The presentiapplifiiitihn is d'ifieted nitir espelng =-undrstood th illustrated in Fig. 7 and in the left hand part of Fig. 1 of the parent application Ser. No. 405,638, already referred to. One of the plate cylinders of the printing press is indicated by 1, having its shaft 2 journaled in the press frame. The inking mechanism of the plate cylinder is indicated diagrammatically at 3. The impression cylinder 4 cooperates with the plate cylinder 1 to make the first impression, the web a; runningbetween the cylinders.

Referring now more particularly to the mechanism for handling the roll of printing paper which is to be supplied to the press, a pair of bearings 10 of the press frame. The trackways 11 are approximately horizontal, but preferably are very slightly inclined inwardly or toward the printing mechanism proper soas to facilitate the rolling or sliding of the new roll of printing paper into position in the bearingslO. A second pair of bearings 12 for themandrel of the roll at of printing paper are preferablyprovided, similarly to the two pairs of bearings 29 and 31 shown in Fig. 1 of the parent case for the offset.

roll.

In the illustrated embodiment, a pair of guideways 13 .and 14 are provided on the ends of the press frame, and these are preferably vertically or approximately vertically arranged. These guideways are preferably T shaped, as best shownin Fig. 6. Mounted to slide or travel along the guideways, respectively, are

saddles

15 and 16, which engage-beneath the ends of the mandrel. 17. The saddles are formed with a guide member 20, which is provided with a face21 engaging with the face of the guideway 13, and'is alsoprovided with

side portions

22 and 23 extending along the sides of the guide 13, and with

inner end portions

24 and 25 which extend back of the guide 13. Thus the saddles embrace their respective guides, but are sli'dable therealong.

Each of the saddles is provided with a roll-supporting member, consisting of apart 26 extending outwardly from the body 20 of the saddle, the upper surface of the memher 26 engaging beneath the corresponding end of the mandrel 17. of the member 26 is preferably inclined inwardly and downwardly toward the. cor- .respondingguideway 13 or 14-, so that as the roll is lifted the action of gravity will cause the mandrel 17 to rest both on the saddles against the faces of the

guides

13 and 14, and thus be secure from rolling off the supports. This construction enables the mandrel 17 to pass over the saddles 20 when they are depressed but very little below the mandrel, and obviates the necessity of any special fastenings or other. mechanism for are formed, respectively, in a pair of trackwaysll, which are formed on the upper side or edge of a part a load.

lhis upper surface holding the mandrel in against its slipping off the saddles after the roll .90 has been lifted from the floor or other support. This construction also permits and facilitates the sliding or rolling of the mandrel from the saddles onto the trackways 11 when the saddles had been raised to thelevel of the trackways.

Means are provided for raising and lowering the saddles and for holding them in any desired position along their path of travel. As embodied, two bars 30 and 31extend downwardly, respectively, from the

saddles

15 and 16, and may conveniently extend into depressions in the floor. On its inner edge the bar 30 is provided with a straight gear 32, and bar 31 is provided with a like gear 33. Meshing with the gear 32 is a gear wheel 36, and meshing with the gear 33 is a gear wheel 37, both gear wheels being fixed on a shaft 38, which shaft is journaled at 39 and 40 in the machine frame.

The embodied form of means for rotating the shaft 38 comprises a ratchet wheel 44 fixed on the shaft 38, a lever 45 loosely pivoted on the shaft, and a pawl 46, which is pivoted on lever 45 and engages with the teeth of the ratchet 44.

Suitable detent means are provided for the ratchet wheel 44, and preferably in connection therewith a release and a braking mechanism, whereby the saddles may be lowered under control either. with or without In the parent case this mechanism is shown applied to the same construction of pawl and ratchet mechanism for the offset roll, andin the same relation. As embodied, in Fig; 5, a detent 4-7 is pivoted at 48 on the machine frame, and is provided with a tail 49 which may be actuated by the foot of the workman. Extending from the tail 49 is an arm 50, provided with a brake shoe 51 adapted to engage with a brake pulley or roll 52, fixed on shaft 38. A spring 53 yieldably holds the detent to the ratchet and the brake off from the brake pulley.

The manner of operation of the mechanism will be clear in the main from the foregoing. In Fig. 2 of the drawings, the web from paper roll x is shown running into the press and a new roll of paper 00' is shown resting upon the floor, and with the saddles 26 in position therebeneath, ready to lift the roll by its mandrel 17. In Fig. 4, the now almost depleted roll 03 has been moved from the bearings 10 to the bearings 12 to make room for the new roll :12, and the roll w has been raised, through the actuation of hand lever 4-5, and the upper surface of the saddles 26 are shown just flush with the corresponding trackways 11, whereby themandrel 17 of the roll x will be rolled or slid with very little effort onto and along the trackways 11. 1
