Applicaties september 19, 1944, serai No. 554,802 i claims. (ci. zoo-i12) It is an object of this invention to provide a multiple part protecting waterproof shield for a toggle switch and similar electrical equipment whereby the securing means for the shield may be located wholly Within the shield.
It is an object of this invention to provide a waterproof protecting shield of flexible material, such as rubber, rubber composition or any other suitable material.
It is also an object of this invention to provide an unique structural means wh'ereby the flexible waterproof shield may be secured to the switch in a waterproof fashion defining a waterproof connection between said switch, switch casing and said shield.
It is an object of this invention to provide a flexible shield having a tubular handle portion closely embracing a tubular bearing sleeve which is adapted to slidably engage the toggle handle of the switch,
Other features of novelty will appear in th'e specic description of the invention as disclosed in the drawing which represents the preferred embodiment of the invention.
In the drawings:
Fig. 1 is a sideelevation of a toggle switch having our waterproof protecting shield secured thereto.
Fig. 2 is a central vertical section through our protecting shield as applied to a conventional toggle switch.
In the drawings the panel portion i of the yswitch casing is a support for the toggle switch 2 having a screw threaded hollow stem 3. The stem 3 passes through the washer t, panel portion i, the iexible washer 5 the rigid tubular flanged connecting element 6 and is secured and supported in a waterproof condition by the nuts 'i and 8.
The exible waterproof shield 9 comprises a skirt i and a tubular handle portion il connected by a ilexible diaphragm i2. T'he tubular connecting element 6 is provided with an out turned ilange or bead i3 on one end and an inturned flange M on its other end. The tubular handle portion il is provided withva bearing sleeve i received therein. The bearing sleeve l5 loosely and slidably engages the toggle operating means or handle I6.
The skirt i0 is preferably provided with a shallow annular groove to receive the clamping ring i1.
The shield 9 and the flexible washer 5 are preferably made of plastic material such as rubber, rubber composition, or any other suitable plastic flexible material that may accomplish the desired function of the shield 9.
The bearing sleeve l5 may be made of brass titi or any other comparatively rigid material that will slide easily along the operating handle it of the switch t.
It is to be observed that the shield t when secured in position with the washer 5 forms a complete imperforate waterproof cover for the outside portion of the toggle switch 2.
The imperforate shield or cover is, at least, analogous to and the equivalent of insulating means since it maintains an insulated path for the ow of electricity and the operator is insulated electrically from the switch by the rubber shield or cover.
The skirt l@ of the shield d is ilrxnly secured to the rigid tubular flanged connecting element t by the helical spring band or clamping ring il.
The application and attachment of our waterprooi shield t to a conventional toggle switch t on a panel portion i is very simple. when the toggle switch is in secured position on a panel portion i by the nuts l and d, it is merely necessary to remove the nut apply the yieldabie waterproof washer t also tubular flanged connecting element t and re-apply the nut t to the threaded stem t as shown in Fig. 2. Next the skirt I@ is applied over the flanged free end of the element d in the meantime the operating means I of the toggle switch is guided into the bearing sleeve It and, lastly, the spring clamping ring il is applied to the skirt l@ to securely maintain the shield t on the switch 2.
It is to be noted that our shield construction is essentially an attachment to a known type of toggle switch that is in general use. Our attachment comprises a. plurality of attachable and detachable elements, parts or units. One unit includes a tubular handle integrally connected to a tubular skirt portion by a flexible diaphragm. The bearing sleeve it within the handle ccmprises ancther unit. The tubular flanged ccnnecting element t comprises another unit. The washer and the clamping band Il are two other units which make a total of five distinct units.
All of these units, when assembled in operative relation, constitute an attachment to seal a switch against the entrance oi' water or any other fluids that may be present in the atmosphere ambient about the switch.
Inasmuch as the securing means for the attachment is located solely within the shield it is essential that the shield be made of a plurality oi separate individual units which can be readily assembled and secured together in operative relation.
In making the assembly no additional screws. nuts or bolts are needed. since it is merely necessary to use the screw threaded stem of the switch and its screw threaded nuts to secure the water proofing attachment in place on the switch.
This protecting shield has a field of application under conditions where it is necessary to protect toggle switches and like electrical equipment from the entrance of water. or other liquids into the equipment -and thereby protecting such equipment for elcient operation.
The shield is especially useful in boats, vessels, planes, landing craft, etc.
It will now be clearly understood that we have produced a novel and unique attachment for electrical equipment, such as electric switches which have, at least, one screw threaded nut for holding the electrical equipment or electrical switch in place when installed Our invention not only constitutes a novel attachment, but when installed, on electrical equipment, such as a switch, constitutes a new combination oi switch and waterproofing attachment therefor.
