Application led January 23, 1919, Serial No. 272,670. Renewed Rovernber 28, 1921. Serial No. 518,431.

T 0 all whom 'it may vconcer-n.'

Be it known that I, STANLEY W. HAYES, United States citizen, residing in Richmond, county of Wayne, Indiana, have invented the following described Improvements in Derails. Y Y i The invention provides a light weight derail that can be conveniently thrown either by hand or pipe-line and consists in the structure of the derailing member and its relation Yto theguide box or base and in the organization therein of a hand operated power-'multiplying mechanism as hereinafter ,explained andmore particularly pointed out in'the claims. VIn the drawings- Fig. 1 is a side elevation of the derail on the .rail. A l A Fig. 2 'is a partly sectional elevation of 'the same derail partly Withdrawn.

` Fig. 3 is a side elevation of the rail,

Fig. 5 a rear View partly in section showing the rear bearing.'

The base member comprisestwo upstanding side wall portions 1, united by lower cross wall portions 2 and 3 the latter provided with exterior spike flanges i adapted to be spikedto two adjacent ties. rl`he base is open, having no uppercrossbar or roof member, and the interior is'occupied by the derailing member, which latter is mounted on forward and rear bearings therein so that itV advances horizontallyv to the rail and withdraws therefrom,'iirst,with an upward and then with a downward movement, its withdrawn or open position being depressed at oneoside of the rail. The derailing mem ber comprises the body or supporting part 5and the derail block 6 and is cast in one piece and hollow on its under side for lightness and to provide accommodation and shelter to the rear bearing and subjacent parts. The forward bearing is provided by two studs 7 projecting laterally from the .lower end of the shoulder structure 8 at the forward end of the body part of the derailing member, near the derail block2 and sliding fn, grooves 9 formed in the inner faces "of the sides 1. rllhese grooves are curved to give the derail block the up-andover movement above mentioned and their engagement with the studs also serves to hold Ithe derailing member against upward displacement. This particular lform of forbase lug 12 and von the other, by the undercut base lug 13, the structure of which overlaps a side rail 14 on the rib 10 to keep it 'from upward displacement.v Such rear'rib bearing is central between the vertical planes of the'two forward bearingstuds i7, and thereby prevents cram-ping of the member in the'base, while the vertical curvature of the rib contributes a desirableV additional vertical component to the motion ofthe lderailingmember, designed te keep the operating lug 15, and hence the pipe-line rod 16 attached thereto, at a substantially conf stantlevel in all positions, and otherwise to facilitate the movement of the member as will b e apparent, The saidoperating lug 15 is cast on the rear of the body 5, and eX- tends downwardly to a point below the level of the cross walls 2 and 3 so that the pipeline when used, may run as usual beneath the rail. The derail' shown may also be provided with a duplicate attachment lug 17 (Figs. 4L` and 5) 'for connection to a target staff or other track appliance or connection as desired.

For d'rect hand operation, theV derail is provided with a power-multiple device in the form of a hand lever 18 fulcrumed on a lower stationary support, for instance upon the lug 19 projecting from the forward side of the cross wall 3 and having a bearing on the derailing member preferably at a central point thereof and by means of this lever 'the heaviest sizes of derails may be thrown with little effort.I The preferred form of operating mechanism is a' lever of the second class as shown, passing through a hole 20, in the forward center of the body 5, and curved in a fore and aft direction so that it can occupy a substantially horizontal position when the derail is off the rail. Derails are commonly placed between the rails of the track and the lever 18 is therefore in this manner arranged to be out of the way of passing rolling' stock when the derail is open, .while when the derail is closed the hand lever is upstanding and may serve as a signal device depending on its length. The curvature of the lever is preferably formed in that part of its length which engages the bearing represented by the rounded edges of the hole 20, and thereby it acts with a camming effect on the derailing member, further multiplying the power effect thereon which is particularly useful in raising it'from its depressed position against obstruction by .frost or other cause. Such camming effect is supplementary to the primary function of the-'lever and due to its curvature but the invention contemplates the use of any power-multiplying mechanism as a means of enabling largesized and heavy derails to be directly thrown by hand by an operator standing at the derail. Such mechanism may however be omitted when the derail is to be operated solely by the pipe-line, but the structure is preferably manufactured with the fulcrum lug 19 and with the other lugs l5 and 17 upon it in any case, so that itV may be sold for use either way.

The two mainv parts of the derail are assembled by placing the derailing member in the bas'ein a` position slightly forward of that indicated in Fig. l, and before the base is spiked to the ties and then introducing vthe rib 10 and studs 7 into their yrespective bearings and sliding them rearwardly therein. When the base is thereafter secured to the ties the obstruction represented by the adjacent rail-head confines the derailing member in its bearings vas will be obvious.v The rear end of the side wall portion is provided with a perforated' ear 23 and the derailing member is formed with two abutment surfaces 2l and 22 so that a padlock hasp inserted through the ear will coact with either abutment to lock the member either opened or closed.

It should be noted that the studs 7 are located at the eXtreme forward end of the base and are therefore close to the rail when the derail is open, in which position their function of holding the block against kicking up on wheel impacts is most eective, being thereby freed from much of the leverage effect that has heretofore been present in derails having the sliding movement above described. This result is obtained by forming the said studs 7 at the lower ends of the shoulder structure 8 directly under the derail block 6 instead of on the sides of the body part 5 of the derailing member,

Vvand it i's manifestly independent of the 60v specific manner ofv sliding support.

Claims: *Y l. A derail comprising a base, a derailing member mounted thereon on forward and rear-bearings, the rear bearing formed by a central rib depending from the said member and sliding on andV confined to a central bearing surface onsaid base.

2. VA derail comprising an open base7 a derailing member mounted thereon on a forward bearing imparting up-and-o-ver movement thereto, and on a rear bearing comprising'a central rib dependingV from said member and sliding on and confined-to a bearing surface on the base.

3. A derail comprising an openbase member, a derailing member mounted therein on forward and rear bearings, the rear bearing comprising a rib on one of said members sliding on a bearing surface in anundercut recess formed in the other member and held thereto by the undercut formation.

4f. A derail comprising a base and a de-i railing member having a depending web or rib with a curved lower edge sliding on a bearing surface formed on the base.

9. A derail comprising a base, and a derailing` member adapted to occupy adepressed position at the side of the rail, combined with a hand lever by which the member may be moved, said lever being organized with said base and member to move to a substantially horizontal position when moving the membery to said depressed position.
