UNITED STATES PATENT OFFICE.

HENRY G. MOORMAN, OF ELIZABETH, PENNSYLVANIA.

SAFE.

SPECIFICATION forming part of Letters Patent No. 586,521, dated July 13, 1897.

Application filed March 2 3, 1 8 9 6.

To all whom it may concern:

Be it known that I, HENRY G. MooRMAN, a citizen of the United States, residing at Elizabeth, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Safes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in safes.

A description of the construction and operation will be fully shown and described in the accompanying drawings and specification. Figure 1 is a front view of the safe. Fig. 2 is a side view. Fig. 3 is a sectional view of the safe and door, showing the construction; and Fig. 4 is a View of the bolt-locking mechanism. Fig. 5 is a detail showing more particularly the door and its receiving-opening of the safe.

In constructing the safe I provide a series of cylinders or tubes 1, formed of wroughtiron, some of which have threads cut the entire length upon their inner and outer surfaces and some have the threads out only where the circular edges of the plates 2 and 3 (which form the back and door) are joined thereto. Some of these cylinders or tubes have grooves turned within their inner and outer surfaces, fitted within which are the hardened-steel rings 4, (the section of which is shown in black to better distinguish them from other parts.) The circular plates 2, which form the back of the safe, also have grooves turned. within their faces and provided with hardened -steel rings 4. Each plate is also provided with threads for securing said plates together in the manner shown. The cylinder and back being thus secured together in the manner shown are further secured by the large circular rings 7 The rings 8' are shrunken upon the outer body of the cylinder, affording additional security. The plates 3, forming the door, are provided with grooves and rings A and are secured together similar to those of the back of the safe,

Serial No. 584,442. (No model.)

but said door is capable of being unscrewed from and replaced in the body of the safe by means of the mechanism described herein- Attached to the sides of said boss are the v brackets 20, having pins 21 secured thereto. The friction-wheels 22 surround said pins and are provided with balls, forming a ball-bearing. The surfaces of said friction-wheels operate against the inner edge of the face-plate 24. Secured between the said friction-wheels is a case 25, containing a coiled spring 25 one end being secured thereto, the other being secured to the shaft 17, the object of which is to provide a means of automatically screwing the door in place, which is accomplished by turning the hand-wheel 18 to wind up the spring and securing the same by the ratchetteeth 25 and pawl 26, so that when said pawl is released the spring will act and cause the friction-wheels to revolve against the faceplate. By turning the hand-wheel to unscrew the door the coiled spring is again wound up ready for use. A shaft 27,'secured to the arm 16 at one end and provided with bearings in the bracket 15 and standard 28, has secured to its outer end the gear-wheel 29 and operates with the gears 30 and 31. Said gears 30 and 31 are supported by shafts 32 and 33 on the standard 13. The shaft 32 is provided with a ratchet-wheel 34, and the standard 13 with a pawl 35, said shaft also having a handcrank 36, and said pawl engaging said ratchetwheel. Operating in the teeth of the pinion 31 is a rack-bar 32, inclosed within a cylinder 33, secured to the upright standard 34 and cap 35 Within the said cylinder is a spiral spring 37. The object of said spring and rack is for the purpose of transmitting movement, through the gears, to the liftingarm 16 and door 3, so that when the door is lifted and thrown back uponthe top of the safe the spring 37 will put a tension upon the rack and gears, thereby in a measure checking the fall of the door. By turning the handcrank 36 the door may be lifted up and held by the ratchet 3a and pawl 35, said pawl being provided with a wire for operating the same.

The locking mechanism consists of a flanged case 10, containing the gear-wheel 38. The racks 40, formed upon the plates 39, operate with the said gear. The pins 41 are suitably secured to the said plates. An automatic lock of suitable construction is provided to operate the locking mechanism, said locking mechanism being attached to the inner face of the door by the plate 11. Steel plates 8 are set into the door and back of safe, as shown. Secured to the arm 16 is a small cylinder 42, having a pin or plunger 43 securely held therein by the spring 44, so that when the door is thrown up and rearward the spring will act as a cushion for the plunger, thereby preventing the sudden jarring of the door upon the top of the safe.

The frame 50, upon which the safe is secured, rests upon the truck 51.

To open the safe, the wheel 18 is grasped and properly turned to the left, unscrewing and withdrawing the door from the safe, at the same time pnttin g the spring 25 for subsequently automatically screwing the door to its closed position, under tension. The door when fully withdrawn from its opening in the safe is then elevated, which is effected by grasping and turning the crank 36, operating the gearing 29 30, moving the arm l6,with the door, upward tothe required height, and said door permitted to be dropped back upon the safe, the pin or stop 43 first coming in contact with the latter to relieve concussion or jar,whicl1 would otherwise take place. The

closing of the safe is effected, of course, by just a reverse operation of these parts.

It will be understood that the gear 31 and rack 32 are also operated simultaneously with the gearing 29 30, whereby the spring 37 is put under tension for the purpose above stated.

It will be seen that a safe of this construction is absolutely burglar-proof, as no drill can possibly penetrate it at any point without coming in contact with the steel rings or plates, the construction of the safe, as shown, forminga practically solid cylinder and heads of laminated metal.

Having thus shown and described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a safe, the combination of the rightangled arm connected to the door at one end, the shaft 27 secured to said arm at its opposite end and bearing in a bracket supported upon the safe,the spring-pressed rack, intermediate gearing between said rack and shaft, means for actuating said gearing and means for preventing reverse movement of said gearing, substantially as set forth.

2. In a safe, the combination of the circular door having the face-plate, the hand-actuated shaft bearing at one end in said faceplate, a stationary casing, and the coiled spring connected to said shaft and casing and adapted to screw said door to its place, substantially as set forth.

In testimony whereof I aihx my signature in presence of two witnesses.

HENRY G. MOORMAN.
