Secured to the bottom their upper ends by longitudinal side beams of said platform near the corner adjacent said 8. The lower ends of the foremost of said rock-shaft and lever is a longitudinal block vertical beams are connected by a transverse 28, and secured at one end to the inner side of beam 4. The frame is of sufficient height said block and at its opposite end to said and width to allow a three-horse team to I rock-shaft 26 is a spring 29, the function of is elevated in the manner hereinafter deat its outer end with a bearing 30, in which is scribed. Said frame is mounted on a truck l journaled a pulley 31. Working laterally pass under a platform thereof when the same which will be shown. Said block is provided 1 1 othrough the outer part of said bearing is the inner eyed end of a transverse cont-rollingrod 32, the outer free end of which works through a corresponding lateral perforation in the adjacent side beam 17 of said platform 14 and is adapted to engage the under side of said lever 2 7. Said controlling-rod 32 is provided with a coil-spring 33 and has secured in its inner eyed end one end of a cord or rope 34, which works over said pulley 31. Hinged at their outer ends to the inner faces of said side beams 17, near their rear ends, are plates 35, and secured to the inner perforated ends of said plates are the ends of snort ropes or cables 36, bent in the form of loops, which i are adapted to hook over pins 37, extending upward from the periphery of said ro'cleshaft 26. Secured to the ends of the foremost of said trap-doors, near its inner side, by staples 38 or other equivalent means are the inner ends of chains 39. Said chains pass up over said pulleys 20, journal'ed near the inner faces of said side beams 17 of the platform, thence downward under said pulleys 22, journaled to the ends of said door 16, thence upward over pulleys 24, journaled to the under sides of said side beams 17, thence horizontally rearward between said plates 35 and guide wires or bars 40, two secured around and near each end of the rearmost of said transverse rods 25 at their inner turned e1;ds and hooked over the tops of bearings 41, secured to the under faces of said side beams 17 near their rear ends, and thence upward and are wound around a transverse shaft 42, journaled in bearings 43, secured to the rear edges of the innermost of said vertical beams 2. Said shaft is provided'at its front end with a ratchet 44. Said ratchet is controlled by a dog 45, fulcrumed at its inner end to the outer side of the adjacent vertical beam 2. A crank of any suitable construction may be employed to put said shaft 42 in rotation, when the chains wind around said shaft and operate to close the trap- doors 15 and 16. The operator then pulls down on the free end of said lever 27, which effects a partial rotation of said rock-shaft- 26, causing the cords or ropes 36 to wind around same and throw the said clutches in engagement with said chains 39, which prevent said chains from slipping back or forth. Before throwing the free end of said lever 27 down to its lowest posiim it is necessary that the operator pull on the free end of said rope or cord 34 and draw the controlling-rod 32 inward out of tlie path of the lever. When the free end of the lever is thrown down to its lowest capacity, the operator releases the cord orrope 34, when the contraction of said coilsprir,g 33, secured around said controlling-rod 32, throws the same outward in its normal position, its outer end engaging with the upper side of said lever, holding it in its last position.

