end of the line.

The object of my invention is to provide certain improved devices hereinafter fully described and whereby this method of stored spring propulsion is carried into effective and efficient operation and also to provide for the ready adjustment of the power to the result to be produced.

In the accompanying drawings which illustrate a construction embodying my invention, Figure 1 is a side elevation of one end of "throughout the several views.

The hanger A usual in store service appa- 'ratus is suitably suspended from the ceiling and brace wires A A are attached to the lower end of the standard to assist in sup porting the apparatus at both ends of the way. Secured to the lower end of the standard A on the shaft D is a suitable casting B having a suitable hub O in which is mounted the shaft E shown in Figs. 2 and 3 and on this shaft is mounted at one side the bell crank lever E held on the shaft by the washer F and pin F. Extending outwardly from the upper end of the casting B is the boss D to which is secured the hollow arm B having a suitable continuous slot B in its upper side. Located within the arm B is a rodE to the outer end of which is secured the bracket G by the set screw G and between said bracket G and the outer end of the arm B is a suitable spring G to cushion the re- 'by cushions .0

turn of the carrier upon itsicontacting with the rubber propelling spring G on its return from the opposite end. This rubber spring.

is secured by knots G to the eyes Or on the ends of the bracket G and normally rests on the wire H in position to be engaged bythe incoming carrier.

H is a carrier of the usual construction having the box N adapted to be attached to and detached from the main body of the carrier (in the usual manner of store servicesystems) and said carrier is provided with a recess H in one end H and with said recess is adapted to engage the finger K on the lever J pivoted at K to the cross bracket C having two opposite'sleeves C free on the opposite rods 0 the outer ends of which rods O 4 ISAAC W. LITCHFIELD, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO LAMSON CONSOLIDATED are supported and held respectively by the collars O and pins O on the bracket O fixed" rod O bear at one end against the freesleeves O and at their opposite ends against the fixed sleeve C on the casting B. These" springs are for-the purpose of cushioning the impact of the carrier as it enters one end of the line and strikes the end of the lever J, the rebound of the sleeves 0 being relieved The inner ends of the forked spring K are secured in the opposite sides of the bracket O and extend forward and press down on the end H on opposite sides of the finger K and hold the carrier from swinging when the finger K is raised for the despatch ofthe carrier. p v

The end E of the link E is secured at E to the rod E as shown and the oppositeend of the link E is pivotally secured at B to the arm E of the bell crank lever E and said le ver is provided with a lower arm E to- Which is secured the operating handle E Located around the arm B and movable thereon is a trip L having anti-friction roller L at its lower end and adapted to be adjusted along the armE toengage any one ofthe holes L in the rod E and to be held fast to said rod by the set screw L The adjuste ment of trip L along the arm is to regulate the extent to which the carrier is propelled and the speed of the car willdepend on-the rod E prior to releasing the carrier and this distance can be varied by locking the trip in any one of the recesses L With the parts in the position shown in Fig. 1, the operator taking hold of the handle E pulls down the same which moves the bell crank lever and with it the link E moving outwardly the rod E in the arm B. The continued pulling on the handle E will bring the trip L over the end K of the lever J and as the friction roller L moves up the incline on the end K it will depress same and raise the finger K from engagement with the recess H allowing the carrier to be despatched by the stored inertia of the spring G as said spring is put under tension by the outward movement of the bracket G carried by the rod E and. this tension of the springG upon the upward movement of the finger K will despatch the car to the opposite end of the line. Upon the despatch of the carrier, the operator releases his hold upon the handle E when the spring E (Fig. 3) having one end bearing against the hub C and the opposite end against the under side of the arm E will move the bell crank lever E and the rod E back to their normal positions shown in Fig. 1. The return of the rod E is cushioned by the spring G By mounting the casting B on the shaft D, the arm B secured to the boss D can be tilted to any desired angle and held by means of the collar D pivoted at D to the supporting rod D which is common in store service apparatus, and is secured to the standard A by a suitable collar. This adjustment of the arm B to any desired angle for different heights of cashiers stations is advantageous and does not interfere with the operation or construction of said de vlce.

Fig. 4 illustrates a modified form of device for holding the car at the end of the line. 1) represents a hollow arm in which is mounted the rod 6 which is adapted to slide in a in anner similar to that described for the rod E in Figs. 1 and 2. Around this arm 5 is secured the bracket 0 provided with sleeves c to which are secured the rods 0 by suitable pins 0 The impact of the carrier as it e11- ters one end of the line and strikes the end of the lever is cushioned by the springs 0 the rebound of the sleeves 0 being relieved by the cushions c Collars c are mounted on the rods 0 and against said collars one end of the springs c? bear and are adapted to take up the blow of the carrier entering a station. From the collars c extend the lugs c which form a bearing for the shaft 7c of the lever j which at its outer end is provided with a lip is adapted to engage the recess h 011 one end h of the car which is adapted to travel on the way h; to the opposite end of the lever is secured the spring k and the opposite end of said spring is secured to the bracket 16 mounted on the lower side of one of the collars c and said spring normally holds the finger 7c in position to engage the car entering the station. l Vhen it is desired to propel a car, the operation is identical to that described for Fig. 1, and as the rod 0 moves outward, the roller Zon trip Z contacts the upper end k of the lever and pushing on the same forces the iinger 71: out of engagement with the recess 71 of the car when the car is propelled along the line. The rod 0 is provided with recesses Z for the adjustment of the trip Z as previously described for Figs. 1 and 2.

The following advantageous features are embodied in the device hereinbefore described: Avoiding the use of cord common in spring cash carriers. Stretching of the actuating spring from the fork end thus giving an auxiliary push to the ear. The toggle joint arrangement by means of which the power necessary to operate the device is equalized at every point of the actuating spring; that is to say, when the toggle oint arrangement is making speed at the expense of power, the actuating spring is at its weakest point and when the said joint arrangement is making power but little speed, the actuating spring is at its greatest tension. The method of adjusting the device so as to give more or less tension to the spring. The lightness of the parts to which the latch is pivoted so that there is little inertia to be overcome by the incoming car when it strikes this part. The offsetting of the upper 1ne1nber of the bell crank lever so that brace wires can be attache d to the standard at a very low point.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a cash or parcel carrier, a track or way, a carrier adapted to travel on said track or way, a spring adapted to propel said carrier along said track or way, sliding means for applying tension to said spring, and. a toggle jo1nt for equalizing the power to be applied to said sliding means to produce any degree of tension in said spring.
