STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 496,147, dated April 25, 1893.

I Application filed April 2 3, 1892. Serial No. 430,385. (No model.)

To all whom it may concern:

Be it known that I, THOMAS E. BARROW, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Store- Service Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in store service apparatus, in which a stationary track wire is used for carrying the car and a propelling wire to propel the car from station to station. And the objects of my invention are first, to obviate the necessity of lowering the package basket at the salesmans station; second, to so construct a line that the car and basket can be sent to the wrapping counter up an incline line or track, or to so construct the same that the car and basket can be'propelled up an incline to a sufficient height to raise the same on a level with the wrapping counter, then pass over a level line to the said counter; third, to so construct the car that there will be no jar or noise when entering the stations, either when going up the grade or down the same; fourth, to construct the car with a brake or lock to operate only when passing down grade to check the velocity of the same; fifth, to so construct the foot, forming part of the hanger or support, so that it can be adjusted to conform to any grade required. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a grade line complete, showing both stations, package car and wrapping counter. Fig. 2 is a portion of a car, one carrier wheel and propelling wheel or pulley, and also showing the device for locking the wheel or Wheels when passing down grade. Fig. 3 is a top sectional view of same taken in line m-a*. Fig. 4 is a longitudinal sectional view and perspective view of a sliding clip, showing the track wire passing through the upper tube and adapted to slide upon the same, and also showing the inner ends of the propelling wires secured rigidly in the lower tube. Fig. 5 is a side elevation of a level and grade line combined, showing the general construction of the same. Fig. 6 is .an enlarged view of a portion of the car, track wire and propelling wires, bridge and support; also locking device for the carrier wheel or wheels constructed for a combination level and grade line. Fig. 7 isa transverse view of the same. Fig.8 is a front sec tion view of a portion of the foot and support, showing the adjusting device; and Fig. 9 is a transverse sectional view of same.

Similar letters refer to similar partsthroughout the several views.

In the accompanying drawings,-A indicates hangers or supports; B a sleeve or socket which is provided with female threads in the upper end and bifurcated at the lower end to receive the foot C which is pivoted therein by the bolt D, the said foot 0 being provided at its upper end with alug E and upwardlyprojecting arm F, the object of this construction being for the purpose of adjusting the foot to the incline required for a grade line, and this is accomplished by operating upon the set screw G. It will be readily seen that by turning the set screw G in either direction, the foot is adjusted to conform to the grade of the line. This construction is fully illustrated in the enlarged views Figs. 8 and 9.

B B represent operating levers which are pivoted in the feet 0, and to the outer end of which the propelling wires are attached.

In this application in place of having the wires extend from station to station through the tubular clip as shown in my application filed December 10, 1892, Serial No. 414,632, and in another application filed by me March 9, 1892, Serial No.424,286, I construct onlythe stationary track wire I of a single wire and extend it entirely through the clip from station to station while the propelling wire J is made in two parts, one part extending from a station and secured by its other end in the clip and the other part extending from the other station and similarly secured in the clip. The sleeve or clip H is adapted to slide upon the track wire I in the place of the propelling wire sliding through the clip as shown in the ICO above mentioned applications. My object in this construction is of vital importance, as it does away with the wear upon the propelling wire. At the same time it allows the operator to draw back from each end of the line and allow all the spread required to propel a car up anyincline.

K indicates a package car, which is composed of a frame L provided with carrier wheels M and propelling wheels or pulleys N journaled in said frame.

O are lugs or eyes which form part of the said frame and in which is placed the rod P to which is attached the basket bail Q supporting the basket R. The said rod has a longitudinal sliding movement in the eyes 0 when the car strikes the stop T'at each station.

S indicates coil springs which are placed upon each end of the rod P, the object of the said springs being to retain the car in the center of the basket, and also to form a spring cushion when the car K strikes the shoulder T, forming part of the rubber catch U. This construction I have fully illustrated in Fig. 1.

Fig. 2 illustrates a brake or locking device Z which I use on all steep grade lines and which is very essential to check the velocity of the car when passing down a grade.

M indicates the carrier wheels which sup port the car and basket upon the track. The hub on one side of the wheel is provided with a toothed pinion V, and a lever W is "pivoted inside of the car frame, the said lever being provided at its outer end with a segmental internally toothed portion X which is adapted to mesh with the teeth in the pinion V, in such a manner that when the car is passing up the grade, the rotation of the wheel M throws the lever W out of action with the teeth of the pinion, allowing a free motion to the wheel when passing up the grade, and that as soon as the car starts down the grade the motion of the wheel is reversed, and the teeth in the lever are caused to mesh with the teeth of the pinion and lock the wheel, the friction of the wheel, sliding upon the track wire, retarding the motion and checking the car.

This construction I have fully illustrated in Figs. 2 and 3.

Fig. 5 is a side elevation of a horizontal and grade line combined. The only difference between this line and the line shown in Fig. 1 is that the grade A only extends a short distance along the line from the out station B, the greater portion of the distance between the stations, the car traveling upon a level line C to the home station D. My object in this construction is to raise the car to the level of the wrapping counter E in as short a distance as possible so that it will be out of the way and high enough to pass all obstructions; also to obviate the necessity of lowering the basket at the out station; and a further object is to lower the car and basket by a portion of the line being on a grade so that when the car is at rest at the out station thebasket will be just high enough for the operator to place in or take out the goods without detaching the basket from the car.

By means of a propelling wire F and by placing a hanger or support at a proper distance from the out station E, I am enabled to propel a car up an incline onto a level line with sufficient force to send it to the home station. The said hanger or support is provided at its lower end with a bracket 11 having a tubular projection I which is secured to or forms part of the bracket 11', the track wire A passing through the upper tube and extending from station to station, and the propelling wires F and K extending from the stations to the bracket H and secured rigidly to the same, or they may extend through the lower tube and extend from station to sta-..

tion, but only allowing a wedge to extend from the stations to the bracket. The said bracket holds the track wire and propelling wires on a level or nearly so with the home station. This construction is fully illustrated in Figs. 5, 6 and 7. When the bracket G is employed, the car will be open on one side (see Fig. 7) to allow the same to pass by the bracket 11, and a brake or look as illustrated in Figs. 5 and 6 is employed. This lock is provided with an upwardly projecting arm M and in the place of the lever having a free movement upon the pivot N itis constructed so as to have friction upon the pivot bolt N, the object of the friction on the lever being to hold the same in any position in or out of mesh with the pinion V. When the car is passing up the grade A, the rotation of the carrier wheel M works the teeth in the lever out of gear with the pinion, allowing the car to pass freely up the grade and along the level line to the home station, when the car is returned to the out station B. The lock does not operate until the car is passing over the bracket H. The hanger or support is provided with a sleeve having a projecting arm Q, against which the lever M comes in contact and forces the segmental shaped toothed portion of the lever into mesh with the pinion V, looking the carrier wheel M. I
