11 Claims. (01. 242ss "I'his invention relates to a hydraulic linoleum lifter ancl particularly to a crane-type device for lifting, conveying, displaying and dispensinglinoleum.

In storing, handling and displaying of linoleum, it is necessary to have a considerable men available to lift the heavy rolls injury to the linoleum because of breakage, chipping or other serious injury thereto.

The present invention provides a system havmeasuring the amount of and marking or scribing means so that t may be easily cut at the desired point. The linoleum lift according to the invention comprises a pair of end. stands separated by a telescoping reach member w1th each of the end stands being provided with a hydraulic jack or lifting device and means for oonneoting and disconnecting the stands from the ends of the roll of linoleum and also having rollers so that the entire device may be moved about at will.

It is an object of this invention to provide a linoleum lifting device.

It is another object of the invention to provide a linoleum lifter having hydraulic jacks or provding the lifting power.

It is a further object of this invention to provide a linoleum 1ifter whch will lift various sizes or lengths of linoleum rolls.

It is a further object of this invention to provdea linoleum lifter having an expanding mandrel for one end of the roll.

It is still further object of this invention to provide a linoleum lfter Which may be moved then anchored in place.

Other objects and many of the attendant advantages of this invention will be apparent from the followng detailed description taken in conjunction With the accompanying drawing, in which:

Figure 2 is a top plan view of one end of the Figure 3 is an end elevation of the lift with parts broken away and in section;

Figure 4 is an enlarged longitudinal section through the expanding mandrel taken substantially on the plane indicated by the line 3-4 of Figure 3;

Figure 5 is an enlarged cross section through the mandrel taken substantially on the plane indicated by the line 55 of Figure 4 Figure 6 is an enlarged cross section through the mandrel and taken substantially on the plane indicated by the line 6-6 of Figure 4;

Figure 7 is an enlarged detail of the auxiliary arm and mandrel for handling short rolls;

Figure 8 is a cross section showing the locking screw for the auxiliary arm and taken substan tially on the plane indicated by the line 88 of Figure 7;

Figure 9 is an enlarged cross section through the oastor showing the locking bail and taken 9-9 of Figure 1; Figure 10 is a meter together igure 11 is meter; and,

Figure 12 is a sectional elevation of the auxil iary mandrel for lifting rolls with a small core.

embodiment side elevation of the scriber and with the support therefor; an enlarged plan view of the Castor are swivelly mounted on the brackets 8 and '20, respectively, so that the platforms or end stands may be moved about as desired.

In order to look the end stands in position a braking bail 26 is mounted on the swivel bracket 28 on an axle 3 offset from the axle of the wheel 28 so that the bail 26 may be pressecl into tght engagement with the wheel i'i.

Each of the the ends of the sort of standard size of linoleum or when they are expanded to full length, they will extencl over and grasp the longer rolls of linoleum.

The stands 11! and 12 also each further include a hydraulic jack having a standard or housing 42 seeured to the base 16 by any suitable means such as Welding 44. The housing 42 extends in parallel relationship to the standard 32 and the sleeve 36 is provided with a gude 46 which embraces the housing 42 so that the sleeve 38 is non-rotatably mounted on the standard 32. In this marmer, the platforms 18 are maintained at transverse relation to the reach bar 14so that the standards 18 and 12 may pass closely adjacent to the ends of rolls of linoleum or other material lying on the floor.

Each of the hydraulic jacks 42 comprises in addition to the housing 42 a piston driving a piston rod 52 which has:a sheave 54 mounted at the top thereof. The piston 50 is operated by means of a pump"5 l operated by a handle 58 on which is placed a foot bail5tl sothatthehandle 58 may be conveniently operated by the oot of the operator.

The force of the jack 42 is transmittedto the sleeve 35 by means of a cable B2 having an eye 84 connecte to a hook 6'6 rigidly mounted en the side of the housing 42 and having an eye 58 connected to a hoek or eye "lil rigidly eonnected to the sleeve 35. Because of the entrainment eiect of the cable 62 over the sheave 54, the stroke of the piston rod 52 is doubled so that the stroke of the sleeve 35 is twice the stroke of the piston rod 52.

One of the standards, such 'as the standard 18 is provided with an expansible mandrel '15 mounted in a bracket 16 rigidly secureol to the sleeve 86 and having a threaded oore '18 provided with reversely direoted core threads 88 and 82. Floater bars 84 are provided with pivoted arms 85 and 88 which are respectivlyeonneeted to nuts 9o and 92. The sorew rod: '18 is maintained in the hearing block "15' by means of a locking collar8ii. The screw rod "18 is provided with a ratchet 84 Which is driven by a ratchet wheel 98 having a driving arm 98. The wheel 9e is provided with a pawl 1811 erossed by a spring 182 which may be reversed so that the arm 913 may be operated. in a singled-ireetion te rotate the screw '18-ineither of itsdirections. The ioater bars 84 are preventedrom rotation, operation of the handle willcause thenuts 80 and 82 te approaeh or recede rom each other depending upon the settingo the pawl 1118.

