COUPLING STIRRUP AND CENTERING DEVICE FOR RAILWAY"GAIRS- SPECIFICATION forming part of Lett r P81176711; 17 755,622, dated March 29, 190%..

Application filed June 22, 1903. serial No. 162,477. (No model.) i

To all whom it may concern:

Be it known that I, WILBUR G. CORY, a citizen of the United States, residing in New Haven, in the county of New Haven and State of Connecticut,have invented a new and useful Improvementin Coupler Stirrups and CenteringDevices for Railway-Cars,of which the folaround curves and which will also hold the coupler normally in its proper central position in respect to the car.

My invention consists in the means I employ to practically accomplish this object or result-th at is to say, it consists in a stirrup or carry-lron having a guide-channel, preferably U shape in cross-section, to receive and guide a coupler-centering device and a spring and followers therefor and provided with shoulders or stops for the followers to abut against, in connection or combination with a coupler-centering device having a seat on its upper side to receivethe coupler drawbar and end flanges to embrace and bear against the followers, a spring and a pair of followers for causing the coupler-centering device to return to its normal or central position, while permitting the coupler to swing laterally from side to side, as required. The followers are interposed between the stirrup or carry-iron and the coupler-centering device, the followers resting on the stirrup or carryiron and the centering device being above the followers. The centering device is also pro vided with guides or flanges at its side edges, engaging the upper edges of the webs which form the channel or guide grooves in the carry-iron or stirrup for the-centering device.

The carry-iron and the stirrup or centering device are both able iron.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a central vertical longitudinal section taken on line 1 1 of Fig. 2 and showing a passenger-car coupler provided with my invention. Fig. 2 is a front end view, partly in vertical section, on line 2 2 of Fig. 1. Fig. 3 is a plan view of my improved coupler stirrup or carry-iron and centering device. Fig. 4 is a section on line i 4 of Fig. 3. Fig. 5 is a detail perspective View of one of the followers, and Fig. 6 is a detail perspective View of the coupler-centering device.

In the drawings, .A represents a portion of a car-frame; A, the coupler; A the drawbar; A the draft-rigging spring; A*, the buffer, and A the buffer-spring, these parts hepreferably cast and of malleing of any ordinary or customary construction.

B is my improved coupler stirrup or carryiron, the same being preferably of malleable iron and having horizontal webs b for attachment to the car and depending webs or fllanges 6 6 to give room for the coupler draw-bar, and provided with an integral guide trough or channel B to receive. the coupler-centering device and permit it to reciprocate laterally of the car. The guide trough or channel B of the centering device is open at the top and preferably U shape in cross section and is formed by the curved side wallsor web's b of the carry-iron or stirrup. The carry-iron or stirrup is also provided with shoulders or stops 1) for the followers 0 C of the centering device D to abut against. The centering device Dis preferably also of malleable iron and has upright flanges d d, forming a seat D between them for the draw-bar of the coupler, and depending flanges or ends at 0?, fitting within the guide trough .or channel B of the carry-iron to embrace and bear against the. followers C 0.

channel or chamber formed therein to receive per ends or edges 0 to fit the under face of the bed 111 of the centering device. The followers C also have bosses or thimbles c to fit in the ends of the spring F.

In operation when the coupler swings to 7 either side the centering device D moves with it, thus compressing the spring F, one of the followers C being held stationary by engagement with the corresponding stopor shoulder 6 on the carrydron, while the other follower moves with the centering device. The compressedspring will thus return the centering device and coupler to their central. position as soon as the train again passes onto straight track, and the spring of the centering device will also normally hold the coupler in its central or proper position longitudinally of the car. i I As in my invention the stirrup or carryiron is itself provided with achannel or chamber longitudinally thereof to receive and guide the centering device and with stops or shoulders for the followers, in which channel or chamber the spring and followers are contained, and as the centering device itself covers this channel or chamber on the top and incloses and embraces at its ends the followers and spring the spring and followers are en-' tirely inclosed and the whole device is at once composed of few partsand made of simple, strong, efficient, and durable construction, not liable to wear, break, or get out of repair, while at the same time operating most 'efiieiently.

The upright flanges d d are provided with curved inner faces d to better permit the centering device D to reciprocate longitudinally of the carry-iron B without cramping as the coupler and draw-bar swing laterally from side to side.

I claim 1. A car-coupler supporting and centering device, comprising in combination a stirrup or carry-iron having an internal guide-trough a centering device, spring and followers, and provided with shoulders or steps for the followe s to abut against, of a centering device having upright flanges forming a seat for the coupler draw bar, and depending ends or flanges fitting within said guide trough or channel of the stirrup or carry-iron, and em.- bracing the followers, a spring and a pair of followers inclosed and embraced between said stirrup or carry-iron and said centering device, substantially as specified.

2. The combination with a car-coupler stirrup or carry-iron having a channel or chamber open at the top to receive a spring and a pair of followers, and provided with stops or shoulders for the followers to abut against, of

a coupler-centering device having a seat for the draw-bar of the coupler, and provided with depending ends or flanges fitting within said channel or chamber of the stirrup or carry-iron to embrace and bear against the followers, substantially as specified.

3. The combination with a coupler-stirrup or carry-iron, having a channel or chamber to receive a spring, and shoulders or steps for the followers of the spring to abut z'igainst, of a couplercentering device having a seat for the draw-bar of. the coupler and ends fitting within said channel or chamber of the stirrup or carry iron and embracing and bearing against the followers, and guides or flanges fitting the upper edges or faces of the webs or walls of the channel or chamber in the stirrup or carryriron, and a spring and foliowers,

substantially as specified.

i. A malleable-iron car-coupler stirrup or carry-iron, having horizontal webs or flanges 5 b for attachment to the car, and depending carry-iron, having horizontal webs or fla'nges y b '6 for attachment to the car, and depending webs or flanges b b and Z2 6 forming a space for the draw-bar between them and providedwith a channel or chamber B formed by curved walls 6 b and furnished with shoulders or stops 6 substantially as specified.

7 A car-coupler-centering device B, having upright flanges dd forming a seat for the draw-bar of the coupler, and depending ends or flanges d d to embrace and bear against the followers in combination with a carryiron having an integral guide trough or channel within which said depending'ends orflanges d d fit, substantially as specified.

8. A car-coupler-centering device D, having upright flanges 01 (Z forming a seat for the draw-bar of the coupler, and depending ends 0.1" flanges d d to embrace and bear; against the followers, and ribs or websa d uniting said flanges d d in combination with a carryiron having an integral guide trough or chanme! within which said depending ends or flanges d d fit, substantially as specified.-

9. A car-coupler-centering device D, having upright flanges d d forming a seat for the draw-bar of the coupler, and depending ends or flanges Li d to embrace and bear against I the foilowers, ribs or Webs (Z d uniting said flanges (Z (Z, and a horizontal bed d provided with guides or flanges d, d, at its edges, substantially as specified.
