CHARLES S. MCCARTHY, OF TOLEDO, OHIO, ASSIGNOR TO AMERICAN SWISS MAGNETO COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.
DOOR LATCH.
Application filed February 5, 1925. Serial No. 6,938.
This invention relates to latch mechanisms of the type particularly adapted for use in automobile doors.
An object of the invention is the provision of a light, simple and inexpensive mechanism of the class described, which is capable of having its parts easily and quickly assembled, and is strong and durable in its construction.
Other objects of the invention reside in the construction of the bolt and latch mem her; the manner of connecting the inside control means with the bolt, and the manner of forming and mounting the pinion of the latch control means on the shaft.
The invention is shown by way of illustration in the accompanying drawings, in
which Figure 1 is a side elevation of the latch mechanism Fig. 2 is a section on the line 2-2 of Fig. 1;
Fig. 3 is a view similar to Fig. 2 showing the operation of the mechanism;
Fig. 3 is a plan view of the blank from which the latch is formed;
Fig. 1 is a section on the line 47-4: of Fig. 3;
Fig. 5 is an edge view of the latch show ing the manner of forming;
Fig. 6 is a perspective of the operating shaft and associated mechanism for retracting the latch;
Fig. 7 is a section on the line 7-7 of Fig. 6;
Fig. 8 is a section on the line 88 of Fig. 1, and
Fig. 9 is a plan view of the blank from which the toothed sectors are formed.
The preferred embodiment of the invention illustrated comprises a substantially rectangular metal supporting plate 1 secured to the door D by screws 2 and provided at one end of the plate is an upwardly and out wardly inclined flange 3 which fitsover the end of the door. The flange 3 is provided adjacent the supporting plate 1 with a rectangular'opening 4 through which a latch bolt 5 may project for releasably securing the door in closed position, as will readily be understood. Mounted upon the supporting plate 1 is a guide plate 6 having tongues 7 which are arranged to project into slots formed in the flange 3 on opposite sides of the opening 4. The opposite end portion of the plate rests on lugs 9. and also on the bearing blocks 26 by which it is held in spaced relation to the plate 1, theguide plate 6 being secured to the plate lbyscrews 9 Formed in the guide plate 6 and extend ing a substantial distance therein is an elongated opening or slot 10 within which the latch bolt 5 is slidable, and for maintaining the latch in proper position within the opening 10 a bridge 11 is fixed to the guide plate 6 extending across the opening 10, and
outwardly and inwardly projecting guide flanges 12 extend over the opening 10 adjacent the rear end thereof. The latch bolt 5.is normally held in advanced position within the guide opening 10, and for this purpose a coil spring 13 bears at one end against the inner end of the latch bolt and the opposite end is fixedly secured in any suitable manner to the lugs 9.
For simplicity and cheapness in manufacture and to provide a sturdy and rugged construction the latch bolt 5 is formed from a single blank B of relatively strong sheet metal. As indicated in Fig. 3 the blank B may be said to comprise a long plate 1 1 and a short plate 15 which are integrally connected. In forming the latch bolt the short plate 15 is folded on the dotted line 16 in such a manner as to extend substantially parallel with the plate 14, the short arm curving upwardly and inwardly from its connection with the plate 14. The outer end portion of the plate 15 is bent substantially along the dotted line 17 toward the plate 14 at approximately right angles to form a tab 18. Integral with the side margins of the plate 14: are flaps 19, which are bent substantially along the dotted line 20 at approximately right angles to the plate 14, thereby to support and reinforce the plate 15, each flap 19 being notched so that when the parts are bent after the manner described an elongate longitudinal slot 21 is .formed'for a purpose hereinafter described.
The outer end portion of the plate 1 1 is bent substantially along the dotted line 22 at approximately right angles thereto to provide an upright bearing portion 23 for one end of the coil spring 13. Formed in the side edges of the plate 14 are teeth 24 which constitute arack, which may be engaged for retracting the latch. From the above it will be observed that a latch bolt constructed in the manner described can be manufactured at a relatively low cost in large quantities without sacrificing features of reliability or stur-diness in construction.
F or retracting the latch bolt 5 from the advanced position normally maintained by the action of the coiled spring 13 so that the door D may be opened by occupants within the vehicle, a vertically cisposed ope-rating rod or shaft 25 extends transversely of the supporting plate 1 and the outer end thereof projects above the door to which a handle H may be attached in any suitable or preferred manner. Mounted on the end portion of the rod 25 is a pair of journal blocks 26 which lit between and serve to space the plates 1 and 6' and have opposed projecting surfaces 27, which are shaped to extend into openings formed in the supporting plate 1 and guide plate 6, respectively, for holding the journals in properly assembled relation.
Secured to the rod is a pair of toothed sectors 28, which are arranged to engage the rack 21 for retracting the latch bolt 5 from its advance position. Conveniently the toothed sectors 28 are formed from a blank as indicated in Fig. 9 having a body portion 29, the sectors having openings 31 for receiving the shaft 25. In applying the blank to the operating shaft the toothed sectors are first folded toward each other to extend at substantially right angles to the body portion 29 and thereafter the body portion may be bent around a squared shaft portion 25 and securely held in place by friction or in any other suitable manner. As indicated in Figs. 2 and 8, the toothed sectors 2-8 are movable in slots 32 formed in the supporting plate 1 and normally the sectors are held in the position indicated in Fig. 2 in which the sectors are out of engagement with the rack 24 for a purpose hereinafter described. F or yieldingly holding the sectors in this position a coiled spring 33 encircles the operating rod 25, one end of the spring being fixed to the rod and the opposite end fixed to the supporting plate 1.
As is customary in latch mechanisms of this character, a member is provided extending at substantially right angles to the operating rod 25 for retracting the latch bolt 5, such means usually extending outside the door D so that persons outside the vehicle may readily unlatch the door. For this purpose a lever 34 is pivoted to the supporting plate 1 and is provided with an arm 35 extending into the longitudinally elongate slot 21 of the bolt. The pivot of the lever 34- is formed with a substantially rectangular opening 36 to receive a similarly shaped rod 37, which extends outside the door D and is provided with an operating handle or knob A 38. It Will be apparent that by turning the knob 88 in a counter-clockwise direction 1,5es,see
(Fig. 2) the arm 35 will abut against the end of the slot 21 and further movement thereof will retract the latch bolt from the advanced position.
In order to limit the advance of the latch bolt 5 under the action of the coil spring 13 the lever 34: is formed with an arm 39 having a notch 40, which is arranged to abut against a stop et-l formed on the supporting plate 1. in this manner movement of the lever 34; in a clockwise direction (Fig. l) occasioned by the advance of the latch bolt 5 will move the arm 39 against the stop all and check further advance. In order to adapt the mechanism for attachment to doors having different swinging movements the lever S t may be readily disengaged and mounted in the opening 42 on the opposite side of the guide opening or slot 10, a stop an being provided on the plate 1 for a purpose similar to the stop etl. The operation of the lever in this position will be readily apparcut and further description thereof is deemed unnecessary.
An outstanding characteristic of this invention consists in the unique construction of the latch bolt which may be constructed from a single piece of metal bent into the desired shape as has been pointed out. A further feature resides in the actuating mechanism in which a plurality of toothed members cooperate to enable the latch to be readily and conveniently retracted, thus insuring positive retraction and at the same time providing a construction which may be manufactured at a minimum cost. The latch has proved to operate satisfactorily and efficiently and is a marked improvement over similar mechanisms at present in use owing to its marked simplicity, easy assembly, low manufacturing cost and ruggedness of con struction. Owing to the unique operation of the parts a thinner construction is permitted than similar latches heretofore in use.