To open the trap-doors, the operator pulls on the free end of said rope 34, which releases the outer end of said controlling-rod 32 from engagement with said lever 27, when the action 01' said spring 29 effects a partial l rotation of said rock-shaft 26, releasing the rclutches 35, through the medium ol said said short ropes or cables 36, from engagement with said chains 39, the weight of said trap-doors causing them to open. Said platform 14 is provided on its upper lace, near its rear side, with a dash 46. Said platform 14 is raised or lowered by means of four chains 47, two of which are secured to staples 48, secured in the upper laces and near the front ends of said side beams 17, pass upward over pulleys 49, journaled in suitable bearing 50, secured on the tops and near the ends of the foremost of two or more transverse strengthening-beams 51, secured on the tops and near the ends of said longitudinal beams 3, thence horizontally rearward over pulleys 52, journaled in suitable bearings 53, secured on the top and near the ends of the rearmost of said transverse bracebeams 51, and thence downward and wind around a main shaft 54, journaled near its ends in bearings 55, secured to the outer edges and near the lower ends of the rearmost of said vertical beams 2 and near its central part in bearings 56, secured to the outer edges and near the lower ends of two central vertical braces 57, secured at their lower ends to said rear axle 5 and at their upper ends to the rearmost of said transverse strengthening-beams 51. The other two chains are secured at their inner ends to staples 58, secured in the upper faces and near the rear ends of said side beams 17, pass upward over pulleys 59, journaled in suitable bearings 60, secured on the top and rearmost of said transverse strengtheningbeams 51, inward and adjacent said bearings 53, and thence downward and also wind, around said main shaft 54. Horizontal rods 61, terminating in forks 62 at their rear ends, are secured at their front ends to the tops of said bearings 50, secured to the top of I l the foremost of said transverse strengtheningbeams 51 and at their forked tops of adjacent bearings 53 and 60, secured to the top of the rearmost of said bracebeams 51. Said main shaft 54 is provided intermediate of its length and between said vertical braces 57 with a circular enlarge ment or drum 63, to which is secured one end of a draft rope or cable 64, adapted to wind and unwind around said drum. \Vheu in use, the said draft rope or cable works between a guide, which preferably consists of two vertical rollers 65, secured nearly I contiguous between the outer ends of l curved bars 66, secured at their inner ends l to the outer sides of said vertical braces 57. Said main shaft 54 is provided near its front end with a ratchet 67, adapted to be engaged ends to the adjustably secured to by a dog 68, fulcrumed at its inner end to l the outer side of the adjacent vertical beam l of said beams 2. Vertical plates 69, provided with elongated perforations 70, are the inner edges of said vertical beams 2. They are lowered to the ground when the machine is in operation and serve to anchor the machine and hold the platform 14 in position. It will be obvious that said elongated perforations or slots facilitate the raising or lowering of the plates. Secured in the outer sides of said vertical beams 2, immediately under and in parallel apposition with said side beams 3, are longitudinal beams 71, and secured vertically to said beams 3 and 71 are bearings 72, in the lower ends of which are journaled horizontal rock-rods 73, one of which termi nates at its extreme rear end in an eyed arm 74 and the other in a handle 75, carrying an integral inwardly-extending eyed arm 76. Secured at its ends in the eyes of said eyed arms 74 and 76 of said horizontal rock-rods 73 is an oblique transverse connecting-rod 77. Said rod 77 is provided with an eyed extension 78, in which is secured one end of a coil-spring 79, secured at its opposite end to the outer edge of the adjacent vertical beam 2. Said rock-rods 73 are provided near their ends with vertical links 80, which are secured at their lower ends between the sides and near the outer ends of transverse guard-dogs 81, having secured between their their sides and near their inner ends the lower ends of substantially vertical connect ing-rods 82, suspended at their upper ends from supports 83 in the nature of rods bent partially around said longitudinal beams 3. Said connecting-rods 82 are suspended from said supports in such a manner that their lower ends are susceptible of oscillation, the purpose of which will be shown. hen in its normal position the free end of the handle 75 engages with a horizontal rearwardlyextending catch 84 of a transverse plate 85, secured to the outer edge of the beam of said vertical beams 2 adjacent said handle. In this position the guard-dogs 81 are thrown outward sufficiently (see dotted lines, Fig. 5) to admit the passage of the platform 14 when hoisted. The free end of the handle 75 is then released from its engagement with said catch 84, when the action of said spring 79, through the medium of said transverse oblique connecting-rod 77 and said horizontal rock-rods 73, operates to throw said guard-dogs 81 inward, the inner ends of which engage with the under side of said platform 14 and dropping of the same.

My invention is a so equipped at its rear end with a rope or cable 86, which is secured to and wound around said main shaft 54 at one end, passes upward over a pulley 87, removably secured in guard against accidental the rear end of a rear wardly-extending support 88, secured at its inner end to the rear end of the machine in any desired manner, and has secured to its opposite end abucket 89 of ordinary construction loaded with re ck or some other heavy material. The bucket of rock or other material serves to partly counterbalance the weight of the platform, so that when the same is unloaded and allowed to descend to the ground it will do so with a predetermined and uniform velocity. A tread-lever 90 is fulcrumed at its inner end. to said rear axle 5 and is pro-' vided with a chain 91., which is secured to said axle immediately above the inner end of said lever, passes over a pulley 92, rigidly connected to said main shaft 54 near its front end, and is secured to said lever at its free end.

Said machine is also preferably equipped at each upper corner with an oblique brace 95, which are secured at their upper ends to the outer sides of said side beams 3 and at their lower ends to the outer sides of saidvertical beams 2 and at its rear lower part with oblique braces 96, which are secured at their lower ends to the upper face of said rear axle 5 and at their upper ends to the inner sides of the rearmost of said vertical beams 2.

The operation of my device is as follows: The machine is placed where there is material to be hoisted and the reaches 12 removed. The platform is then lowered to the ground to receive the material to be hoisted, which may be drawn on the platform by scrapers of any desired construction. When the platform is sufficiently loaded, the main shaft 54 is put in rotation by a crank or other equivalent means. When the machine is operated without horse-power, a team is hitched to the free end of said draft-rope 64, secured to said drum 63, and draws away from the machine, which operation effects the rotation of said main shaft and elevates the platform. When the platform is raised to the proper height, the ratchet 67, secured on the front en of said shaft, and dog 68 are thrown in engagement and hold the main shaft against reverse rotation and consequent dropping of the platform. To further guard against the dropping of the platform, the guard-dogs 81 may be thrown in engagement with the under side of the platform in the manner above described. The vehicle to receive the load is then driven under the platform, when the trap-doors are opened and the load dropped. The doors are then looked again and the guard dogs thrown out of engagement with the platform, when the same is permitted to descend to the ground with a velocity controlled by the bucket 89 and its lo ad. Should the operator desire the platform to descend to the ground at a slower velocity than usual when attained "hrough the agency of the loaded bucket 89, rope or cable 86, and pulley 87, the tread-lever may be employed.
