STORE-SERVICE APPARATUS..

SPECIFICATION forming part of Letters Patent No. 502,277, dated August 1, 1893.

Application iiled March 3l., 1891.

Serial No. 387.088. (No model T all whom, t may concern..-

Be it known that I, JAMES M. BURNS, of Chicago, in the county of Cook and State of Illinois, 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.

My invention relates to improvements in cash and bundle carriers.

The object ot' my invention is to provide a means for the automatic disengagement of the carrier from the elevator track section when said section is in line with the main track.

Another object is to provide means for regulating the descent of the elevator from the upper track to the switch track, and also with a car on it when this car by its momentum unlocks the elevator from its engagement with the lower branch track and allows the elevator and car to descend to within reach of the salesman.

Another object is to provide means for arresting the carriers on the lowerbranch tracks when the track is opened by the elevator with a carrier descending to the salesman.'

Another object is to provide means for causing the disengagement of the elevator track section with the main track and allowing the movable section of said main track to return to its position after the carrier has left the elevator track section.

Another object is to provide means for causing the engagement of the elevator track section with the lower branch track to receive the returning carrier after the disengagement of the elevator track section with the main track.

Another object is to provide an improved connection between the basket and the body of the carrier.

Another object is to track support.

Another object of my invention is to connect the elevator rope to the elevator in such a manner that the weight of the basket and its load will not be thrown against the guide rods as the elevator ascends.

IVith these and other objects in view, my 5o invention consists of certain novel features of construction and arrangement of parts hereinafter described and pointed out in the claims.

provide an improved In the accompanying drawings which illustrate my invention: Figure l is a front elevation of my improved apparatus showing the elevator and carrier within reach of the salesman and showing in dotted lines the movable section ot' the main track out of its normal position and the elevator track section in con- 6o nection with the main track and inclined so as to start the carrier. Fig. 2 is an end elevation of the standard, elevator and carrier in their lowest positions.

5 and 17. Fig.19 is a detailed View taken on the line la ot Fig. 12, ,hereinafter described. Ico

Like letters of reference refer to like parts throughout the several views.

The main or forwarding track A is held in place by proper supports hereinafter described and has a movable section A pivoted 1o 5 by a pin A2 at one end to the upper contigusection D by pin D;

ous stationary portion of the track A, the free end of said section being provided with a loop A3 sliding on a vertical post A4 which extends upward from the arm A6 of the bracket A5 which is fastened to the main track A on each side of the movable section A and when said loop rests upon the bracket A5, the movable section is in line with the main track A.

A chain a is fastened to the movable section A at a point b and has a ring 6^ around rope d at the other end; sleeve c is attached to rope d and when the rope which is connected to the elevator B at one end, the other end extending to the operator is pulled by him; to raise the elevator the sleeve c catches the ring on the end of the chain a and raises the movable section A from its alignment with the main track A as shown in dotted lines in Fig I. The elevator B slides up and down on the guides B by means of hooked portions B3 and B4; the arm B5 is pivoted at B8 to the front of the elevator and has the rope d connected to it and when the rope d is pulled by the operator, the arm B5 swings to a horizontal position as shown in dotted lines in Fig. 2 thereby causing the strain of the hoisting apparatus to be exerted directly over the basket. By this means the elevator is prevented from binding on its guide rods. If the strain of hoisting the rope did not come over the center of the weight on the elevator, the weight would sag to one side and cause the elevator' to bind on its guides.

The carrier C consists of the body C and basket C2 which are connected by bolt C3 passing through the lower ends CA1 of the body of the carrier and through the upper ends C5 of plate C5; from each side of the basket a bail GS extends upwardly and then horizontally resting on the plate C5, then downwardly to the same side of the basket from which it started; a plate C7 bears upon the hails C8 and is secured to plate C by screws whereby the basket is held firmly and prevented from swinging.

To the arm C10 of the elevator is pivoted the the pin D2 of said section D moves in a slot in the keeper D3 which extends upward and is pivotally secured at DA to arm C9 so as to adjust itself to the vertical movement of pin D2 along the slot.

To the rear side of the elevator section D is arranged a horizontally sliding rod E. One end E at right angles projects through a slot Eiin the section D. The rod is suitably supported by bracket E3. A spring E4 bears against the arm E and against bracket E5.

