SPECIFCATION forming pari'. o Letters Patent No. 325,436, date-d September 1, 1885.

Application tiled April 25, 1885. (No model.)

To aZZ when?, it may concern: Be it known that I, SELDEN G. NORTH, a citizen of the United States, residing in the city and county of Philadelphia, in the State fof Pennsylvania, have invented a new and `fnseful Improvement in Store-Service Apparatus, of which the following is a specitieation.

Myinvention relates in general to that class of store service apparatus in which the traveling carrier is a basket or other goods receiver suspended from the depending arm or hanger ot a one or two wheeled truck, the wheel or wheels of which travel upon an elevated in :f clined trark composed of al single rail.

My invention' relates specifically to the switch or movable rails of tracks of the above class, and its object is the construction of a switch-rail which, in the ordinary set of the to parts, is closed or in alignment with the adjoining sections of the main track, but which is adapted to be by given carriers caused t automatically operate and to be thrown into conjunction with a branch track when it is desired to switch said carriers to said branch track, the carriers employed being provided, as to their depending arms or hangers, with laterally-extending trips, lugs, or projections, which arc differently disposed upon the 3o hangers of different carriers, so as to vary in height thereon, and which according to their vertical sct are adapted in the travel of the carriers to encounter trigger devices connected with or adapted to operate upon mech- 3 5 anism for permitting said extremity to gravitate in the direction of the desired movement of the switch-rail.

Apparatus conveniently embodying a good form of my invention is represented in the 4o accompanying drawings and described in this speciiication, the particular subjectmatter claimed as novel being hereinafter definitely specified.

In the drawings, Figure l is a front perspective view ot' a preferred form of my dcvice, the parts being represented in the positions which they occupy when the. switch-rail is in alignment with the adjoining sections of the main track, the continuation of the main 5o track, however, being, for clearer illustration,

removed. F ig. 2 is a front elevational view of l the paris depicted in Fig. l, representing,

however, an advancing carrier in the act of tripping the opening-trigger, so as to cause the lifting ofthe free extremity ot the switchrail to place said rail in position to gravitate into alignment with the branch track, and thereby to transfer said carrier to the branch track. Fig. 3 is an elevational view ot' the parts depicted in Fig. 2, representing, how- 6o ever, the carrier, which has been transferred by the opening ofthe switch to the branch track, in the act of tripping the closing-trigger so as to occasion the lifting of the free eX- tremity of the switch-rail to place said rail in 65 position to gravitatc into alignment with the continuation of the main track, and thereby to close the switch. In both Figs. 2and3 the continnation of the main track is, for clearer illustration, removed. Fig. 4 is a top plan view of 7o the entire device, the switch being open and the switch-rail in alignment with thebranch track. Fig. 5 is a similar View of the same parts, the switch being closed and the switch-rail in alignment with the continuation of the main track. Fig. 6 is a rear eleva-tion ot the apparatus represented in Fig. 5. Fig. 7 is a perspective detail of the opening-trigger removed from its housing. Figs. 8 and 9 are transverse sectional elevational details in the 8o plane of the dotted line .fr x of Figs. et and 5, Fig. S representing the position which the parts bisected occupy in Fig. 4, and Fig. 9 representing the positions which said parts occupy in Fig. 5. Sight is taken in the direction of the arrows in said Figs. et and 5. Fig. 10 is a vertical longitudinal sectional clevation through the compound pivot of the switch-rail on the line y/ y of Fig. l1. Fig. ll is a tcp plan view of the same. Fig. 12 is a 9o view in perspective of the pivot removed from its framing-plate andthe switclrrail. Fig. 13 is a transverse elevation ofthe swinging rollerplane and the roller lwhich is applied to the switch-rail, the view being intended to illustrate two positions of the parts. Fig. 14 is a fragmentary perspective detail of a convenient construction for maintaining the free eX- tremity of the switch-rail in close relationship with the continuation of the main track. ico

Similar letters of reference indicate corresponding parts.

