Specification of Letters Patent.

Patented Jan. 1%, 1916.

To all whom it may concern Be it known that I, Gaoaos W. SCHNEIDER, a citizen of the United States, residing at Argenta, in the county of Pulaski and State of Arkansas, have invented a new and useful Draft-Gear, of which the following is a specification.

The device formin the subject matter of this application is adapted to be assembled with a draft rigging of known form, to constitute a support therefor, the structure being of peculiar utility upon railway vehicles.

The invention aims to provide novel means for supportin the draft beam and the coupler so that t ese parts will be permitted to have the necessary movements, accidental misplacements thereof being prevented.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention ap ertains.

With the above an other objects in view which will appear as the description roceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings :Figure 1 shows in longitudinal section, one form of draft rigging wherewith the device forming the subject matter of this application has been assembled, parts bein broken away; Fi 2 is a side elevation s owing a portion ot the structure delineated in Fig. 1, parts being in section; Fig. 3 is a vertical transverse section wherein sundry parts of the draft rigging appear in elevation; Fig. 4 is a cross section taken approximately on the line H of Fig. 1; Fig. 5 is a to plan of the supporting arm; Fig. 6 is a side elevation o the supporting arm; Fig. 7 is a fra mental cross section showing a slight modification in the invention.

T he device forming the subject matter of this application is adapted to be em loyed in connection with a known form 0 draft rig ing, and this rigging will first be descri ed, proper indication being made at the point where the description of parts considered to be new begins.

The numeral 1 designates the floor of a railway vehicle, the numeral 2 designating longitudinal sills.

lhe numeral 3 indicates an end sill, the numeral 4: designates a transverse buli'er beam, and the numeral 5 denotes a butler block on the bufier beam.

A draft beam 6 is shown, the same having a vertical opening 7.

Secured in a manner to be described hereinafter to the forward end of the draft beam 6 is a coupler 8.

For the parts above described and enumerated no novelty is claimed, saving in so far as they may cooperate with elements to be described hereinafter.

In carrying out the present invention there is provided an arm 9 located beneath the draft beam 6 and the coupler 8. Bolts 10 or other securing elements are employed for uniting the coupler 8 with the draft beam 6, and in the present embodiment of the invention, the bolts 10 are elongated sufiiciently so as to pass through 0 enings 11 in the arm 9, thereby to hold tie arm in place, as shown best in Fig. 1. At its forward end, the arm 9 is provided with a table 12 which bears against the under face of the coupler 8, intermediate the ends of the coupler, the table 12 having at its sides, upright flanges 14 which lie upon opposite sides of the coupler, as shown in Fig. 3. The arm 9 embodies longitudinal side flanges 15 which. at their rear ends, may coact with the side faces of the draft beam 6, one of the flanges 15 preferably being cut away at its rear end, as indicated at 16 in Fig. 5, in order to accommodate certain enlargements sometimes found upon the draft beam 6. Intermediate its ends the arm 9 is supplied with a transverse rib 17, which, as shown in Fig. 1, engages the forward end of the draft beam 6 and aids in holding the arm 9 in place. Adjacent its rear end, the arm 9 is provided with spaced projections 18 which bear a ainst the draft cum 6 at opposite sides oi the opening 7 therein. In the arm 9 between the projections 18, there is formed an elongated opening 19 lying below the opening 7 in the draft beam 6. About the openin 19 in the arm 9, and upon the under sur ace of the arm, a concaved seat may be formed. The flanges 14 of the arm are provided with eyes 21, receiving the lower ends of upwardly extended chains .22, assembled with eye bolts .23 mounted in the butter beam 4.

The invention com arises an upright support in the form oi a rod 2-1:, extended through the opening T in the draft beam 6, and through the opening 19 in the arm 9. The support 24 is provided adjacent its lower end with an opening :25 through which may be straddled a key 526 upholding an abutment 27, engaging the lower end of a helical compression spring .28, the upper end of which is engaged by an abutment 29 having a rounded end 30 received in the concaved seat 20 of the arm. Pivotally mounted in an eye -12 formed at the upper end of the rod or support 24: is a link 3]., concatenated with a rectangularly disposed link 32, the upper end of which is enlarged to receive a transverse pin 33, concavcd downwardlv intermediate its ends as shown at 34 in bi 4. Upon the loiwitudinal sills S2, U-shapc brackets are placed, the same being secured by means of attaching elements 36. The brackets 35 are provided, as shown in Figs. 2 and l with ownwardly concaved seats 37 in which the ends of the pin 33 are received. When the car is of steel construction, the sills 2 may be replaced by channels 38 as shown in F1". 7, and under such circumstances, the brac -ets may be of hook-shape, the upper arms thereo being united by means oi attaching elements it) with the upper flange of the channel 38. The seat 41 is of the sort hereinbefore described and indicated at 37.

The arm 9, being attached to the draft beam 6 by means of the bolts 10, serves to uphold the beam and maintain it in line with the coupler 8 as Fi s. l and 3 will clearly show. The spring 28 a sorbs the shock reduced by a downward movement of the lieam 6 and the coupler 8 during the coupling 0 eration, and serves to raise these parts to t \eir normal positions. The spring 28, further, permits the beam 6 and coupler 8 to have the necessary vertical movement while the vehicle of which the draft rigging constitutes a part is running on the road. If it is desired to vary the compressive effort of the spring 28, washers (not shown) may be inserted between the abutment 27-and the key 26, as a person skilled in the art will understand readilv. Owing to the presence of the links 31 an 32, the draft rigging may be iermitted to have the necessary reciprocat- In; movement in a longitudinal direction. Wien the draft rigging moves longitudinally as above described, the ends of the pin 33 are adapted to ride back and forth in the seats 37, and because these seats are down wardly concaved, the pin 33 will be returned to a centralized position. Further, the link 4.2 will'be centralized on the pin 33, because the pin is downwardly concaved as shown at 34 in Fig. -l. The chains .21 act as safety devices supporting the draft mechanism should the rod 24 or any parts assembled therewith give way. The rib IT and the proections 18 on the arm 9 coact with the draft cum 6 to sustain the arms against longitudinal strains as hereinbeforo pointed out, and as evident from Fig. 1.
