CLARENCE VOGT, OF WENONAH, NEW JERSEY, ASSEGNR TO VOGT BROS. & SQUIER COMPANY, 0F PHILADELPHIA, PENNSYLVANIA, A CGRPORATION OF DELAWARE.
Application filed March 3D, 1923. Serial No. 628,704.
This invention relates to latches for doors and more particularly to latches for the doors of automobiles, carriages and similar vehicles, said latches being commonly known in the trade as sheet metal or limousine latches, and among other objects had in view I aim to provide a latch of the foregoing character which is typified by a substantial structure, While being very compact in de- Still further I aim to, and do, provide a.
sheetmetal lock that, while embodying the advantageous features above referred to, is of simple and efficient construction and capable of manufacture at a comparatively low cost.
With the foregoing objects in view this invention consists essentially in certain novel features of construction andthe combinations and arrangements of parts incorporated in the latch hereinafter 'fully set forth, and more particularly defined by the subjoined claims.
In the further disclosure of this invention, reference will be had to the accompanying sheet of drawings constituting'apart of this specification and in which like characters of Vreference designate the same or' corresponding parts in all the views.
Figure I, is an elevation of one practical embodiment of my invention, or novel sheet metal latch,`with part of the base Vmember broken away for a clearer view of the underlying structure. V Y
Figure II is a reverse elevation of the preceding iigure. p f
Figure III is a sectional view taken substantially onthe line III-III'in Figure I, and looking inthe direction ofthe arrows. Y
Figure IV-is a perspective view of thelatch andfassociated stirrup or fork.
Figure V isa perspective view-of the latch i actuatorlor tumbler.'
Figure VI is a perspective view of amodilied form of the latch actuator.
Figure VII is an axial vertical section throughf the form of latch ladtuator hub shown in the preceding figure. i
`Figure VIII is a perspective view of a fuiltlier modified form of the latch actuator; an
Referring more in detail to the drawings and in accordance with the specific embodiment of my invention illustrated thereby the Figure. IX is an axial section through the base member or latch plate 10 is made of sheet metal .of appropriate character and thickness.. rlhis base member or latch plate 10 embodies a. blank of rectangular configuration that is bent along three of its sides to provide flanges 11 at right angles thereto,
and along the fourth side to provide a face plate 12, having countersunk holes 13 therein for the insertion of the necessary attaching screws in the well known manner. Thus it will be seen that the saidbasemember or f latch-plate 1() when formed to provide the flanges 1l and face plate 12 constitutes what may be termed a unitary latch case. The face plate 12 is suitably slotted at 111- for-the free passage of the latch 15, and it has additional `spaced slots or openings 16 therein, for a lpurpose hereinafter setfortli.
The latchV member 15 is made from a substantially rectangular sheet metal" blank stamped out or out away from. one of its sides into lil-formationto provide-a slot 17 and apair of spaced limbs 18,-the free ends wliereofare transversely bent at right angles to constitute supports 19 having central projections 20V which it is to beiremarked are rectangular inV cross sectionA and serve Vto guidingly maintain the latch memberl `in proper alignment as hereafter explained. Thelatch bolt 21'is made of rectangular cross section bar material and it is slotted at 22 from Vits inner endk to receive a slotted extension 2?),med1al of `the aforesaid sheet and 21 beingeifected. by means of depression metal blank '15, union of` the two partsrl 24 appropriately forced into si'iidslotted extensionv23 from the outer face of the latch bolt 21. Or, as will be quite-obvious, the
Vparts 15, 21 may be spot-welded or riveted together', but it beingmy. aim to produceV the icsY entire latch bydie stamping, it'willhe-seen that the forcing of the depression 2li will result in an opposed displacement of metal into the aforesaid slot 22, the same being readily comprehended by those conversant with the art to which my invention appertains. n
Referring again to the aforesaid rectangular projections 2O it is to be observed thatthey a-re a sliding fit in elongated and parallel spaced slots in the main body portion of the base member or latch plate l0, as best seen by Figure I, and they serve to maintain and guide the latch lwith a direct travel and free from any undulatory movement.
The latch actuator or tumbler Q6 is conveniently, also, a unitary metal stamping provided with opposed actuating wings 27, 27, and stepped hub 28 having a rectangular bore Q9 for the reception of the usual operating spindle or lever-not shot-rn. rIlhe usual spring is indicated at 30, and it is apf need not be s0 coimected, but it will be noted propriately coiled around and anchored on a. binding post or pin 3l, with one free` end 32 abutting one of the aforesaid supports 19, while the other free end has bearing on the abutting flange ll as will be readily seen from Figure I, more particularly.
The mechanism above described is conveniently maintained, and securely held, in
assembled relation by means of a complementary plate 34 having ears or lugs 35 adapted to enter vand snugly seat in the spaced slots 16, while said plate 34 is apertured at 36 to receive the shouldered part 37,-Fig. IIIof the aforesaid binding post or pin 3l. This complementary plate 34 is also cut out or slottedatSS to provide an additional lguiding' means for the latch bolt 2l, while it may have vits spindle hole 39 inwardly flared or swaged at' 4:0, to forma spacer bearing for the aforesaid latch actuator or tumbler26 that prevents its displacement, as will be obvious on an examination yof Figure III more particularly.
In some cases where it ma be desirable lthat the latclifactuator or tumbler 26 have actuators or tumblers 26 disposed inreversed relation and spot welded together; or, they that by reversing said tumblersV 267m opposed relation there will be provided a shouldered bearing ll at each side or hub end.V Furthermore, in other instances, where it is requisite that the latch actuator for tumbler wings 27 be relatively nearer one end ofthe vhub portion 26 than the other, I use the device 26" illustrated in Figures VIIIand IX, said @device 26 embracing a substantially A'rectangular spindleghub 4t2 on Anate friction, while ensuring the vouter wall whereof, the actuator or tumbler 26-in this case a flat member-is suitably forced, shrunk or otherwise rigidly secured.
From the foregoing description and an examination of the drawings it will be clearly apparent that by my invention there is provided a sheet metal latch embodying but few parts, all of which can be easily produced by die stamping, while the assemblage of said parts can be effected with a mininium expenditure of time and labor. Still further it will be'remarlred that the respectiye moving parts or members are efficiently designed and correlated to elimirelative movement without the remotest possibility of disruption.l Finally I wish it understood thatL I do not limit myself to the precise form of sheetmetal latchfhereby exemplified and fully explained, but deem myself-,at
liberty t0 malte all such reasonable variations and modified arrangements asf fairly lie within the, scope of the appended claims.
Having thus described my invention, I claim-z 1.In a latch of the type described, the combination of a sheet metal casingr having integral flanges anda slotted face plate, a latch member movable through the slotted face vplate and provided with a forked eX- tension having angled terminal ends slidable inV parallel slots in the aforesaid casing, a sheet metal actuator journalled in the casing and having opposed wingsoperatively engaging the.'l angled terminal ends,r and a closure platehaving an inwardly swaged flare yconcentric with the actuator hub.
