CASH AND PARCEL. CARRIER.

SPECIFICATION forming part of Letters Patent No. 325,426, dated September 1, 1885.

(No model.)

f'o all whom it may concern:

Be it known that I, ROBERT- A. hIOGARTY, of Detroit, Vayne county, Michigan, have invented a new and useful Improvement in Cash and Parcel Carriers; and I hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, which forms a part of this specification.

The figure is a perspective drawing of my invention, showing the carriage employed by me, the method of holding it in position while a propelling force is accumulating, and the method of releasing the carriage and allowing the accumulated propelling force to be expended in moving the carriage forward along the way upon which it is adapted to travel.

My invention has for its object to furnish a simple and convenient engine or motor for imparting motion to a carriage adapted to travel on a way or track extending from one portion of a building to another, particularly when such carriage is used for transporting cash or parcels from that portion of a store occupied by the salesman to the cashicrs or book-keepers desk and returning the same from the *ashier or book-keeper to the sales man.

The way or track employed by me consists ofa strained wire, which is either horizontal or inclined. I prefer to use an inclined way, inasmuch as in that case onlya single propel ling'engine is necessary, as the carriage, having mounted an inclined way, in consequence of force imparted to it, will return by force of gravity when allowed to do so. My carriage is shown at A, and consists of a hanging car, a b, hanging from two or more wheels. Upon these wheels I place grooved rubbed tires, or manufacture the wheel, except the axle upon which it turns, entirely of rubber, and in this way overcome the noise usually accompany ing the passage of a hanging car upon a wire way. At either end of the carriage is a hook or detent adapted to catch upon appropriate hooks fixed near either end of the way, and

by the interlocking of the hook upon the end ot' the carriage with the corresponding hook near the end of the track the carriage is held from motion along the track until the interlocking of the hooks has been loosened. Upon the carriage is constructed a projection or horn (shown ate) rising above the plane of the track, and adapted to catch the cord G, hercinafter described, and retain said cord before it as the carriage moves from the position shown by the dotted lines to the position shown in full lines.

My propelling-engine is placed at or near one end of the wire way W', extending from one portion of the building to another. Upon the wall or other fixed portion of the building to which an end of the wire way is attached I affix standards M M, which project from the walla short distance, and at their outer extremity support an upright rod or standard, N N, the upper end of which is slotted, and has mounted in the slot two sheaves, or a dou ble sheave, E E. Through a perforation in the lower part of the standard N N I pass the wire track 7, attaching the end, after passing it through such aperture, to the wall of the building. Just below the aperture through which the wire XV passes I mount upon the standard N N a spring-catch, c, and a short distance above the wire way, upon the stand ard, I mount the U-shaped or compound arm V, the outer end of each branch of which (marked B D) carries a sheave or pulley. Over these sheaves I pass a cord,passing from above at H over the sheave at B, thence so it will lie loosely on the wire way, up over the sheave at D, and back to the point H. \Vhen the carriage is not present, this cord will lie loosely on the wire; but when the carriage is in the position shown at A the cord will have been caught under the horn c, and will assume the position shown in full lines. The two ends of this last-mentioned cord are broughttogether and attached to a spring, H, which may be either rubber or coiled wire. At the other end of the spring H, I attach two other cords, passing therefrom over E and E, uniting in a single cord after theyhave turned downward over E E. The united cord is continued downward to 0, where it is terminated by a.

ring or other suitable appliance to enable it to be grasped.

I E to 0.

From the spring-catch c,I pass still another cord, which is attached to that passing from The point of attachment is determined in the following way, to wit: After the wire track is mounted and the distance to be traversed by the carriage is determined, I find by experiment how much expansion of the spring H will be required to propel the carriage over the fixed distance, then with the carriage in the position shown at A, with the cord 0 passing around the born c, as shown in the drawing, I expand the spring H, by pulling downward upon the ring O,until the force stored in the expanded spring is sufficient to propel the carriage as far or as forcibly as may be desired. The cord X, having one end attached to the catch a at T, is then brought downward to the cord passing from E to O and fastened. In making this attachment it is desirable to make the angle between the two cords as small as possible. Upon drawing the ring 0 a short distance farther downward the expansion of the spring is increased; but the interlocked hooks to c are immediately disengaged and the contractile force of the spring, exerted through the cord H B O D H, immediately propelsthe carriage forward. At the end IV of the track a catch, K, made of spring metal,or having a leaf-spring beneath it, as shown, is fixed, which interlocks with the hook on the forward end of the carriage and prevents a return until released either by hand or by suitable mechanism. The arms V may be attached directly to the wall; but I prefer to attach them to the perpendicular rod or standard affixed to but held at a little distance from the-wall, as shown in the drawing. They are thus held firmly, and at the same time may be readily adjusted at any elevation or in any desired position.

horizontally by means of set-screws.

I do not claim herein a cash-carrying system wherein are combined a way, acarriage adapted to move on said way, and means for giving an impetus to said carriage, or such a system when such impelling device is stationary with relation to the carriage, or such asystem when such impelling device is a spring or spring mechanism; and, further, Ido not claim herein the employment in such a system of an impelling device at each end of the way, or a horizontal way, in combination with an impelling device at each end thereof, all such features being already included in an application for patent filed by me March 1, 1884.

Having thus described myinvention andits mode of operation, what I claim as novel, and desire to have secured to me by Letters Patent, 1s

1. In combination with a carriage adapted to travel on a way, aspring arrangednear one end of said way, means, substantially as described, of producing tension in said spring by drawing the same against the rear of said carriage, and a catch adapted to grasp said carriage and hold the same until the desired amount of tension has been produced in said spring to project the carriage to the opposite end of the way.

2. A cash carrier system consisting of a way, a carriage adapted to travel thereon by the force of a spring apparatus, substantially as described, connections therewith in reach of the salesman for compressing said spring, and a catch for holding said carriage against the propulsive force of said spring, and a cord or like connections within reach of the salesman for unclasping said catch,- substantially as shown and described.

3. In an engine for propelling a carriage uponaway, the combination of a cord passing from the spring of said engine across the path of the carriage,a spring attached to said cord, and a cord or like connection with said spring within reach of the operator, whereby the spring may be expanded by force applied to said cord, substantially as described.

at. In an engine for propelling a carriage upon a way, and in combination a spring brought into tension by expanding the same, a cord to enable one end of said spring to hold or press against said carriage, and a second cord attachment to the other end of said spring, passing over sheaves and brought downward to enable tension to be produced on said spring, substantially as and for the purposes described.

5. In a cash-carrying system, the combination of an inclined way, a carrier adapted to ROBERT A. MceARTY.
