STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 607,032, dated July 12, 1898.

Application filed May 12, 1896. Renewed December 7,1897, S ial No. 661,090. (N d l,)

To all whom it may concern.-

Be it known that 1, JOHN H. GOODFELLOW, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Store-Service Apparatus, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in that class of store-service apparatus in which a way is supported between stations and on which a carrier travels.

It relates more particularly to certain improvements in the mechanism for giving the carrier the impetus that propels it from one station to another.

The invention consists, primarily, of a wire extending from station to station substantially parallel with the way and connected at one end with a spring mechanism and provided at the other end with means for varying the tension of said spring mechanism, and thereby imparting an impetus to the carrier mounted on the way to propel the same.

The invention further consists in the novel construction, combination, and arrangement of parts, such as will be hereinafter more fully described,pointedout in the appended claims, and illustrated in the accompanying drawings.

In the accompanying drawings, in which similar letters and figures of reference designate corresponding parts, Figure 1 is a side elevation of a store-service apparatus embodying the invention. Fig. 2 is a similar view showing a modification of the same.

Referring to the drawings by letters and figures, l3 and B respectively designate the supporting-brackets, which may be of any construction suitable in the premises. Between these brackets the way S is stretched. In the foot-bracket 8, on the lower end of the bracket B, a pulley b is journaled in line with the Way. Over this pulley an elastic cord 6 passes and is secured at one end to the clamp; slide d, adj ustably mounted on the bracket 13. The other end of the cord is secured to the latch-body f, mounted onthe way S, so as to move freely thereon.

On the way S,'near its end connected with the bracket B, is mounted a second latchbody f moving freely thereon. To this body is secured an end of the elastic cord 10. The other end of this cord passes through the bracket-step 12 and is connected with the dog 13, mounted on the arm 14.. The dog is adjustable on the said arm and is held in position thereon by the rod 15, hinged tosaid dog at one end and pivoted at the other end to the sliding clamp 16, mounted on the bracket B. The clamp is provided with a set screw for securing it in its adjustments.

A wire 0*, running substantially parallel with the way S, connects the latch-bodies f and f. This wire is held taut by the elastic cords e and 10, respectively connected with the latch-bodiesfandf. The tension exerted by these elastic cords on the wire can be regulated. By means of the slide-clamp d the elastic cord 6 can be stretched to any desired extent, as can the elastic cord 10, by the adjustable dog 13. By regulating the stretch of these elastic cords the tension exerted on the wire r and the cords themselves can be varied to any desired extent.

A thimble tis mounted on the Way S, intermediate of its ends, and has an aperture formed therein through which the wire r passes and can freely move. This thimble serves to hold the wire in its proper position relatively to the way.

Pivoted to the under side of the latch-body f is a latch g. The free end of the latter is normally held in an elevated position by the spring g. Aweighted arm h is secured to the latch for a purpose that will be explained farther on. A latch g is also pivoted to the body f Its free or engaging end is normally held in an operative position by the Weighted arm h and the spring g A carrier H, provided with suitable wheels, is mounted on the way S. From opposite ends of the same catches i and 4?, respectively, project. The catch t' is adapted to engage with the latch g, and the catch t is adapted to engage with the latch g In the foot 8 of the bracket B a pulley Cb is journaled. Over this pulley a cord 1) passes and is attached at one end to the latch-bodyf. The other end of the cord is provided with a pull-handle T.

In the foot 12 of the bracket B a pulley a is j ournaled. A cord D passes over this pulley and is secured at one end to the latch-body f and has attached to its free end a pull-handle T.

The operation of the device is as follows: Assuming the carrier II to be in the position shown in Fig. 1 and it is desired to send it to the other end of the way, the operator pulls down on the cord D, and thereby draws back the latch-body f and also the carrier connected with the said body by means of the latch g and the catch 1; engaging. This moveinent of the latch-body f through the wire 4" stretches the elastic cord 10 through the intervening mechanism. The cord D is then released by the operator and the elastic cord-- 10 allowed to contract. The contraction of the cord 10 through the intervening mechanism gives a sudden impulse to the latchbody f. This movement of the latch-body causes the latch g to disengage from the catch '5. As the weighted arm his hinged to the latch-body, the momentum given to the latter will not be directly imparted to the said arm, and consequently it will hang back to a considerable extent, and thereby move the latch to release the same from the catch 2'. The impulse given to the carrier will cause it to travel to the opposite end of the way, where it will strike the latch-bodyf'. The force exerted by the carrier striking the latchbodyf' will be taken up by the elastic cord 6, connected with the wire 0". On striking the body f the latch will engage with the catch 4?, and thereby prevent the carrier from springing back. To send the carrier in the opposite direction, the operation is repeated through the cord D and'the intervening mechanism.

The construction shown in Fig. 2 is substantially the same as that shown in Fig. 1, except that there is only one propelling mechanism in the former. In this instance the way is inclined so that the carrier can travel in one direction bygravity. In this construction B and B respectively designate the supporting-brackets. In the bracket-foot 28 the pulley b is journaled and has passing over the same the elastic cord e The latter is secured at one end to the sliding clamp (Z mounted on the bracket Bl". The other end of the cord is attached to an end of the wire '11 supported substantially parallel with the way S A thimble is mounted on the way and has an aperture formed therein for the free passage of the said wire. Theother end of the wire 0' is connected with the operating-cord D passing over the pulley a journaled in the bracket'foot 120. The cord is provided with a buffer 20.

A spring-pressed latch 21 is pivoted to the bracket B for engaging with the carrier and holding the same. A handle 91 is provided for moving the latch torelease the carrier. A stop 30 is provided for receiving the carrier V at the lower end of the way.

To send the carrier up the incline, supposing it to be resting against the stop 30, the cord D is pulled and stretches the cord e \Vhen the cord is released, an impulse is given to the carrier that will carry it up the inclined way, where it will be caught by the latch 21 and held. The force exerted by the carrier striking against the catch will be taken up by the butter 20 on the operating-cord.

Having thus described my in'vention,what I claim, and desire to secure by Letters Patcut, is-

1. In a store-service apparatus, the combination of the brackets, a way supported between said brackets, a wire extending between said brackets and substantially parallel with said way, a spring mechanism connected with the bracket at one end of the wire, and means connected with the bracket at the other end of the wire for varying the tension of said spring, and a carrier mounted 011 said way and adapted to be moved by the action of said spring.
