'len th thereof, for strengthening the same from each other.

with two forwardly-promoting ears 14, hav- Patented July 24, 1906.

(I views, the numeral 1 designates a base constructed, preferably, of angle-iron bent, preferably, into a Ushape, the open end being located at the front; of the machine,-and 2 designates a transverse brace secured across the base-frame, preferably midway of the an holding the sides thereof in a proper po-. sition.

Secured within the frame and between the rear end thereof and the cross bar or brace 2 are spaced longitudinal bars 3 and 4, and between these bars and adjacent the cross-bar 2 are arranged two vertical standards 5 and 6,

which are constructed of channel-iron so arranged that theirchanneled faces are adjacent each other and with their ed es spaced These standard s are supported by the bars 2, 3, and 4 and the braces 7, which are bolted or otherwise secured at one end thereto, and the other end is secured to the top of the side bars of the base-frame 1. Journaled across the top of and between thestandards 5 and 6 in suitable bearings is a pulley-wheel 8, and 9 designates bands secured to and extending across the tops of the standards to serve as braces and securing means for the tops thereof and as guides for the elevatin rope or cable.

A carrierame 10is adapted to move between the standards 5' and 6 and is provided with rearwardly-projecting bearings 11 at the to and bottom thereof, and journaled in these bearings 11 are suitable axles carrying antifriction-pulleys 12, each of which is provided with a ta ering peri hery and a flange 13, and lsaidpu leys are a apted to travel in the channels of standards, so that the face of the flanges 13 will engage and bear a ainst the edges of the channels in said standards. This carrier-frame is preferably provideding vertically-alined aperturesfor a purposeset forth.

The numeral 15 designates the side bars of a movable platform, which are preferably spaced and held apart by means of a connect in cross-bar 16.

cured to the side and at a point to ensage the cross-bar 16 are uprights 17 of any esired height, and connecting the up r ends 'of these uprights is another crossar 18. This platform may be constructed of any desired material, preferably angle-iron, suitably braced and fastened, and 19 designates corner-plates secured at the base of the uprights 17 and to the side bars 15.

Secured to the bars 16 and \18 are rear- 'wardl -projecting brackets 20, which are and 21 and 22 are bolts or pintles passing through the registering apertures to form a vertical pivot for the platform and are held in position in any suitable manner, preferably by means of nuts 23, engaging the lower threaded ends thereof.- The upper bolt or pintle 21 is preferably provided with an eye 24, through which passes the end of a rope or cable 25, which is secured in any desired manner and which passes beneath the guides 9, over the pulley 8 at the upper end of the standards 5 and 6, and down to and around a drum or Windlass 26, which is provided with a car 27. Said drum is journaled in'suitab

e bearings

28 and 29, secured, respectively, to the standards 5 and 6 and. to a support 30, the lower end of which is secured to the'lyase-frame 1, and the upper end is held in proper osition by means of a bar or brace 31, exten' ing therefrom to the standards 5 and 6.

A shaft 32, provided with a gear 33 and crank 34, -is journale'd in suitable bearings carried by the standards 5 and 6 and support 30, 'andsaid gear meshes with the gear 27,

through the medium of which the drum 26 is revolved to windthe cable 25 thereon, and thereby raise or lower the platform.

A band-brake 35, provided with an operating-handle 36 and cooperating with a pulley 37, all of the ordinary construction, may be rovided to regulate the speed and to assist in holdin' the latform at any desired height.

Secure to t e front of the base-frame are castei's 38 of any desired construction, and 39 is 'a' caster journaled at the rear of the frame in a pivotal bearing 40, and is a handle'secured to the bearing and is adapted to raise the caster 39 from the floor to permit the feet or legs 51, which-are secured to the rear of the base-frame, to rest upon the floorwhen the handle 50 is raised to turn the bearing 40 and caster 39 about its journal or pivot 52. When the handle 50 is lowered, the caster 39 will'raise the feet 51 and theelevator may be trans orted to any desired place by means of said handle.

Suitable skids 53 are pivoted, as at 54,- to the front of the side bars of the baselrame 1, and said skids-are adapted to be turned back on t'heir pivots out of uthe way to permit transportation and into sucha position that they will rest upon and be supported by means of the radial projecting lugs or pins 55, carried by thebase-frame 1.

If desired, and in order to further brace and support the standards 5 and 6, connection or gusset plates 56 may be secured to the lower portion of the standards and the bars 3 and 4.

In use the elevator is transported to the desired place, the handle 50 raised to the position shown in Fi 1, when the machine will be lowered and al owed to rest upon the feet or le S 51, which will prevent the frame from accidentally moving; The skids 53 are then turned upon their pivots 54, so that the forward ends will rest upon the ground or floor, forming an incline up whichthe barrel may be rolled and onto the arms or bars'15 of the platform when the latter are at their lowest point and flush with the top of the sides-of the base-frame. The crank 34 is thenturned,

transmitting motion to the drum 26, which winds up the cable or rope 25 and raises the platform with the barrel thereon to the proper height, at which point it may be held y the' brake 35. In order to prevent the barrel from rolling off of the arms 15, the front ends thereof are. preferably turned sli htly u ward, as at'57, to form stops.

en t ebarrel is in its elevated position, and if desired, or if it should be necessary to discharge the barrel therefrom at an an is in order to lproperly lace the sameupon t e pile or stac or to de iver it onto a conveyer,

the platform may be swun about the V61:

eys 12 W1 1 form bearings and serve to re uce the friction, their onl point of contact with the standards being t e engagement of their peripheries and the flanges 13 with the edges and the inner faces of the channels formed in the standards 5 and 6.

It will also be seen that with an elevator thus constructed the platform will be permitted to be lowered entirely to the ground and. within the base-frame, as the carrier and .guiding-frame-are eompletel protected and will not contact with any of t e braces or supports throughout its entire path of movement.

If desired, and'in order to prevent the plg-tform from'swingi about its pivot unti the desired height has con reached and to hold the same in position; there is provided ajlooking device. Any-suitable device may beemplayed for this'purpose; beta-simple and efective form is'to provide a notch or recess (or series of notches) 14" in one of the ears 14 and a coacting lug or projection carried by the adjacent face of the bracket 2'0, which is adapted to enter the recess 14. Said notch and projection are of such a shape as to firmly hold the platform in the-proper osition and yet permit the same to become disengaged when a reasonable strain is exerted thereon to turn the platform.

It is to be understood that it is not desired to be limited to the exact sizes, proportions,

materials, arrangement, and construction of the several arts, as numerous changes may be made wit out departingfrom the spirit of the invention.
