fl 10 all wlw/m, it may Concern.'

lie it known that i, tiranni: S. NUNA- Muiiiuz, a citizen oi' the iinited itates, ref siding at lCanton, in the county of titarlr and tita'te oi.I (ihio7 have invented a new and useful lliiay-Carrier, oi which the following is a specifi cation.

This invention relates to hay carriers and .has more especial rei'erence to Cross draft hay Carriers or thaA class otcarriers in which the elevatingl rope leads Afrom the carrier in a direction substantialiy at a right angle to the track alongwhich the carrier moves.

rilhe objects oi the invention are to provide a hay rari-ier oi" the character mentioned with a rope locking' lever which is operated by the elevating-i' rope and which controls the operation oi a rope grip arranged to lock the elevatiifp,l rope at any desired elevation; and to generally improve and sumpV 'ty the construction ot' hay rarriers.

lilith these objeets in view the inif'ention consists in the novei construction and ai rangen'ieilt o i" parte7 hereinafter desoribed, illustrated in the arci)mpanying` drawings, and particularly pointed out in the appended claims, it being understood that various changes in the torni, proportions, size and minor details of construction may be made 'within the scope ot the appended claims, without dejiarting from the spirit or sacriiicing` any oi? the advantages ot the invention.

rllhe invention thus set iiorth in general terinsis ilhistrated in the accompanying drawings formino' part hereot, in whicl Figure l is a perspective view oil" a hay carrier embodyingl the invention mounted upon the track, the elevating rope beingaemoved in order to illustrate the merhanism oi? the carrier.

Fig. 2 is a vertical sectional view through the hay carrier showing the parts in the looked position.

Fig. 3 is a view similar.' to Fig. 2 showing` the parts in the unlocked position.

Fig. 4l is a detail perspective view olf' the rope grip. g

Fig. 5 is a sectional view through a barn showing` the carrier in use.

A practical embodiment otf the invention is disclosed in the acrompanyingi' drawings, formingl a part oi' this speoiiication in which similar numerals ot reference indicate cor1n Specification of Letters Patent.

responding parts throughout the several views.

The traolr i upon which the carrier is adapted to run may be made oi? any suitable or well irnown form and is suspended from any substantial support such as the rafters oi a barn. rThe main traine E2 of the carrier is suspended upon the track traine 3, which is provided at its ends with the rotatably traveling wheels ladapted to run upon the track.

The main carrier frame is preferably formed oi a casting` as shown and comprises two spaced sides joined together at suitable points. The side members ot the main traine are each provided with an upwardly disposed ear 5, a bolt or piu G heine` passed through said ears and through the trames 7 of theV truck frame. It will thus be seen that the carrier with its load is suspended from eight traveling wheels, four being arranged at the front and tour at the rear.

In the main :trame at a point substantially beneath the Center oiY the track is loe-ated the main sheave axle 8, which extends transversely 'from one side of the frame to the other and unen which is rotatably mounted the main sheave 9. This sheave is preterably ot' considerable diameter to lighten the draft as much as possible and facilitate the operation of the carrier.

Pivotally mounted upon the main sheave axle 8 is the rope locking lever 10 which is :termed ottwo similar `members spaced apart, one member being' mounted upon each side of the main sheave, these members being` joined together at their rear and fon ward ends respectively by means of pins or bolts 11 and 12. The rope locking lever extends outwardly to one side of the main frame and is provided with a downwardly depending` portion 13 in which is Carried the roller'14i. mounted upon the bolt 12. A pair of spaced arms 15L are mounted one upo each side ot the rope looking lever and connected thereto by means of the bolt 12. A pulley 1G being.;` mounted between the outer extremities of said arms by means or' a holt 17 or the like.

T he sheave brake 18 is pivotally mounted upon a suitable axis 19 `located transversely through the main frame adjacent to the main sheave 9. The rope grip 2O is prefa erably ot the torni `best illustrated in Fig. tot the drawings and is provided with the of the ropeV grip is curved as shown at 23 and provided with a serrated grooved tace 24, the rope grip being so proportioned and mounted that it will normally rest. upon the rope as best illustrated in Fig. 2. The transverse bolt or pin 11 upon the rope locking leverV` normally engages the under surface of the ropegrip as shown in Fig. 2.

