ENTERING-GUIDE FOR CALENDERING-ROLLS.

$PECIFICATION forming part of Letters Patent No. 333,283, dated December 29, 1885.

Application filed July 34,1895. Serial No.172,585. (No model.)

To all whom it may concern: of a sliding movement along the rods; 2.1 Be it known that I, lllADISON II. CRAM, of also upon a rod, 70, which extends from one Pawtucket, in the county of Providence and the bearingstandards to the other at the sar State of Rhode Island, have invented a new height and parallel with the guide-r0610,

and useful Improvement in Entering-Guides placed the loose pulley Z. The weight E for Calender-Rolls, of which the following is provided with the upright ears m m, betwe a specification. which is pivoted the loose pulley 0, and t Heretofore it has been acomparatively difopposite weight, E, is in like manner p1 ficult and dangerous operation to thread the vided with the loose pulley n. The narrt 1o calender-rolls of a paper-machine or of a endless guide-belt F, when inits normal po cloth-calendering machine; and the object of tion, as shown in Fig. 3, passes from the o: my invention is to provide a simple and effiriage-pulleyf over the smaller end portion cient means for guiding the paper or cloth the top roll B, thence downward from side between the rolls wit-h certainty and precision; side between the smaller end portions of t and it consists in the combination,with the set rolls and under the bottom roll B, ther. of calender-rolls, of two narrow endless belts over the loose pulley j upon the rod h, th passing together between the rolls, and means under the loose pulley 0 of the weight E, a for shifting the location of the belt along the upward to the pulley f. The narrow endl rolls, as hereinafter fully set forth. belt G, which runs over the rolls B in cont:
