4. Claims. (Cl. l29) The principal object of this invention is to provide a combination bolt lock and sliding latch and to provide the construction in a compact and simple form in which the unit can be manufacturedand applied to the door very inexpensively; to provide a construction in which the locking bolt and the spring latch will be located closely together on the same structure, andto provide an improved latch in which there is no need for turning'any knob in order to operate the sliding latch.
Other objects and advantages of the invention will appear hereinafter. Y
Reference is to be had to the. accompanying 'drawing, in which Fig. 6 is a side view of the head of the cylinder,
and
Fig. 7 is a sectional view on the line '7-7 of Fig. 2.
The invention isshown in a form in which it 1. as will appear. 40'
is suitable for application to locking the door 10 of adash board compartment 11 for automobile use but, of course, it is capable of general use and not limited to this particular adaptation.
' The lock itself comprises a ilat plate 12 having perforations by which it is secured as by means of rivets 13 or the like to the door. This plate has an end 14 bent at right angles and pro-- vided with a slot 15 through which the bolt passes type and'will notbe described in detail but it has an eccentric stud 17 for engagement in a slot 18 in the bolt 19 which is a simple sliding bolt. The bolt 19 is housed in a three-sided cas 2mg 20, which has integral projections 21 passing through the plate 12 and riveted over on the front thereof to hold the guide casing in permanently fixed position. The plug 16 is located in a cylinder 22 which has lugs 23 passing through openings in the plate 12 and riveted over inside to hold it in place.
In the present instance the end of this fixed cylinder which, of course, projects out beyond the door is knurled at 24 to act as a grip by which the door can be opened without turning any knob.
ing it. the key may be inserted and turned so that the The lock plug 16 is of the usual The key is inserted through the open end of this cylinder 22into the plug 16.
On the guide casing 20 is fixed a plate 25 of sheet metal having two integral projections 26, both perforated to receive the rod 27 of a sliding latch 28, one of these perforations being large enough to receive the latch bolt itself. A spring 29 normally but yieldingly forces the latch bolt into latching position and a pin 3o stops it. The end of this latch bolt is made on a circular convex curve 31 so that it will slip into an opening 32 in the wall of the compartment 11 and constitute a surface which will hold the door closed under ordinary circumstances but will yield on account of the cam end 31 on the application of suficient force. The curvature of this cam end 31 is made on the arc of a circle with its center beyond the axial line of the latch bolt. 5
In ordinary use the door will be snapped in closed position'by this latch bolt merely by clos-" If it is desired tolock the compartment bolt 19 will lock it in the usual way. It will be impossible to open it without the correct key. When the door is closed but not locked the snap latch bolt will keep it closed effectively under ordinary circumstances. The knurled end 24 can be used for opening and closing the door.
By this simple method of construction and as-' sembly of parts, it will be seen that the functions or" a lock and a spring pressed latch bolt are secured in a single structure with very little expense additional to that of the lock and no additional expense in the application of the latch bolt to the door. It furnishes a perfectly good lock and a latch which can be depended upon for holding the door closed, except under severe strains, even when the lock is not in operation.
It will be seen also that in this construction the spring latch is closely associated with the keyoperated lock and the two are in a single structure, thus facilitating the application of both of them to the door. Furthermore no knob has to be turned in order to release the spring latch bolt.
Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in this respect, otherwise than asset forth in the claims, but what I claim isz- 1. In a lock, the combination of a guide casing, a locking bolt movable in a straight line in said casing and guided by said casing, a flat plate secured to the casing having an end at right angles to its plane, provided with an opening through which the bolt passes, key-operated means for actuating the bolt, a plate fixed to said guide casing and having flanges projecting therefrom at right angles and a spring-operated latch bolt guided by said flanges to move in a line parallel to the direction of motion of the locking bolt.
2. In a lock, the combination of a bolt, a key operated lock plug for operating the bolt, a plate by which the lock can be secured to a door, a guide casing for the bolt secured to said plate, a cylinder secured to the plate and surrounding the lock plug proper, the end of said cylinder being roughened to enable it to be used for opening and closing the door.
3. The combination with a lock having a'keyoperated locking bolt and a guide casing for the bolt, of a plate fixedly secured to said casing and having flanges at right angles thereto provided with perforations, of a latch bolt having a rod guided in said peiforations and a spring for operating the latch bolt, said latch bolt having an end adapted to enter a recess for holding the door closed, said end being provided with a circular convex surface for holding the door against opening under normal conditions.
4. In a lock, the combination of a bolt, a key operated lock plug for operating the bolt, a plate by which the lock can be secured to a door,
a guide casing for the bolt secured to said plate,
a plate fixed to said casing, and a spring latch carried by said second plate.
