IMPROVEMENT IN PORTABLE SFE-PROTECTORS.

' Specification formingpart of Letters Patent No. 131,842, dated October 1, 1872.

, accompanying'drawing forming part of this specification, in which- Figure lis a front elevation of my invention, showing the front wall or door removed; Fig. 2 is a longitudinal vertical section; Fig. 3 is a view-of the alarm 'mechanism detached; Fig. 4 is a sectional elevation,` showing amodication of my invention; and Fig. 5, a bot-V tom-view of the same. v

Similar letters of reference in the accompanyingdrawing denote the same parts.

This invention has for its object to provide M for public use a portable protector for ordinary re-proof or other safes, which can be used for any safe without particular reference to its construction; and to this end it consists,

mainly, of a double-walled iron case, sufficiently large to inclose a safe of ordinary size,

and provided on all sides with a space which is to be filled with water. It is also provided with a door, which slides vertically in suitable grooves, and is operated by rack and pinion,

the turning of which latter operates an alarmgong located in the inside of the case.

`The details of construction and. method of operation will be more fully described hereinafter. i

A represents a rectangular case, constructed l with double iron walls, Vbetween which is a space, a, of any desired width, which is filled with water. The. space a extends entirely around the case, excepting at the front, which is protected by a door, B, of similar construction, which is provided with a water-space, c. The door B slides vertically in grooves in the front end of case A, and is provided with the vertical rack D, which meshes with the pinion E. This latter islocated on a shaft, F, which runs `across the case A near the front thereof, and is 'suitably journaled in its walls. Said a shaft is provided at one end with a square head, which projects through the case A far enough to engage` the socket of a crank, G, therewith. H represents a disk, which is 1ocated near one end of the shaft F within the `passes through a slot in the end of said lever,

and causing a spring-hammer to strike the gong K. It will thus be seen that, as the shaft F 1s revolved in the proper direction, the pinion E engages with the rack D, and raises the door B. At the same time the pins h of disk H act on the lever I and connecting-rod J in such manner as to strike the gongv at the contact of each of the pins h with the lever, which latter is kept in the position shown in Figs. 2 and 3 bya spring, L. The spaces a o are supplied with water through suitable orifices in 'the upper part of the case, which is also provided with vents for the escape of steam in case of fire. The square head of the shaft F projects into a recess on the outside of case A so that its end is flush with the surface of the same, thereby preventing the revolving of the -shaft by any person unprovided with the proper key or crank G. In case, however, the door should be opened, the alarm-gong always gives notice, as it is impossible to tamper with the latter, it being with the rack and pinion inside the case A.

This arrangement constitutes a simple as well as efcient protector, and can be constructed of any desired size. It practically doubles the security of the ordinary safe without a corresponding increase in cost, its construction being comparatively simple and cheap. If desired, the case can be located on rollers. The safe is held in position within the caseAby jack-screws I', as shown in Fig. 1.

Fig. 4 shows a modification of my invention, which consists of a bottomlcss case, M, which is provided with a water-space, m, and raised and lowered by a chain or other suitable means, the case resting on the floor of an apartment when lowered, and inclosing the safe, which rests on a water-packed platform, which practically constitutes its bottom. The case M and bottom N are locked together by rods n, which pass through lugs O on the lower side,

and are in turned locked by a transverse rod, P, which passes through the ends of rods n and is secured by a suitable lock, R.

I do not desire to claim the idea of protecting safes by water-spaces, nor the broad idea of inclosing a safe in a separate casing, as safes have been so arrangedto be lowered into a vault, for instance; but I am not aware that A, having hollow walls to receive water and an open bottom or side, by which it is adapted to be fitted over an ordinary' fire-prooi' safe, substantially as described, for the purpose speciied.

2. The case A, provided with the verticallysliding door B, operated by the rack D and pinion E, in combination with the alarm mechanisni, consisting of the disk H, lever I, connecting-rod J, and gong K, as and for the purposes described.
