HANDLE AND SWITCH Feb v Patented Nov. 12, 1929 EDWARD W. WIEHLE; \OF CHICAGO, ILLINOIS, ASSIGNOR TO BIB/THAN ELECTRIC COM- PANY, A GORPOBATIQN OF ILLINOIS HANDLE AN D SWITCH Application filed February 1, 1928 Serial No. 251,174.

This invention relates to improvements in handle and switch, and more especially to such a handle and switch for electrically operated appliances.

In connection with many electrically operated appliances, for example, portable vacuum cleaners of the type now in common use, it is necessary or desirable to use a tubular metal handle. Such a handle is neat in appearance, strong and durable, and furnishes a housing or conduit for the electric wires leading from the. switch to the motor of the appliance.

For the purpose of illustrating my inven-' tion, I have shown my improved handle and switch as applied to a vacuum cleaner.

. are in place.

in rear elevation of a part of the handleshowing the switch, Fig. 3 is a vertical sectional view, Fig. 4 is a view taken as indicated by the line 4 of Fig. 3, Fig. 5 is a view similar to Fig. 3 showing the switch being disassembled from the handle, Fig. 6 is a view in rear elevation of the upper end of the handle showing the switch and associated parts removed therefrom, Fig. 7 is a view similar to Fig. 6 showing a modified form, and Fig. 8 is a view of the switch showing the operating lever threaded thereinto.

As\shown in the drawings, 10 indicates an electrically operated vacuum cleaner of a well-known type. 11 indicates a metallic tubular handle therefor.

Hereafter, in describing the invention I shall assume that the handle 11 is in a substantially vertical position as shown in Fig. 1. As shown in Fig. 6 the rear side of the handle 11 is provided with a slot narrow at the top as indicated by 12, said slot being widened at the bottom as indicated by 12*. The lower end of the portion 12 is provided with a small notch 12*. 13 indicates a screw hole just above the upper end of the narrow slot 12. The lower end of the slot 12 is also slightly widened as indicated by 12 to accommodate a screw.

14 indicates an electric switch mounted in a rectangular shaped block or housing. This switch may be of any well-known construction, preferably of the tumbler type. The details of the switch itself as indicated by 14 forms no part of the invention and need not,

be described here. 14 indicates the customary trigger or tumbler lever on a-switch of this kind. Hereafter I may refer to the switch itself as the switch block 14.

15 indicates the wires coming from the source of power, one of said wires as indicated by 15 leading to the switch in the usual manner. 16 indicates the wires leading to the motor of the vacuum cleaner whichv are housed in the tube 11. One of these wires as indicated by 16 comes from the switch 14 in the usual manner. Y

The widened portion of the slot in the rear of the handle as indicated by 12 is wide enough so that the switch block 14 withthe 1 wires connected thereto may be movedin or out through said opening as shown in Fig. 5. This permits very quick and easy assembly and dis'assembly.

17 indicates a substantially rectangular cover plate curved to conform to curvature of the handle and of sufficient size to cover the wide portion 12 of the opening. The lower end of this plate is provided with an inwardly extending lug 17 having projecting ears 17 The lug'17 is adapted to fit in the notch 12 and the'ears 17 look. under the sides of this notch to hold the lower end of the plate against the handle when'the parts are assembled.

- The switch block 14 is provided with two

screw holes

14 and 14. The upper end of the plate 17 is provided with a screw hole 17.

When the parts are assembled as shown in Fig. 3, the plate 17 has the lug17 hooked in the notch 12 and its upper end is secured by means of a screw 18 passing through the hole 17 in the plate and thence screwed into the hole 14 in the switch block 14. This screw passes through the widened portion 12 near the bottom end of the narrow slot 12. The

upper end of-the switch block'14 is secured by a screw 19 passing through the screw hole 13 in the handle and inserted in the screw hole 14 in the switch block 14. When assembled,

' the switch block 14 lies substantially under the narrow slot 12 and the operating lever or trigger 14 is adapted to move in the slot 12.

The plate 17 is provided with a substan- V tiallycentrally arranged hole 17 for the wires 15 and there is preferably mounted over this hole a curved hood or guard plate 20 with a flexible spring wire guard 2l-to protect the wires 15.

In assembling the parts, the connections may be made to the switch block 14 while it is outside the handle. It is then inserted through the opening 12 as shown in Fig. 5 and slipped upwardly until it lies under the narrow slot 12 with the trigger 14 projecting therethrough. The cover plate 17 is then placed over the opening 12 and the lug 17 with the projections 17 hooked into the notch 12 The

screws

18 and 19 are then put into place thus holding all the parts securely.

In the form shown in Fig. 7, instead of hav ing a single opening with wide and narrow portions, I provide two separate openings, namely, the relatively wide opening 112 and the relatively narrow opening 112 adjacent thereto. In using a device of this character, the switch preferably has the operating handle 14 threaded into the part 14 as shown in Fig. 8, the end of the lever 14 being provided with a threaded end 14 In assembling a switch of this kind, the handle 14 is removed, the'switch inserted through the opening 112*, and then moved to a position beneath the opening 112. The handle 14 is then inserted through this opening and threaded into the switch. Obviously, if the diameter of the tube 11 is large enough, or the switch handle short enough, the handle does not need to be removed from theswitch in be inserted through the large opening and the handle pushed up through the small opening.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention disclosed in the appended claims, in which it is my intention to claimall novelty in my invention as broadly as possible in view of the prior art.
