HARRY E. GOLDEN, 0F DUNBAR, PENNSYLVANIA.

INDICATOR.

To all whom it may concern:

Be it known that I, HARRY E. GOLDEN, a citizen of the United States of America, residing at Dunbar, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Indicators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a closed register ing indicator, for the hoisting engines of mine shafts, slips, wells and similar subways.

The primary object of my invention is the provision of positive and reliable means in connection with a hoisting cable for quickly determining the location of a trip or elevator in a shaft or flat leading therefrom.

Another object of my invention is to provide an alarm in connection with a hoisting engine for producing an audible signal previous to a trip reaching its destination, whereby the engineer or operator of the hoisting engine can give the engine his immediate attention.

A further object of my invention is to provide a simple, durable and inexpensive indicator for designating the distance a trip travels in a shaft and then the distance traveled by the trip in a flat.

Vith the above and other objects in view which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently described and claimed.

Referring to the drawings :Figure 1 is a front elevation of my indicator with the dial thereof broken away to show a portion of the interior mechanism, and Fig. 2 is a vertical sectional view of the same.

In the accompanying drawings, 1 designates a cylindrical casing having a closed dial 2 which is held upon the casing by a rim 3 threaded thereon. Extending vertically through the center of the casing is a support 4 provided with brackets 5 for supporting a plate 6.

Journaled in the support 4: and the plate 6 is a shaft 7 extending through the rear wall of the casing 1. The protruding end of the shaft 7 is adapted to be connected to the driven shaft 7 of the hoisting engine by meshing gear wheels 8. Mounted upon the contracted end 9 of the shaft 7 is a long Specification of Letters Patent.

hand 10, the purpose of which will presently appear.

Mounted upon the shaft 7 adjacent to the support 4 is a small gear wheel 11 meshing with a large gear wheel 12 mounted upon a revoluble shaft 13 journaled in the support a and the plate 6. Mounted upon the shaft 13 is a small pinion 1A meshing with a large gear wheel 15, mounted upon a sleeve 16, revolubly mounted upon the shaft 7 between the small gear wheel 11 and the contracted end 9 of said shaft. The forward end of the sleeve is provided with a short hand 17.

Secured to the sleeve 16 in front of the plate 6 is a disk 18 having a plurality of cireumfercntially arranged openings 19 adapted to receive a plug 20. The plug 20 is adapted to impinge a pivoted pawl 21, carried by the plate (5, and this pivoted pawl is adapted to strike a resilient arm 22 and move said arm into engagement with a contact 23, carried by the plate 6 and insulated therefrom as clearly shown in Fig. 2. The resilient arm 22 is connected to a wire 24, while the contact a3 is connected to the wire These wires are adapted to connect with an electric bell 26 and a suitable source of electrical energy, as a battery 27, said bell and said source of electrical energy being connected by a wire 26 Upon the dial are circumferentially arranged numerals from 1 to 16 and the hand 10 is adapted to make one revolution while the hand 17 is moving from the nume al 1 to the numeral 2.

In order that the operation of my invention can be fully understood, the indicator will. be considered in connection with a slope of one thousand feet in length, and a sulficient gearing is used to cause the long or fast moving hand 10 to make sixteen revolutions, while the trip or elevator is traveling a thousand feet, and the short or slow moving hand 1'? making one revolution in the same distance. This movement of the hands would be the same irrespective of the distance of the slope. It is therefore apparent that when the long or fast moving hand makes one revolution that the trip or elevator has traveled 62% feet, and during this movement the short or slow moving hand 17 is moved to figure 1 on the dial. .Dividing 62%} feet by 16 indicates the distance the trip or elevator travels while the long or fast moving hand 10 moves from one figure on the dial to the next figure. Such calculations in connection with the indicator allows the engineer to easily ascertain the location of the trip or elevator in the slope. For instance, if the trip or elevator was derailed, the engineer with a few seconds thought could tell the exact location of the trip or elevator. The alarm is principally used to give a signal when the trip or elevator is nearing the tipple or top landing, the alarm being sounded approximately 100 feet from the top landing so that the engineer can get the engine under control. The alarm can also be used for indicating places throughout the slope where the speed of the elevator or trip is to be reduced, as when passing through automatic trap doors and over bad sections of track.

Vfhile in the drawings forming a part oi this application there is illustrated the preterred embodiments of my invention, I would have it understood that the detail construction can be varied or changed as to shape, proportion and manner of assemblage sleeve and its hand at a lower speed than said first shaft, a disk on the sleeve, a pin on the dish, a stationary pawl actuated by the pin, a contact arm actuated by the pawl, a tixed contact engagcable by the contact arm, wires connected with the contact arm and the fixed contact and an alarm connected to the wires.

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