SPECIFICATION forming part of Letters Patent No. 588,834, dated August 24, 1897. Application filed February 9,1897. Serial No. 622,618. (Nomoiiel.l

The hasp B for the door A is made hollow and connected with several of the pipes B so that in case one of the pipes B B or the hasp B is cut by a prisoner or burglar air passes into the hollow pipes or hasp to break the vacuum and/to cause the sounding of an alarm, as above described in reference to Fig. 1.

Nowit will be seen that by the arrangement described great security is obtained for prisoncells, treasure-vaults, cages, and the like, and any attempt to break the doors, walls, windows, and the like is at once signaled to the central office to notify the authorities of the occurrence. The several pipes forming the gratings or bars are connected with each other by suitable Ts, elbows, or other fittings, or the pipes may be soldered together or otherwise connected with each other, it being, however, understood that they are always in communication with each other to permit of forming a vacuum therein, as above described.

\Ve are aware that gratings, doors, and the like have been made of pipes filled with water, air, or other fluid under pressure, but we do not claim such an arrangement.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1-. A prison-cell, vault, cage, &c.,'provided with a network of connected pipes forming the wall, grating, door, or the like, a pipe leading from the said pipes and adapted to be connected with an exhaust device, said pipe having an outlet adapted to be closed by a springactuated cover, and an alarm operated by said cover, substantially as described.

2. A prison-cell, vault,cage, 820., provided with a network of connected pipes forming the wall, grating, door, or the like, a pipe leading from the pipes and adapted to be connected with an exhaust device,.said pipe havin g an outlet adapted to he closed by a springactuated cover, an alarm operated by said cover, and an indicator in the said pipe, substantially as described.

A window-grating made of a series of connected pipes, a pipe connected With the said grating and leading to a central ofiice, means for exhausting the air from the said pipe and grating, and an alarm-valve held on the said pipe and closed by atmospheric pres sure and adapted to he opened by a spring, and an alarm adapted to be sounded on the opening of the said valve, as set forth.

4. A window-grating made of a series of connected pipes, a pipe connected with the said grating and leading to a central office, means for exhausting the air from the said pipe and grating, an alarm-valve held on the said pipe and closed by atmospheric pressure, and adapted to be opened by a spring, an alarm adapted to be sounded on the opening of the said valve, and an indicator in the said pipe, substantially as shown and described.

5. A door formed of a series of connected pipes, a pintle connected with the said pipes and having an extension, and a pipe leading from the said extension to a central office, the said pipe being provided with an alarm-valve adapted to be opened by spring-pressure on breaking one of the pipes, substantially as shown and described.

6. A door formed of a series of connected pipes, one of which serves as a pintle, and provided with a hollow hasp connected with sundry of the pipes, and a pipe connected wit-h the pipe forming the pintle and adapted to be connected with an air-exhaust device, said pipe having an outlet adapted to be closed by a cover normally held open by a spring, substantially as described.
