LOADING DEVICE.

' Specification of Letters Piatent. Patented-S t 27 1921 Application filed October 22, 1920.: Serial No. 418,859.

To all whom. it may concern:

Be it known that I, Jncon PLni'N, a citizen of the United States, residing at Plainview, in the county of VVabasha and State of Minnesota, have invented certain new and useful Improvements in Loading Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the to place and which is of great adaptability.

Another objectofthe invention is to provide such device which may be readily taken I I bers have been shown, it will be understood,

down and disassembled and which, when so disassembled, can be stored 1n a comparatively small space. 1

These and other objects of the invention will become apparent as the description proceeds in connection with the accompanying throughout the various views,

drawings in which like reference characters are used to and in which V V Figure 1 is a diagrammatic view showing the device and one method of using the same;

, any suitable construction which is supported 7 g This structure comprises two blocks 18 ara pivot 5, and which is adaptedto swing Fig. 2 is a central longitudinal section of the boom device proper;

Fig. 3 is a perspective view of the loading fork constituting a part of the device; and Figs. 4 and 5 are details of portions of the boom and the sheaves carried thereby.

Referring to the drawings, the loading device comprises a portable structure A, the

load carrier B, and the operating cable C.

The device A comprises a platform 1 of l, which will be used to securelyset or an chortliefdevice in any desired position. Lo

cated centrally transversely of and at an intermediate part longitudinally of the platform 1 is a post member .4: whichis pivotally mounted to the platform at its lower end by in a. plane disposed longitudinally of the device. When erected to vertical position, as

, shownin' Figs l and 2, the'post' is securely designate the same parts braced by rods6, 7 and 8. The rods 6 extend form approximately the same distance from.

the center of the post as are the corners to which the members 6 extend. The members Sexte'nd from the side of the post to points on the platform at each side of the post and at equal distances from the base thereof.

The supporting members 6, 7 and 8 are preferably connected to the post by having loops 'formedat their ends adapted to embrace a bolt 9 which passes through the post and is suitably secured therein.

eye bolts lO'which are secu'redin the plat-. form 1. 'l Vhile eight of these bracing mem- I At their lower ends, the members are preferably formed as hooks which are adapted to engage suitable that any desired number may be usedwliich may, if preferred, be connected at different vertical positions along the sides of said post. At the top thereof, the post 4 is arranged to support a boom member '11. This boonr,

member, as shown, comprises two spaced longitudinal members 12 connected at their ends by members 13, these members being I secured together in any suitableymanner. At

an intermediate point, somewhat-nearer one end than theother, the boom has'bolted thereto an'upper member 14 and lower heavier'member 15. Passing through these members and designed to be seated inia central socket in the post 4 is a pivot member 16, by means ofwhichthe boom member 11 is mounted for swinging movement in a horizontal plane. The boom member 11 is arrangedto projectoutover the end of plat form 1 nearest which the post 4: is located- Between this end of the boom and the post is located a sliding sheave structure 17.

ranged to slide upon members 12. Supported at each end of the blocks 18 and suitably secured theretoby-screwsor bolts 19 are Y-shaped brackets 20 having their central portion depending betweenthe memi bers 12 and formed with a bearing 21% their lowerends. A rod 22 is mounted in U these hearings and projects from one of them at the side adjacent the end of the boom. The sheave housing 23 is mounted on therod 22 for swinging movement thereon and has 'journaled between itsdepending side 24*. v

sheave 26. The projecting end of rod 22 has an eye or loop 27 formed thereon. An eyebolt 28 is secured in the end piece 13 of the boom between the members 12.

A sheave or pulley 29 is mounted in alinement with the space between members 12 between the post 4 and the other end of the boom. This pulley is carried in suitable brackets 30 mounted on the underside of member 12. This end of the boom projects above the platform 4, and a depending sheave structure is also mounted at this end. This structure comprises a pair of blocks 31 mounted on top of the members 12 and 13 at the end of the boom and having mounted thereon, brackets 32 which are secured thereto by screws or bolts 33. These brackets 32 form bearings for a member 34 formed of rod-like material which passes therethrough and has its sides 35 bent downward at each side of the boom and formed at some distance below the same into a double loop 36. Depending between the members 12 and mounted at its upper end for swinging movement on the member 34 is a sheave carrying bracket 37 in which a sheave 38 is mounted for rotation. A rod 39 having a hook 40 at its upper end arranged to hook into the loop 36, extends vertically downward and has a hook 41 at its lower end adapted to hook into an eyebolt-42 pivotally mounted near the center of the platform. A sheave 43 is mounted for rotation in a swinging bracket 44 which is pivotally mounted near the eyebolt 42. Bracing rods 12 are secured in members 13 and extend longitudinally of members 12 and along the sides of block 13.

