9 Claims.

This invention relates generally to a portable elevator and hoist which is particularly adapted for elevating and transmitting building materials to workmen engaged in constructing a building. Heretofore it been customary to erect a scaffold adjacent the building, which includes an elevator which is either manually or power operated to lift and transfer building materials to the level at which the workmen are working. lhe building material usually includes such things as steel, lumber, hardware, piping, electrical fix vtures, bricks, mortar, cement and other material such as plumbing and electrical fixtures and the like. Such practice has proven costly and impractical because the workmen necessarily have to move about different areas of the building to perform their Work,

I have invented and designed. a portable elevator and hoist which is mounted on wheels so as to be readily and easily moved about and around the building in order to deliver the building materials to a point adjacent the workmen which will result in a great saving in time, labor and expense.

My improved. apparatus consists essentially of a base frame member which is mounted on wheels so as to be readily moved around to different sides of the building with a minimum effort so that a considerable saving is accomplished.

One of the main objects of my invention is to provide a portable electric elevator and hoist which can lift and transfer building material to workmen constructing a building which will result in a great saving in time and labor and which at the sametime is practical and well adapted for production at a minimum cost and which can also be moved to other buildings and used again and again.

Another object of the invention is to provide a combination elevator and hoist which can be used to transfer and to lift large and bulky building materials such as steel, pipe, bricks and other like materials, and which also can be used to lift a cement or mortar bucket which is automatically tipped and dumped when it reaches the desired predetermined elevation.

A further object of the invention is to provide an elevator and hoist which is portable and self contained and which has a pair of carriage guides which are made in a plurality of sections and to which additional sections may be added as the construction proceeds, such carriage guides being preferably formed of I-beams which serve to support and to guide the elevator, the elevator comprising a platform of sufficient size and area as to transport both b1 ,2 building materials and a or mortar be. act which is automatically when the 5; me reaches a certain predetermined level. When it is desired to transport only heavy, bulky and large materials, the e nt bucket may be readily removed and the cut: elevator platform. used for that purpose.

A. still further object of the invention is to provide a combination elevator and hoist having the above described distinguishing features and characteristics which is well adapted for quantity production at a low cost.

Further and more limited objects of the invention will appear as the description proceeds and by reference to the accompanying drawings in which:

Figure 1 is a perspective view of the preferred embodiment of my improved portable elevator and hoist.

Figure 2 is a fragmentary view in front elevation the upper end of the elevator and showing the dump bucket in its tilted or dumping pc on.

igure '7 is a top plan View of the base frame of the apparatus and Figure 8 is a vertical sectional view taken on line l-3 of Figure '7. erring now to the drawings, particularly Fig-Lu es 1 and 7; the apparatus comprises a base -..e member which is generally rectangular 1 shape a d consists of side members 1 and 2 .eces El and t. Extending transversely the are reinforcing bars 5 and 6 which .terl together by angle bars I and 8. at either side of the frame are a pair ill on which are mounted wheels D. os of axles 33 l. H and l to the front end of the frame are a of angle bars as and M which are welded at .e end to the frame members i and 2 and to other ti outer ends. The reference "actor designates a ring by means of which chm. the vehicle. may be attached to another vehicle so as to be towed. Welded to the front end of the frame are a pair of vertically disposed angle irons i6 and I! which serve to reinforce the structure. Arranged at each side of the frame and extending vertically upward therefrom are a pair of I-beams I8 and I9. All of the members which form the base frame are formed of steel channels or angle irons which are welded in place. Secured to the upper ends of the angle irons I6 and I! are a pair of reinforcing angle irons 29 and 2|, the opposite ends of which are welded to the I-beams I9 and I8, respectively. Also secured to the angle irons I6 and I1 are a pair of reinforcing angle irons 22 and 23, the opposite ends of which are welded to the I-beams l9 and I8, respectively. Secured to the angle irons 22 and 23 are a pair of angle bars 24 and 25, the opposite ends of which are secured to reinforcing bars 26 and 21 and the opposite ends of which are welded to the I-beams I9 and I8, respectively.

The reference characters 23, 29, 39, 3|, 32, 33, and 34, designate additional reinforcing angle bars which serve to reinforce the entire structure. The I-beams I8 and I9 are made up of a plurality of sections which are secured together by splice plates 35. The upper ends of the I- beams I8 and I9 are connected together by a cross bar 35 which preferably is in the form of a channel.

