To all wit-m it may concern.
Be it known that I, JULES-151. NY, a citizen of the United States, residing at Berkeley,
in the county of Alameda and Statefof Cali# fornia, have invented a new and useful Improvement'in Processes 'and'Apparatus Vfor Covering Lithograph Rolls, ofvwhich the following is a specification. f k"This invention relates to a process .of and anapparat'us for covering lithographrolls.
It" is the principal .object offthe present invention to provide an apparatus by which Y which:
skins may-be drawnover and pulled oflof lithograph rolls in a continuous operation ata uniform pressure, thus insuring that the roll will be. smoothly and rapidly covered.
i AThe presentA invention contemplates the use of a iixedmandril onto'which a lithograph roll is positioned, said mandril being equipped with power. means. for engaging a collar detachably secured to :the skin of a lithograph roll and byfwhich means the roll may `be pulled ontov the lithographl roll o r jremoved therefrom. Y.
The invention isv illustrated byJway of example in theaccompanying drawings,.in
Figure 1 is a view in side elevation illus-v trating the principal parts of the .presentinvention broken away for the sake ofconvenience. f
Fig. 2 is a view in side elevation showing the opposite side of the apparatus,
. Figi, 3 is an. enlarged fragmentary view disclosing the gripping action of the collar. y
mandril extends horizontally and parallelto the shaft 13 and is rigidly secured in the face of a pressure block 17. This block is formed integral with the standard 12 and extends vertically therefrom. Bearing plates 18 are formed integral with the standard l2 and provide bearings 19, 20 and 21 have shafts 22, 23 and 24. The shaft 22 is uppermost and extends transversely of the longitudinal specicanon f Letters latent.V

endof shaft f y23 vand may. rotate fwith this shaft as actuated bythe operating crank-l 31*- The shaft 24s;. provided to' receive idler rollers 82 over A`which fthesprocket ichains 27 ma-y extend and by which rollers ,the sprocket chains are maintained constant meshwith the sprockets 25.; l y. j The collar structure; `28 Y is-more clearly shown in-fFig 3-and .comprises an inner sleeveBB and an louter sleeve 34 telescoping thereover. The adjacent faces @f -lthese sleeves are tapered so thatthesleeve 3 3 may slip within the sleevet yand become :wedged into position; A gpluralityof circumferen tially extending corrugations 35 are formed around thetapered portion of the sleeve 33 a wall of the .roller skin Sfte grip this skin.

In carrying out the present invention a lithograph roll which has. a mandrel 16 formed integral therewith or,r otherwise per.-v
manently secured thereto" isset up; in -the machine withone end vof the mandrel engaging thepressureblock17, the opposite end of the roll'beingsupnmted bythe member ll- Y 1f it iS desired t0 removthe Q l'dskiri, :tlie'collar Structure .28 is clamped thema. Pulling .actiongiSr-hell transmitted .to the@ Hary strut:
of the sprocket chains 27 after which these chains may be drawn by Operation. 0f the gears 26 and 30 through4 movement of the crank 31. This action will gradually and continuously pull the skin over the roll and to a seated position as shown in Fig. 2.. Then the skin has been tightly drawn into place a two part clamping collar 37 may be secured around the roll to clamp the skin at a point near the forward or at the opened end thereof. It is then desirable to remove the hooks from the pins upon sleeve 34; and place them upon pins 39 of the inner sleeve 33. ByV further drawing upon this sleeve the f collar member may be removed from its enand around the skin and drawn longitudinally thereof by the chains 27, the hooks of which engage suitable pins carried by the collar. It will be understood that during the operations described the roll will be supported by the member 14; at its outer end.
It will thus be seen that by the present simple and inexpensive machine, lithograph rollers may be rapidly covered or uncovered and when covered the skin Will be tightly stretched and smoothly drawn over the surface of the roller by continuous'and direct operation.
1 lVhile I have shown the preferred form of myinvention as now known to me, it will be understood that various changes in the construction, combination and arrangement of parts may be made by those skilled in the art without 'departing from the spirit of the invention as claimed.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
' 1. A method of' covering'lithograph rolls which consists of gripping one end of the lithograph roll skin and drawing it over the roll vin. a continuous operation, thereafter clamping the skin to prevent shrinkage during which time the clamping means may lbe removed andthen sewing the skin around the end of the mandril to maintain it in its stretched condition.
4f. A device of the character described comprising a base, a horizontally extending mandril secured by one end to ythe base and adapted to receive a lithograph roll, a clamping collar for engaging a lithograph roll cover and power means acting to pull'upon said cover clamp to drawthe cover onto the roll.
5. A device of the character described, co1nprising a base, a horizontally extending mandril secured by one end yto the base and@V adapted to receive a lithograph roll, a clamping collar for engaging a lithograph roll cover and power means acting to pull kupon said cover clamp to draw the cover onto the roll, and means for releasing said clamp from the cover.
6. A device of the character described, comprising a base, a horizontally extending mandril secured by one end to thebase and adapted to receive a lithograph n roll, a
clamping collar for engaging a lithograph roll cover and power means acting to pull upon said cover clamp to draw the cover onto the roll, and means for releasing said clamp from the cover, and means for holding the cover in its stretched position over `the roll while the clamp is released and the cover secured in position.
7. A device of the character described comprising a main frame, a horizontally extend'- ing Ymandril secured by one end to the main frame and adapted to receive a lithograph roll, a supporting member adjustably disposed relative to the mandril for the support of the lithograph roll at the free end of the mandril.
