Claims.
This invention relates to mechanical telegraphs used to transmit signals from the bridge of a ship to its engine room.
Thi application is a substitute application for application Serial No. 419,873; filed November 21, 1941, and abandoned October 4, 1944.
One object of the invention is to provide a mechanical ship's telegraph which will reduce the possibility of errors in the transmission of orders. 7
' Another object is to provide a ships telegraph which will eliminate the necessity of further action by the engineer after setting the engine as directed from thebridge.
A further object is to provide a ships telegraph which will at all times indicate the setting of the engine.
Other objects will become apparent upon considering the following specification, which, when taken in connection with the accompanying drawing, illustrate one form of the present invention.
According to the invention a two way telegraph ssytem is provided between the bridge and the engine morn-said system including an indicator in the engine room and an indicator on the bridge, with means on the bridge to actuate the indicator in the engine room, and means coordinated with and actuated by the engine control means to operate the indicator on the bridge.
In thedrawing:
This application April 19; 1945, Serial No. 589,143
Fig. 1 isa diagrammatic view in elevation of a mechanical ships telegraph embodying the invention and Fig. 2 is a cross-section taken on the line 2-2 of Fig. 1, looking in the direction of the arrows.
Referring to the drawing in which like numerals indicate like parts in both views, the bridge telegraph, generally designated it, may comprise a hollow pedestal H, on which is mounted a cylindrical head iii. The head 12 has a dial [3 on one end thereof which indicates the desired orders to the engine room. A shaft I 4 is mounted in the head and projects through the dial l3. An actuating lever t5, having an open central portion l6 and a handle ii, is keyed to the shaft M to turn it. A sprocket or pulley i8 is keyed on the shaft M for actuation by the handle IT. The sprocket or pulley l8 actuates a chain or cable l9 effecting a similar movement on the engine room telegraph, generally designated 20.
The engine room telegraph may be constructed of a cylindrical drum 2! having a dial 22 on one end thereof to indicate the order from the bridge telegraph Ill. A shaft 23 is mounted axially in the drum and has a pointer 24 keyed thereto. A
sprocket or pulley 25 iskeyed 'to theshaft-lS, the sprocket or pulley 25;: being actuated byithe cable is from thebridg -telegraph.-
A double sprocket or pulley 2123 is mounted to rotate freely on the shaft.23-. The sprocketor pulley 2i28 is actuated: by 'a belt- .or chain" 29 operating between the sprocket 'or pulleyZ-B and a sprocket or pulley 30 carried by a shait 3 and actuated by an engine controlleverw 32 which regulates the speed and direction of the engine (not shown). l The sprocket 0r pulley 2'! which forms apart of the double pulley 21-28 carries a chain-or cable 3 3, which engages a sprocket or Pulley 35 on the shaft M. The sprocket -or .pu1=ley.-;35 is mounted to rotate relativatojthe shaft. I14; and
carries a pointer 35', which'is adapted .to& show through the aperture It in the. leveril5' to indicate whenthe order from th'ebridge to the engine room has been executed.
Similarly an indicator 43 is fixed: the hub of the double pulley or sprocketZF-Zd and op;- crates around the face of the 'dial 22 and-indi cates to the-engineerathat the engine control lever 32 is imposition to execute the bridge'iofli cers command.
In operation when the bridge ofiicerwishescto transmit an order to the engine room he Lfirst moves the handle l1 across .the uppermost position; which causesa hammer 38 toistrike'a bell 39 in the. engine room:telegraph 2U' and'icall' the attention of; the engineer to a change in orders. The handle I! is then moved to the position desired. Movement of the handle ll turns the sprocket or pulley l8 which causes a correspondin movement of the sprocket or pulley 25 and the pointer 24, causing the pointer 24 to indicate the same order as the handle ll.
The engineer then proceeds to make the appropriate setting by movement of the lever 32. Movement of the lever 32 to the position indicated on the dial 22 by the pointer 24 causes ro-- tation of the double sprocket or pulley 21-28 which turns the sprocket or pulley 35 on the shaft i i. Turning the sprocket or pulley 35 causes the pointer 3t to turn to the position indicated by the speed of the engine, thus placing the pointer indicator 40 not only that the order has been received but that it has been correctly executed.
Having thus described the invention it is realized that it is susceptible to various changes and modifications. It is not, therefore, desired to limit the invention to the precise form herein shown and described but only by the scope of the appended claims. The invention is hereby claimed as follows: 1. In a ship telegraph system, a bridge telegraph including a dial having desired orders indicated thereon, a lever movable to any of said indicated orders and a pointer movable to any of the orders indicated, an engine room telegraph including a dial having ordersindicated thereon corresponding to the orders indicated on the bridge telegraph dial and a pointer movable to any of said orders, means actuated by said lever.
to actuate the pointer on th engine room telegraph, an enginecontrollever, and means actuated by the engine control lever toactuate' the pointer on the bridge telegraph.
2. In a ship telegraph system, a bridge telegraph including a dial having desired orders indicated thereon, a lever movable to any of said indicated orders and a pointer movable to any of the orders indicated, an engine room telegraph includinga dial having orders indicated thereon '-corresponding to the orders indicated on the bridge telegraph dial and a pointer movable to any of said orders, means actuated by said lever to actuate the pointer on the engine room telegraph, an engine control lever adapted to regulate the speed and direction of the engine, and
a cable actuated'b y the control lever to actuate sending member. movable to any of the orders indicated, and an operator controlled engine control .means movable to stop or change the direction of rotation of the engine and its speed, means actuated by the sending member on the bridge to actuate the receiving member on the .4 engine room telegraph, and means actuated by said engine control means to actuate the sending member of the engine room telegraph and the answer back member of the bridge telegraph.
4. In a ship telegraph system a bridge telegraph including a dial having desired orders indicated thereon, a lever movable to any selected one of said indicated orders and a pointer movable to any of the orders indicated, an engine room telegraph including a dial having orders indicated thereon corresponding to the orders vindicated on the bridge telegraph dial and a pointer movable to any selected one of said orders, means actuated by said lever to actuate the pointer on the engine room telegraph from the bridge, an engine control lever adapted to regulate the speed and direction of the engine and means actuated by the movement of the control .lever to actuate the pointer on the bridge telegraph to indicate the speed and direction of the engine.
