Description

Aug. 6, 1935. R. JONES 2,010,723
DOORLATCH Filed NOV. 8, 1954 Patented Aug.Y 6,l 1935 f UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to door latches and the general object of the linvention is to provide a door latch of an extremely simple construction which may be readily applied to a door and which l is extremely cheap to manufacture.
My invention is illustrated in the accompanying drawing, whereim- Figure l is a vertical fragmentary section through a door showing my latch applied thereto, the latch being in elevation.
igure 2 is a horizontal section through a door and door jarnb showing the latch in plan View, the handle 2t being in section.
Referring to the drawing, l@ and il designate two opposed plates designed to go on each side of a door and be held in place thereon by the half inch bolts I2, carrying thereon the nuts i3. These plates le and l l are slotted for the passage of the lever latch M, this latch member being pivoted upon a transversely extending pin I5, extending through the latch I4 and extending through openings in the heads of the bolts I2. This pin I5 constitutes a pivot pin for the latch This latch at one end is curved in one direction, as at I6, to form a handle and at the other end beyond the plate ll, the latch is connected to a retractile spring l'i in turn connected to an end of a bolt it which extends through the upper ends of the plates lil and II. One edge face of the latch facing the door frame beyond the plate It is formed with a notch i9, one wall of which extends inwardly on an incline from the edge face of the latch so that this notch is ratchetshaped.
Extending over the opposite end of the latch is a guard 2t, which is approximately U-shaped and made of a strip oi metal, this guard being turned inward at its ends, as at 2 I, and these ends being apertured for the passage of the bolts I2, the nuts I3 bearing lagainst these inturned ends of the guard.
C'oacting with the latch I4 is a keeper plate 2?. adapted to be attached to the jamh of the door by screws 23. The end wall of the notch i3 is ada-pt- 5 ed to engage over the corner Eil of this keeper.
It will be seen, of course, that the spring I'I urges the notched end of the latch downward and that as the door closes the latch will ride up over the corner 2li of the keeper .22 and then fall into place A10 behind the keeper, latching the door closed. vBy i lifting the end of the latch i6 or depressing the opposite end of the latch, the door may be opened.
It will be seen that the latch is composed of Very few pieces and these very cheaply made and that the latch is very simple to operate.
It will he seen that the guard 2t constitutes a handle for the door and at the same time it acts as a guard to prevent stock from working the latch and opening the door as they do in many makes of latches. When, however, the operator grasps the handle the ngers naturally push against the shank I4 to open the latch.
What I claim is:- 25
A latching structure of the character described, comprising opposed door clamping plates, bolts passing through the plates and adapted to pass through the door, the plates being slotted, a latch having a shank extending through the slots, a pivot pin upon which the latch is mounted having its ends extending through the bolts, a spring engaging the latch at one end and urging the other end of the latch downward, the last named end of the latch havingY on its under face a ratchet-shaped notch to engage over a keeper and a U-shaped guard extending around the opposite end of the latch from the notch and having inwardly extending ends through which the bolts pass.
HORACE R. JONES.
