Title: Automobile door latch mechanism
IPC: E05B65/32
Filed: 1938-03-01
Abstract: 500,507. Latch mechanism ; handles. ATWOOD, S. B., and ATWOOD, J.-T. March 1, 1938, No. 6483. [Class 44] [Also in Group XIV] A lock mechanism for a vehicle door comprises a spring pressed bolt and a lever operating the bolt, mounted to swing in planes parallel to the edge of the door, retracting means in the form of a handle mounted to swing outwards from the outer face of the door, and retracting means including a rollbaek disposed adjacent the inner face of the door. The bolt 16, pivoted at 34 on one side of an attachment plate 21 fixed on the edge of the door, coacts with a keeper 15 having a main catch face 18 and a safety catch face 19. A pin 39 on the bolt 16 projects through a slot 41 in the plate 21 and engages a slot 44 in a bell-crank lever 42 pivoted on the other side of the plate 21. The bolt is retracted from outside by pulling a handle 51 pivoted on a vertical pin 52, the inner end 50 of the handle contacting the vertical limb 47 of the lever 42 to turn it about its pivot 43. The bolt is retracted from inside by a longitudinal movement of a link 31 which depresses the end 48 of the lever 42 by means of a bell-crank lever 29. The lower edge of the slot 44 in the lever 42 is bent out of line with the pin 39 on the bolt so that when the door is slammed. the bolt rides over the catch faces 18, 19 without affecting the operating mechanism. Operation by the outside handle may be prevented by moving the inside handle in the reverse direction, when the door is closed, which causes the slotted end of the link 31 to slide on the pin 30 of the lever 29 and engage a lug 65, integral with the link 31, in a slot 66 in the plate 21, thus blocking the path of the lever 42. Should the inside handle be moved to the blocking position with the door open, a bellcrank lever 33, pivoted at 32 and extending. through the plate 21, is depressed by the bolt as it engages the keeper and the lower end of the lever 33 pushes the lug 65 out of the path of the lever 42. A flush appearance is imparted to the handle by recessing the door at 55 and placing strips of moulding 57 in line with the handle. In a modification, the mechanism is inverted so that the bolt swings downwardly to engage the keeper. The handle 51a is carried by a removable plug 53a held in place by the engagement of a lug 73 in the inner surface of the door with a recess in one side of the plug and by a screw 74 passing through the plate 13a engaging a hole in the opposite side of the plug. A rubber buffer, carried by the part 58 of the casing, comes between the bolt and the keeper when the door closes, and another buffer 77 is interposed between a shoulder 78 on the handle and the outer face of the plug, to prevent rattle. A revolving barrel lock having a bolt operated by an eccentric on the barrel may lock the door by the bolt engaging a notch in the lever 42 or engaging the handle 51 between its pivot 52 and nose 50.

Abstract: 212,413. Hollingworth, E., (Crompton & Knowles Loom Works). March 10, 1923. Weft-feeler arrangements.-Relates to weftdetecting mechanism of the type comprising a casing or member or slide 11 slidable in a stand 10 and carrying a rearwardly-projecting fixed detector 12 and a movable detector 13 pivoted at 14, these detectors remaining normally in the relative position shown when they are forced back by the weft but assuming an abnormal relative position when the weft is substantially exhausted whereby weft - replenishment is initiated. A rod 15 furnished with an adjusting-screw 18 to engage the stand 10 and with a hook-shaped end 16 to engage the detector 13 limits the rearward movement of the slide and detectors, and a rod 25 slidable in the casing 11 engages a projection 17 on the detector 13 and has a U-shaped portion engaging an arm 28 on a spring-controlled shaft 29. The return bend 26 slides in a recess &c. 38 and an offset end 27 engages a lug &c. 40, thus preventing accidental separation of the parts. Normally, when the detectors and slide are pressed back by the weft, the rod 25 actuates the arm 28 and its shaft 29 but when the weft is substantially exhausted the detector 13 swings on its pivot, the arm 28 and its shaft 29 are not turned, and consequently a rod connected to a further arm on the shaft 29 remains in the path of a lever whereby the replenishing mechanism is actuated. The stand 10 is furnished with a cap 20 provided with a threaded rod 22 furnished with a spring and having a shoulder engaging a bracket 23 on the slide.
