Specification of Letters Patent.

Patented Tan. 23, 1906.

Application filed September 9, 1905. Serial No. 277,665.

To all whom, it may concern.-

Be it known that I, PHILIP A. MYERS, a citizen of the United States, residingat Ashland, in the county of Ashland and State of Ohio, haveinvented certain new and useful Improvements in Hay-Carriers, of which the following is a specification, reference .being had therein to the accompanying drawings.

This invention relates to hay-carriers, and more particularly to that type of carriers known as sling-carriers, intended primarily for use in connection with a sling for-sup porting the load or bundle, although capable of use in other connections.

The presentinvention is in some respects in the nature of an improvement upon the construction set forth' in my prior Letters Patent, Nos. 786,455 and 786,456, of April4, 1905, and No. 795,001. of July 18, 1905, one of the objects of the invention being to do away with the alining guide or pulley employed in the construction set forth in said Letters Patent for the purpose of holding the gripping-jaws ,in proper alinement, so as to maintain the load in correct longitudinal position.

The invention has for a further object the "provision of a carrier which may be reversed either by drawing the rope through the carrier in one direction or the other or by causing the body of the carrier to swivel relatively to the carriage, such carrier having gripping devices which positively grip the rope by reason of the weight of the load, the bight of the rope hanging transversely with respect to the track, so that the load is carried in a position which is longitudinal or parallel to the track.

To these ends my invention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a structure embodying my invention in one form. Fig. 2 is an end elevation of the same. Fig. 3 is a plan section taken on the line :1? m of Fig. 1 and looking in the direction of the arrows. Fig. 4 is an inverted plan view showing the under side of the annular flange or track which constitutes the carriage member of the swiveling connection between the carriage and carrier-frame. Fig. 5 is an end view, partly in elevation and partly in section, illustrating the swiveling connection between the carriage and carrierframe and the locking devices; and Fig. 6 is a plan view of the movable part or member of the carrier-frame and the parts mounted or supported thereon detached from the-rest of the apparatus.

In the said drawings, 1 indicates a suitable track, and 2 a knocker thereon, the same being preferably constructed as set forth in my prior Letters Patent, Nos. 786,455 and 786,456. On this track travels a carriage 3, having wheels 4 to fit the track 1. The carrier proper or carrier-frame is connected to this carriage by means of a swiveling connection, so as to permit the carrier-frame to turn around a vertical axis relatively to the carriage when it is desired to efiect the reversal of the carrier in this way. To this end the carriage is provided with an annular flange 5, while the carrier-frame is provided with a grooved annular flange 6 to receive the annular flange or track 5. Preferably the carriage and carrier-frame are made in two parts divided vertically, so as to permit the ready assembling thereof, as is usual in structures of this character.

As in my prior Letters Patent hereinbefore referred to, the carrier-frame is made in two parts, one of which is fixed against vertical movement relatively to the carriage, and is therefore termed the fixed part or member, while the other is free to move vertically relatively to the carriage and said fixed part or member and is therefore termed the movable part or member. The former is designated as a whole by the referencemumeral 7 and the latter by the reference-numeral 8, the same being shown detached in Fig. 6 of the drawings. The member 6 of the swiveling connection is formed on the fixed mtznlaer 7 of the frame, and said fixed member 7 is'provided with a spring-actuated locking-bolt 9, which is mountedto slide vertically in 2. casing 10, carried by the fixed member 7.

11 indicates a spring which forces the bolt 9 normally upward, and 12 indicates an eye formed on the projecting lower end of the bolt, to which eye is attached a cord or rope 13, by which the bolt may be operated. The swiveling member or track 5 of the carriage is provided at diametrically opposite points with notches or recesses 14, adapted to receive the end of the bolt'9. On one side of each notch or recess 14 there is formed an abrupt vertical shoulder or stop 15, located in the path of the bolt and preventing any rota,-

BEST AVAlLABLE COP tion of the carrier in one direction when the bolt is in operative position. On the other side of each of the notches or recesses 14 there is formed an incline 16, so arranged, as indi cated in Fig. 5, that it will ride over and press down the bolt when the carrier is turned in the opposite direction, providing sufficient force be applied to the carrier to effect this result. The bolt, however, when in engagement with either one of the notches or recesses 14 will hold the carrier in fixed relation to the carriage against all ordinary strains which tend to rotate the carrier-frame and will absolutely prevent rotation of the carrierframe in the direction in which the path of the hoisting and hauling rope tends to move it by reason of the offset relation of the gripping-jaws to the central longitudinal plane of the carrier, as hereinafter set forth.

