wardly to the position shown in Figure 4, whenever the bolt 19 is in downwardly shifted position for purposes presently more fully appearing.
When the door lock A is properly mounted in the door 1, the bolt 19 will engage the jamb 2, as shown in Figure 3, and will hold the door 1 securely in place. The spring 32 and pressure-transmitting element 27 will introduce a limited degree of resiliency which will compensate for wear and vibratory stresses, so that the door 1 will always remain right. In order to release the door lock A and open the door 1, the handle 34 is manually swung upwardly, causing the actuator-tube 38 to engage the pin 23 and shift the latter downwardly, thereby shifting the bolt 19 downwardly against the bias of the spring 32 until the upper end of the bolt 19 is fully retracted and the door 1 is free to swing open. As soon as the grip 35 of the handle 34 is released, the bolt 19 returns to initial position, so that the door 1 may again become locked as it is returned to closed position. Whenever the door 1 is not fully closed, the handle 34 will project outwardly from the cup 4, as shown in Figure 4, so that the driver or operator has an immediate visual signal of this condition and will not accidentally drive off with a compartment door unlatched and free to swing outwardly as the vehicle travels along the street or highway. Such accidents have occurred with conventional door latches and have resulted in injury to pedestrians, as well as the loss of tools and other valuable contents usually carried in the compartments.
The door latch A can very readily and quickly be assembled and disassembled as will be seen from Figure 8. The bolt 19, the pressure-transmitting element 27, and the spring 32 can be assembled within the U-shaped channel and manually held in compressed position so that the pin 23 can be inserted through the slot Sand, at the same time, the flanges 13, 13, 14, 14, slipped into the socket-forming flanges 11, 11, 12, 12', respectively. Thereupon, the cars 18 can be bent over, as shown in Figure 2, to hold the U-shaped channel 15 in such assembled position. The door latch A can, on the other hand, be disassembled with equal simplicity by bending the ears 18 back to upright position and reversing the above described sequence of assembly operations. Consequently, if the spring 32 should break, or any one of the other parts become worn, damaged, or inoperative so as to need replacement, this repair operation can be very easily performed if necessary or desirable. It is also equally convenient, in view of the unique, economical, and compact construction of the door latch A, to remove the rivets 6 and make a complete replacement.
If is also possible to provide a modified form of door latch B, which is substantially in all respects to the previously described door latch A, except that the attachment clips 10, 10', are eliminated and a U-shaped channel 44 is provided having straight-margined lateral flanges 45, 45', which are spot-welded to the back wall 7 of the cup 4'. The U-shaped channel 44 is furthermore provided with a rearwardly presented bight wall 46, which is provided with a relatively large centrally located aperture 47 to permit access to the rear end of the pin 23. In this particular movement, the bolt 19' and the elements associated therewith, as previously described, must be assembled in the U-shaped channel 44 and the pin 23 thereupon inserted from the front of the cup 4'. A suitable conventional peening tool or upsetting tool can be inserted through the aperture 47 so as to upset the rearwardly presented end of the pin 23 and stake it rigidly with a rotatable detent finger 49 adapted, when in locked position, to extend upwardly into endwise abutting engagement against the downwardly presented abutment flange 17', substantially as shown, for example, in Figure 2.
It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the door latch may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