The loading member 13 is illustrated in Fig. 3. This device comprises a handle or controlling member 45 having a grip 46 formed on one end thereof. The other end of this handle is formed with an aperture which constitutes a bearing for an oscillating rod or member 47. This member extends transversely of the handle and, at its outer ends, is journaled in brackets 49 which are bent to converge and be secured to the handle 45 by bolts or rivets 46. The ends of member 47 project beyond the bracket 49 and have journaled thereon the. ends of a bent bail 50 which is formed with a loop 51 V at its upper central portion and in which loop a sheave housing 52 .is mounted for swiveling movement. comprising side members 53 and intermediate prongs or members 54 rests upon and is rigidly secured to. the pivoted or oscillating member 47. A strap member 55 ex tends under the fork and the prongs 53 and 54 are each rigidly secured thereto by staples 56 or by any other suitable means. The

ends of the strap member 55 project upvwardly at each side of the fork, as shown at 57, and a flat frame member 58 of general A forked structure 'of the fork. While, as illustrated, these ends are welded or integrally secured to the members 53, it will, of course, be understood that they may be secured thereto by screws, rivets, or any other suitable means. Vertical members 59 equally spaced at each side of the member 45, are rigidly secured to the rear of frame member 58 and the rear portion of the prongs of a fork. Nuts 60 are screwed onto the end of member 47 to retain the bail 50 in place.

Projecting from the top of the fork rearwardly and cent-rally thereof is a member 61' which is adapted to project into and be engaged by a yoke member 62 which is pivoted to the sides of member 45. A lug 63 projects above the yoke member 62 contrally thereof and rod 64 connects this lug of member 45 adjacent the ends of members The projection 61 constitutes a tripping tongue. When the fork is being used to carry material, it occupies the position shown in full lines in Fig. 3. In this position, the spring 66 holds the yoke 62in position to engage the tripping tongue 61. Vhen it is desired to trip the fork to discharge the load thereon, the handle lever 65 is pulled rearwardly. This swings the yoke 62 against the tension of spring 66 and disengages it from tongue 61. The weight of the fork then swin s it to the position shown in dotted lines in *ig. 3.

The method of using the loading device is illustrated in Fig.1. The cable C is arranged with oneend stationarily-secured in loop 27. This cable is then passed through the sheave 52 of the loading device, then over sheave 26 back between members 12, over sheave 29, then over sheave 38 and downwardly around sheave 42. At an intermediate point in the cable, beyond the sheave 43, the power means is disposed. In Fig. 1 this is shown as a tractor D. It will, of course, be understood that a horse or any other traction means may be used. From the power means the cable is passed over a sheave or pulley 68 which is secured to a stake, or other suitable fixed stationary member 69. From the sheave 69 the cable is led over a sheave or pulley 70 which'is also carried by some suitable fixed member 71. From the pulley 70, the cable passes to the loading device and is arranged to run upon sheave 67 thereon, and from this point, the cable passes to a fixed stake or member 72 and has its end fixed thereto in a stationary position. The movable pulley structure 17 will be anchored in a desired position to the eye-bolt 28 in the end of the boom by a section of cable 73. A wagon shown in Fig. 1 as E, or any other means which it is desired toload, will be placed in position under the projecting end of the boom.

The'braces 3 comprising sharpened iron bars will hold the device {A in proper posi tion.

The power means will now be moved in the direction of the arrow a'in Fig. 1. This will slacken the cable connected to the bail 50 of theload carrier B and the said carrier will be pulled backwardly by the portion of the cable passing over the sheaves 68 and 70. A load carrying device can now be brought into the desired position with respect to the hay, manure, stones, or other material which it is desired to load. When said member is suitably'disposed, the same will be held and guided by means of the handle 45. The power means is now moved in the direction of arrow 1), Fig. 1, and the loadca'rrying member B will be drawn along the ground until it arrives at a position substantially under the boom, when it will be elevated by the cable running over sheave 26 and be swung into position over the wagon E. WVhen in proper position, the fork will be tripped to discharge the ma terial carried thereon, into the. wagon E. The direction of movement of the power means will then be reversed and the operation repeated. It will be noted that the member 26 is capable of lateral swinging movement and that the boom member can also swing laterally to a considerable extent. The swinging movement of the beam is limited by its connection with the platform through member 39.

When it'is desired to take down the device, the bracing membersb, 7 and 8 will be unhooked from the eye-bolts at their lower end, and the member 39 will be, likewise, unhooked fromjthe member 42. The post 4 can now beswung downwardly upon the platform 1 and the boomxl-l removed therefrom by lifting-the pin 16 from its socket. All of the parts can now be laid upon the platform 1 and will occupy a comparatively small space. As the platform 1 is supported upon trucks, the device can readily be moved to any place where it is to be used.

It will thus be seen that applicant has provided a simple and eflicient loading device capable of a wide range of utility. The

device can be quickly taken down and trans- I ported from place to place and can be just as quickly set up for use.

It will, of course, be understood that the fixed members 69, 71 and 72 can be disposed in other positions than that, shown, and such-positlons will be determined by the requirements ofthe particular use to which the device is being put.

It may also be desirable to have a number of different types of load carrying members on hand which are adapted for. the different materials which it is desired to handle, any

one of which members can be used with the device atthe option of the operator.
