NILLIAM II. EMERICK, OF CHICAGO, ILLINOIS.
DRAFT-RIGGING FOR CARS.
SPECIFICATION forming part of Letters Patent No. 693,643, dated February 18, 1902.
Application filed May 24, 1901.
To whom it may concern:
Be it known that 1, WILLIAM H.EMERICK, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Draft- Rigging for Cars, of which the following is a specification.
This invention relates to draft-rigging for cars. I
The object of the invention is to provide a construction of draft-rigging for cars which is simple and efficient and wherein renewal of the coupling bar or arm in case of breakage may be effected easily and readily.
Other objects of the invention will appear more fully hereinafter.
The invention consists substantially in't'ne construction, combination, location, and arrangement of parts, alias will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.
Referring to the accompanying drawings, and to-the Various Views and reference-signs appearing thereon, Figure 1 is a top plan View of a draft-rigging constructed in accordance with the principles of my invention, parts being broken out and in section. Fig. 2 is a horizontal longitudinal section of the same on the line 2 2 of Fig. 3 looking in the direction of the arrows. Fig. 3 is a view in sideelevation. Fig. 4 is a view in vertical longitudinal section on the line 4 4, Fig. 1, looking in the direction of the arrows. Fig. 5 is a transverse section on the line 5 5 of Fig. 4 looking in the direction of the arrows. Fig. 6 is a view similar to Fig. 1, showing a slightly-modified arrangement of parts embraced within the spirit and scope of my invention. Fig. 7 is a View in vertical longitudinal section on the line 7 7 of Fig. 6.
In the practical operation of cars the coupler arm or bar by which one car is attached at its end to the next adjacent car is subjected to heavy usage by reason of the pull exerted thereon when the cars are coupled up and by reason of the impact thereon during the coupling operation. By reason of this heavy usage breakage of the coupler arm or barfrequentlyoccurs. Inpriorconstructions of draft-rigging for cars embodying means of attachment of the coupler-arm to the carfierial No. 61,678- (No model.)
body it has been necessary in making repairs or replacements of the coupler arm or bar to remove the draft-rigging from the supporting-sills. This consumes time and involves the taking apart and replacement of the parts of the draft-rigging, which is a practical objection the present invention is particularly designed to overcome, andin accordance with the principles of my invention I provide a construction of draft-rigging which is exceedingly simple and efficient and wherein the coupling arm or bar may be readily removed and replaced in case of breakage without the necessity of removing, taking apart, or replacing the draft-rigging.
In the drawings I have shown various constructions and arrangements of draft-rigging embodying the principles of my invention.
Referring to Fig. 1, reference-signs 8 and 9 designate the side sills constituting the framework upon which the draft-rigging is supported and to which the rigging is connected, said sills being bolted or otherwise connected to the car-body in the ordinary manner.
Reference- signs 10 and 11 designate counterpart castings respectively mounted upon the rigging-sills 8 9. Said castings are provided with flanges 12, arranged to receive the sills 8 9 therebetween to aiford efficient means for clamping or bolting said castings to said sills, said castings being mounted upon the opposed inner faces or sides of the sills 8 9, respectively. On the inner opposed faces of castings 1O 11 are formed cooperating guideways 13 14, each adapted to receive a leg 15 16 of a U-shaped belt or strap, which constitutes the draft-strap. The outer ends of the legs 15 16 are slotted to receive therethrough a key or pin 17. The sills 8 and 9 are also correspondingly slotted in alinement with each other and with the free ends of the legs 15 16, the ends of the key or pin 17 extending into the slots 18 19 in said sills, as clearly shown in Fig. 2.
Reference-sign 2O designates the coupler arm or bar, which may be of the usual or ordinary construction and having a transverse slot or opening therethrough, as shown in Figs. 2 and 4, to receive therethrough the pin or key 17. In this manner the coupler-arm may be detachably connected to the ends or legs 1516 of the draft yoke or strap. The
ICO
I have shown in Figs. 1, 2, 3, and 4 a simple arrangement of spring or spring-buffer comprising end plates 22 23, suitably connected together by rods 24 25, upon which said plates loosely slide. Upon each rodismounted the coiled springs 26 27. All the parts of the spring-buffer mentioned constitute a connected frame arranged to be received between the castings 1O 11 and held in place by the flanges 28, which flanges, if desired, may be made removable to afford access to said springs when desired. The plate 22 of the spring-buffer is arranged to take bearing against the web or connecting portion 21 of the draft-yoke, and the plate 23 of the buffer is arranged to take bearing against the inner end of the coupler arm or bar, as most clearly shown in Figs. 2 and 4.
