J. F. GAMILLE. MINE VENTILATING APPLIANCE, APPLICATION FILED MAY7,1919.

To allwknm'itmaycmwem:

Be it known that I, James F. GAMILLE, a citizen of the United States, residing at Fredericktown, in the county of Washmgton and Stateof Pennsylvama, have invented certain new and useful Improvements in Mine-Ventilating A pliances, of which the followin is a spec' cation.

This invention relates to pneumatic designal or alarm in the mine and at points or locatlons distant from the mine.

failure to or at various locations A still further object of the invention is to provide in a tunnel or mine shaft supplied with artificial ventilatingg air currents, devices which shall be operated by such currents and cease to operate simultaneously with the failure or-disorder of the air current producing means so as to signal such in and outside of a mine or tunnel.

.In the accompanying drawings forming part of this application Figure 1"i's a side view illustrating one form of the invention electrically connected for light and bell signaling, the dotted lines showing the air vane as indicating absence of air current in a mine or tunnel.

Fig. 2 is a top view of what is shown in Fig. 1.

Fig. 3 is a detail perspective view showin a modification of Figs. 1 and 2.

he same reference characters denote the same parts throughout the several views of the drawings.

In view of the fact that the purpose of the invention is to have the mine ventilating -or vane placed in such currents, I

device such as a blade the path of movement of have devised devices for mounting said vanes and for affording air currents operate a means for electrically connecting the mountings with signals such as an audible alarm and lights which may be in places remote post 12 Specification tr ea-amen. t te 1921 Application filed m 7, 1919. semi 10. 295,313.

from a mine or tunnel as well as located adjacent thereto, and which may have suitable switchboards.

In carrying out in invention, as illustrated especially in igs. 1 and 2 of the drawings, I use a single blade 1, having an arm 2 pivoted as at 3 for swinging movement in an artificially ventilated mine or tunnel. The pivot post or arbor 9 of the arm 2 is wired with a battery which is wired .with the ends of a contact guide 4.. The

arm 2 is operated by ventilating air currents through the mine striking the blade 1, which holds the arm at one end of the guide 4, so as to operate the safety signal light 5. When ventilating currents cease, the arm 2 is retractedb a coil spring 8 to the other end of the gui e 4 so as to operate the danger light 6 and the alarm signal 7. The arm 2 may have a weight 5 adjustable on a screw 10, to assist in dropping the arm to danger position. The spring 8 may be omitted and a weight and lever device substituted for dropping the arm. Said device comprises a screw stem 14 having a weight 13 adjustable thereon, a stationary having a right angle projection 11 upon which the stem 14 is pivoted as is also a lever 15 through which the stem extends, said lever 15 being connected with a bracket 15 attached to the arm 2, by a connecting link 10*. As long as the ventilating air currents maintain the arm blade in substantially horizontal position the said lever 15 and the link 10 are in extended position, but upon such current pressure ceasing, the weight 13 will retract the said lever and pull the arm to danger position.

It must be understood that the vane mountings should be so placed in a mine as to position the vane or vanes in the path of the. air ventilating currents; that the electric signals may be located in the mine as well as distant from the mine; that means Therefore I do not wish to confine myself in the above noted respects, nor to limit the invention in size, material and arrangement with respect to mounting the vanes and counterbalancing them, but reserve the right to make such changes and variations in the manufacture and practical application of the invention as may come within the scope of the appended claims.

Having thus described-my invention what I claim as new and desire to secure by Letters Patent is:

1. A device of the type described, including a vane, a pivotally supported counterbalanced member carrying said vane, 21 segmental guide for restricting the movement of said vane-carrying member, an electrical contact at each end of said segmental guide, and an electrical contact carried by said vane-carrying member to make contact with eithercontact of said segmental guide.

2. A device of the type described, including a vane, a pivotally mounted counterbalanced member carrying said vane, a guide member having a segmental slot for restricting the movement of said vane-carrying member, an electrical contact at each end of said segmental guide, and an electrical contact carried by said vane-carrying member to make contact with either contact of said segmental guide..

'3. A device of the type described, in-

cluding a vane, a pivotally mounted and adjustably counterbalanced member carrying said vane, a segmental guide for restricting the movement of said vane-carrying member, an electrical contact at each end of said segmental guide, and an electrical contact carried by said vane-carrying member to make contact with either contact of said segmental guide.

4. A device of the type described, in-

cluding a vane, a pivotally and resiliently mounted and counterbalanced member carrying said vane, a segmental guide-member for restricting the movement of said vanecarrying member, an electrical contact at each end of said segmental guide, and an electrical contact carried by said vane-carrying member to make contact with either contact of said segmental guide. i

5. A device of the type described, including a vane, a pivotally supported member carrying said vane, comprising an arm controlled by a resilient member, and hav-' ing applied laterally thereto a threaded member with a movable counterbalance thereon, a segmental guide for said arm, an electrical contact at each end of said segmental guide, and an electrical contact carried by said vane-carrying member to make contact with either contact of said segmental guide. In testimony whereof I afiix my signature in presence of two witnesses.
