Application filed December 13, 1926. Serial No. 154,444.
The present invention is designed to simplify foot bolts making an efficient structure of this type that may be very inexpensively produced. Features and details of the invention will appear from the specification and claims.
The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a perspective view of the bolt in place on a door.
Fig. 2 a sectional view of the bolt on the line 2-2 in Fig. 3.
Fig. 3 a front elevation of the bolt.
1 marks the door, 2 the floor, and 3 a bolt socket in the floor. The foot bolt has a back plate 4 formed of a piece of strap steel. The back plate is secured to the door by screws 4 extending through perforations in the back plate. The back plate has an out-turned lower end 5 with a bolt guide opening 6 therein. A bolt 7 extends through the opening 6 and is adapted to be received by the socket 3. A bolt extension 8 extends through a bolt opening 9 in an out-turned upper end 10. The bolt has a foot shoulder 11 formed by bending the bolt extension.
A spring 12 is in the form of a loop, the ends of the loop being secured under fingers 13 which are struck up from the metal of 0 the back plate. The spring engages the bolt frictionally and with sufficient force to re' tain the bolt in its elevated or lowered position.
A retracting lever supporting loop 14 is formed in the back plate and has bolt openings 15 in the end, portions of the loop through which the bolt extension extends.
The bolt has aslot 1.6 into which a retracting lever 17 projects. The retracting lever extends through an opening in the outer face of the loop 14- and is pivotally mounted on a pin 19 carried by cars 20 at the sides of the opening 18, these cars being formed of metal struck up from the face of the loop and from that portion of the loop in which the opening is formed. The retracting lever has a corrugated extension 21 which may be readily engaged by the foot to retract the bolt.
The bolt can be readily forced into latching position by pressure on the shoulder 11, or retracted by pressure in the retracting lever in the usual manner. Among the outstanding features of this structure are its simplicity and cheapness.
WVhat I claim as new is 1. In a foot bolt for doors, the combination of a back plate having an out'turned lower end, said lower end having a guide opening therein and an outward projection above the out-turned lower end, said projection having a boltopening therein and a retracting lever opening therein; a bolt in the guide and bolt openings; and a retracting lever engaging the bolt extending through the retracting lever opening and pivotally secured on the projection.
2. In a foot bolt for doors, the combination of a back plate having an out-turned lower end, said lower end having a guide opening therein and an out-turned loop above the lower end having bolt openings in the bottom and top walls of the loop and a retracting lever opening in the face of the loop with outwardly extending cars at the edge of said last-mentioned opening; and a retracting lever engaging the bolt extending through the retracting lever opening and pivotally secured between the ears.
3. In a foot bolt for doors, the combination of a back plate having anout-turned lower end, said lower end having a guide opening therein and an outward projection above the out-turned lower end, said projection having a bolt opening therein anda. retracting lever opening in the projection, said back plate also having spring retaining fingers struck up therefrom; a bolt in the guide and bolt openings; a retracting lever engaging the bolt extending through the retracting leveljopening and pivotally secured on the projection; and a spring in the form of a loop frictionally engaging the bolt having its ends extending under the spring securing fingers.
In testimony whereof I have hereunto set my hand. 1
