SHUTTER WORKER AND FASTENER.

SPECIFICATION formingpart of Letters Patent No. 642,655, dated February 6, 1900.

Application filed June 19, 1899. Serial No. 721,110. (No model.)

To all whom it may concern:

Be it known that I, ALVIN WELLING, a citizen of the United States of America, and a resident of Oovington, in the countyof Kenton and State of Kentucky, have invented certain new and useful Improvements in Window- Shutter Workers and Fasteners, of which the following is a specification.

This invention relates to certain improvements in shutter-workers such as are employed for openingand closing window-shutters without requiring the raising of the sash; and the object of the invention is to provide a device of this character of a simple and inexpensive nature which shall be capable of being readily applied in position for use and shall be capable of ready operation to open or close the shutter.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved shutter-worker whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted for use, all as will be hereinafter fully set forth.

The novel features of the construction will be carefully defined in the claim.

In the accompanying drawings, which serve to illustrate my invention, Figure 1 is a fragmentary sectional view taken through the lower part of a window-casing and showing the improved shutter-worker in position for use. Fig. 2 is a sectional view taken transversely through the shutter and side of the window-casing in the plane indicated by the line a a in Fig. 1. Fig. 3 is an enlarged plan View of the lower hinge member forming a part of my improved shutter-worker. Fig. 4 is a sectional View taken transversely through the operating-shaft of the device in the plane indicated by the line b b in Fig. 1 and showing the means for holding said shaft against movement. Fig. 5 is a vertical sectional view taken axially through the hinge in the plane indicated by the line 0 0 in Fig. 2.

In the views, 1 indicates the side of the window-casing, and 2 indicates the sill thereof.

3 represents the shutter, hinged at its lower part to the casing side 1 by means of a hinge formed of two members 4 and 5, the member 4 being secured to the casing side 1 and having a projecting strap 6, provided with an upwardly-extending pintle 7 at its extremity, and the member 5 being secured to the shutter and being formed with a projecting strap 9, the extremity of which is provided with a socket or eye 8 to receive and turn upon the pintle 7 in opening and closing the shutter.

The socket or eye portion 8 of the hinge member 5 is formed, as clearly shown in the drawings, with a segmental bevel toothed gear-surface 10, with which meshes a bevelpinion 11, held on a shaft 12, which extends through the casing side 1, as shown in Fig. 2, the outer end of said shaft being journaled in a boss 13, formed on a flange 14:, extending at right angles from the main part of the hinge member 4 and adapted to fit flush against the outer surface of thecasing side 1, as clearly shown in Fig. 2. The boss 13 projects out from the face of the flange 14 and serves to hold the pinion 11 in mesh with the gear-surface 10.

The shaft 12 extends through the casing side 1 into the interior of the house and has its inner end journaled in a boss 15, formed on an escutcheon-plate 16, secured on the innor face of the casing side. The boss 15 is made thicker at its top side, as clearly shown in Fig. 4, to receive a screw 17, the tip of which bears on the shaft and is capable of being set thereon to hold the shaft against rotative movement when the shutter has been opened or closed. The inner extremity of the shaft 12 is formed with a square 18 to fit a squared opening in a crank-handle 19, which may be of any form or length and by'means of which the shaft may be conveniently turned in operating the shutter.

The strap 6 of the hinge member at is formed, as clearly shown in the drawings, with an enlargement or head 20 at the base of the pintle 7, and in the upper surface of said head and also in the under surface of the eye or socket 8 of the member 5 are formed corresponding ball-races 21, as clearly shown in Fig. 3, adapt ed to receive balls 22, interposed between the two parts or members of the hinge, so as to materially reduce the friction caused by swing-' ing the shutter into opened or closed position, as will be readily understood.

In use when it is desired to open or close the shutter the crank-handle 19 is applied to the squared end 18 of the operating-shaft 12 and said shaft is turned so as to move the shutter pivotally upon the hinge-pintle 17 by reason of the intermeshing of the bevel'gears 10 and 11. hen the shutter has been opened or closed, as the case may be, the set-screw 17 is turned so as to securely clamp the shaft 12 and hold the same, as well as the shutter operated therefrom, against turning movement.

The ball-bearin g interposed between the two hinge members materially lessens the effort required to open or close the shutter and does not add greatly to the cost of the device. The stops ordinarily provided upon shutterhinges are not required in this construction, since the set screw 17 aifords a simple and durable means for holding the shutter against slamming when opened and against being opened from outside the house when in closed position.

The improved shutter-Worker constructed according to my invention is especially Well adapted for use by reason of its simplicity and cheapness and also on account of the fact that it interferes in no Way with the lifting of the shutter off its hinges, and it will also be obvious from the above description of my invention that the device is capable of consid' erable modification without material departure from the spirit and principles of the invention, and for this reason I do not Wish to be understood as limiting myself to theprecise form and arrangement of the several parts herein set forth.

ward from the center of said head and adapted 1 for engagement with the eye or socket of the shutter member, said head and socket being formed in adjacent surfaces with correspondin g an n ularball-races, balls heldin said races, a shaft, extended through the window-casing and also through the perforation in said flange and provided with a bevel-gear at its outer end adapted for engagement with the gearsurface of the socket portion, an escutcheonplate secured to the inner surface of the window-casing and formed with a boss through which said shaft is passed, and a set-screw held by said boss with its tip arranged to engage the shaft to hold the same against turnin g movement, substantially as set forth.