In the drawings that portion of the main track which is in permanent conjunction with the hingedor pivoted extremity of the switch-A rail is designated A, while that continuation of the main track which is adapted, when the switch-rail is in its normal position, as shown 1n Fig. 5, to be in conjunction `with the free extremity 4of said switch-rail,is designated AX.

B is that portion or 'beginning extremity of a branch-track which is adapted,when the free extremity of the switch-rail is allowed to gravitate from its normal set, .to be in con- `junction with said extremity, and which,when' in such conjunction, is connected with the main track A by said switch-rail, as shown in Fig. 4.

a vis a preferably horizontally disposed framing-plate or housing with which the main track A and branch track B are connected, and whichis connected by a bridge or forked suspender, (LX, wit-ha supplemental yframingplate, c2, to which latter is connected the con'- inuation of the' maintra'ck AX, the said main track, continuation thereof, and branch track being in such manner connected in permanent relationship, and adapted conveniently' byy like, with the framing-plate a in such manner4 that the free end ot' said switch-rail is capable of havingimpartcd toit both an up and down movement in a vcrticalor practically vertical plane, and also of itselftaking on an in and out movement w1th respect, respectively, to the continuation of the main track AX and the branch track B in planes slightly inclined from the horizontal. As a convenient means of forming thc compound pivot, I provide the inner or pivoted extremity of the said switchrail with a laterally-extending heel or hub, c, Figs. 10 and 11, provided with a slot, c', running parallel with the rail itself', and mount the said hub upon a stud, c2, swiveled in the framing-plate a, and provided with a head, c, which is of breadth sufficient to fill the slot c in the heel of the switch-rail, and I then apply a horizontal pivot-pin, ct, which passes through the heel or hub of the rail,1and also through the head of the swiveled stud, as a refercnceto Figs. l0, 1l, and l2 will make clear.

By the above means, as will be readily nnderstood, the free extremity ot' the switch-rail is capable of a vertical movement up and down upon the horizontal pivot-pin c4 as an axis, whileitis also capable of an in and out movenient with respect to the swiveled stud c'l-as an axis, without regard to the vertical posi tion of the free extremity of said rail.

The framing-plate a, as a reference to Figs. 1, 4, and 5 will indicate, is so shaped that ample room is provided for the lateral gravi- NV h en the free end in alignment either with the continuation AX ot' the'main tracker with'the branch track B.

4tative movement of the switch-rail to place its The inner side of the said switch-rail, near its free extremity,`is provided'with a frictionroller, d, slide, or other traveling bearing,A

which is conveniently mounted, preferably both for free rotationand longitudinal or end for end travel, upon a'horizontal axle, d', contained ina housing, D, applied to said switchrail. The outer or free extremity of theswitchrail is also conveniently provided4 with an in'- -clined face, c5, which is formed by beveling tinnation of the main track AX- which is l-adapted to be aligned'withthe fre`e` extremity of the switch-rail when ,the switch isclosed, is also providedwith an oppositely-in'clined face, afand with a seat, at, abov'esaid face', which latter is adapted -to receive the overhanging shoulder'c6 of the switch-rail las shown in Fig. 14, the object of the construction be- -ing simply to afford certain 'engagement 'and stoppage for'the 'free "extremity 'of the4 switchrail when the latter gravitates'ont to alignment with the'conti'nuation of the main track. in whichlatter position the inclined faces c5 and c3 register and the'overhanging shoulder c6 rests within the seat cr. `When the switchrail gravitates into alignment with the branch track, it encounters 'and' is4 stopped by a shoulder, aor other strop in propinq'uit'y to 'said branch track.

Eis a sw-ingingtrigger, which I term the Aopeningtr'iggcr,7 pivoted tothe framingplate a' in' propinqnity to and in advance of the pi'voted end of the switch-rail. AThis trig-v ger is represented in perspective in Fig. 7, is applied to t'he main track, and is conveniently formed as a swinging stirrup provided with a IIO depending trigger-lug, e, which is adapted to be encountered by the hangertrip'on given carriers, and with a horizontal forwardly-extended trigger-arm, eX. The trigger is represented in Figs. l, 2, 4t, 5, and 6 as hung upon a horizontal pivot, e2, and its normal set is such that the trigger-arm e occupies ahorizontal position, while the triggeritself and its depending lug e are vertical. The application of the trigger is also preferably such that it can only be swung in one direction, orin thatv represented by the arrows in Figs. 1 and 6 and by the dotted lines in Fig. 2.