The fixed member of the carrier-frame is provided with the stationary gripping-jaws, which are in duplicate and which are arranged at opposite ends and on opposite sides of the machine. They are indicated by the refer ence-numeral 17 and are shown as separate parts secured by bolts 18 upon supportingledgesl9, forming part of the fixed portion 7 of the carrier-frame and supported by braces 20. The movable part 8 of the carrier-frame is provided with 'movable gripping-jaws 21,

- which correspond in location and number with the fixed jaws 17, above which they are placed. These movable jaws are secured bybolts 22 to plates 23, which are carried by arms 24, forming part of the movable portion 8 of the carrier-frame. The arms 24 are connected by arms 25 with a yoke 26, which slides in vertical guideways 27 in the fixed part 7 of the carrier-frame. The arms 25 also carry the pulleys 28, which are arranged on opposite sides of the machine and also on opposite sides of a transverse plane centrally intersecting the machine. Their pivotal axes are indicated at 29, and. the fixed portion 7 of the frame is cut away, so as to permit them to move vertically with respect thereto.

I have shown each pulley as provided with a guard 30, which for convenience of manufacture is made in one piece with the corresponding movable jaw 21. Each pair of grip ping-jaws is provided with a funnel-shaped guide or mouth 31, preferably attached to or formed in one piece with the movable jaw and serving to maintain the proper relations between the rope (indicated at 32) and thegripping-jaws. These guides also serve as stops when the carrier is reversed by pulling the rope through it. For this purpose there is formed at each end of the rope 32 an enlargement 33, usually in the form of a knot, as indicated in Fig. 1, said enlargement being of such size that it will not pass through the guide 31. The rope is pulled through the carrier until the enlargement at one end or the other lodges in the guide of the correspond of the sling-blocks 35.

ing end of the carrier, as indicated in Fig. 1,-

length to reach the ground or barn-floor and enable the operator to grasp the same for the purpose of reversing the carrier by pulling the rope 32 through the same in the manner described.

It will be noted that the pulleys 28 are so 7 arranged that those portions thereof from which the bight of the rope 32 depends are practically in alinement transversely of the machine. It follows from this that the bight of the rope lies ina transverse plane with respect to the machine and track, the slingblocks 35, supported by this portion of the rope, being so positioned that the bundle is longitudinal, extending with its greatest length in the direction of the track. This is a matter of material importance in the handling of the loads, as it obviates the necessity of swinging the bundle around to this position when it has reached the place where it is to be discharged and-also the necessity of providing special devices for effecting this turning of the bundle.

The trip devices are preferably constructed in substantially the'same manner as in my prior Letters Patent hereinbefore referred to.

The yoke 26 is provided at its upper end with an extension 36, terminating in a head or enlargement 37. The carriage 3 has mounted in it on each side levers 38, pivoted to the carriage at 39 and having arms 40, which extend under the head or enlargement 37. The levers 38 also have arms 41, carrying rollers 42, which cooperate with the cam-surfaces of the knocker 2, sothat when said rollers come into contact with the knocker the arms 41- are forced outward and the arms 40 upward, engaging the head or enlargement 37, and thereby lifting the yoke 26 and all of the movable part of the carrier-frame, including the movable gripping -jaws. The yoke carries a transverse pin 43, which is adapted to be engaged by a dog 44, pivoted to the fixed part of the carrier-frame at 45 and having connected to it the tripping-plate 46, which lies in the path When the movable frame member is lifted by means of the knocker in the manner already described, the dog 44 engages by gravity the'pin 43 and holds the movable frame member in lifted position, with the gripping-jaws open. When the sling-blocks 35 come into contact with the tripping-plate 46, they lift said plate and disengage the dog 44 from the pin 43, permitting the movable frame member to fall. Since the'entire weight of the load is supported by the pulleys 28, which are in turn supported by the movable frame member 8, this weight acts to force the movable grippingjaws 21 BEST AVAILABLE COP the rope 32 tends to move while the' load is being transported along the track, it will be understood that there is no tendency of the gripping-jaws to slip, such as is present where the supporting-pulleys form an element of the grip 'iing aws In order to obviate the necessity of hoisting the load to a height such as to cause the sling-blocks 35 to automatically drop the ropelock, I provide a rope 17, connected to the tripping-plate 46 and passing over a pulley 4:8

' on the fixed part 7 of the carrier-frame, whence it extends downward, so-as to be conveniently reached by the operator. By means of this a rope 47 it is possible to lock the load with respect to the carrier as soon as it has reached any desired height, so that it is not necessary in the earlier stages of the operation of building up the piles of hay to lift the load to the maximum height in order to automatically operate the tripping mechanism.

