Description

PATENTED AUG. 8, 1905.
H. P. POPE. GAR DOOR LOCK. APPLICATION mum JULY 26, 1904.
INVENTOR UNITED STATES PATENT OFFICE.
HENRY F. POPE, OF CLEVELAND, OHIO, ASSIGNOR TO THE NATIONAL MALLEABLE OASTINGS COMPANY, OF CLEVELAND, OHIO, A GOR- PORATION.
CAR-DOOR LOCK.
Specification of Letters Patent.
Patented Aug. 8, 1905.
Application filed July 26, 1904. Serial No. 218,243.
To all whom it may concern: I
Be it known that I, HENRY F. POPE, of Cleveland, Cuyahoga county, Ohio, have invented a new and useful Oar-Door Look, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 shows in elevation a car-door lock constructed in accordance with my invention. Fig. 2 is a view of the bolt before it is finally secured to the stud on which it slides, and Fig. 3 is a vertical cross-section of the baseplate stud and bolt when the bolt has been secured to the stud.
My invention is an improvement on the cardoor lock described in a patent of Hopkins & Tesseyman, No. 455,686, dated July 7, 1891. The device shown in that patent comprises a longitudinally-slotted bolt slidingly mounted upon a fixed stud, and as it has been made heretofore the stud has been formed in a separate piece, which has been inserted through the slot of the bolt into a hole in the base-plate and has been secured to the base plate by upsetting its inner end in the manner of a rivet, the head at the outer end of the stud fitting against the front of the bolt and confining it. When the workmen are assembling the parts, the studs are apt to be imperfectly upset, and when this occurs it produces a defective lock. These difliculties are entirely avoided by my invention, in which the stud is made integral with the base-p1ate that is to say, formed on it or permanently fixed to it during the act of casting-the bolt being applied by making it of malleable metal with its slot wider than the head of the stud, so that it may be placed loosely thereon, and then squeezing the sides of the bolt together toward the stud and back of its head, so as to confine it thereon.
In the drawings, 2 is the base-plate, and 3 is the stud, which is cast integral therewith and has a head 3. The sliding bolt 4: is adapted to enter the staple 5 and to hold the hasp longitudinal slot Which fits the stud back of the head and is compressed to a less width than the head throughout the length of the slot; substantially as described.
In testimony whereof I have hereunto set my hand.
HENRY F. POPE.
