FOLDING CAR-GATE.

SPECIFICATION formingpart of Letters Patent No. 692,985, dated February 1 1, 1902 Application filed April 6, 1901. Serial No. 54,721. (No model.)

To all whom it may concern.-

Be it known that I, NICHOLAS H. OoLwnLL, a citizen of the United States, residing at Pawtucket, in the State of Rhode Island, have invented a new and useful Improvement in Folding Oar-Gates, of which the following, is a specification.

In cars employed upon elevated and other railroads it is very desirable to provide a folding gate which may be opened and closed within a very little space, so that the crowding of passengers upon the platform will not interfere with its operation; and my invention consists in the improved combination of a folding gate with the gate-operating means, as hereinafter set forth and claimed.

1n the accompanying drawings, Figure 1 represents a top view of a car-gate embodying my improvement and showing the gate in its closed condition. Fig. 2 represents a vertical section taken in the line 2 2 of Fig.

. 1, showing a side elevation of the folding gate-operating means.

gate-sections. Fig. 3 represents a section taken in the line 3 3 of Fig. 1, showing a side elevation of the supporting-frame and the Fig. 4: represents a bottom edge View of the closed gate. Fig. 5 represents a bottom edge view when the gate is nearly closed. Fig. 6 represents a bottom edge view showing the gate in its opened condition.

In the drawings, A represents the front portion of the car-body, B the platform, and O the supporting frame or grill to which the gate D is pivoted. The lower end a of the pivot-rod b of the rear gate-section 0 extends downward into the perforation d in the step e, while the upper end of the said pivot-rod is held in the perforation f in the bracket g of the supporting-frame C. The forward gatesection his hinged to the rear gate-section c by means of the pivot-rod 7 whereby the gatesections it and 0 may be made to fold upon each other in opening the gate, as shown in Fig. 6. To the lower edge of the gate-section h is pivoted the link j at the point is, the opposite 'end of the link being jointed to the lever Z, which is pivoted to the lower edge of the gate-section c at the point m, the said points is and m being located about equidistant from the line of the axis of the pivot-rod z', the lever Z and linkj serving to form, with the gate-sections to which they are pivoted, a lazy-tongs movement, by means of which the proper opening and closing movement of the gate may be effected. The hand-lever E is pivoted to the supporting-frame C at the point 11 and provided with the hand'operated catch 0, by means of which locking engagement may be made with the notches pp at the edge of the segment-guide q, the position of the hand-lever E when the gate is closed being shown in Fig. 3 by the full lines and when the gate is opened by the broken lines. The lower end of the hand-lever E is connected with the outer end of the lever Z of the lazy-tongs movement by means of the links r and 3. To the under side of the lever Z is socured the stud t, upon which is placed the flanged roller to, moving back and forth in the slot '0 of the fixed guide F, which is secured to the platform B by means of the ears to w, the said guide being deflected at its outer end a: in order to provide for the proper closing movement of the gate and for proper engagement with the locking-catches G at the end of the car-body A.

In operating the gate the trainman of the car takes hold of the handle y of the lever E and actuates the catch 0 to release the said catch from its engaging notch p, and then moves the lever to a position in which the catch 0 will engage with the notch 10, as shown by the dotted lines in Fig. 3, and in this case the gate-sections h and 0 will be drawn back and folded, as shown in Fig. 6, and upon the reverse movement of the lever E the said sections will be opened out and thrown forward, so that the forwardedge z of the gate-section it will engage with the groove of the lockingcatches G at the'end of the car-body, the gate being securely locked in both its opened and closed positions by means of the catch 0 and the notches p p.

The construction and arrangement of the deflected guide F may be varied. Therefore I do not limit my claims to the specific form of construction shown in the drawings.

I claim as my invention- 1. In a car-gate, the combination of the folding gate-sections hinged to each other, with a lever and a connecting-link pivoted to the folding gate-sections at opposite sides of the hinge-joint between them and forming therewith a lazy-tongs movement,whereby the gatesections may be either opened out or folded, substantially as described.

2. In a car-gate, the combination of the fold- I ing gate-sections hinged to each other, with a lever and a connecting-link pivoted to the folding gate-sections at opposite sides of the hinge-joint between them and forming therewith a lazy-tongs movement, the deflected guide, and the connecting means between the deflected guide and the lever of the lazytongs movement, substantially as described.

3. In a car-gate, the combination of the folding gate-sections hinged to each other, with a lever and a connecting-link pivoted to the folding gate-sections at opposite sides of the hinge-joint between them and forming therewith a lazytongs movement, a deflected guide, connecting means between the deflected guide and the lever of the lazy-ton gs movement, and the hand-operated leverconnected with the lazy-ton gs lever, substantially as described.

' 4. In a car-gate, the combination of the folding gate-sections hinged to each other, with a lever and a connecting-link pivoted thereto at opposite sides of the hinge-joint between the gate-sections, and forming therewith a lazy-tongs movement, and a deflected guide, controlling the outer end of the lever, means for actuating the lever along the deflected NICHOLAS H.
