JOHN EDMAN, .OF'MINNEYAPOLIS, MINNESOTA, nssrenon To EDMAN' CAR noon QQMPANY, or MINNEAPOLIS, mmNEsorA, conron'nrron or mmnnso'ra.

' cnnflnooa LocK;

'Be it known that I, JOHN neapolis, in the county of Hennepin and State of Minnesota, have invented certainnew and useful Improvements in Car-Door Locks; and Ido hereby declare the follow-j ing to be a full, clear, and exact description of'the invention, such as. will enable others skilled in the art to whichit appertains to make and use'the same. Y 7 f My invention has for. its object to provide means for car doors, such as used on re- 1 the door frame and are generallyfdesignated' as flushdoors.

' scribed'and'v defined in the claims.

In the accompanying drawings which frigerator'cars, and which. doors are adapted to be pressed laterallyinto their seats in To. the above ends, generally statedythe invention consists of thefnovel devices and combinations .of device's herelnafter deillustrate the invention like'characters indicate like parts throughout the several views.

Referring to the drawings:

- 1 Figure l is aside elevation showing the central portion of a car body .andits door,

and my improved door lockingjandclamping means applied thereto; Fig. 2 is a vertical section on theline 2+2 of Fig.1,

Fig. 8 's av vertical 'sectionbn the] line 3 -,3 of Fig. l; and

Fig.4c.,is a vertical section 101;. the line H ofFig. 11, some partsbeing removed. The car body is indicated by theinumeral 5 and its door, which is of. the laterally movable flush door type, by the, numeral 6.

This door maybe supported or hung by any 'suitable .orjwell known means, not shown. It has beenfound difiicultby a person on the ground to tightly. force doors of this type into their seats; Hence, I combine with my improved locking means, a" n V levers/7. These levers 7,.at their upper en s, are PIV- pair of laterally crossed clampin oted to the ends of anchor bolts 8 that are extended through the side of the car ad-' 'jacent to the door'opening and preferably" above the center thereof, and are swiveled' so' that the said levers may be moved vertically by swinging movements on the axis may be held corners of. the door.

this way, the door can betigvh its seat in the car body.

I atented June 22, 1920. Application filed September 4,1919, seriai' ro. 321,623. r

of the anchor. bolts 8 'as well as laterally i on the axis of the pivotal connection between said'levers and anchor bolts.

At their inner ends, the hanger bolts 8 are shown as provided with nuts 9, but they in position by any suitable means.

The: two levers 7. are crossed approx}.

mately at their central portion, and the one is laterally bent at 7 so as to clear the other.. At: their lower ends, the said levers are adapted to be engaged with. laterally. oflset ends of anchor brackets 10rigidly se-v cured to the carbod just below ,the lower he levers 7, near their lower free ends, are provided with clamping bolts 11 having screw-threaded engagement therewith and provided with heads that'bear directly against metallic wearing plates 12 seated in and secured to the outer surface of the door near the bottom thereof. These clamping bolts 11 are provided with laterally bent outer ends bgmeans of which they ma be readil turne V I W hen the evers are engaged with the anchor brackets, as shown in the drawings, the. clamping boltsll may be tightened and thereby force the lower portion of the door tightly into its seat. As near as practicable to the. anchor bolts 8, the door 6, at its edges, is provided with small metallic bearing plates 13. with which the upper ends of the levers? engage to tightly force theupper portion of the door into its seat. In

tly forced into arelreleas'ed, they are adapted to be dro ped down into vertical positions indi ate by dotted lines in Fig. 1. 1 I The doorlocking thelevers 7 comprises a lower lock bracket 14 and an upperlock bracket 15... The lock,

bracket 15, at its lower portion, is v bolted,

riveted, or otherwise rigidly secured to the car door. The upper portion of. said lock bracket '14 is ofisetfrom the outer face of the door, so that it will also overlap. the

crossed portions of the lever 7 when turned downward. It should be noted that the pivoted bracket 15 has a rounded shoulder 15 which permits the said bracket to be turned hen the levers 'from an inoperativev upturned position through which an ordinary car seal 21 is adapted to be passedto hold said lock pin shown by dotted; lines inFig. 1, into the downturned operative position shown by full lines in Fig. 1,and conversely.

The two

lock brackets

14 and 15, at their adjacent edges, are provided with perforatedoiiset ears l7 and '18, respectively,

through which a lock pin 19 is adapted to be passed, as shown in the drawings. a This lock pin l9, advisedly, is connected to the, pivot bolt 16 by a short chain 20. The lock bolt 19, at its lower end, has a perforation iii working position, and to seal the car door so that the latter without detection. j

The improved device above described therefore affords, first, efficient means for i clamping the door into working position,

second, an eificientlook, and third, an eflicient sealing device. g
