SLIDING DOOR-PULL.

SPECIFICATION forming part of Letters Patent No. 287,039, dated October 23, 1883.

Application filed July 25. 1883. (ModeL) To all whom it mag/concern.-

Be it known that I, TrroMAs LYoNs, a citizen of the United States, residing at Hartford, in

the county of Hartford and State of Connectiout, have invented certain new and useful Improvements in Sliding Door-Pulls,of which the following is a specification.

My invention relates to improvements in sliding door-pulls; and the objects of my invention are to so arrange the push-pin and its connecting-lever as to throw the handle out of the door to the full extent of its movement; also, to have the throwing-lever engage the pull and hold it in position when it is either wholly without or wholly within the case. I attain these objects by the simple construction illustrated in the accompanying drawings, in which Figure l is a side elevation of my pull, with the cap of the case removed. Fig. 2 is a like view'of the same, with the pull thrown outward, and with one position of the throwinglever indicated by broken lines. Fig. 3 is a view looking upon the face-plate of my pull, and Fig. 4 is a horizontal section of the case on line as x of Fig. l, with the other parts in elevation as looking upward from below. The case may be of any ordinary construction. I

A designates the pull proper, the inner end or shank, a, of which rests between suitable guides on the case, and its lower edge is pro vided with two holding-notches, b and p. The throwing-lever B is pivoted to the case at d, and to the push-rod C at e. A spiral spring, f, with one end resting against the side of the case and its other end against the end of the push-rod, acts with a constant tendency to hold the push-rod and the throwing-lever in the positions shown in the drawings. When the pull is wholly within the case, as shown in Fig. 1, the arm 9 of the throwing-lever enters the hooked notch Z) on the shank of the pull and positively locks the pull against an outward movement until said lever is withdrawn. By depressing the end of the pushrod the arm 9 is withdrawn from the hooked notch b, and immediately thereafter the arm h of the throwing-lever engages the rear end of the shank of thepull. Byaoontinued movement of the push-rod the pull A is thrown into the position indicated in Fig. 2, and the lever B is thrown into that position which is indicated by broken lines in said figure. Upon releasing'the push-rod the spring throws the rod and the throwing-lever back again, when the hooked arm enters the curved recess 0 in the under'sideof the shank of the pull, and holds the same in its extended position.

recess is not very abrupt, so that the arm 9 can be disengaged from the notch by sufficient pressure upon the outer end of the pull. By referring to the two positions of thethrowing-lever, as shown in Fig. 2, it'will be seen that it has sufficient throw to carry the pull outward to its full extent. The pull is prevented from being thrown or Jdrawn wholly from the case by means of a stop-lug on the case between the two guide-lugs, as indicated by the transverse broken lines in Figs. 1 and 2. The shank of the pull is made thin for the greater portion of its length, and the flat side of said thin portion rests upon said stop-lug. The end of the shank is thickened to form a shoulder, as indicated by the transverse broken The engaging surface of the hook and this rounded 1. The combination of a sliding pull, the

throwing-lever pivoted to the case at d, and having the arm h, which engages the rear end of the shank of the pull and throws the pull outward, the push-rod pivoted to the short end of the throwing-lever, and the spring which acts upon the push-rod to force it outward,

substantially as described, and for the purpose specified. K p

2. The combination of the pull having a holding-notch, b, in the lower end of its shank, the spring-pressed throwing'lever having the arm 9, which engages said holding-notch, and the arm h, which engages the rear end of the shank of the pull, substantially as described, and for the purpose specified.
