CAR COUPLING.

SPECIFICATION formingpart of Letters Patent No. 503,646, dated August 22, 1893.

I Application filed December 27, 1892. Serial No. 456,503. (No model.)

To all whom it may concern.-

Be it known that I, ASHER A. BROWER, a citizen of the United States of America, residing at Des Moines, in the county of Polk and State of Iowa,have invented a Car-Coupling, of which the following is a specification.

The object of my invention is to provide a simple, durable and automatic car coupling adapted to carry a reserve link; to provide means whereby the link may be retained in a pendent position when not in use and also adjusted and held extended forward at any desired angle and elevation by a person at the side of a car as required in coupling two cars when their draw heads are not in the same horizontal plane.

My invention consists in the construction and formation of the draw head whereby a link maybe secured therein by a hook and be capable of a movement from a vertical to a horizontal position.

My invention consists further in the construction, arrangement and combination with a draw head of means wherebya link may be placed at any desirable incline to engage coupling devices located at different heights relative to the track surface, and in certain other features in the construction, arrangement and combination of parts as hereinafter 0 more specifically set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of two of the couplings attached to cars and in a coupled 3 5 position one of said couplers being shown in vertical longitudinal section. Fig. 2 is a vertical transverse sectional view through the line a:-w of Fig. 1. Fig. 3 is a top view of the same with parts of the draw head broken away to show its interior construction. Fig.

4 is an enlarged perspective view of the link engaging hook. Fig. 5 is an enlarged perspective view of the device for elevating the link. Fig. 6 is a side elevation of two couplers attached to cars and in acoupled position one of said couplers being shown in longitudinal section to illustrate certain modifications of the device shown in Fig. 1. Fig.7 is

a perspective view of the coupler in its modified' form attached to a car, as required for practical use.

Referring to the accompanying drawings the reference letter A is used to designate the car, A a draw bar secured thereto in the ordinary manner and having its draw head formed as follows:

A designates a link cavity extending from the face of the draw head rearwardly and having its bottom surface inclined and rounded in such a manner as to direct a link into said cavity. In the rear of said inclined surface is a cavity A of such a size and shape as to allow the end of a link to be placed therein below the plane of said inclined surface. Portions of the bottom of 6 the draw head are also removed to produce parallel slots A A and a link support A adapted to allow a link when placed in the link cavity through the open front of the draw head to swing to a vertical position and have its top below the plane of the bottom of the link cavity: that is:the bottom portion of the draw head, A, extending from a point below the rear end of the link cavity consists of a straight piece of metal integral with the draw head and running longitudinally thereof in its central portion and having an upwardly inclined surface on its front face and a notch in the rear of said inclined surface, in which a link may be hung to swing from a horizontal to a vertical position, and be below the plane of the bottom of the link cavity when in a vertical position.

B designates a hook for engaging the link. This hook is fixed to a rock shaft B in the rear of the draw head to swing vertically a portion of the top of the draw head being re moved for this purpose. The pivotal point of the hook B is preferably at or below its draft center, so that a pull upon a link engaged thereby will not tend to .raise the hook.

B designates a rotatable shaft mounted in suitable bearings secured to the end of a car and B is a chain wound thereupon and secured to a lever B which lever is fixed to the 5 said rock shaft 13 to provide means for raising or lowering said hook from the side of the car.

B designatesa detachable covering placed on top of the draw head to allowafree movetoo ment of the hook B and protect the same from snow, ice, disc.

I have provided means for raising the links from a verticalposi tion to any desirable incline in order to couple with draw heads located at various distances from the ground surface, as follows:

O O designate two bent levers joined near their lower ends by the cross piece 0 and loosely mounted at their top end portions upon the endsof the rock shaft B in such a manner as to depend from the sides of the draw head and to have their lower ends adapted to enter the slots B in the bottom of the draw head when raised.

the top surface of one of the levers near its point of attachment with the rock shaft'B and O design-ates a chain fixed to said hook and wound upon the rotatable shaft 13 in'an opposite direction fro-m the chain B so that when one is wound up. the other is loosen-ed. Thus it will be seen that a rotation of the shaft B in one direction will raise the hook B and when rotated in an opposite direc a tion will raise the outer end of a link in the coupler. In the modification shown in Figs. 6 and 7 i the chain B is shown to be extended through i an opening in the top of the detachable cover B andattached direct to the hook B which in this instance is not pivoted to any support but has its rear end rounded and placed in'a rounded cavity in the draw'head and h'as'its front face inclined downwardly and forwardly to engagea mating portion of the draw head, so that-a forward pull upon the hook will prevent the same from being raised and the curved lovers, 0, C, have their upper ends ex.- tended upwardly and forwardlyand are united above the draw head and have the chain 0 connected therewith and said chain, 0 isv wound upon a drum D to move the levers G O a greater distance upon each revolution of the shaft B Having thus described theconstruction, op?

eration, and function of each part of the-coup V ler,-what I claim as my invention, and desire to i secure by Letters Patent of the United States i therefor, is- A,

1. In a car coupling a draw-headha-ving a link cavity, a notch in the rear of the link i cavity toadmit the end of the linkand slots in the bottomof the draw head to allow a link having its end in the aforesaid notch to swing to a vertical position and nieanslfor elevating the outer end of said link.

2. In a car coupling a draw head having a link cavity a notch in the rear of the link cavity adapted to admit the end of the link and allow it to pass below the bottom of the link cavity for the purposes stated slots in the bottom of the draw head to allow a link when placed in the said notch to swing to a vertical position and means for elevating the outer end 7 of said link.

3. In acar coupling the combination of the following elements, to wit: a draw head having a link cavity adapted to admit a link and allow it to swing from a horizontal to a vertical position, two bent levers pivoted to the op- C designates a hook formed on or fixed to posite sides of the car and h'avingthe'ir lower ends adapted to engage the link and means for manually operating the said levers from the side of a car to elevate the outer end of the link for the purposes stated.

4;. In a car coupling the comb'na ""on of the followingelements, to wit: a draw bar connected with a car in the ordinary-manner a draw head formed thereon and provided with a link cavity, a. notch formed in the rear end of, the link cavity as set forth, slots for-med I in the sides of the bottom of the draw head for the purposes stated, a hook fixed to a rock shaft in the rear end of the draw head and adapted to engage the bottom of the link cavity inadvance of said notch, two bent leversloosely mounted upon asuitab'lesupport at the sides of the draw head and adapted to be brought into engagement with the said link, to elevateits outer end, a rotatable shaft mounted in suitable bearings attached to the end of the car to be manually operated,-a chain attached to said shaft and to the rock shaft to which the said hook is fixed and a chain wound upon the said shat-tin an opposite direction from the aforesaid one and attached to the bent levers substantially in the manner set forth for the purposes stated.