To the rear of the section D and below the end of the rod E is secured the right angled extension F having an arm F for a purpose hereinafter set forth.

From the hollow standard B2 extends a supporting rod G to the return track H; a rod G extends from the rod G to supporting rod G2 which extends from return track H to branch track I.

From a plate G3 secured to rod G2 extends downwardly a curved projection G4, from the side, a right-angled projection G5 and from the top a rearwardly curved projection G6 for a purpose hereinafter set forth.

A steel dog G7 of irregular shape is pivotally secured to rod G and extends around projection G8 to slot I in branch I. rlhis rod normally projects through slot I and prevents carriers from passing that point when the elevator is being raised or lowered. The curved spring BG which is attached to elevator C at the hooked portion B5 comes in coutaet with dog G7 and when the elevatortrack section D is in alignment with the branch I, the portion B7 of the spring 35 bears against dog G7 and withdraws its point from extending through slot I in track l, thereby allowing` carriers to pass onto the elevator section D and to be automatically lowered to the salesman in a manner hereinafter described. A spring G9 tends to keep the point of dog G7 through slot I.

To the rear side of the continuation of the main track A below and parallel to the arm A6 of bracket A5 extends plate K; between the plate K and the arm AG slides a rod L which normally touches the projections J of the plate J owing to the spring L7. The rod L passes rearwardly through an opening' L* in the right-angled projection L3 which is attached to the rear side of track A and is pivotally secured to the lever L by pin L2; said lever L moves in a slot L" in the track A and is pivotally secured to the projection L3 by pin L5. As the elevator and its track section ascend, the cross arm F comes in contact with the beveled edge of the rod L and forces it back sufticiently to allow the cross arm to pass beyond it; the spring L7 drawing the rod L beneath the arm F thereby holding the elevator section in alignment with the track A. As the carrier starts from the elevator track section, as shown in Fig. l, it comes in con tact with the lever L and forces it inward so as to allow the passage of the carrier. This movement of the lever L draws the rod L rearwardly to sufficient distance to allow the pawl L8 pivoted at L9 to drop into a cavity L10 in said rod and holds it in that position against the tension of the spring L7. As the elevator and its track section descend the pivoted section A lowers lo its normal position and theloop A5 falls on the free end of the pawl and disengages it from the rod L, thereby allowing said rod to regain its normal position owing' to the tension of the spring L7.

The arm M is mounted inthe elevator frame and extends through a slot in the elevated track section D. A spring M tends to project the arm M through the slot; the end of the arm is beveled so as to cause the arm M to be forced inward by the body of the carrier when said carrier is passing to be thrown out by tension of spring M when the carrier has passed said arm, the carrier then being` held between Eand arm M. lVh'en the carrier is in this position the rod E is drawn in- IOC IIO

ward so as to allow the elevator track section to pass the switch track I, as otherwise the said rod would come in contact with the bottom of rod G2 and prevent the upward movement of the elevator. The spring Ff around the rod E is not under sufficient tension to give a start to the carrier when the elevator reaches its upper position. The object of said spring is to act as a buffer.

The rope d between the pulleys d d2 has resting upon it the pulley d3 attached to the ceiling by a spring. The rope (f4 extends downwardly from said pulley d0 to the crank arm N of the rod N2 mounted in brackets N. At the end of the rod farthest from the arm N, a sleeve N4 is loosely mounted on the rod; said sleeve has a projection N7 extending into the slot A10 of the track A; a spring N bearing against the sleeve N1 and bracket N. A cam N0 is attached to the end of rod N2 and as said rod is rocked,owing to the pull on the arm N from the rope d4 as the rope d is pulled by the operator, the said cam comes in contact with the arm N5 of the bracket N and throws the rod toward track and the projection NT through the slot A10; the carriers coming along said track A are stopped by projection N7 and the impetus of the carrier is taken up by the spring N3 thereby avoiding jar. The end of the red N2 at which the cam is attached is in a slot in the bracket N so as to permit endwise movement of the rod and sleeve attached thereto through the slot A10 to the track. The operators rope d passes over pulleys d and cl2 and is attached t-o the arm B5 of the elevator frame. The counterbalance rope c is attached to the elevator frame at e and passes upward and over pulley e2 to the governor and then over pulley e0 and down the hollow standard B2 to the weight c4.

