To all whomitmoy concern."

Be it known that I, ALBERT DOBSON, a subject of the King of Great Britain, and residing at 507 Notre Dame St., in the town of St. Lambert, in the Province of Quebec, in the Dominion of Canada, have invented a new and useful Combination Door Fastener, of which the following is the specification.-

The invention relates to a door fastening mechanism as described in the present specification and illustrated in the accompanying drawings'that form part of the same.

The invention consists essentially of the novel features of construction pointed out broadly and specifically in the claims for novelty following a description in detail of the referred form of the invention.

T e objects of the invention are to facilitate the opening and closing of doors particularly the doors of freight cars and warehouses; to avoid the destruction by workmen of such doors in their efforts to get into a car or storage chamber; to decrease the multiplicity of separate'parts used in the door fastening devices; to furnish a safety lock that will be difficult always to tamper with without detection; and generally to grovide a serviceable, durable and cflicient oor fastener and accompanying parts.

In the drawin Figure 1 is a side eleva:

tion of car wal, and door broken away,

showing the door fastening mechanism applied thereto. Figure 2 is a cross sectional view of the door and wall showing an end elevation of the fastening mechanism.

Figure 3 is a cross sectional view on the line 3-3 in Figure 1.

- Figure 4 is a perspective detail of the locking pin bracket.

Figure 5 1s a perspective detailof the cam is a perspective detail of the locking pin.

Like'numerals of reference indicate cornoting parts in the various figures.

eferring to the drawings, the handle 1 of. the operating cam 2 and jaw 4.- is formed with the outwardly ofl'set grip 5. The cam 2 is arc-shaped on its face 6 and its pivot point 7 is situated-adjacent to the back 8, in fact the back 8 is slightly extended, so that the radii of the circular.

paths of travel of the cam 2 and jaw 4 in door toit 's closed position,

their operations may be properly dimensioned for clearances.

' The locking pin bar 9 pro'ects laterally from the handle 1 a short istance above the ip 5 and is slotted at 10 for a pin.

T e pivot plate llcarries the pivot 12 for the cam 2 and is rigidly secured by the bolts 13 to the car door. or Well here shown as fastened to the car door 14.,

The cam wedge 15 projects outwardly from the plate 16 secured by the bolts 17 to the car wall 18 and formed with the flat back 19 in engagement with the cam 2 in opening operations and the V-shaped. wedge faces 20, the lower wedge face surface forming the wedging surface in closing operations in contact with the jaw 4. Y

The locking pin bracket 21 is secured to the car wall 18 below the cam wedge 15 and is formed in T-shape having the arm 22 through which the bolts 23 secure the bracket in its place and the pin slide 24 in the form of a back recess 25 partially closed in front by the flanges 26 throu h which slides the locking pin bar 9 in the guides 27 and 28 which are integral with the bracket 21.

The locking pin 29 is formed with the head 30 ofiset from the upper end and and swung in a irection away from the "car wall or door as the case may be, but

here in a direction away from the wall post, of course the pin has been 'reviously lifted out from the locking pin ar.

The. outward swin of the handle 1 as fan-as the stop 35 W11 bring the cam facev 6 into contact with the wedge and thereby push the door away fromthe walland as the radii of-the circular paths of the jaw' differ the latter clears the lower endof the cam wedge, furthermore in returning the the point of the jaw will surely clear the lower end of the cam wedge and lin'bringing thehandle downthe.

jaw will engage the cam wedge on the wedging face anddraw the door to the 'wall when the pin can be slipped through the lockin pin' bar and shoved downwardly to wedge against a flange 26 to which it is locked by a car seal.

What I claim is:

1. In door fastening mechanism, a combined jaw and cam and-cooperating member. a handle from said jaw and cam having a locking pin bar projecting laterally therefrom, a locking pin bracket having guides for said bar and a locking pin slidably mounted in said bracket and adapted to pass into said locking pin bar.

2. Indoor fastening mechanism, a combined opening and closingmember having a handle extension, and a locking rojection therefrom, a locking pin bracket aving a pin recess and flanges guarding said recess, and a lockin pin havin its head extending into saicI recess an slidable therein and formed in wed shape to abut one of said flanges, said pm and the abutting flange having registering slots for a car door seal.

3. In door fastening means, a combined opener and closer pivotally mounted and operating from a handle terminating in an offset grip, a fulcrum member cooperating with said opener and closer, a bracket, a wedge pin slidable therein and a slotted locking bar pin extending into said bracket I and rigid with said handle.

Signed at Montreal, Canada, this 14th day of February, 1922.
