the rail and it and adjacent parts of the raisedtop of the body of'the jaw extend back' into the space heof the derail. The projection 6 is bevelled at tween the cam-inclines when the parts are in the released position. Further means of support for the jaw and parts connected therewith effective when the jaw is screwed well down on the bolts 15 is provided'in the

"of thejaw body and oncwhich the undersides 30,31 of the times rest. V

As indicated in Fig. 1, which shows the jawbody flanges may at derail betweenthe rails adjusted to suit the i rail section, the adjustable thrust-receiving bolt 3 also acts at full release as a support for the jaw-adjustingscrew bolt 15 and connectedpartsjthe head 19 of the latter being in contact with the eye 3 of the former, both ends of the clamping jaw being then free, though the parts of the

tracks

near the far end of the jaw may rest against the adjacent cam inclines. The derail having been so far applied as shown inthis figure all that remains to be done toclamp it to the rail is to pull or shove the bolt 15 with associated parts-upward and forward to its bearing in the countersink 17, which may be'done bya single quick manual movement, the principal shift of the jaw being 7 thus accomplished the

tracks

9, 10 being moved along the corresponding cam inclines 13, 14, and to complete the clamping by giving thebolt 15 a few turns, which may readily be done by means of handle 32, whose spaced end lugs embrace the flattened head end of the bolt to which it is swivelled at This turning of thebolt 15 exerts a pulling or drawing effect on the clamping jaw and carries the front end of the jaw up into final clamping position under the rail head, the rear parts of the jaw which abut on and are movable with respect to the inclines assisting in this, operation. In this position the

tracks

9, 10 by their front ends 12 and adjacent surfaces, at the same time contact both the web and the underside of the ball of the rail, the loose mounting of 'the aw permitting it to accommodate itself to these rail surfaces; Byvirtue" of the duplica te camm-ing' and: clamping members, this action occurs at two points spaced: well apart along theraila Theclamping action is thus firm and: positive and precludes sliding The spring; washer 2'7 preserves the clampingwefi'ect and admits of backing oilthe screw bolt so as to register the slot 32- of. its handle with the eye 3 of the adjustable thrust-receiving,bolt3 and permit it to pass over the eye and be'locked in clamped position by padlock 34 passed through the: eye and whiohmay be chained to the tie. But the pad loclr is not required to maintain the jaw clamped. Quick derail release is effected by reversing, the mode of derailapplying, and clamping above described. A few reverse turns of the screw bolt 15" provide sufiicientp-lay to enable the bolt with attached parts to: be pulled up and thrust back, the-bevel 18 of the bolt clearing thecountersink', which is done by a single member having. a unitary deraili manual upwardaand backward; pull or jerk, theparts once the countersink has been cleared falling downward and backward by gravity or assisting this movement by their weight. At the heel otthe derail block slot 35 designed to receive a banner stafl passes through the hand hold- 36. tend down at each end of the slot.

The range'of adjustment, division of vertical wheel thrust, efiicieney of the clamping,

speed of application andsrelease with mini mum power movement, capability of backing of]? in clamped position without impairing effectiveness of the clamping, locking, and the seeuri'ng'of' all these advan tages in a small light derail are meritorious and novel features characteristic oli'this invention.
