ALFRED HABERSTUMP, OF GRAND RAPIDS, MICHIGAN AUTO DOOBLATCH Application filed October 13, 1930. Serial No. 488,269.

My invention relates generally to latchesand more particularly to a latch adapted 'to be applied to the usual swinging type of automobile door.

One defect of doors for automobiles, as at present manufactured, is that the lu s which protrude from the edge of the d oor and which seat in tapered recesses in the frame portion of the body member, tend to wedge in position when the door is forcibly closed and thus hinder the door from being readily opened. That is to say, these projecting and interengaging lugs, commonly known as dovetails, serve to maintain the door in such position when it is closed that the latch member is located directly opposite its keeper. Also, the engagement of the male and female parts holds the door firmly away from the top and bottom sills of the door and eliminates any up and down movement when the body of the automobile is distorted by. an cause.

Another efect now existent is that it is necessary to manufacture this guiding device, entirely separate from the intermediate latching member, In other words the several parts are entirely separate anddistinct from each other and must be applied separately. both to the door and its frame and hence are more expensive to use.

Now, in my improved device I obviate and overcome the above recited dlsadvantages as well as obtain several meritorious featureswhich will herein be set forth and which will be readily understood from a reading of the instant specification.

Briefly described, my invention consists of a rigid member or arm which protrudes from the swinging door and which enters 40 a slot in the keeper member. Immediately abovethis arm is my novel latch member which is slotted both on its upper edge and along its end, the top slots serving to hold the door in a closed position when it is pushed shut without turning the handle member and the end notch serving to be engaged by a projection on the keeper memher when the door is pushed shut while the handlemember is held with the latching i' bolt retracted during the closing thereof and after closing the handle is released. The first referred to notches engage the vertical sliding member in the keeper unit when the door is properly closed while the notch in the end of the latching element engages when the door; is improperly clos'ed.

Another feature or advantage of my device is that the rigid member which extends from the door not only serves to guide the door to its proper closed position, as other devices of this character likewise do, but no difficulty is had in releasin the same because the latch member, sli ably engaged thereon, is adapted to be withdrawn by tuming the handle on the door whenever releasing and opening of the door is desired. Therefore, the rigid guidemember is freely released. V Y Another advantage which Iobtain is a cheapened construction over those previously manufactured without losing any of the desirable or necessary results previously obtained. I accomplish this by combining the two devices usually used lnto a single mechanism as shown. That is, the guiding device is integrally formed with the latching mechanism. Furthermore, the latch, being placed about one-half way upon the door,

allows for the symmetrical locating of the guiding member. a Other objects will become apparent from the following description taken in connection with the accompanying drawings, in which, v I

Fig. 1 is'a horizontal sectional view taken '85 through the body of an automobile showing my invention applied to the door thereof. Fig. 2 is a side view of Fig. 1, certain parts being broken away in order to expe- 9o dite the disclosure.

' i Fig. 6 is a side view of the casing or housing for the keeper mechanism. 1

Fig. 7 is a vertical cross section through the keeper mechanism, and

Fig. 8 is a view taken along the line 88 of Fig. 7.

Like numerals refer to like parts in the several figures of the drawings.

As shown in Figs. 1, 2 and 5, 10 indicates the handle member of the door 11 which is hingeably mounted upon the main body 12 of an automobile. A member 13, rigid with the handle member, see Fig. 2, cams against the slide 14 and retracts it against the action of the spring 15, this slide being held in place by the headed rivet 16. The outer end 9 of the slide 14 extends through the edge of the, door as clearly shown in the drawings and is formed with teeth l7 on its upper or top surface, while a vertical tooth 18 is formed on its outer end. A rigid extension 19 extends from the door immediately below the latch bolt or element and su ports the same. The end of the latch bol t or element lies substantially even with the end of the supporting means; 19 when the door is in-its properly located position.

The structure just set, forth operates in the usual manner. That is, by turning the handle 10, the member 13 rides against the sliding structure 14 and retracts it against the action of the spring 15, thus moving the outer end 9'to the left and disengaging the teeth 17 from contact with the keeper slide member 20.

The keeper slide member is constrained to move in a predetermined vertical path in the casing member 30 due to lugs 21 extending therefrom and riding in the grooves 31 of the casing. Springs 22, see Fig. 7, force the keeper member downwardly.

A rubber pad 23 rests in the casing at the bottom thereof and yieldably engages the extension 19 when the automobile door is swung shut. A shell 24 protects the rubber and extends through the bottom of the casing as clearlyshown in Fig. 7, thus permitting vthe rubber to compress, if necessary.

The casing member has slots 32 near its top and bottom adapted to receive bolts 33 which extend into the frame of the automobile and maintain the keeper unit in place. A plate 34 forms the front or cover of the casing member and is cut away as at 35 in order to providea path for the latching element.

The operation of my device is readily understood. Assuming the door to be open one grasps the handle and without turning shown in Fig. 7 and prevent the door from swinging open. At the same time that the above occurs the rigid member 19 contacts with the metal member 24 and rides thereagainst and thus causes the latch to exactly correspond in position with its keeper member. When one desires to release the door from its closed position the handle 10 is rotated'and withdrawal of the latching element occurs. During this withdrawal the rigid member 19 becomes loose and unwedged and hence no difiiculty whatsoever is had in opening the door.

Should one improperly close the door .by rotating the handle 10 with a corresponding withdrawal of the latching element inwardly into the door in which it operates, the tooth 18 will tend to contact with the groove 28 thus preventing the door from opening but yet failing to maintain the door in its fully closed position. Thus one will be aware of the fact that proper closing has not occurred and will again open the door and push it shut without turning the handle 10, thus obtaining proper holding. of the door in its closed position. spring 15 tends to push the slide 14 inwardly so that the latching element would slide home to its proper position but ordinarily the spring 15 is not powerful enough to accomplish this effect. However, the outer edges of the keeper member 20 are slightly rounded and oftentimes proper closing of the door is had without the above manipulation.

It will be observed that, in the device as described above, the latch bolt functions in the space between the opposed resiliently supported clamping members or elements or, as defined in the appended claims, the wedging zone or zone of wedging action, this arrangement being advantageous in that it permits great economy of space and simplicity of design, thus facilitating manufacture, lowering cost, and providing a device which can be applied readily to the door and door frame members of a vehicle without making any material changes therein or substantial departures from standard practice.

Having thus revealed this invention, I claim as new and desire to. secure the following combinations and elements or equivalents thereof, by Letters Patent. of the United States.
