CABLE-CARRIER SYSTEM.

Specification of Letters Patent.

Patented Oct. 19, 19155.

Original application filed July 17,1913, Serial No. 779,449. Divided. and. this application filed January 8,

' 1914. Serial No. 810,979.

1'0 all whom it may concern.

Beit known that I, FRED R: TAISEY, a citizen of the United States, residing at Lowell, in. the county of. Midd'lesex and State of Massachusetts, have invented certain new and useful Improvements inCa'ble- Carrier Systems, of which the' following is a specification. I

This invention relates to apparatus, disposed at stations of a cable carrier system, for despatching and receiving carriers, and is particularly adapted to what are known as high-line dropstations in systemsof this character. Features thereof may also be employed to advantage in low-line systems, and indeed in systems other than those using a cahle for the transmission of carriers.

The present application'isa division of my application entitled-cable carrier system, Serial No. 779,449,'file'd July'l7, 1913, and relates more particularly to certain features of construction and combinations of elements which were shown by wayof exemplification in my said former or parent application but which were not claimed therein.

One of the objects of the presentinvention' is to provide an improvedme'ans for elevatinga carrier from a station or point dis posed at a relatively low level, to a track at a higher'level andthen to automatically connect the carrier to a propelling cable or.

otherwise subject it to a propulsive effort, in

such manner as to avoid collisions with other carriers en route past the station;

Another object of my invention'is to pro-' vide a carrier-holsting mechanism which is set into operation by a downward pu'shupon the carrier itself, after the latter has been inserted in said mechanism. V

I have further aimed to provide an improved means whereby this hoisting mechanism may be intermittently operated, as needed, by power derived from thecable or like means which propels the carriers along the main track.

Still another object of the invention to provide an improved means for operatively engaging and disengaging carriers with the propelling means.

I These and other objects of my invention will be hereinafter referred to and the novel elements and combination of elements whereby they maybe attained will be particularly pointed out in the claims appended hereto.

In the drawings 1 have exemplified certain preferred forms of the apparatus in question, but I am aware that various other changes and modifications than those shown may be made herein without departing from the spirit of my invention and 1 hence desire to be limited only by the scope of said claimsbroadly considered in the light of the specification.

Referring to the drawings: Figure 1 is a front elevation of a high-line drop station. Fig. 2 is a section of the apparatus shown in Fig. 1, taken on line 11H of said figure; the station proper being shown in side eleration. Fig. 3 is a detail section taken on line IHI1I of Fig. 1. Fig. i is a fragmentary rear elevation of the mechanism for tripping free the carrier cablegripping device and for thereafter causing said device to reengage the cable. Fig. 5 is a front elevation of a modified form of high-line drop station; the carriers on the main track having in this type of apparatus the right of way over carriers being delivered main track from thestation.

The main track in the present instance comprises an upper or incoming track 1 preferably adapted to support carriers hori-.

Zontally; both portions of the track being disposed in .a horizontal plane in a known manner. The lower, or outgoing track in the apparatus exemplified has the rails 2 2 thereof disposed in the same vertical plane, but I do not wish to be limited in any way to such disposition of the railswhere the claims do not clearly specify such arrangement'.

The main tracks have been respectively designated forwarding and return tracks with respect to the drop or clerks station and not with respect tothe cashiers station. A track comprising rails 33 extends up vertically from a pointconvenient to the operative and is adapted to deliver carriers to the track the rails of which have been designated 2, and which may hence for brevity conveniently be referred to as track 2, when a switch 4 is in its elevated posi- 4 tion, indicated by dot and dash lines at A cable 5 serves to propel carin Fig. 1. riers in the direction indicated by the arrows,

adjacent thereto, along the respective main tracks; and this cable it will be noted is normally substantially free from kinks or bends where passing a station of the character in question; a feature of considerable im-' portance, An independent drop track 6 6 is adapted toreceive carriers from a switch 7 to which selective carriers are delivered in a known manner from the upper or. horizontal track 1. The respect ve. track sec tions and switch are suitably connected together' and supported by, brackets or connections 8, 9,10,11, 12, 13, 14L, l5 and 1 67; the switch 4 being mounted upon a shaft 17 journaled in the bracket 9 and most of the remaining brackets serving further to support operating cams, or the like, in the manner hereinafter described.

The shaft 17 has mounted thereon adjacent its rear extremity an arm'18 which has journaled in its free enda spindle 19upon the rear extremity of which iskeyeda spool 20 and upon the inner end of' which is a small-pulley 21. This pulley preferably 7 V periphery'22rthereof to better adapt it for provided with a roughened surface at the driving engagement with the cable 5.

