To .f2/,ZZ- iti/tom t muy concern:
Be it known ,that I, DAVID M. MOTHER- wnnL, a citizen oi the United States, residing at Chicago, in the county or Cook and State of Illinois, have invented certain new and usei'ul Improvements in Traveling Carriers, of
' which the rollowing isa specification,rererence being had therein to the accompanying drawings.
My invention relates to traveling carriers which operate to raise a load vertically, convey it horizontally supported trom an overhead way, and release it at a desired point.
The object or the invention is to provide' a carrier which may be locked on the overhead stop while the load is secured in a sling or` other convenient attaching device, hoisted, tripped atany desired elevation in such a manner that the snspendingrope grasped with a force approximately equal to the entire weight or the load, and, thus suspended,
. conveyed to the unloading-point, where the sling or'attaching device vvis operated to rer lease the load, the carrier being then sw iveled about and drawn back to the loading-point onto the stop which operates the tripping mechanism and unfastens .the suspendingrope and sling, permitting them to be low. ered1 in proper position ror taking on a new loa The invention provides means by which the load is 'released with its length at right .angles to the path of travel thereof, thereby saving labor in pitching or shifting the loads alter releaseV and it also provides a trip-lever which may be set up o n the track at any point and which is controlled'by a guide-rope independently oi'the carrier.
My invention also provides means for, holding the car firmly in the stop, and it contemplates a compact, safe, durable, and economical construction of the parts.
In general my device comprises, in connection with an overhead track, a stop and carriage, a lower swivel-frame, and an inner tripping-frame carrying the pulleysv uponwhich the sling or other attaching device is secured.
In the accompanying drawings, wherein like letters and numbers refer to similar parts throughout the several figures, I have shown a device embodying my invention.
Figure 1 is a side elevation of the hay-can, rier suspended upon a section of track. Fig.
oi Big. 5, the same being shown as detached orindependent of the traveling portion ofv the car. Fig. 5 lis a transverse sectional view of the car, takenon line 5 of Fig. 1. Fig. 6` is a sectional end view on line 6 of Fig.. 3.
In ,the drawings, A indicates the'main truck or carriage, B the outer swivelaine, and C the inner trippingdrame, which turns with the swivel-frame B, but drops and rises within it as the tripping dev ice and lockingdog are operated. As a matter of conven` ience inconstruction I prefer to make the carriage A and frames B and C in halves or sections.- A comprises the sections A A2,- bolted together at the points 7 7. .This can iiage is provided with the truck-trames 8, to the upper corners of which are secured in the usual manner trucks or wheels 9, adapted to run on flanges 1@ of overhead track 11 and support the carrier.` The carriage A bears on its lower extremity the two halves of the circular swivel-collar 12, in which reversible gripping-frame B is supported by,rneans of circular guide-flange 13, adapted to turn freely in channel 14A or collar 12. Frame B I prefer to construct in two parts B B?, bolted together at the points 15 15.. Sup ported by BB2 is the movable inner sheave-` frame C, likewise referably constructed in` two parts C and -2 and bolted together at or guide pulley 23, the projections 20 and 21 at an angle to the horizontal, -so
being placed that pulley 23 dips in the directionof pulley 18. This pulley serves asa support for the draft or suspending rope R in turning at right` angles in the f1 ame, both in the free and locked position ot the rope. This construe# tion enables me to support 'the load sothat its long wav is carried at approximatel lright angles to the direction of'draft and de ivered .in thisposition. It also prevents'the rope ILO from burnini es." rubbing, and thus damaging l 50, draws clamp 55 in'contact with the draft or wearing out the parts and 'causing the mechanism to stick or stall.
On the frame B are. provided projecting supporting-arms and 26, extending in the direction 'of draft, and bolted thereto at 29 and is a gripping-bracket 27, upon the outward end of which are placed suitable vertical guide-spools 31 and32 on veltical axles 33 and 34, bound together at the tcp by a strap 35 riveted tothe axles. Secured to the lower inside end of bracket 27 cr cast integral 4therewith is a supV citing-brace 36, .L carried around from the iiorizcntal to the vertical to bear against the central side por-.
tion of frame t1. 0n the end adjacent to frame C is a vertical guideway 37, land upon the surface et the frame C is a vertical earlug 38, adapted to constantly engage and move freelyv up and down in the channel 37, thus preventing the frame C from swinging outof vertical alinement.- lprefer to cast this lug integral with the frame C.
The hais A and Al of the carriage A are provided with oppcsitely-dispcsed ways or guides 39 and 40, adapted to prevent. central locking-dog 41 from moving out of the vertical. Central locking-dog 41 is provv ided with side arms 42 and 43, adapted to move up and down in the ways 39 and 40, and it comprises besides the aims described a shank having a head 44 adapted to be engaged by and raisedin ways 45 and 46 of stop S cn the overhead track 1-1. To the lowerportion of this shank is secured by bolt 48 a collar 48, provided with an annular groove 4S", en-
gaging an annular iange 47 within frame C,
thus making a swivel connection between dog 41 and frame C. Thus dog 41 hast only vertical movement within. the cari' iagc A, but is secured to and moved with the trame C in its vertical movement, but not in its swivel movement.