Disposed between and slidably mounted with respect to the I-beams l8 and I9 is a slide or carriage indicated generally by the reference character 3]. This slide is made up of a pair of longitudinally extending channels 38 and 39, connected together at their opposite ends by channels All and 40a. The reference character 42 designates additional reinforcing bars. Carried by each of the bars 38 and 39 and disposed at opposite sides thereof are a pair of rollers M which fit neatly within the I-beams, shown most clearly in Figures 2 and 3. Also carried by the channels 38 and 39 are a pair of rollers 4Ia which also engage within the I-beams l3 and I9, as will appear most clearly from Figure 2. The slide or carriage is also provided at its lower end with rollers similar to the rollers 4| and Ma which also fit within the I-beams l8 and I9.

Carried by the carriage slide 3! is an elevator platform which comprises a pair of horizontally disposed channels 43 and 44 which are connected together at their outer ends by a reinforced channel 45. The inner ends of the channel 43 and 44 are welded to the slide. The reference characters 46 and 41 designate additional reinforcing channels which are welded to the channels 43 and 44, respectively at their outer ends and to the slide 3'! at their inner ends. The reference character 48 designates additional reinforcing members which serve to strengthen the elevator platform.

Extending transversely of the platform and bolted thereto are a pair of channels 49 and 50 on which is pivotally secured the dumping bucket which is supported by an axle 52 journaled in brackets which are secured to the channel members 49 and 50. Pivotally secured on one side of the bucket 5I is a dumping dog 53. Also secured to the same side of the bucket 5! is a stop pin 54 which is disposed adjacent one end of the dumping dog 53, and overlies the same, as will appear most clearly from Figure 4.

Slidably and adj ustably mounted on the I-beam I8 is a U-shaped yoke 55 which is secured in the adjusted position by set screws 56. Carried by the yoke 55 is a shaft 51 on which is mounted a roller 58, the purpose of which will hereinafter appear.

The reference character 59 designates a spring, one end of which is secured to the lower end of the dump bucket and the other end of which is secured to the elevator platform, the purpose of which is to return the dump bucket to its normal position after it has been emptied. Disposed between the bars 20 and 2| is a pulley 69 and journaled on the top of the channel 36 is a pulley 6!. The reference character 62 designates a rope, one end of which is connected to the carriage slide 39. The rope extends over the pulley BI and thence downwardly over the pulley 60, and is connected with the hoist indicated by the reference character 63. The hoist 63 and the mechanism for driving it are of conventional construction and form no part of this invention. The reference character 64 designates a prop which supports the front end of the apparatus when it is in use.

It will be noted from an inspection of Figure 1 that the dump bucket is detachably secured to the elevator platform and. is disposed at one side thereof.

When it, is desired to use the apparatus, it is moved to a point closely adjacent the building being repaired or constructed. As hereinbefore explained, th frame of the machine is made-up of a plurality of sections. The height to which the materials are to be lifted determines the number of sections to be used. The elevator platform is moved to its lowermost position and the dump bucket is filled with mortar, cement or other material to be lifted. The elevator platform is then moved upwardly by means of the hoist. The yoke 55 is adjusted to a position on the I-beam I8 where it is desired to have the bucket dumped and is locked in place by the set screws 56. The roller 58 projects outwardly in direct vertical line with and overhangs th dumping dog 53. When the bucket is elevated, the dumping dog reaches a point where it is engaged by the roller 58 which moves the dumping dog to the position, shown most clearly in Figure 4, in which position, one end of the dumping dog 53 is in engagement with the stop pin 54. The upward movement of the elevator platform causes the bucket to move to the position, shown in Figure 4. When the bucket has been emptied, the spring 59 serves to return it to its normal position. Should the elevator platform be accidentally moved too high, the roller 58 will roll off of the end of the dumping dog and no harm will be done as the dumping dog is pivotally secured to the side of the bucket. Should it be desired to use the elevator to move heavy or bulky materials or to make use of the entire elevator platform, the bucket 5| may be readily removed. It will thus be seen that the apparatus can be used to lift either mortar or cement or similar materials or to lift heavy or bulky materials, such as steel, lumber or other materials.

It will now be clear that I have provided a combination elevator and hoist which will accomplish the objects of the invention as hereinbefore stated. Various changes may be made in the details of construction and arrangement of parts without departing from the spirit of the invention. The embodiment of the invention herein disclosed and described is, therefore, to be considered merely as illustrative and not in a limiting sense as the invention is limited only in accordance with the scope of appended claims.
