.ARGYLE CAMPBELL, OF CHICAGO, ILLINOIS, ASSIGNOB, TO ENTERPRISE RAILWAY EQUIPMENT COMPANY, OE CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
HOPPER-GAR-DOOR-OPERATING MECHANISM.
Specification of Letters Patent Be it known that I, ARGYLE OAM BEIL, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement' in Hopper-Car-Door-Operating Mechanism, of which the following is a specification.
This invention relates to improvements in hopper car door-operating mechanisms, and more particularly to the type of'door operating mechanism shown and described in my 737,784, for hopper cars, filed December 20, 1912.
An object of the invention is to provide simple means for adjusting the lengthof the chains of the door operating mechanism.
Another and 'more specific object of the invention is to provide a sheave wheel hfLV-r ing means for independently and adjustably attaching two chain ends thereto.
The invention furthermore consists in the improvements in the parts and devices and. in the novel combinations of parts and devices herein shown, described or claimed.-
Inthe drawing forming a part of this specification, Figure 1 is a detail, longitudinal, sectional view of a portion of a hopper car showing one construction embodying my improvements, the section being taken substantiallycentrally of the car. Fig. 2 is a transverse, detail, sectional view of a por tion of a hopper car embodying my improvements, the section being taken on a line to the left of the structure shown in Fig. 1, and Fig. 3 is a detail sectional view of the improved, sheave wheel.
In said drawing, the center sills of the car are denoted by the references 10, and mounted betweensaid center sills on supporting brackets 11 is a short shaft I2, the
- latter being provided with a drum 13 havco-pending application, Serial No;
the chain. The chain 18 has each of its ends adjustably secured to another sheave wheel 24 and 25 being arranged at right angles to each other for a purpose hereinafter de scribed. The slots 24 are each adapted to receive the eyes 26 of the eye-bolts 27, connected to each end of the chain, and as will be obvious, the slots 24 will prevent the eye.- bolt from rotating, but will allow the latter to be adjusted up and down by means of the nuts 28, which engage the eye-bolts beneath a ledge or bracket 29 formed in'the sheave wheel; The other slots 25 are each adapted to receive the end'links of the chain ends and will also serve to prevent the chain fnbm twisting, at the same time permitting the end links to be adjusted in and out of the slots. ing plate 30 to' prevent the nut from rotating.
From the foregoing description, it will be seen that although the chain 1.8 is secured to the sheave wheel 17 by fixed means, yet
the length of each portion of the chain is independently adjustable by means of the construction of the sheave wheel 27 and eyebolts at the ends of the chains, whereby any wear or give of the parts may be compensated for to insure the proper closing of j Patented May 20, 1913. Application filed January 30, 1913. Serial no. 745,057.
' extending slots 24 and 25, said pairs of slots Each nut 28 is provided with a lockthe hopper doors 16. At the same time, the 7 adjustable attaching means for the "ends of the chain is prevented from rotating o r twisting, which would otherwise occur to thereby increase the length of'the chain.
Although I have herein" shown and described what I now consider thepreferred embodiment of-my improvements, yet it will be understood that the same may be changed as to the details of construction, without departing from the spirit of the invention, and all changes are contemplated as fall within the scope of the claims appended hereto.
I claim 1. A door operating mechanism of the 7 character described including, a chain, a
sheave Wheel over which said chain winds and to which one end of the chain is secured, and means for adj ustably securing said end of the chain to the sheave wheel, said means including an eye-bolt, a recess in the sheave wheel through which ,the' bolt passes, said recess having a slotted portion in which the eye of the eye-bolt is slidable but is prevented from turning, substantially as specified.
2. A door operating mechanism of the character described including, a sheave wheel, said sheave whee-l being provided with a pair of recesses, each recess being provided with a slotted portion, and two chain ends adjustably secured to said sheave wheel by means including an eye-bolt, the eye of which is adjustable up and down said slotted portion, but is prevented from twisting therein, substantially as specified.
3. A door operating mechanism of the character described, including a chain, a-
sheave wheel over which said chain winds and to which one end of the chain 1s secured, and means for'adjustably securing said end of the chain to the sheave wheel,
character described, including a chain, a-
sheave wheel, and two sets of devices for independently and adjustably attaching the two ends of said chain to the sheave wheel, each set of devices including an eye-bolt secured to the end link of the chain, a recess in the sheave wheel through which the eye bolt is adapted to pass, said recess having slotted portions arranged at right angles to each other, one of the slotted portions being adapted to receive the eye of the eye-bolt and the other being adapted to receive the end link of the chain, substantially as specified. a
5. A door operating mechanism of the character described including a sheave wheel, a chain, and devices for independently adjustably connecting each end of said chain to the sheave wheel, saiddevices including an eye-bolt, and means integral with the sheave wheel for preventing the eye-bolt from turning, substantially as specified.