The governor O which regulates the descent of the elevator frame and carrier is shown in Figs. 13 to 16. This governor is provided with governor disk O mounted on a governor shaft P provided at its lower end with guide bars P for the governor arms P2 supporting the governor weights P3 which are spread apart when the shaft P is rotated to the limit allowed by guides P. Farther up on the shaft the collar Pt1 is secured and to said collar the governor arms P2 are pivoted by pins P5. A curved extension P0 of the arms rests lightly against the fiat springs PT secured to bottom of stationary plate PS. A washer P10 of leather or suitable material is placed between plate P8 and plate P" to cause friction. A ratchet wheel O2 is secured to shaft P and the teeth of the ratchetwheel are engaged by a pawl O3 pivotally secured to disk O. A spring O5 tends to keep the pawl in contact with the teeth. A collar is placed between the ratchet and the upper plate O0. A washer is placed on the plate O0 around shaft P and a pin C)7 passes through an eye in shaft P and holds the parts together. Screws O0 along the inside of fianges O10 of plate OG secure said plate and plate P0 securely together. As the operator pulls on the rope (l, the elevator B rises along the standards B. The rope e is attached to the elevator at e at one end and at the other end to the weight cA1 in the hollow elevator standard B2. As the elevator rises, the weight c4 takes up the slack of the rope e, the weight falling down th rou gh the said standard B2. The rope passing around the disk O to the weight c'1 causes said disk to revolve freely; the pawl O3 is held by spring O5 in contact with the teeth of the ratchet O2 fixed to and moving with the shaft P. As the elevator with the basket on it descends, the disk O is revolved by the rope c; this movement of the disk causes the shaft P to revolve and spread the governor arms and weight outwardly, and throws the upper ends P0 against springs PT which causes the plate PS to press the washer P10 which comes in contact with the stationary plate P0 to cause sufficient friction to hold the plates in contact. By these means an easy and regular movement of the disk O is produced as the basket with its carrier is falling to within reach of the salesman.

The switch for conveying the carriers to their respective stations is shown in plan View Fig. 1l; this switch is similar in construction and operation to that shown and described in Letters Patent granted James Burns November l5, 1887, No. 373,172. As each carrier reaches its proper station, the flange R comes in contact with the inclined piece R and its momentum is sufficient to cause the flange R to slide down along the inclined piece and as the end of said piece R which is farthest from the central station is closer to the track than the other end, the flange on the carrier causes the free end of the pivoted section Q of the track to be crowded over to the switch track, since the piece R is fixed and the pivoted section Q, of the track is movable. Then the flange R crowds the pivoted section of the track over to unite its free end with the end of the switch track, the wheels of the carrier, of course, follow and by the time they have reached the end of the switch, it and the free end of the pivoted section of the track coincide so that the carrier rolls on to and along the said switch track. rPhe instant that the flange R has passed the inclined piece R', the wheels have passed entirely on to the switch so that the pivoted section of the track can be and is drawn back by the spring R2 into its place of connection with the return track H. The next carrier intended for that particular station repeats the operation above described, while those intended for stations farther on, pass through without the flange R coming in contact with and rubbing against the inclined piece R. lf there be many stations in the main return track, the inclined piece R may be located at different heights as at different distances from the track. This will permit a carrier to be switched oi'f at one station while the next carrier with its flange higher up or lower down on TOO j were all the flanges and all the carrier plate, although of no greater width than the one which has been just switched off would carry its flange over or under the inclined piece which has effected the switching of the preceding' carrier and roll on untilaswitch was reached, where the inclined piece R was not only the proper distance from the track but also in the right plane to be struck by the flange R. In this way and by these means any number of switches can be located on the return track and any number of carriers employed without unduly increasing the width of the flange R as would be the case the inclined pieces R arranged in the same plane. A bracket T is attached to the side of the return track and eX- tends upwardly and over said track H and is for the purpose of straightening up the car-` rier before it reaches the switch.

The movable section A of the main track A is composed of two parts AT and AS united by a pivot joint A9, the pivot being below the center of the two posts, so that when the section A is drawn from its normal position by chain ct, it will assist in holding said section in this upper position shown in dotted lines of Fig. 1.