' Journaled in the lower portion of the bracket 10 is an idler 23 uponwhich norattached to a pusher 25, which, as indicatedf mally the cable 5 lightly rests, but which,

when. the arm 18 is rotated into its position indicated by dash and dot lines 18, kinks or bends the cable into driving engagement with the pulley 21. At suchtime obviously the spool 20 will be rotated in the direction ofthe arrow adjacentthereto and said spool will thereby wind up upon itself a hoisting cord 24. This cord has its lower extremity in Figs. 1 and 2,r'ides between the rails3-8. Thispusher may be made of fiberoruother suitable material and carries a hook 263, the.

function of which will be hereinafter .referred to. The respectiverails 3 are bent out as at 27 to providean opening'through which the guide or retaining lugs 28 of the carrier 28 may be inserted into operative engagement with the pusher .25 as shown in Fig.1!

he carrier28 may be ofvany suitable description adapted to co-act with the rails, but it is preferably of substantiallythe form shown in Fig. 4; ,the bottom of the carrier, carryinga cable-gripping lug 29, ,and being slotted as at 80, in a known manner, to, per:

mit the projection through :said slot-of a pivoted cable-gripping member 31.

To djespatch. the carrier it is pushed Wardly by the hand of the operative and therebydepresses the pusher 25 to its dotted line position 25, shown in Fig. 1. This causes the hoisting cord 2st to swingthe arm 18 downwardly until the pulley'2lis in driving'engagement with the cable 5. The bridge l-is raisedat the same time toi its dotted ll I16: position v4and these parts are held in such position by a latch 32,cpivotedv at 33.toanl extension of the bracket 9; the

operating position of latch 32 being indicated by dotted lines 32'] and the latch;at

such time being in engagementwith aishoulw alternately of thereduced sections 37%37 of the longer rail3and upper rail'2,so.that

whether the bridge is down or up, itjis rig-i V idly: held against lateral movement- :The rear'side of said bridge, as Viewed invFigz; 1, V

carries aolmoblvor' buttonl 38 whichextends out beyond thecable 5 so that as the bridge is elevated the cable first; engages the round:

edhupp er: surface of this-button and then 7 r slips downwardly thereover till it rides over the: preferably bluntly pointed extremity '39 andlaround against the curved .under s'un.

face 40 ofsaidbutton, as indicated in Fig.

.This featureis ofgreatimportance since this; exceedingly, simple device provides means for enabling the ascending carrier to dispose the cable 5between .the jaws of-its grip reason of the fact that the jaw 29 pressesh upwardly l against the cable as the,

carrier emerges "from track 3,. which in turn presses the ,cable upwardly against the cam acting surface 4:0, and the shape of the latter is suchthat .thezcable is displaced sidewise V '7 tof clear :lug; 29; the cable,fbeing under tension, thereafter emplacing itself under said lug, sothat when the pivoted grip member 31 encounters the :grip closing cam 41, the" carrier is at once operatively engaged with thecable, spring 42"gives the latch 32 a bias for its operative position, While a spring 43 tends tov return the bridge and its associated movable, parts 'to their normal posi-f 'ti0I1S,-' shOWin in fulllines in Fig..l.- g V W eau e carrier has been nearly entered upon track-,2, the cam acting upper surface of the hook 26, at the side of the pusher e ges a; Proje on po th lat and swingsftheilatchv to 7 its open, 'po i ti p releasing the bridge/ v The bridge-cannot rop, however, 7 more than sufficient: to

pusher returns it to its. normal or lower position; cord 24 unwinding from its spool and the parts described ibeing then-in =posi-' tion for the despatch of a second carrier.

The means for preventing collisions between carriers en route along main track 2 and 7 carriers being despatched from the clerks station will now be described. Pivotally connected at 45 to the arm 18 is a bent link 46, the right hand end of which, as viewed in Fig. 1, is connected at 47 to an L-shaped member 48. e The latter is pivoted at '49 to the bracket 12 and the distance be tween the pivotal axesf47 land 49 is substairtially equal to the distance between the pivotal axes 45 and 17; so that the straight half of link 46, adjacent member 48, always moves :in parallelism with itself and, it may be noted, in parallelism with track 2. intermediate members 48 and 18 is a second L-shaped part 50 which is pivotally connected to the link 46 at 51 and also pivoted at'52 to bracket 11. The distance between axes 51 and 52 is again made equal to that between axes 47 and 49, and obviously members 48 and 50 rotate together, clockwise or counter-clockwise as the casemay be;

The free end 53 of the member 48 is bent over as shown to adapt it for engagement with the pivoted element 31 of the carrier grip, so that when'a carrier'traveling over track, 2 approaches a station from which a carrier is being despatched and the bridge of which station hasbeen raised, its pivoted jaw or grip 31 strikes said end 53 and such carrieris released from the cable to continue on by momentum, alone until it strikes the vfree end 54 of the member 50 which at such time is disposed in its dotted line 'posi tion. This element positively stops the carrier. It will be observed, too, that the element v54 is also adapted to open the grip of 7 it has passed member 50. It may also happen that two carriers are en route over track 2 immediately behind each other in which case both will be disengaged from the cable and brought to rest immediately to the right of-the stop 54. Assuming now that one or more carriers are so disposed, theimoment that the carrier beingdespatched from the station has passed from beneath the bridge v4, thewlatter closes and thereby the gripopener 53 and combined grip-opener and stop 54 are lowered while simultaneously the bar or link 46 is raised. The straight portion or the bar, when the bridge is open, lies immediately below the grip elements of the arrested carrier on track 2, so that as it rises its upper edge 46, indicated by dotted lines in Fig. 4, engages the pivoted jaw 31, shown by dotted lines in its lower position in said figure, and presses it upwardly a sufficient distance to enable the jaw to be snapped closed by its spring in the interior of the carrier bottom; although the movement of the cable alone when the pivoted jaw is brought into contact therewith will normally pull this part around the remainder of its travel into apposition with co-aeting jaw or grip element 29.

