THOMAS P. LITTLE, OF CHICOPEE FALLS, MASSACHUSETTS, ASSIGNOR TO THE FISK RUBBER COMPANY, OF CHICOPEE FALLS, MASSACHUSETTS, A. CORPORATION OF MASSACHUSETTS.
GUIBE FQR CALENDERS.
Application filed .Tune 25,
To all whom it may concern Be it known that I, THOMAS P. LITTLE, a citizen of the United States of America, residing at Chicopee Falls, in the: county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Guides for Calenders, of which v in'gs in which- Figure 1 is a vertical section through a calender showing one of my improved es;
- Fig. 2 is an end view of the deflector portion of my improved guide;
Fig. 3 is. a side view thereof;
tie a detailshowing the method of attachment of the deflector to the body pert of the guide; and
i Fig. 5 is a detail of a portion of a bracket which' supp'orts both the deflector and the end pieces'of the guides.
,The calender'rol s 10, 11 and 12 are of the usual type, carried between end frames 13 and working a sheet '15. In orderto prevent the bank of rubber-working out beyond the end of the rolls it is customary to provide a wedge shaped piece of wood which. is curved to conform to the rolls, and which is adjust- .-able to permit of wear being taken up.
It is essential to keep the guide in close contact with the roll where the rubber first comes in contact with it, as in the absence of. this condition part of the rubber Wlll jyork under the guide. If adjustment is made on-this-form of guide the point of the wedge is driven betweenthe rolls, and
- iplinteringor breaking of the whole guide .nsually results.
In my improved guide I provide the aisual adjustable wedge shaped end piece, stud also "a separately adjustable. deflector which serves tostrip the rubber from the galender roll-and turn it toward the middle Specification of Letters Patent.
a bank of rubber 14: into in position.

of the roll. Preferably this deflector is of metal, to provide better wearing qualities,
and is located as a continuation of the end piece.
The 'end piece 16 and deflector 17 are mounted upon a bracket 18 attached to the end frame 13, it'being understood that there are two similar but inverse guides atthe opposite ends of the machine. The end piece 16 is usually' of wood, and has a curved and tapered end 19 which projects into the space between the calender rolls. For purposes of adjustment the end piece has square-headed bolts 20 sunk into its surface and passing through slots. 21 in the bracket, Nuts (not shown} on'the end of the bolts serve to hold the end piece firmly against the bracket.- When these nuts are released the end piece may be pressed toward the calender roll by screws 22, preferably square-headed, as at 23, and passing through lugs 24 in the bracket.
"Lock nuts 25 serve to maintain the screws in adjusted position. In order to prevent the screws from denting or splitting the end piece facing plates 26 may be attached to the latter. I
The deflector 17 has its inner surface 27 curved to correspond to the shape of the calender roll, and is beveled as at 28 to present a plow-"like action to the rubber forced against 'it'by the rolls rotation. In the face of the deflector adjacent the bracket is cut a T-sha'pedslot 29,'into which partially project a rib 30 on the bracket. A square headed bolt 31 extends into the slot, and is provided with a nut 32 by means of which the deflector may be clamped firmly A screw 33, provided similarly to screws 22 with a square head 34:
and a lock nut 35, passes through lug 24 16. It will also be seen that the deflector,
which is practically an extension of the end piece, can be adjusted separately from the end piece, so that closecontact between the leading edge of the. guide and the calender roll may always be kept without danger of breaking the end 19 of the end piece.
I claim 3 1. A guide for calender rolls comprising an end piece shaped to fit between a pair of adjacent calender rolls, a Separate extension of said end piece, and means for adjusting said extension independently of independently of the end piece.
I 3. A guide for calenderrolls comprising .an end piece shaped to fit between a pair of adjacent calender rolls, a. deflector adjacent the endyp iece and presenting a plow like surface to strip adhering rubber from 4 one of the calender rolls, and to direct it toward the middle of the roll, and meansfor adjusting the. deflector independent of.
the end piece. 4. A guide tween a pair of adjacent calender rolls and slidabl e on the bracket, adjusting means secured to the bracket to shift the end piece toward the calender rolls, a deflector shaped to conform to the calender roll and to strip adhering rubber therefrom, said deflector being also slidable on said bracket, and independent, means secured to the bracket for adjusting the deflector toward the calender rolls.