F is what I for convenience term a rollerJ plane, the same being` a movable plate, plane, carrying surface, or track, so to speak, upon which rests and is adapted to gravita'te, ride, or run the roller attached to the free extremi-A ty of the switch-rail. This swinging plane is adapted to be inclined either toward o'r away from the switch-rail, and is conveniently suspendedv upon arms f, 'conveniently pivotedy atA their upper extremities upon the plane-shaft G, which is shown secured in standards g,

erected from the frame-plate at the sides of a recess, a, formed in the plate, in which recess the roller-plane is adapted Ato move or swing.-

The space between the arms f f is sufficient for the entrance of the roller-housing on the switch-rail, Aas `shown in Figs. 4, 8, and 9. The arms f f of the roller-plate Fare provided with rearwardly-extending cranksfxfx.

II is a connecting-lever, being a-lever of the first order pivoted at h abovethe frame-plate a, and herein termed the opening-levi-irl7 The front extremity/.of this leveris conventiently "connected with that crank f* of the rollerplane which is adjacent to it, conveniently by being passed somewhat loosely thrueh a 1101 in, the free extremity .of `said. crank, while the rear extremity of said con` nectinglever is adapted .to overhang and rest upon the trigger-arm eX of the opening-,trigger E. i

I is what I term the closingtriggen77 it, being a swinging trigger pivoted to that porn tion of theframingplate a to which the branch. track B is. connected. Thesaid trigger is ap-d pliedlto said branch track, is provided with a depending trigger-lug, t, which in the normal set of the trigger is vertical, and 4is also provided with a forwardly-extending triggernose, ix. The set of theLclosing-trigger with respect to the horizontal pivot il upon which it is suspended, is preferably snchthat the trigger is only capable of a swinging move ment in the direction of the arrow in Fig. 6, or into'the position represented in Fig. 3.

J is a connecting-lever, being a lever of the bell-crank order, herein termed the fclosinglever,77 which is adapted tohave movement about a horizontal pivot, j, conveniently mounted upon the framing-plate a. The lower arm of this closing-lever is,ras shown in Figs. 3 and 46, provided A.with a lcurved surface, jx, against which the trigger-nose z'f of the closing-trigger operates, while the upper arm of said lever is connected with that crank j of the roller-plane which'is adjacent to it, conveniently by being passed somewhat loosely through aholc formed near the extremity of said crank.

K is the traveling carrier, and 7s the lug on the hanger thereof.

Such bcinga description ofY a good construction of an apparatus embodying my invention, its operation is as follows: In the normal set of the parts theswitch-rail is in alignment with thecontinuation of the main track, as shown in Figs. l and 5, and in this position the movable rollerplane is in the position represented lin Figs. l, 9, and 13. It should here be remarked that the branch track B may, in fact, be a continuation of the main track, Vand the track designated,AX be the branch track, it being of course immaterial to the invention as to where the said tracks A'Xvand B lead or how they are designated. Wfhen a given advancing carrier, traveling by gravity on the inclined main track, encounters by its hangerlug the depending trigger-lug ofthe openingirigger it will occasion a `forward deflection of the said opening-trigger, as represented in 1 dotted lines in Fig. 2, with the result that the trigger-arm e of said opening-trigger will be thrown up and the opening-trigger deiiected fromthe position ,which it is represented as occupying in Figs. l and 6, to that which it is represented as occupying in Fig. 2, and with the further result that the said deflection of said opening-lever will, through its connection with the-crankf, occasion such a movement swinging or tilting of the rollerplanc as will effect the vertical lift of the outer or free extremity of the pivoted switclrrail, as shown in Fig. 2.