Projecting from the frame B in the direction opposite to that of draft is a bracket 49, to which is fulorimed at the point 50 a lever 51, passing through a recess opening in frame C. Lever 51 is ivoted within the recess 52 to the two ha ves C and C2 of the frame C at the points 53 and moves with the latter. Cn the opposite end lof lever 51 is pivoted at 54 a movable and swinging rope-clamp member 55, so arranged that it 1s suspended directly above bracket 27,Y
which forms the stationary .member of the rop.eclutch. Clampv 55 and bracket 27 haver draft rope, and likewise when head 44 is released from the ways in stop S lever 51,
rope to firmly engage it on bracket 27. As
27 and clamp 55 are oppositely-disposed intermeshing crimps adapted to form a clutch.
Pivoted at the point 57 to extending arm 58, attached toframe B at the point 59, is the compound tripping-yoke D. This yoke ,extends beneath the car and is carried around and upward at the other end to the point 60, where it is pivoted at the point 60 tothe link 61, which 1n turnis pivoted at the point 6M tripping memberf63, pivoted at '15 to the frame B; The free or upper end of `tripping'member 63 extends within the part A of the hay-carrier, where it encircles the swivel-collar 47 'of the vframe. C. This provides a swivel-ring 64,v so that the parts jrst described may"turn or swivel with the frame B. Pivoted to B at the point 66 is the compound lever L, which consists of the link 65., pivoted at 67 to B, and the trippingdog or crank member 68, pivoted to B at 66 `and to link at the point 69. The outer end of the lever'Lcis extended and pivoted to D at the point 7 0.
In order to trip the loadv at any desired elevation, I provide near the stop S the handtrip T, which consists of upright arms 71 and 72, bolted on the central or web portion of the 'overhead track 11. -These central arms carry an axle 73, on which is pivotally mounted a lever 74, carrying at one end a suitable eye 75 for the attachment of a rope or hand-cord, and a contacting surface 76 at the opposite` end, adapted to thrust, the
Within the frame B2 is`a vertical way or channel 7 9, adapted to receive the lug or guide 80. -This lug or guide is preferably cast integral with the frame C, and the channel andlug are placed directly over the member 81' of dog 68. It will thus be seen that by operating the lever L to turn bell-crank 68 on its ivot 66 that frame C may be alternately he d in elevated position and lowered within the frame B. In the position shown in solid lines in Fig. 6 the frame C is held in its elevated position; but when the tripping. lever D is 4thrust intothe position indicated by dotted lines in 'the samevgure the member S1 is swung out from under the lug 80, so that the frame C drops, carrying with it lever 51 and gripping the draft-rope in the clutch. T he operation. 0f`my device isas follows: The stop S is .secured to the .overhead track at the point most convenient for loading.
ICS
The rope Ris then carried over the pulley 19 and at the low er end secured to an eye 83 -in block-pulley P. i The other 'end is then brought through pulleys l) I, then over pulley 18, over idler 23 between spools 31 and 32, and connected with power. The carrier is then mounted on the overhead track, and the central locking-dog raises the frame C as the head .44 slips into the inclined Ways and 46. The tripping member is then thrown into the position shown in solid lines in Fig. 6, the dog 58 supporting the frame C by means of member 81 and 'lug 80. l The load is then attached in the ywellfknown manner to the hooks on pulleys P and P. In my device it is not necessary that the pulleys lr' and P should be elevated tolsucha height as to contact with the lever D and free the carrier from the stop. In order to save unnecessary'` labor, it is only necessary that the load should be elevated to a height desired to clear the ground. As soon as this height is attained vthe carrier may be freed from the stop and the load locked in. position by bringing lever 7,4 down into contact with plunger 77, thereby causing the plunger to depress the ,collar 64 and elevate the member 63, therebycausing the lever D to .turn upon the pivot- 57, raising end 65 of lever L to operate crank member 68 and draw member 81 from under the supporting-lug 80. The weight of the load itself causes the entire frame (l to i'all, carrying with it lever 51 and causing dog 55 to bite the ro e between its under surface and the brac ret 27. 'Ihe rope is 'thus grasped and lirmly held by the entire weight ot the load. 'Ihe hay-carrier is then-drawn, by means of the rope R; in the direction indicated by the arrow'a in Fig. 3, and the car is brought to the unloading-point. The load is then 4released from the sling in the usual manner and the car is drawn back toward the stop S, where the inclined ways 45 and 46 grasp the head 44 of the central tripping-dog and lil't the frame C. thus raising lever 51 and releasing the rope from' the Aclutch or clamp 55 and bracket27.
It will be apparent lromthe foregoing that the tripping may be" accomplished either by' means of the device T or by the `frame oi the pulleys P and I contacting with the lever D directly. 'Inthe latter case the freeing of the' load is the same, the use of the trippmg device T and plunger 77 being unnecessary. 'I his method of tripping may bef-most conveniently used in building Ithe top of a stack.
To prevent the end of the car nearest the draft from raising off-the track, I have provid ed the stop S with longitudinal grooves or channels and 86 and the parts A and A2 with oppositely-disposed lugs 87 and S8, adlapted to engage or run Within these channe s.
WhileI have described this particular embodiment of my invention in detail, I realize that there are considerable variations -in details of construction which may readily be made by persons skilled in the art without departing from the spirit of my invention,
