DOOR-FASTENING FOR MOTOR-CARS, CARRIAGES, AND OTHER VEHICLES.

; Specification of Letters Patent.

Patented J an. 1, 1918.

Application filed August 11, 1915. Serial No. 44,903.

To all whom it may concern:

Be it known that 1, JAMES CHARLES BALLS, subject of England, residing at 30 Hampton road, Shefiield, in the county of York, England, have invented new and useful Improvements in Door-Fastenings for Motor-Cars, Carriages, and other Vehicles,

of which the following is a specification.

This invention relates to a door fastening for motor cars and carriages and other vehicles, and has for its object, in addition to the ordinary slam latch bolt, the provision of asafety grip device, combining utility and reliability with simplicity of construction. My improved door fastening has an advantage overthe ordinary type of carriage door fastenings inasmuch as it provides an extra grip, which insures a. secure locking action by means of turning the handle a quarter of a turn more from its normal position. These advantages, in combination with the ordinary spring latch action render my invention of special value as it gives to the traveling public greater security than with the carriage door fastenings of the ordinary type. It should here be stated that this 1nvention is not claimed in connection with safe looks, not being suitable for use in connection with stationary objects such as steel or iron safes, and pertains only to the temporary fastening of the doors of cars, carriages and the like moving vehicles.

My invention will be better understood on reference to the accompanying sheet of drawings in which,

Figure 1, is a side view of my improved fastening in its normal position to act as a slam latch.

Fig. 2, is an end view of the striking plate employed with my improved fastening.

Fig. 2, is an underside view of same.

Fig. 3, is a similar view to Fig. 1, but showing the bolt of the fastening locked in engagement with the striking plate.

Fig. 4:, is a further view showing the bolt entirely withdrawn into the casing.

Fig. 5, is a right hand end view of Fig. 4.

The same letters refer to similar parts throughout the several views.

According to my invention I construct my improved car or carriage door fastening with a beveled head spring-slam latch bolt, I), with a side grip, a which is made by an extension on the underside of the beveled bolt head, a, of the bolt, 7), (not a deadsquare-head as others locked with a key) for gripping the door. and its doorpost together,

without a key as hereinafterdescribed. The

bolt, Z), is formed with, an opening, 6 for the reception of a single armed follow, 0, the

arm, d, of which as it is moved under the in,-

fluence of the door handle, .a'ctuates the bolt when it bears upon the lug, 6 ,(to withdrawthe bolt) or-fiange, b of ,the said bolt (to butt lock it). Any suitable form of spring or springs may be employed in connection with my invention, but by preference I em ply a double armed wire spring, h, the vertical arm, 5, of which giving a forward movement tothe bolt, and the horizontal arm, 71, lifting the 'bolt and keeping it inv the upper part of the bolt hole, y, in the front plate, j, ofthe. casing, in its normal position for the slamming action. The bolt, Z), is guided in its backward and forward and up and down-movements by means of pins, 6, e, e, e, secured to the casing, moving in right angled slots f, ",-f, formed in the bolt itself.

In Fig. 1 of the drawings, the bolt is shown in its normal position, when it would act as a slam latch and would be self-operating when the door to which my improved fastening was attached, was pushed or slammed to. l/Vhen it is desired to securely fasten the door in its closed position, the follow, 0, and arm, d, would be turned to the position shown in Fig. 3, whereby the grip a on the head, 0;, of the bolt, (2, is forced downward against the action of the horizontal arm, 71?, of the spring, 7L, and effectively locks the door to the side post by reason of the grip,-0; passing down behind the portion, 71 of the striking plate, 2'. It will be observed that when in this position the pins, 6, are at the upper ends of the vertical portions of the slots, 7, and the follow arm, cl, is directly under its pivoted center and at right angles to the flange, b so that it cannot be released by the motion of the vehicle or any other similar cause. On the door handle being turned upward to the right the follow arm, cl, is withdrawn and the bolt is forced upward by the horizontal arm, 7L2, of the spring, 72.. By a further quarter turn of the handle the bolt can be drawn back into the casing (preparatory to opening the door) by means of the follow arm, d, engaging with the lug, g, (as shown in Fig. 4) and in this case it Will be seen that the pins, 6, are at the extreme. forward ends of the horizontal portions of the slots, f.

The form of striking plate I employ in connection with my invention is shown in Fig. 2, wherein it will be seen that the lower portion, '5 is made longer than in ordinary striking plates, in order to receive.the.ex tension, [4 of the bolt head, a, when ina gripped and locked position.

Having now described my invention, what I claim as new and desire to secure byLetters Patent, is

1. In door fastenings for motor cars, carriages, and other vehicles, the improved formation and construction, comprising a bolt head provided with an extension on its underside to grip the striking plate of the door post, a bolt having right angled slots engaging with fixed pins on the casing, and

having a central opening provided with a depending lug and a flange, a single armed follow adapted toengagew'ith said lug and flange, and a double armed spring to give a forward and also an upward movement to the bolt, substantially as herein described and illustrated on the accompanying draw: ings.

2. In door fastenings for motor cars, car

riages, and other vehicles, the improved means, consisting of pins in the casing, a bolt having right angled slotsengaglng sa d pins and adapted to move in right angular directions, and an extension on the underside of the bolt head to engage behind the striking, plate whenuthe said bolt is in its fastened position, substantially as herein described and illustrated on the accompanying drawings.

3.111 a spring latch, a spring-slam latchbolt having ahead formed with a depending projection adapted to engage and hook over the striking plate, meansto normally hold the bolt in protracted position but free of hook engagement with the striking plate, and means for moving the bolt to cause the said projection to engage andhook over the striking plate. v

l. In a spring latch, a bolt, means for normally returning said bolt automatically to protracted 7 position, a projection on, the headof said bolt at right angles to the direction of said motion, and ineans for move, ing said bolt in the direction of said projection whereby said projection engages the striking plate. and is positively 'held in ocked position.