. So soon, however, as said roller-plane has been tilted and the switch-rail lifted, as above set-fortl'1, the plane, as willv be obvious first-by a reference to the dotted lines of Fig. 13, and then to Fig.- S, will present such an inclined surfaeegthat the roller connected with the free extremity Y of the pivoted switch rail will gravitate upon the carrying-surface of said plane from the position which the said roller is represented in dotted lines as occupying in said Fig. 13 Tto that which it is represented as occupying insaid Fig. 8, with the result that thefree extremity of the switch-rail will, by such gravitative movement alone, be caused to become aligned with the. continuation of the main track.V This entire action, rst, of the positive lifting of the free end of the switch-rail, and, second, of the uncontrolled vgravitative movement of said free end oi" saidswitch -rail by its rollerover the inclined plane, will take place before the carrier has reached the hinged eX- tremity of and has traveled upon the switchrail. When the said carrier has tripped the opening-trigger, and thereby occasioned the gravitative movement of the switch-rail to a position in alignment with the branch track, as shown in Fig. 4, it will run upon and over said switch-rail until it reaches and travels upon the said branch track. As, then, said `carrier travels along said branch `track its hanger-lug will encounter the depending trigger-luga' of the closingtrigger I as represented in Fig. 3, and, through the deflection of said closing-trigger operatingv by its nose against 4the curved suriacey'X of said closing-lever, will occasion such a deliection of said lever as lthrough its connection with the crank fXX of the movable roller-plane will occasion the deflection of said plane in such manner as, first, to canse it again to lift the lree extremity of the switch-rail, as shown in Fig. 3; and, sec` ond, to place its inclined surface in such position that the switch-rail will instantly upon the completion of its lift, by means ofitsrolier, gravitate over said inclined plane outward until its Vfree end is once more in alignment with the continuation of the main track, so that the next succeeding carrier will find the switch-rail in alignment with the main track, and will in consequence travel across said switch-rail onto said main track unless its hanger-lug is so disposed as to encounter the open- IOO ing-trigger, in which event the entire operation above described will be repeated and the carrier transferred to the branch track.

It will from the foregoing description be readily understood that the whole operation of the opening-trigger and opening-lever upon the movable roller-plane is simply such as to impart a given deflection or inclination to said plane, so that said deflection will permit the gravitative movement of the switch-rail into alignment with the branch track; that, moreover, on the other hand, the operation of the closing-trigger and closing-lever is essentially similar, the carrier encountering the closingtrigger occasioning through the deflection of the closing-lever such a reverse tilt or inclination in the roller-plane as will place the plane in such position that the roller of the switchrail must gravitate over it until the switchrail is again aligned with the main track. The opening-trigger and the closing-'trigger being, respectively, applied to an extremity of the main track and to an extremity of the branch track, respectively, adjacent to the switch-rail, it is obvious that the entire operation of the movementof the switch-rail will be accomplished when the carrier is either upon the main track or upon the branch track, and will not take place while the carrier is on the switch-rail. Both triggers and both levers are applied, respectively, in conjunction with the main and branch tracks simply and wholly for the purpose of enabling the carrier automatically to operate the movable roller-plane, so as by the inclination of the plane to permit the gravitative movement of the roller connected with the free extremity of the switchrail in one vor the other directions across the surface of the then properly-inclined roller-plane. The movable roller-plane, therefore, is a device which subscrves the purpose of being an adjustable inclined plane, adapted to be inclined in either direction, over the inclined surface of which the roller connected with the switch-rail may freely gravitate, so that said switch-rail may by a gravitative movement alone be placed in alignment either with a continuation of the main track or with the branch track.

It may be well to explain that I employ the Word gravitative and the words gravitative lateral77 in this speciiication in a sense not perhaps technically exact, but as indicating both the character and direction of movement of the switch-rail, which,while lateral in the sense that it is from side to side, is gravitative in that it is a down-hill77 movement occasioned by the force of gravity.

It is of course essential that the closingtrigger should be applied to the branch track and be adapted to be operated upon by every carrier transferred to said branch track, as otherwise the switch-rail previously caused through the intervention of the opening-trigger to move its position from alignment with the main track to alignment with the branch track would be left in alignment with said branch track, so that any succeeding carrier` would of necessity travel across the switch-rail onto thebranch track, even if it were desirable that said carrier should travel over the switchrail onto the continuation of the main track. The depending trigger-lug of the opening trigger and the depending trigger-lug of the closing-trigger are therefore preferably of the same length, so that a lug in suitable position upon the hanger of a given carrier to operate the opening-trigger will also operate the closing-trigger. Of course those carriers thelugs of which are not in position to encounter the opening-trigger can never encounter the closing-trigger, because if the-opening-trigger is not operated the switch-rail remains in its normal position of alignment with the continuation of the main track, and the carrier travels along said switch-rail onto said continuation, and the converse of this condition is, as stated, true, for if the lug on the hanger of the carrier is so placed as to encounter the opening-trigger, it must also be so placed as to encounter the closing-trigger, and therefore after a given carrier has beenby the switch transferred to the branch trackl it will of necessity automatically operate said closingtrigger, so that said switch-rail will gravitate back to alignment with said main track.

While I have represented, and with some particularity described, a specific construction of an opening-trigger and opening-lever, and of a closing-trigger and closing-lever, Iyet desire it to be understood that the opening and closing'triggers may be of any suitable construction, and that the opening and closing levers are simply intermediate devices adapted to transmit the movement of the said triggers to the swinging roller-plane, and that, therefore, the triggers themselves may be arranged to operate the plane, or otherintermediate connecting or motion transmitting devices than the said opening and closing levers may be substituted for the same purpose in their stead, with perhaps the same effectiveness of operation, the essential idea of this part of my invention residing in the provision of such a trigger mechanism, to be operated by given carriers, as will, when operated, occasion, either directly or through the intervention of suitable devices, a deliection of the roll er-plane in one or the other direction, the operation of said roller-plane being, as already fully-stated, to present such an inclination of its carryingsurface in one or the other direction as will permit the roller connected with said swinging switch-rail to gravitate over said surface in said direction. Of course, as stated, the switch-roller may be omitted, and a slide or other bearing connected with the switch-rail and adapted to slide or move on the surface of the roller-plane be substituted in its stead.

While I have also shown and described the movable roller-plane as suspended from an axis disposed above it, it is an equally simple construction to support or pivot it from below, and to dispose the opening and closing levers or their equivalents below the framing-plate. In fact, as already stated, the form and mode of application of the said levers, as well as of the triggers and movable plane, areimmaterial to the broad idea of the invention, which resides in the provision of suitable mechanism adapted to be tripped or operated by the traveling carrier, for, through the intervention of an inclined surface, bringing about the gravitative movement of the switch-rail.

It is of course possible for a skillful mechanic to make many modifications in a device such as this, which is essentially mechanical, and all the benefits of my invention flow from the provision, in connection with atrack, a traveling carrier, and a movable switch-rail, of an inclined surface per se, which, through andY by means of any suitable intermediate mechanism tripped, operated upon, or controlled by the carrier, is presented to the switch-rail as a plane over which said rail may take on a gravitative movement in the desired direction, the said gravitative lateral movement being the distinguishing vcharacteristic of my device. The precise form or character of the intermediate mechanism is not, therefore, of the essence of the invention, and any mechanical eontrivance or combination of mechanical powers adapted to be operated upon by the traveling carrier and to permit the lateral gravitative movement of the switch-rail over an inclined surface is adapted, in connection with the positive elements of a track, a movable switch-rail, an inclined surface, and a traveling carrier, to effectuate the said result, and is therefore the mechanical equivalent of the trigger, trigger-lever, and movable plane represented and described.

It is also proper for meto state that while I have represented (in Figs. 1, 2, and 3) and described my improvements as embodied in a switch over which a carrier travels from left to right, yet that it is of course competent for me to rearrange the devices so as to adapt the switch to operate with a carrier running over it from right to left, and that such a change necessitates not only the entire redisposition of the component parts, but also in some instances the application of other motion-transmitting devices than those represented and described. The principle, however, remains the same It is also easy, without departure from the invention, to arrange the switch-rail to move to a branch track which lies upon the opposite side of the track AX from the side on which the track B is in the drawings represented as lying, such a change necessitating simply a local rearrangement of parts.