The opposite end of the stand -12 is provided. With a fixed mand-rel 110 Whichis preferably a wooden roller journaled on an axle 112. The axle H2 is pref-erably fixediy mounted in a braeket 114 corresponding to-the bracket 26.

In order to accommodate rolls of less length than the normal standard short length, an auxiliary arm 116 provided with a sleeve 1 18 is slidably mounted on the telescopingmember 38 and has provided at the lower end thereofwith a braeket i251 in whicli is mounted an axle 122 on which is mounted an auxiliarymanclrel 124 having an outer enlarg'e'd portion 125 and an inner reduced portion 128. The sleeve 118"is provided with an aperture 130 in which is adjusted a.setscrew 132.

A meter carrier is provided with a sleeve 1411 earrying an arm 142 havingan end bracket 144 in whieh is secured an axle 1415. A standard linear measure meter 148 hasthe opera-ting roll ti0n 1511 thereof journaled on the shaft 145. The arm 142 also earries the bleek 152 which has an aperture 15e in which is mounted a screw threaded rod 155 having a scriber point 158.

In order to make the lift adjustable to rolls having exceedingly small inner or internal diameter, an auxiliary mandrel 1511 (Figure 12) is provided With an internally serew threaded aperture 182 adapted to screw onto the end of the screw rod '18 so that a mandrel 0 small diameter will be available for attaching to rolls of small internal diameter.

'Ihe operation of the linoleum lifter is as follows: Move the lifter directly over the roll rom whieh yardage is to be out, having the jacks 32 aeein thedirection the linoleum is to be pulled out. Insert the floater bars 84 of the expanding mandrel, into the c0re of the linoleum leaving the 'ioater bars 84 exposed approximately two inches. With the ingers of one hand on one of thefloater bars 84, apply the hand: lever &&-in a cloelcwise direction until the .mandrel has expanded firmly against the core of the linoleum. With the hydraulio relief valve 1'18 at.the:base oi -the eylncler 565 closed, raise the linoleum to a olesired height. Now, insert the mandrel. 1111 on the opposite end of the lift into the-eoreof the linoleum, leaving approximately two inches exposed. Close the relief valv.e 1111 and r=aise the linoleum to a level height. Theliter. may then be moved forward to transport the roll. or tomove t.to a plaoewhere it isto:be:.displayed. After so doing step tlie foot brakes 26: firmly against the castors 24.

Slicle the measure meter 148 en the spaceribar 83 preferably about thr.ee .eet .from the edge of the roll en the side ofthe expanding;mandrel Set the meter at zero. Turn thesoriber blonk 152 so that the scriber point 158 isapproximately at right angle to the linoleum. Make certain the seriberpoint 1.58 is up ar enoughso .that it cannot scratch the surface of the linoleum. Revolve the roll sothat theedge of thewebwll be directly under the seriber point. Thenpush the linoleum over and down until the webvcomes rom the bottom side up. Zou mayttlrentstreteh the web about orprteferably roll =t up" asi.it is being dispensed. In either oase disperrse Japproxirnately two eet more than what isrequired. Then with the ratchet hand lever n98. wind the roll back until the meter registers exactly, never beyond the number of eet and inehesrequire'cli It is important to wind the roll back approximately two eet te avoidlooselaps from the roll in order to obtain an accurate scribe. Nowapply the serew brake on the shaft collar 1"1 4. Turn down the scriber point i513 so thatit-eompletely suspends the measure meter 1-48. Pull themeter assembly across the linoleum to seribe the surace With a out. Witlra feit base hoek knie out the linoleum on the soribeline. Make certain that the knife has smooth edges on the outer surfaee so that it will not markthe underneath web. After theeut has "been made, put the lift into position, release the relief valve anol slowly drop the roll into position.

When moving t'ne roll over thetop of other rolls' already in position on the display fl0or, suspend the roll on the lifter so that it hangs on each mandrel approximately two inches; 'This provides addecl side olearance so that the members 12 and l1i.may readilypass the end of rlls already on the floor.

.It will thus be seen that the presentinvenprovides a convenient means for lifting,

transporting and displayng linoleum as Well as for making a clean even out of the desired amount.
