PAPER-MAKING MACHINE.

To all wiwm it may concern:

Be ,it known that I, WILLIAM SHEAIIAN, a citizen of the United States, and a resident of the city of Ocean Falls, Province 5 of- British Columbia, Dominion of Canada,

have invented a certain new and useful Improvement in Paper-Making Machines, of which the following is a specification.

This invention relates to the process of manuiacturing paper by machines. As well known, such machines comprise press-rolls, by which the water is pressed out of theweb of paper, and drier rolls or driers; and the web has to be carried to said press-rolls and from these to the driers.

Heretofore, it required a skilled attendant at each of the rose rolls whose duty it was to guide the ead' end of thewebof paper by hand, to said rolls. Such work involved some danger to theattendant, also involved loss of time, and waste of paper;

The web of paper being moist, the leading. end has a tendency to cling to one of the rolls between which it passes, if there are no guiding means.

The object of my invention is to rovide mechanical means by which the said lead end of the web is ided to and thru the press rolls to the drlers.

I attain my object by means of compan on ropes or carriers travelling in contact w1th each other, and extending to and between the rolls, over and between which the lead end of the web of paper is to be guided.

5 At the receiving end of the first set of press rolls, these carriers are spaced apart so as to facilitate the insertion between of said lead end of the web, and a little farther on the carriers are brought into contact jwith each other, so as to grasp and hold the lead end, and in that wayfcarry and. guide the same thru the press rolls to the driers.

Other uses and v-applications of my invention will suggest-"themselves. I 7

ing drawings, I have diagrammatically ilustrated the practical application of; my invention, the figures,

, showing as follows:

. I 2 re resent-endsections of a Figs: 1 and paper making mac ine, the views showing two sets. of press-roll, and one of the drier, v i end a s rolls; and

\ end of the web being "usually" torn .na1l across.

Fig. 3 is a fragmenta dia mmatic view of those ends of the gress r dlls adjacent the ropes or carriers, the upper roll being shown in section and the lower in side elevation; and this view shows the means provided on the projecting end of the upper roll for guiding the carriers past these press rolls, and so as to cause the, carriers to travel at the same rate asgthe web of paper.

In describing1 the devices shown in the drawings, I wi refer only to those parts which deal directly with my invention. The views shown represent parts of a machine of standard construction, therefore well known to all conversant with the paper making art.

a and I) represent one set of press rolls, and 0, 0! represent another set of press, rolls, it being understood that the machine may have any number .of sets of press rolls. The line e represents the felt running thru the machine. f and g are the two endless ropes or carriers by which the lead end of the web of paper,. designated by the broken line g in Fig. 1, is conducted to and between the press rolls, and finally to the means, such as ropes h, for example, by which the web of aper is conducted to the drier rolls.

t the receiving end of the machine shown in Fi 1 the carriers f and 9 run over sheaves i an i, which are arranged to guide the carriers side by side along one edge of the web of paper, but these sheaves are vertically spaced apart so as to separate the receiving ends of the carriers and permitthe placing of the web of pafiper between them, as dia ammatically i ustrated by broken ine fiin Fig. 1. A'short dlstance be 0nd the s eaves 2' and j is provided anot er sheave 1-, for supporting the carriers f and g the latter converging to that point, in so doing gripping and holding the lead end of the web of paper, and ulling and guiding the -same thru the rst set of press rollsa and b.

In order toguide the web'of paper towards the press rolls it is only necessary to seize and hold one ed'ge' 'thereof this diago- T 6 upper 1press roll a is'provided atone eave eIement consisting of a the w flanged guide ring 3 seated on ball bearings z mounted'on said end a's shown in Fig. 3. Thetlanged ring 3 serves as a guidefor the carriers f and g as illustrated in Fig. 3, since the strain on said carriers tends to hold them against the upper roll a.

The carriers f and 9 pass from the first set of press rolls to the secondset 0, and 0!, as illustrated in 2, running over sheaves s, t, u, to said second set of press rolls, the upper c of which is also provided with guiding means for the carriers like those shown in Fig. 3. The means provided on the upper of the press 'rollsforguiding the-carriers mustbe adapted to cause the latter to travel at the same speed as that at which the web of paper is traveling. I

From the second press rolls 0, d, the carriers pass over sheave w to the drier roll m,

at which point the carriers are carried over a pair of sheaves 3, which are arranged to separate the carriers laterally so as to release the lead end of the web of paper. The lead end of the web of paper having arrived at the drier roll w is then seized by the other guide ropes or carriers h by which the lead end is carried over the drier roll as and the drier roll 00'.

It" shows another of the carrierscarrying the leadend of the web of paper over the drier rolls. The latter carriers are arranged substantially as shown in my Letters Patent of the United States reissued June 8, 1915,

No, 13,925, entitled Improvement in drier rolls for paper making machines.

'From the sheave 3 the carriers f and 'g' peass over the sheave p, which is assumed to driven by being connected thru the medium of a clutch with a suitable driving "mechanism all of which details are readily understood and therefore are not described. A The carriers run overthe sheave p to the "sheave 0, thence over ti htening devices such as shown by m, a tin ig. 1; and from the sheave Z' of the latter devices the carriers run over sheave 70 back to the sheavesi and y. When the lead "end of the web of paper has iteachedthe drier fioll m the driving of the sheave 'pjswhich drives the carriersmay be discontinued by throwing out the clutch of the sheave p until the carriers f and g are again required-to be thrown into action.