1n reeving-the carrier, one end of the elevating rope 25 is connected to the transverse bar 2G of the trarne either by knotting or by use of a device Vsuch as the rope clamp 27. Extending downwardly the rope passes through'the lifting head or heads of the fork sling or other hay engaging device, in thepresent illustration sling pulleys 28 being shown. The rope then eX- tends upward from these sling pulleys or other hay engaging device over an idler pulley 29fpivotally mounted upon a bolt 50 carried in the main frame, and passes over the main sheave and then outwardly between therollers 14 and 16. upon the rope locking lever. y

From this point the elevating rope eX- tends downwardly atan angle either to the side of the barn in which the carrier is mounted and over' the usual purlin pulley or downward at an angle toV the floor oi' the barn and over the usual floorV pulley, this construction of course'being common in all cross draft hay carriers and is well known 4to those acquainted with the construction and operation Vof cross draft hay carriers and as it forms no part of the present invention 'it is thought unnecessary to illustrate either of these pulleys in the present application.

1t will be understood that the carrier is arranged to be moved longitudinally upon the track in the usual manner by means of the ordinary shift rope or conveyer rope, which arrangement is well known to all those 'skilled inthe art and' has no relation to the present invention excepting that similar nieansv is always provided for Vmoving the carrier upon the track.

The operation of the hay carrier embodyingthis invention is as follows: r1`he parts being in the unlocked position as illustrated in Fig. 3 it will be noted that the rope locking lever is tilted forwardly upon its pivotal point. the rear end thereof being raised, holding the rope grip out of engagement with the elevating rope as shown. 1f, as above mentioned the elevating rope leads downwardly at an angle to the usual Vpulley on the barn floor, the rope lockingy lever is moved into the unlocked position as shown vby graspingthe elevating rope at any point above the floor Vand swinging the rope toward the carrier, the rope engaging the pulley 111 andV tilting the rope locking lever into the unlocked position. 1t, however,V the elevating rope extends from the carrier to the purlin pulley upon the Vside of the barn wall as also above mentioned, it will beunderstood that this purlin pulley is out of reach of a man upon the floor of the barn. For this purpose a trip lever 31 is pivotally mounted at any suitable pointin the carrier Jtrame such as the aXis'22 ot the rope grip and extends inwardly to a point beneath the pin 11 upon the rope locking lever, a cord`32 is connected to the'outerV end of the lever 31 and extends downwardly to the barn tioor. By pulling downward upon the cord 32 the trip lever 31 is rocked tilting the rope locking lever and raising the rope grip. rTheV fall of the elevating rope may then be brought down to the point of attachment of the load. When the load is attached and a pull exerted upon the elevating rope the load will be raised toward the carrier, the ropeV passing over the main sheave preventing the rope grip Y troni gripping the elevating rope. l/Vhen the load has been carried upto the carrier the weight of the load will be sufficient to hold the elevating rop e taut' in a straight line from the main sheave Vto the pulley upon the purlin or Viloor pulley over which the other endV of the vrope passes, the elevating` rope being held in the position shown in Fig. 2

'engaging the pulleyvlG and tilting the rope locking lever upward at its outer end allowing the rope grip to drop into-engagement with the rope as shown in said ignre, they weight of the load pulling down upon the elevating rope, swinging the rope grip down- Y wardly upon its pivotal point 22 causing the serratedsurface thereon to grip the rope tightlyl and pressing the rope against the sheave brake 18, pressing the brake in turn in tight engagement with Vthe sheave, thus locking the sheave and the rope.

It should be noted that with the Inovement of the elevating rope in either direction over the main sheave the rope grip is swung upwardly or downwardly upon its pivotal point, always swingingin the opposite direction vfrom the Y rotation ofl the sheave. Thus it-will be seen that the main sheave itself is locked against rotation by means of the brake 18 and the elevating rope is gripped by the rope grip preventing movementot either the sheave or the rope while in this .position.

rllhe carrier will then'be moved along the track in the usual mannerV to the place of discharge, the loadbeing thus sustained in the position shown in'Fig. 2 whenV the carrier has reached the place of discharge, the sling or fork carried thereby is tripped in the usual manner discharging the load of hay and the carrier. moved back to the loading position, when as above describedpby swinging the elevating rope toward the carrier the rope locking lever is moved into the position shown in Fig. 3 and the fall of the rope be again lowered to receive a new load.

ln Fig. 3 is illustrated an application of the carrier wherein the elevating rope leads to a purlin pulley and then down to a floor pulley 36, a pulley 37 being mounted upon the elevating rope between the carrier and the pui-lin pulley and provided with an operating cord 38 which hangs within reach of the operator and may be pulled down as shown in said figure to pull the operating rope downward and inward to trip the locking lever as above described. After tl'ie carrier has been tripped in this manner it is customary to exert a pull upon the elevating rope to 1aise the carrier, the slack being thus removed from the elevating rope between the carrier and the purlin pulley raising the pulley 37 intothe position shown in dotted lines, the operating cord hanging in the dotted position shown in the drawings. lith this construction the carrier may be used with a purlin pulley without the necessity olf using the trip lever 3l and cord 32.
