'service' and a general I To all whomrz't 'may concern. Be 1t known that I, THOMAS CAMPFIELD, aV

citizen of the United States, residing at Unity, in the county ofy Alexander, State of Illinois, have invented certain new and usey ful Improvements in Portable Elevators;

andI do hereby declare the following to be a full, clear, yand exact description of the .in-

1 vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to elevators, particularly to manually operated elevators'for stores and similar places, and has for its object the provision of a novel elevator which maybe moved `from place to place for use and which isspecially adapted for the elevating of cakes of ice from the floor to the ice receiving door of the type of large refrigerators used in stores, Vbutcher shops, markets and other places. c

An important object of the invention is i the provision of an elevator of this character which is `provided with means where# by it will be held'iirmly upon the floor while in use so that it cannot shake or be displaced while cakes of ice dragged onto or off from it.

Arfurther object is the provision of a device of this character provided with roller carrying members whereby it .may be readily draggedA from place to place, the roller carrying p members being capable of` being swungso that the frameof the device will are being rest directly upon the floor to insure its remaining stationary. n l

lStill another and more specific object is the provision of the device of this character having means engageable with the ceiling or a beam n secured upon a refrigerator whereby the device may beadditionally held against displacement. I 'i An additional object is the' provision r'of a device of thischaracter which will be simpleY and efficient in operation, durable 'in improvement of the art. Y

lVith theseand other objects `and advantages in view, the invention consists Yingthe rnovel construction, arrangement and combination of parts as will be hereinafter more vfully describedfand claimed, and illustrated in the accompanying drawing, in which- Figure 1 isa sideelevationl ofrmyidevice in positionready for use, Fig. 2 is a similar view ofthe opposlte side, F 1g. 3 is -afront SpecificationV of Letters Patent.

elevation,Fig. l is a cross sectional view on the line tf1 of F ig.V 1, Fig. is a top plan View', Fig. 6 .is n

through the lower portion of the device showing the roller carrying members swung so as to support the device upon the rollers, and Fig. l modified means for holding the device stationary.` Referring more particularly to the drawing, the lnumeral 1() designates front uprights which are spaced from and parallel with similar rear uprights 11. The uprightsl() and 11 are connected and supported at their upper ends by cross bars 12 and 13 which are suitably braced as shown.V

sition, the bottom 18 is disposed upon the cross bars 14 and 15 and alines with an inclined guidemember 20 hinged upon the forward cross bar 15 as shown at 21.

In order that the elevator member may be raised and lowered, I provide a mandrel 22 journaled .in brackets 23 secured upon the forward uprights 10 and provided upon its end with a gear 241. A cable 25 has one end secured to the mandrel 23 and extends upwardly and over a pair of rollers 26 journaled in bars 27 secured across the top cross bars 12, and has its other end secured to the top 17 of the elevator member as shown at 28. A shaft 29 is journaled on the bracket 23 and is provided upon one-end with an operating handle 30 and has secured thereon a. pinion 31 meshing with the gear 24. It will be seen that when the shaft 29 is rotated by the handle 30 the mandrel 22 will be turned and the elevator member raised within the frame` formed by the uprights.

In order that the elevator membeiniay be held at any desired position, I preferably provide nieansr for locking the mandrel againstrotation, which means may conveniently be a ratchet 32 secured upon the shaft 29 and engageable by a pivoted pawl 33 upon the adjacent upright 10.

i VIn order that my device may be ported conveniently from place to place, I

provide members 34 hinged, as at 35, `upon the cross bars 14 at the bottom of theframe@ 1 adjacent the free be disposed vertically beneath `the cross barsl4.V i y When it isjdesir'ed to adapt my device'for use, so that the rollers 36 will not engage through `bearings the -floor, the members are' Vswung -upwardly and outwardly assho'wn 1n Figs. l,

3S secured upon the cross bars I4.' The `rod -37iis provided at one end with an'operating lever 39 by ',whichit may be rocked. Crank arms the rod 37 and have theirhorizontal portions 441 extending through rings/42 'pivot-v allyvsecured upon the members 34. The de vice being in the position shown in Fig.l 6,

with the rollers 36 engaging the floor', rock-i 39 to either side will cause the ing the lever cranks to move upwardly, 'thereby swinging the members 34 upwardly and al-4 lowing the lowerends 'of the uprights 10.v and llto rest upon the door.

The use of my device isas follows. r V*After Y the device has been'mov'ed, as byfdragging elevator and into it upon its rollers to the ice box" or other place are swungiupwa'rdly, as described, s o that the device will rest with its uprights engag-V ing the floor. The elevator member being in its lowest position, cakes oii'ice or the like arevslid up the guide member 20'and on to the bottom' 18 of the elevator. p by turning the handle 30, the cable 25 will be wound upon the mandrel 22 and the elevator member will be raised to the 'desired position. lThe cakes of ice :or the like may then be the refrigerator or other place where they are desired. i

In'order that the device may' be held rigidly. in place and prevented lfromlwabblingor shaking I provide avertically eX- tending bar 43 slidablewithin guides 44 secured Vuponoross 'bars 45 connecting two of the sideuprights. Thebar 43 may be slid upwardly intoa slot 46 formed in aV member 4 Y `of the room or building in which the device is usedsk A pin or boltf48 may thenfbe in-` serted within the proper one of aseries of apertures 49 formed in the bar 43.*so that itV Vwill engage the top face of thelowermost guidel 44L for preventing the rod 43' from slipping out of the slot 46.7' The bar "43 is prevented from slipping- 44 by a lug 50.-.
