RAILROAD CROSSING GATE Filed April 15, 1929 2 Sheets-Sheet 2 9 9 O O O 0 b O O O O 0 In venior Patented Dec. 24, 1929 UNITED STATES EDWARD L. IRSIK, OF INGALLS, KANSAS RAILROAD-CROSSING GATE Application filed April 15,

The present invention appertains to improvements in railroad crossing gates and more particularly to a gate of the type operated by the rolling stock.

The principal object of this invention is to provide a railroad crossing gate which will be entirely automatic in operation.

Another important object of the invention is to provide a crossing gate which, in opera- 1 tion will be positive acting and which, be cause of its simple construction, will not readily develop defects.

These and other very important objects of the invention will become more apparent to the reader after considering the invention as described and claimed hereinafter.

In the drawings:

Figure 1 represents a top plan view of a railroad crossing showing the roadway and track equipped with the improved mechanism.

Figure 2 represents a longitudinal sectional view through one of the gate structures.

Figure 3 represents a transverse sectional view through the said gate.

Figure 4 represents a side elevation of the operator and fragmentarily showing the buffer of a locomotive, with means engageable therewith.

Figure 5 represents a side elevation of the catch release, the same showing the opposite side from that shown in Figure 4.

Referring to the drawings, wherein like numerals designate like parts, at each side of the track rails 55 and extending transversely of the roadway 6 is a gate mechanism generally referred to by numeral 7. Each gate construction consists of an elongated housing 8, provided with a removable top cover 9, which is adapted to lie substantially flush with the surface of the roadway 6. The plate 9 is formed with the longitudinally extending slot 10, while a bar 11 is supported at its ends by the end walls of the housing 8 and is located slightly beneath the top plate 9. To the bar 11 are pivotally connected fingers 12, which are pointed at their upper ends and allowed to protrude through the slot 10 when in upright position. These fig- 50 ures are pivotally connected to the bar 11 as 1929. Serial No. 355,321.

at 13 and at their pivotal ends, the fingers 12 are provided with obliquely disposed stems 14. A slidable rod 15 "is slidab'ly disposed through an opening 16 in one end of the housing and has pivotally connected thereto the free ends of the stem 14. A log 17 depends from the rod 15 and has an offset portion 18, adapted to be engaged by the head 19 of a rockable catch member'20.

A rod 21 is pivotally connected as at 22 to the opposite end of the rockable member 20 and extends through an opening 23 in the opposite end wall of the housing 8. A coiled spring of the expansible type is designated by numeral 24, and tends to normally maintain the fingers 12 in retracted position.

The bar 15 connects to the rocker 25. A connecting link 26 extends between the rocker 25 and a second rocker 27, while a rod 28 is pivotally connected at one end to the rocker 27 and at its opposite end to the lower end of a. vertically disposed rockable lever 29, which is adapted to be engaged by the arcuate arm 30 on the front of the locomotive generally referred to by A. The rockable lever 29 is mounted upon a suitable upright 30 in the manner as shown in Figure 4.

The rod 21 is connected to a cable 31 which is trained over a pulley 32 and led to the lower end of a rockable lever 33, mounted upon a c suitable support 34 for a rocking motion on a plane transverse to the track rails 55, whereas the lever 29 rocks on a plane parallel to the rails 55. It will thus be seen that when the arcuate arm 30 engages the lever 29, the movement of the lever will move the fingers 12 into the position shown in Figure 2. The lug 17 will have its offset 18 engage the head 19 of the catch 20 and thus retain the fingers in upright position even though the lever 29 is released. The arm 30 will afterward engage the rockable lever 33 and move the outer end thereof outwardly so that the lower end thereof will exert a pull on the cable 31 to release the rockable catch 20 and permit the fingers 12 to retract.

The mechanism has been shown in duplicate so as to operate the gate by a train moving in either direction.

While the foregoing description has been in definite terms, it is to be understood that various changes in the specific shape, size and materials may be resorted to, Without departing from the spirit or scope of the invention as claimed hereinafter.

Having described the invention, What is claimed as new is:

A railroad crossing gate comprising a housing embedded in a roadway, a plurality of pivotally mounted and normally concealed members arranged Within the housing, track means for elevating the said members to protrude upwardly from the housing When engaged by rolling stock, latch'means for retaining the pivotal members in elevated position after the rolling stock has released the said track mechanism, additional track mechanism for releasing said retaining means after the rolling stock has passed the road- Way, and spring means for retracting the pivotal members.

In testimony whereof I aflix my signature.

EDWARD L. IRSIK.
