DOOR-LOCKING DEVICE FOR CANE CABS.

Application filed June 29,

7 Reference is had to the accompanying drawings which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claimswil occur to persons skilled in the art.

In said drawings:

Fig. 1 is a partial side View of a cane car with my invention applied thereto,a portion of the car being broken away;

Fig. 2 is a similar view of one of the door locks shown in Fig. 1, but on a much larger scale' 3 is a side view of the locking mechanism, as seen from the right of Fig. 2, with certain associated parts in cross-section;

' Fig. 4: is a plan view of the door locking mechanism, with parts partly broken away and in section; I

Fig. 5 shows a mid-section through the locking mechanism taken as indicated by the line 5-5 in Fig. 1, showing the door released and swung part-way open My invention relates to door locks, suitable for railway car doorsand the like, and especially useful for doors of general utility cars, cane cars, etc. I aim to provide'a simple, convenient, elfective locking mechanism; easy and inexpensive to manufactureand install; secure in action; convenient and quick in operation. L

Fig. 1 shows acane car of usual type, with side doors 9, 10 of open-work construction. The door 9 comprises a series of upright I bars 11 having their upper ends hinged or pivoted at 12 to a longitudinal top rail 13 and secured at their lower ends to a longitudinal lower rail 14 of Z-bar section. The bottom rail 14 is arranged with one flange 15 turned downward (Figs. 2 and 3), and the other flange turned upward. Near their upper ends, the uprights 11" are secured to a longitudinal channel bar 16, and the door as a whole is braced by a diagonal channel bar 17, also secured to the uprights.

For holding the door9 shut,there is provided a baror shaft extending along adjacent the lower door edge 15 and shiftable 1926. Serial No. 119,495.

disk somewhat resembling a steam engine eccentric. Instead, however, of being sup ported or carried bythe shaft 20 and actuating other parts through astrap', as in'a steam engine, the eccentric 25 is in the present instance supported by a bracket or housing structure'26 (riveted to the sill 22 at 27) that engages the eccentric periphery like a strap and the shaft -20 is eccentrically mounted in and shifted by the eccentric. For this latter purpose, the eccentric 25 has a notch or recess 28 extending inward from its periphery at one side. As here shown, the shaft '20 is of rectangular (square) cross-section, and the recess 28 oflike formpthough affording some clearance around the shaft. L The inner corners of the recess 28 are undercut in a bead or fillet at 29, (Fig. to afford clearance and obviate any possible sticking or binding on the'shaft 20, as well as to facilitate machining. As shown in F igs. 4 and 5, the eccentric 25 has a' deep circumferential groove 30 in its periphery, extending all the way around it except forran interval at the recess 28. At the base of the bracket mounting 26 adjacent the car sill'22, there isavertical opening or holefor a key 31 to engage in the groove 30 and hold the eccentric 25 in the bracket against displacement lengthwise of the shaft 20. As here shown, this key 31 has the form of a roundretaining pin witha head at its upper end, and is securedin place by means of a cotter pin key 32 through a transverse hole in its lower end, below the bracket 26. As will be apparent from comparison of Figs. 3 and 5, the'key 31fnot only prevents withdrawal ofthe eccentric 25 from' the mounting or housing 26, but also serves as 'a stop for limiting rotation of the eccentric to about 180 degrees. The bar or shaft 20 extends loosely throughthe eccentric 2 5, and

rides against the strap of the bracket 26 when below the axis of the eccentric.

Whenthe shaft20 in the eccentricnotch '28 is in its uppermost position, as shownin Fig. 7

3, said shaft extends along in front of the flange at the lower edge of the door 9 and holds it against the sill 22, thus securely looking the door against opening. When, on the other hand, the. shaft is-in its lowermost position, as shown in Fig.5, then the'shaft is well below the lower door edge 15, with ample clearance for the door to. swingopen above it, as shown inFiggo."

Vhilewa'rious arrangements migh't be employed for operating the eccentric to shift the shaft 20, a very simpl'e'one is to do so by rotation of the shaftrQO itself, as here shown. For this purpose, one end 33 of the shaft F20; may: be. bent at right angles (Fig.1)

to serve as, a crankqfon-turning the shaft. This crank33 may conveniently,- be secured in u-pright (doorelockin-g position by means of a:;I'lI1g OIrllI1ki3ff' OD a =slide-35 mounted on the end post 36 of 1 the superstructure of the car The cranld33can readily be-released for; operation by inerelylifting; the link .34 over the; upper; end -of; the; crank and letting thiisili-nkfallto one-side; To unlock thegdoor,

it'is thenonlynecessary to allow the crank 33 to swing outward and downward, thus turning the shaft 29-. :and the eccentric 25-- and shifting-therod-QO from itsposition in Fig.

To re-secure-the door, theoperation is reversed; 'Aseshown ln' Fig 1, thedoor 10 and its locking mechanism are similarlyv constructed and-arranged, except that the .door 10 extends lo-wer and itsshaftiQO, and shiftingdevices 12L? are mounted ii/{3. lower position on below. the parts-20,-,2l romhe door-9 to the .samea-en'd-posty36 from which thewdoor 9 is -controlled.- To obviate any, trouble from sagging-ofthelongyshaft 20? under its own weight; one of {the-devices 121 may be providednearthe-end post 36 soasvto support, raise, and lower this: -whole end of the shaftin 1 unison with the portion that actually en- ,gages 'andlocks the door;l0.; I