Since the straight portion of the link 46 is relatively quite extended it is adapted to effect the engagement of a plurality of carriers with the cable simultaneously, and hence the one or more arrested carriers immediately resume their travel over track 2 eral guides (not shown, since these are in a common use) with the switch 55, in a known mannergthe usual spreader or aperture 56 in the track 1 belng provided to enable the carrier guide lugs 28 to free themselves The usual grip opening 1 =1 from said track.

cam 55 is provided and the carriers are dey livered-to track 6 in a known manner, de scending this track until they come to rest in the relatively small radius loop 57. The

novelty in this prefer-red receiving track, It:

per 86, principally resides in the provision of oblique cuts 58, in the respective rails thereof, at substantially the entrance to the loop 57, which permits of the ready withdrawal of lu' s 28" of a given carrier therethrough while leaving no opening, such as at 27, through which a carrier may become inadvertently disengaged from said rails.

As the carrier is lifted back-ward from the loop up toward the cuts 58 its lugs 28 easily enter themselves in these cuts by reason of the natural slight cant given to the carrier by the hand of the operator, while if several carriers have accumulated in this receiving track, the one in the loop grasped by the hand is removed whilethe others thereabove are lifted slightly so that but one carrierneed e removed at a time.

Referring now to the construction shown in Fig. 5. Herein the carrier traversing track2 has the right of way over carriers being despatched from the station shown. The parts not otherwise particularly noted are substantially the same as in the previously described form of device and hence need not again be'referred to. V i

slotted one, to permit of freemoveme'nt between the connected elements, and it operates in the following manner. Assume that a carrier 28.is just being despatched when i and its outer end upward as also indicated despatched will afford a suificient pull downwardly upon the hoisting-cord, as they reach a carrier on themain track 2 approaches the station, as indicated by the dotted outlined carrier shown to the: right on said track, in Fig. 5. The clockwise move- 'ment of the latchas bridge, 4 is opened swings the inner end of lever .60 downward by dotted lines in said figure. This disposition of the treadle-like free end of lever 60, however, places it in the path of the ap-- proaching carrier and if it has not re-descended'before this carrier encounters it, it will be positively depressed by the engagement of said approaching carrier therewith,

which will rock the lever clockwise and the latch counter-clockwise, releasing the bridge, when spring 43 immediately closes the same, at the same time liftingpulley 21out of engagement with cable 5, so that the pusher 25 descends prematurely and with it thecarrier being despatched, unless the latter has already succeeded in so nearly-entering track 2 that its momentumcarries it out com pletely thereinto; in which case its grip will engage cable 5 and both carriers will travel on thereafter one closely behind the other.

;The spring 43 may, if desired, be so ten-. sioned that the momentum of the follower or pusher 25 plus that of the carrier being substantially their lowermost positions in track 3, to effect a reengagement of the pulley 21 with cable 5 and a 're-latching ofthe bridge in its up-position'. In suchcase the action is as follows: The carrier being idespatched has, let us say, reached bracket 18,

when the carrier on track 2 trips the :latch and thebridge closes, this latter carrier'im-' mediately passingv thereover, By the time that the through or main line carrier has cleared the bridge, however, the pusherfand' the carrier supported thereby will have.

dropped until they have nearly reached the osit-ion's in which the areshown in Fi 1,

Thereafter they will continue to descend under momentum and by gravity until the bridge is again raised and latched and the pusher again drawn up, Thistime, if there be no immediately 1 succeeding carrier on track 2 (which seldom happens) the pusher a 25 willbe pulled up sufliciently to discharge 7 its carrier load onto track 2 in-the manner above described I desire to call particular attention to the provision of movablemeans, e'. gfc'ams, trips orthe like, suchas the parts .53, 54 and 46 or 46, for arrestingdetermined carriers unjder certain conditions and for efi'ectingtheir reengagement' with, "or re-subjection to the influence of, the cable. or f -.otherpropelling means. I V The prov1s10n-of.means for recelvlng carriers from thereturn' track which aresubstantiallyindependent 'ofthe power-driven f carrier delivering mechanism is of especial value in a system of the character described since it permitslof the despatch oficarriers from-the stationby said mechanism without interference therewith .by carriers arriving at the station. i Finally, it will be noted, that the track or way'leadingffrom the station the same gage as said-forwarding track, the
