Description

' A. J. RYNO V SWITCHBOARD SAFETY DEVI CE 'Filed April 7, 1926 Patented July 20, 1926.
UNITED STATES PATENT OFFICE.
ALLEN J. RYNO, or SALEM, MASSACHUSETTS.
SWITGHBOARD SAFETY IDEVIGE Application filed April 7, 1926. Serial No. 100,441.
My invention relates to safety devices for use on switch boards at central power stations and other electrical control places where safety-first precautions are paramount.
It has for its purpose to minimize switch control errors; to provide a safety device of such simplicity and easy use as to render its continued use attractive to operators; to provi'de a convenient and fool proof means for sight transmission of a give situation 011 designated circuits, as for instance when workmen are employed thereon, or other hazard exists requiring the elimination of current; to insure an uninterrupted flow of current over a given circuit; to provide an improved construction for a signaling de vice, insuring positive results and obviating the accidental operation of or damaging results to switch board equipment when placing for use or removing the same; and to provide the various other advantages and results apparent from the following specification.
I accomplish the objectsof my invention. as shown in the accompanying drawings, which form a part of this specification and, in which Figure 1 shows a view of my device on its side designed for contact with switch board equipment. Figure 2 shows a perspective view of my device showing the side exposed to vision when in switch board use and carrying thereon any given visual notice of which the out of service is but one. Figure 3 shows a section of a switch board with my safety device thereon.
Referring again to Figures 1 and 2. A shows the protecting portion of my device on the outer or exposed side of which appears the visual notice of existing conditions. B, G, D, show the extension portions on'which A is mounted and sufficiently distanced from the side E to insure a space therebetween in which the operating switch control may enter. The U shaped opening in the side E is designed to slip over the switch control on which the device .is used and to hang thereon in position until conditions on the circuit are changed and require removal.
The device is satisfactorily moulded in one piece rubber, but the portions A, B, C, and D may be made from wood or other nonconductive sheet material. The side E is preferably of rubber or other pliable and non-conductive sheet material, the pliability of which allows the removal of the device, even in a careless and inexperienced manner, without injury to or accidental opera- @0121 of the switch control over which it is use I do not desire to confine myself to the specific details of construction herein set forth, but claim all such variations and equivalents as may well be construed to fall within the scope of the appended claims.
Having thus described my invention I claim as new and desire to secure by Letters Patent of the United States of America 1. A device of the kind described, comprising a body portion shaped to fit over a switch control, having a pliable side carrying therein an opening adaptable to engage and hang on said switch control.
2. A device of the kind described comprising a body portion shaped to fit over a switch control, having a pliable side carrying therein an opening adaptable to engage and hang on said switch control, said device having on its exposed side visual means of transmitting the requirements of the circuit on the switch control of which the device is designed for use.
In testimony whereof I alfix my signature.
ALLEN J. RYNO.
