RAILVIAY-BRAKE APPLIANCE.
Specification of Letters Patent.
Patented Jan. 13, 1920.
Application filed October 30, 1918 Serial No. 260,356.
To all whom it may concern:
Be it known that 1, JAMES F. DRlNK- WATER, a citizen of the United States, residing at lVillard, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in RailwayBrake Appliances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in railway brake appliances.
An important object of this invention is to provide an apparatus of the character described adapted for attachment to cars for use in place of the usual chain structure connecting the brake mechanism withthe operating means therefor.
A further object of this invention is to provide an eflicient manually operated brake operating structure adapted for use in conjunction with an air brake system. I
A further object of the invention is to provide an apparatus of the character described, which is of highly simplified construction, reliablein use. and easy to install on standard rolling stock.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,-
Figure 1 is a side elevation of an apparatus embodied in my invention,
Fig. 2 is a vertical longitudinal section through the same,
Fig. 3 is a horizontal section taken on line 3-3 of Fig. 1, F Fig. 4 is a section taken on line -ill of ig. 1, F Fig. 5 is a section taken on line 5-5 of Fig. 6 is a section taken on line 66 of Fig. 3, and
Fig. 7 is a vertical section taken on line 77 of Fig. 3. r
In the drawing, wherein for the purpose of illustration is shown the preferred em bodiment of my invention, the numeral 10 generically designates an apparatus embodied in my invention. The same comprises a rectangular base 11 having longitudinally extending side walls 12 and vertically disposed end walls 13 secured to the base 11 by bolts 14. A vertically disposed brake stafi" 15 has its lower end journaled in a bearing 16 carried by the rear portion of the base 11. As shown in Fig. 3, the brake staff 15 has a worm 17 arranged thereon and meshing with a worm gear 18 carried by a horizontally disposed shaft 19. A set screw 20 provides a rigid connection between the worm gear 18 and the horizontally disposed shaft 19. The shaft 19 extends longitudinally of the base 11 and has its ends journaled in bearings 21 carried by the vertical end walls 13. As clearly shown in Fig. 2, the forward end of the base 11 extends beyond the forward end wall 13 and forms a longitudinally extending. guideway 23. The guideway 23 includes side walls 24 and a base 26. A rack bar 27 having teeth 28 is received in the guiding member 23 and is adapted to partake of a reciprocatory movement therein.
As clearly shown in the several figures, the rack bar 27 is adapted to mesh with a relatively large worm gear 29 carried by the horizontally disposed shaft 19 at its forward end portion. As shown in Fig. 6, the forward end portion of the shaft 19 extends into a. centrally disposed-longitudinally extending rectangular opening 30 in the worm gear 29, and is held therein by a set screw 31. It will be apparent that the rotation of the brake staff 15 causes the horizontal shaft 19 to partake of a like movement and thus actuate the rack bar 27. As clearly shown in Fig. 2, a loop 32 is arranged parallel to the rack 27 and is provided at one end thereof with an eyelet 33 for connecting the loop 32 with the braking mechanism of the car. The loop 32 is provided with a longitudinally extending opening 34 receiving an L-shaped arm 35 carried by the rear end of the rack bar 27. Upon the rearward movement of the rack bar 27 the L-shaped arm 35 will engage the rear end of the loop 32 and draw the same rearwardly. The rearward movement of the loop 32 causes the actuating of the braking mechanism, which upon return of the loop, is automatically returned to a non-operative position by a spring mechanism as is usual in brake structures. In the use of my invention, it will be apparent that the usual air brake system may be applied to the braking mechanism and be operated in conjunction with the apparatus above described. The applying of the brakes by air pressure will cause the loop 32 to move rearwardly independently of the rack bar '27.
With reference to the foregoing, it will be apparent that I have provided a highly efficient and reliable brake operating structure adapted for attachment to cars without in any Way interfering With the operation of the air brake system. 7
lVhile I have shown and described the preferred embodiment of my invention it is understood that I may make such minor changes in arrangement and construction of parts as will remain Within the spirit of the invention and the scope of the appended claims.
Having thus describedmy invention, what I claim is 1. An apparatus of the character described comprising a base; a horizontally disposed shaft carried thereby; a gear carried by said shaft; a brake staff having one end thereof jonrnaled in said base; a gear car-- ried by said stafi and meshing with the gear carried by said shaft; a rack bar slidably carried by said base; a worm gear carried by said shaftand meshing with said rack bar; an elongated loop arranged parallel with the rack bar and having connection with a brake mechanism; and an arm extending from said rack bar and having a sliding connection with said loop, said rack bar being adapted to be operated by the rotation of said brake staff.
2. An apparatus of the character described comprising, a base; a horizontally disposed shaft carried thereby; operatingmeans for said shaft; a worm gear carried by said shaft; a rack bar slidably carried by said base and meshing with said worm gear; an elongated loop arranged parallel to said rack bar; and an L-shaped arm slidably con nected ith-(said elongated loop and ex- I tendingfrom said rack bar, said elongated loop being adapted to be operated by the operation of said rack bar.
3. An. apparatus of the character described a base; a horizontally disposed shaft carried thereby; gear carried by said shaft; a vertically disposed brake staff having one end thereof journaled in said base; a worm gear carried by said staff and meshing with the gear carried by said s iaft; a rack bar carried by said base; a Worm gear carried by said horizontally disposed shaft and meshing with, said rack bar; and
comprisin an elongated loop having sliding connection and being adapted to be operated by the actuation of said rack bar.
5; An apparatus of the character described comprising a base; a horizontally disposed shaft carried thereby; a worm gear carrled by said shaft; a longitudinally extending guideway carried by said base; a rack bar slidably arranged in said guideway and meshing with said Worm gear; operating means for said shaft; an elongated loop arranged parallel to said rack bar; and an L- shaped arm extending from said rack bar and having sliding connection with said elongated loop said elongated loop being adapted to be operated by the actuation of said rack bar.
