UNITED STATES rATENT OFFICE.
WILLIAM WESCOTT, 0F WATERTOWN, NEW YORK.
- ALARM FOR PAPER-MAKING MACHINES.
Specification of Letters Patent.
Patented July 4, 1916.
Application filed September 28, 1914. Serial No. 863,169.
Be it known that I, WILLIAM WESCOTT, a citizen of the United States, residing at Watertown, in the county of J efierson and State of New York, have invented new and useful Improvements in Alarms for Paper- Making Machines, of which the following is a specification.
The invention relates to an improved alarm for'paper making machines designed with a view to automatically indicating a break in the paper in order to prevent damage and loss of material incident to the failure to be advised of'the break at once.
. The main object of the present invention is the provision of automatically controlledaudible alarms arranged adjacent the first drier and beyond the last drier, the unbroken condition of the paper .web maintaining these alarms inactive, the weight of the web when broken serving to permit actuation of the alarms to indicate such condition.
The invention in the preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in elevation illustrating the improved alarm. Fig. 2 is a plan view.-
In 'carrylng out the present invention, I.
provide between the final press roll 1 and the guideroll 2 leading to the first drier roll 3 an alarm mechanism designated generally by 4. I
The alarm tively' driven roller 5 mounted in supports 6 rising from the drier frame7. A contact block 8 is mounted in the roller and push contact members 9 are slidably mounted in the roller for rotary movement therewith, being normally held projected beyond the surface of the roller and free of engagement with the contact 8. The contact 8 and both contacts 9 form respective terminals of the alarm circuit including conductors 10 and 11 which lead to any suitable point and include an audible alarm such'as a'bell 12 anda source of energy such as a battery 13.
In connection with the electric alarm I mechanism includes a posi J also mount a fluid pressure alarm adjacent the-roller 5., The fluid pressure alarm comprises supports 14 rising from .the drier frame/7, in which is supported a shaft 15 having a crank 16 at one'end thereof, which crank is connected to the valve lever 17 which controls a valve 18 in the steam pipe 19 leading from'the drier roll, the terminal of the pipe being provided with a whistle 0 other s1milar alarm' 20. Secured upon the shaft 15 is an inverted U-shaped frame 21, the cross bar of which forms the operative support for the paper.
The described alarms are arranged between the press and the first drier, it being understood that when the paper is passing properly from the final press roll to the -gu1de roll 2, it is supported above and wholly free from engagement with either of the contacts 9 or the cross bar 21.
In the use of the alarm mechanism, it will be obvious that should the paper break in passing from the final press roll to the first drler, the weight of the paper falling on the roll 5 and on the cross bar 21 will actuate both alarms at this end of the machine. If the break occurs on the final or delivery end of the drier, pressure of the paper on the roll 22 is relieved, whereupon the roll is elevated by the spring bearings and the valve 25 opened tosound the alarm 26.
What is claimed is An alarm for paper making machines arranged intermediate the. final press roller and the initial drier roller, said alarm in-
