SLIDING-POLE-OPENING GUARD.

Specification of Letters Patent.

Application filed June 22, 1910. Serial No. 568,333.

as is used in fire-engine houses, and has for one of its objects the provision of a device that is capable of being secured to the wall or other upright support at one side of the opening and consisting of two arms so constructed and mounted that when they are in position to guard the opening they form a continuous rail, but when they are moved to expose the opening separate so that the pole does not interfere with their movement.

Another object of my invention is the provision of a device that is actuated by springs into an inoperative position, being held in 'its guarding position by a slidable catch that is released by mechanism connected with the fire-alarm system.

My invention will be described in detail hereinafter, and illustrated in the accompanying drawings, in which- Figure l is a view of the interior of the firemens dormitory, showing the slidingpole and opening with my improved guard in operative position; Fig. 2, a front view in an inoperative position; Fig. 3, a similar view in a guarding position; Figs. 4, 5, 6, and 7, detail views of the hooks on the guard-arms; and Fig. 8, a side view of the latch-bar.

In the drawings similar reference characters will indicate corresponding parts throughout all of the views.

My improved guard may, as shown, be secured to the wall A of the firemens dormitory adjacent to the sliding-pole opening B and at a sufficient height above the floor to form an effective barrier to prevent any one from stepping into the opening accidentally, C designating the sliding-pole.

My guard consists of a base-board 1 secured to wall A and havin journal- boxes 2 and 3 secured thereto, saitf boxes being arranged so that the journal-boxes 2 near the middle of the base are on a higher plane than the journal-boxes 3, adjacent to the ends of the base.

4 indicates the two guard-arms, each consisting of a rod or length of tubing having an outwardly-extending portion 5, with its outer end bent toward the other arm, as shown at 6, while its other end is bent at right angles to the portion 5, slightly upwardly, as shown at 7, and journaled in boxes 2 and 3. By this construction it will be apparent that when the arms are in their lowered position to guard the opening B their ends are together, as shown, but when they are swung upwardly to expose the openings the ends of the arms are thrown away from one another, so that they will pass the pole C without interfering with one another.

8 indicates coil-springs mounted on the ends 7 of the arms 4 and having one of their ends secured to journal-boxes 2 and their other ends secured to collars 9, secured to the arms by means of set-screws 9.

10 indicates a latch-bar slidably mounted on base 1 and held normally in a raised position by lneans of spring 11, and 12 a roller journaled laterally on one side of the bar.

13 indicates a hook secured to the end 7 of one bar 4 and provided with a socket 14 to receive a lug 15 on hook 16, secured to the other bar, while 17 indicates a beveled lug on the side of hook 13 to engage roller 12. From this construction it will be understood that the arms 1 are held normally in their raised or inoperative position by means of springs 8, and when moved manually downward the beveled lug 17 engages the roller 12 and moves the latch-bar 10 downwardly against the resistance of spring 11. When the arms 4 reach their lowermost position, the lug 17 passes from engagement with roller 12 and the spring 11 raises the bar so that the roller comes to rest under the lug 17 and the arms are held in their lowered position against the resistance of spring 8.

18 indicates a casing secured above the latch-bar 10 and having a weighted arm 19 mounted therein, said casing being connected to the fire-alarm system by means of wires 20 and having mechanism therein that holds the arm 19 normally raised, butwhen the alarm is sounded the arm is released and striking latch-bar 10 slides it downwardly, so that the roller 12 is moved from engagement with lug 17 and the arms 4 are swung upwardly by the action of springs 8.

21 indicates an arm secured to the portion 7 of one of the arms 4:, and 22 a rope secured thereto and extending down into the engineroom to permit moving the guard-arms to Patented Jan. 24, 1911.

their operative position from the engineroom,

23 indicates spring-arms secured to base 1 that act as buffers to cushion the arms when they reach their uppermost positions.

24 indicates antifriction rollers for the latch.

Having thus described my invention, what I claim is 1. A guard device for openings in floors and similar places comprising a baseboard, j ournal-boxes secured thereto, arms journaled in said boxes, and springs normally i tending to raise the arms, substantially as 1 the journaled ends of said arms, and a latchbar slidably mounted on said base to engage the hooks and hold the arms extended against the resistance of the springs, substantially as shown and described.

4. A guard device for openings in floors and similar places comprising a base-board, journal-boxes secured thereto, arms jour naled in said boxes, springs normally tending to raise said arms, a hook on one arm 11 and having a socket therein, another hook secured to the other arm and engaging the socket in the first mentioned hook, and a latch-bar slidably mounted on said base to engage the first-mentioned hook when the 1 arms are in extended positions to hold them against the resistance of the springs, substantially as shown and described.

5. A guard device for openings in floors and similar places comprising a base-board, journal-boxes secured thereto, arms journaled on said boxes, coil-springs mounted on the journaled ends of the arms, one end of each spring secured to one of the journalboxes, the other end of each spring secured to the arm and normally tending to raise the arm, hooks secured to the ends of the arms, one of said hooks having a socket and the other hook engaging the socket, the firstmentioned hook having a beveled lug thereon, and a latch-bar adapted to engage the lug aforesaid to hold the arms extended, substantially as shown and described.

6. A guard device for openings in floors and similar places comprising a base-board, journal-boxes secured thereto, arms journaled on said boxes, coil-springs mounted on the journaled ends of the arms, one end of each spring secured to one of the journalboxes, the other end of each spring secured to the arm and normally tending to raise the arm, hooks secured to the ends of the arms, one of said hooks having a socket and the other hook engaging the socket, the firstmentioned hook having a beveled lug thereon, a latch-bar having a roller journaled laterally thereof and adapted to engage the beveled lug, a spring engaging said latchbar to hold it in a raised position, and the roller in engagement with the lug aforesaid, and a weighted arm suitably supported and adapted to be released and strike the latch-bar to move it downwardly and release the roller from engaging the lug, substantially as shown and described.

In witness whereof, I have hereunto set my hand in presence of two subscribing witnesses.

EDWARD C. DELENE.