S S represent two parallel posts in a plane at right angles to the line of the tracks. They may consist of any suitable tubing or they may be formed solid and be made either of wood or metal. Track-supporting brackets S2 are provided with three sockets sufficientlylarge to admit the posts S S the parts of the bracket S2 in which the sockets are formed are connected by curved braces S3 which prevent the spreading of the socket pieces and when the posts S i" are slid therein or the brackets are slid on the posts, they lock the postsat a certain distance apart and prevent them from tilting in the direction in which the weight of the track and its load would tilt them. I have arranged the brackets on opposite sides of the posts so as to balance the strain upon the posts by forwarding and returning carriers on opposite sides. The arms S4 S5 lead from the socket heads S6 and converge in and unite at points S7 SS to which the forwarding trackA and return track I-I are respectively connected.

A downwardly extending rod U is attached to cross piece U and as the elevator is raised the lower end of said rod U comes in contact with the beveled end of the rod M and forces said rod M inward against spring h so as to allow the carrier to start upon the incline of elevator track section D to the way A. Suppose that the carrier and its baskets to be in the position shown in Fig. 1. The body of the carrier being held between the arm. E and arm M of the elevator track section D as the operator pulls on the rope d, the arm B5 of the elevator swings to a horizontal position and the elevator with its track section and carrier begins to ascend. As the rod E of the elevator section D is thrown inward, it passes the rod G2 and the right angled arm F passes bythe right angled projection G5 and the downward projection G4'. The projection G5 is for the purpose of holding the elevator track section to alignment with the switch track I in case it should be horizontally displaced and the projection G4 for moving said elevator section rearwardly in case it should be not in alignment as it reaches the switch track I by the cross arm F coming in contact with said projections. The elevator' continues its ascent and the cross arm F of the ri gilt-angled projection F comes in contact with the under side of the projection J having thrown the rod L rearwardly by these means the elevator track section and the forwarding track are held in alignment as hereinafterdescribed. This end of the track section D is thusheld in position and the continued pull on the rope (Z causes the elevator track section D to swing on pivot D and causes its other end to lift vertically in the slot of the upright projection D3, thus giving an incline to said section D, whereby the carrier is started on its way as the depending rod Uis moved in the arm M and the carrier is released; the button c in the meantime having come in contact with the ring on chain a and lifted said chain and pivoted track section A to the upright position shown in Fig. l. The carrier having started upon its way, the operator loosens his hold on the rope d and the elevator with its track section D begins to descend and the pivoted track section A assumes its normal position between the two ends of the track A; the loop A3 sliding down the rod A.'1 has fallen on the inward end of the pawl L8 and swings its free end from the engagement with the cavity in the lever L, which lever owing to the spring L7, returns to its normal position as shown in Fig. 7. As the elevator and its track section reach the switch track I, the end of the rod falls on the end of the rod G2 and holds the elevator sec tion in alignment with said switch track I the upward curved projection GS serving to throw the said elevator section to its proper vertical alignment with said switch track bythe said rod E sliding down said upward projection. The rod E stands out sulliciently free to come in contact with said rod G2 as the carrier is not pressing against the arm E2 of said rod as shown in Fig. l. As the carrier returns upon the track H, as stated by the bracket T, it operates a switch in a manner hereinafter described and passes to the switch track I and then to the elevator track section D, pushing in the arm M and coming in contact with the arm E2 of the rod E and springE4, taking up the impetus of the carrier and avoiding jar. As soon as the body of the carrier passes the arm M, said arm, by reason of its spring M, is thrown downward and holds the carrier between it and the arm E. This inward movement of the rod E caused by the carrier pushing the arm E along the side E2, withdraws the end of the rod E from contact with the rod G2 and the elevator with the carrieraud its baskets upon IOO IIO

the elevator track section begins to descend in an easy and regular manner owing to the connection of said elevator with the governor heretofore described.

Having thus ascertained and described the nature of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

l. In a store service apparatus a forwarding track having a moving section, an elevator carrying an elevator track section upon which the carrier is supported, the spring controlled rods E and M attached to said elevator track section, said carrier being held on the elevator track section by the said spring-controlled rods E and M, in combination with a downwardly extending rod U adapted to come in contact with the rod M so as to release the carrier when the said elevator track section is in alignment with the forwarding track, substantially as set forth.