From the foregoing description it will be seen that when a pull is exerted upon the coupler-arm the buffer-plate 23 will take bearing against the shoulders 30 of the castings 1O 11, which thereby constitute a stop for said bufier-plate, and the pull exerted upon the coupler-arm 20 is transmitted through the draft-yoke and is imposed upon the bufferplate 22, which being movable and loosely mounted upon the bolts 24 is drawn yieldingly toward the plate 23, thereby imposing a compression upon the springs 26 27. Similarly in case of an endwise impact upon the coupler-arm-as when two cars come together, for inst-aneethe buffer-plate 22 strikes against the shoulder 31 (see Fig. 1) of the castings 1O 11, and the endwise projection of coupler-arm 2O forces the buffer-plate 23 toward plate 22 and imposes a compressive tension upon the springs. In this manner the parts are relieved of shock or jar. If'desired, the ends of the key or pin 17 may be retained in place and said pin or key prevented from working out of place by means of keepers 32 33.
From the foregoing description it will be seen that in case of breakage of the coupler arm or bar the same may be removed and replaced without disturbing the other parts of the draft-rigging by merely removing the keeper or the keepers 32 33 and withdrawing the locking key or pin 17, and when the new coupler arm or bar is inserted the same may be quickly locked or secured to the draft-rigging by again inserting the locking pin or key'17 in place through the openings 18 19 in the sills 8 9 and the openings in the ends of the legs 15 16 of the draft-yoke and through a transverse opening in the coupling-arm.
The construction shown in Figs. 6 and 7 differs from that above described with reference to Figs. 1, 2, 3, 4, and 5 only in the arrangement of the buifer-springs. For instance, the construction and arrangement shown in Figs. 1 to 5 and above described is known in the art as a twin arrangement, and the construction shown in Figs. 6 and 7 is known in the art as the tandem arrangement, of springsthat is, in the one case the set of springs are arranged side by side, whereasin the construction shown in Figs. 6 and 7 said springs 40 41 and 42 43 are arranged one behind and in line with the other, each set of.
springs being held between relatively movable buffer-plates 44 45 46 47. In the construction shown in Figs. 6 and 7, however, two locking pins or keys 48 49 are employed, the pin 49' passing transversely through the sills 5O 51 and the ends 52 53 of the couplingyoke and also through the coupler-arm 20, and the other passing transversely through slots or openings in the sills 5O 51 and betweenthe two sets of buffer-springs, said key 48 forming a stop or shoulder for buffer-plate 46, and the rear connecting-web of the yoke-strap forming a bearing for the corresponding plate 44 of the other set of springs to effect a compression of the springs under the influence of a pull exerted upon the coupler-arm,.and said key 48 forming an abutment for plate 45 of the one set of springs, while the end of the coupling-arm 20 forms an abutment for the corresponding plate 47 of the other set of buffer-springs to effect the compression of said springs under the influence of animpact imposed longitudinally upon the coupler-arm. In other respects the construction in the two cases may be the same.
It is obvious that my invention is not to be limited or restricted to any particular construction or arrangement of buffer-springs, and other forms of buffer-springs may be employed in connection with my invention without departure from the spirit or scope thereof. It is also obvious that changes and variations in the details of construction and arrangement of parts would suggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention. I do' not desire, therefore, to be limited or restricted to the exact details shown and described; but,
Having now set forth the object and nature of my invention and constructions embodying the principles thereof, what I claim as new and useful, and desire to secure by Letters Patent, is
l. A draft rigging for cars comprising side sills, independent counterpart castings mounted upon the opposed sides or faces of said sills, said castings provided with shoulders and having cooperating longitudinallyextending seats or ways in the opposed faces thereof, follower-plates arranged to be rea draftyoke loosely seated between said castings and arranged to straddle said plates, a coupler-arm and a removable key for connect.-

4. A draft rigging for cars comprising side sills, independent counterpart castings mounted thereon and provided with longitudinally-extending seats or ways on the opposed faces thereof, said casting also provided with shoulders arranged to project into said seats or ways, a draft-yoke having its sides received in the seats or ways in said castings, a coupling-arm, a removable key for locking said arm to said yoke and sills, follower-plates extending transversely between said castings and having their ends received in said seats or ways and adapted to be engaged by said yoke when moved in one direction and by said coupling-arm when moved in the other direction, and a spring-buffer mounted in said castings and between said plates, said shoulders limiting the movement of said plates, as and for the purpose set forth.
In witness whereof I have hereunto set my hand, this 22d day of May, 1901, in the presence of the subscribingwitnesses.