The general operation of the carrier is the same as that of the carrier described in my prior Letters Patent hereinbefore referred to. When the carrier returns to the loading-place, where the knocker 2 is located, the movable portion of the frame will be lifted through the medium of the levers 38 and the gripping-jaws will be opened, so as to permit the bi ght of the rope 32 to be lowered to a position such that the sling-blocks 35 may be connected to the sling which carries the load.

' The header enlargement 37 engages with the knocker in such a way as to prevent the car rier from moving along the track, so that when the rope 32 is pulled the load will be hoisted to an elevated position. This hoisting operation continues until the tripping mechanism is actuated either through the rope 4:7 or by reason of the contact of the slingblocks 35 with the contact-plate 46. When the tripping mechanism is thus operated, the dog 14 is disengaged from the pin 43 and the movable member of the carrier-frame falls. Drawn down by the weight of the load the gripping-jaws 21 firmly clamp the rope 32 against the gripping-jaws 17, so that the rope cannot move relatively to the carrier. At the same time the head 37 drops below the knocker, so as to permit the carrier to move along the track, and the load is drawn along the track by means of the rope 32 to the point where it is to be discharged, being conveyed with its longer axis in the direction of the track, so that it is ready to be discharged in nosition in which it arrives at the place of r In case it is desired to reverse f travel of the carrier from the may be accomplished either by drawing the rope 32 through the carrier or by turning the body of the carrier around relatively to the carriage from which it is suspended. In the former case the reversal is effected by pulling the rope through by means of either one of the smaller ropes 34, connected to its ends, until the knot or enlargement 33 at the farther end of the rope lodges in the guide 31. In the latter case it is only necessary to exert a pull in the proper direction upon the rope 32, whereupon the bolt 9 will yield, sliding upon the incline 16, and the carrier proper will make a half -revolution relatively to the carriage, being automatically stopped by the contact of the bolt- 9 with the stop-shoulder 15 on the opposite side of the turn-table or swiveling connection between the carrier proper and carriage. If desired, the bolt 9 may be released at any time by a downward pull upon the rope 13.

It will be noted that in order that the bight of the rope shall hang transversely with respect to the carrier the pulleys 28 must be laterally offset with respect to the central longitudinal plane of the carrier, and since the grippingjaws are arranged in alinement with the pulleys said gripping-jaws are also laterally offset with respect to said central longitudinal plane. It therefore follows that when traction is exerted upon the lead of the hoisting and hauling rope 32 to cause the carrier to travel along the track the pull of said rope is not central and there is a tendency for the body of the carrier to turn relatively to the carriage, the guide 31 tending to move into the plane of the track. This turning tendency is effectually resisted by the locking mechanism which I have provided between the body of the carrier and the carriage.

It will be noted that the offset stop-shoulders 15 are so located that the pull of the rope 32 tends to bring the bolt 9 against the shoulder 15 of the particular notch or recess 1 1 with which the bolt is engaged, so that no movement of rotation of the body of the carrier is caused by the hauling on the rope 32. At the same time it is possible to reverse the body of the carrier by turning it in the opposite direction, although the bolt 9 effectually prevents accidental displacement of the body of the carrier relatively to the carriage. This feature of myinvention is applicable not only to the particular type of carrier here shown, but also to the other types of carrier set forth in my three prior Letters Patent hereinbefore referred to and to other carriers of the swiveling class. It will be noted that this looking mechanism is entirely independent of the hoisting and tripping mechanism, so that the carrier may be turned to reverse the direction of travel irrespective of whether the load is hoisted or not and irrespective of the position of the tripping mechanism.

I do not wish to be understood as limiting myself to the precise details of construction BEST AVAILABLE coi hereinbefore described, and shown in the accompanying drawings, as it is obvious that these details maybe modified Without departing from the principle of my invention.
