4 Claims.

This invention relates to improvements in derailing devices and has particular reference to portable turn-tables adapted for easily and quickly'de-ralling trucks of any nature, such as rail grinders, light weight repair cars, hand-cars, and. the like, upon the approach of a train. An object of the present invention is to provide a de-railing device of simplified construction, low in cost, adapted for quantity production, simple to assemble, and of suflicient strength for its purpose.

A further object of this invention is to provide a de-railing device easily transported and which is not cumbersome or heavy.

Another object of this invention is to provide a de-railing device which can. be handled by one man.

Still another object of the present invention is to provide a de-railing device adapted to be made from standard steel shapes with a minimum of machine work, which may be assembled and disassembled completely with the use of but one bolt, and which provides marked commercial and mechanical advantages over derailing devices heretofore used.

With the foregoing and other objects in view, as will be apparent as the description proceeds, my invention resides in the combination and arrangement of parts and in the details of construction described in this specification and particularly pointed out in the appended claims, it being understood that changes in the particular embodiment of my invention maybe made within the scope of what is claimed without departing from the spirit of the invention. I intend no limitations other than those of the claims when fairly interpreted.

Referring now to the accompanying drawings which are furnished solely for illustrative purposes,

Fig. l is a sectional elevational showing a preferred form of my de-railing device, the section being taken on the line A-A of Fig. 2;

Fig. 2 is a side elevation of the device of Fig. 1;

Fig. 3 is a perspective sketch illustrating details of construction of the device of Fig. l; and

Fig. 4 is a plan view of the device of Fig. l on a pair of rails, with the turn-table turned part way around towards derailing position.

Similar reference characters refer to similar parts throughout the views.

Turning particularly to Figs. 1 and 2, the track on which the de-railer operates comprises the rails 3, 3, on the usual tie- plates 2, 2, and

ties I, I. A main frame is provided to extend across the track comprising, in this instance, a lower support member 5 and. an upper turning member 6 loosely pivoted to the lower member 5 as bya bearing block I2 and a bolt 9, or in any desired manner. The lower member 5 may be supported slightly above the surface of the rails by two longitudinal side members 4, 4, preferably standard angles bowed slightly upwards at the center, and resting on the rail heads 'at the ends, insulation blocks I3, I3, intervening when desired to avoid short circuiting signal or other currents. To prevent side slip of the frame, I. prefer to provide stops or hooks I, I, on the lower support member 5, normally insulated therefrom as at 8, and arranged to engage-the under side of the rail heads on the inside; as showniin-Fig. 1.

Engaging the upper turning member 6, supported thereby, and turning therewith, are two longitudinal track members II], II), which are bowed upwards at the center and provided with insulation blocks I3 at the ends. Preferably these members are standard angles, each with the vertical leg chamfered off towards the ends as indicated at I4 (Figs. 2 and 3) in order that the truck to be de-railed may more readily roll up and down on the members In, II].

It will be noted (Fig. 2) that both ends of each longitudinal track member I0 do not touch the rail head simultaneously but that these members, together with the upper turning member 6, rock slightly on the bearing block I2, so that when the truck to be de-railed rides upon the track members I0 and balances, the said members will swing clear of the rails and may also be swung over the chamfered vertical legs of the side members 4, 4.

Attention is directed to the sketch of Fig. 3, to show more clearly the simple method of interlocking assembly of the parts described. Support members 5 and 6 are preferably standard rolled shapes, in this instance being channels, and after being bolted together are not normally taken apart. In the simplest form of construction, as shown, the two channels 5 and 6 are loosely boltedtogether at the center with a bearing block I2 between them, the upper channel 6 being downwardly curved, if desired, to provide bearing at the ends.

The side legs of each of the channels 5 and 6 are vertically cut out and horizontally slotted, as at II, so that the longitudinal angle members Ill and 4 may loosely interfit, each with its respective channel, and be held against unintentional side movement or lifting. In the case of lower angle 4, the vertical leg of the angle is cut away to accommodate the width of channel 5.

In dis-assembling, each angle may be quickly twisted out of its retaining slot H by a rolling motion of the angle, some play having been provided in the vertical out. When assembled, however, the flanges of the truck wheel's prevent play of the angles and thus prevent the angles from disengaging the slots l I.

It is apparent that, when not loaded, angles 10 and 4 may readily be disengaged from channels 6 and 5 and the entire apparatus may be demounted from the tracks by-one man in a few seconds. In transportation, the four angles and the joined-together main frame; comprising channels 5 and 6, may be nested and bundled together in a long package of small cross section which may be readily handled and easily assembled again. In operation, the truck to be de-railed is rolled from the gauge rails directly up on track members l0, l0, chocks placed if desired, and the whole upper turn-table comprising the cross member 6 and the two track members HI, ID, may then be swung around at right angles to the gauge rails, the chocks removed and the truck run oil to either side. The de-railing device may then be quickly dis-assembled and removed from the gauge rails. To replace a derailed truck upon the gauge rails, the reverse procedure may be followed.

What I claim is:

1. In a de-railing device, a main transverse frame comprising two frame members pivotally connected together one above the other, longitudinal side support members removably interlocked with the lower one of said frame members oted to and positioned above said first mentioned frame member, and two longitudinal track members removably interlocked with said second frame member and pivoting therewith.

3; A de-railing device comprising two channel members pivotally connected together one above the other, a pair of angle members removably interlocked with and supporting the lower one of said channel members crosswise above a railroad track, a second pair of angle members removably interlocked with the other of said channel members and pivoting therewith.

4. In a de-railing device, a stationary frame comprising a transverse member and two longitudinal upwardly bowed side members removably interlocked with said transverse member adjacent the ends thereof and adapted to rest at their ends on railroad rails, a second transverse member pivoted to and positioned above the first named transverse member and having bowed down ends adapted to rest on the first named transverse member, longitudinal track members removably interlocked with said second transverse member adiacent the ends thereof and adapted to be positioned above and aligned with said side members for reception of a truck to be de-railed.
