8 Claims.
My invention relates to improvements in case'- ment adjusters.
Such devices usually comprise a housing secured to the window sill, with an arm pivoted thereto to swing outwardly in a horizontal plane and open the window, the outer end of said arm sliding through an apertured fixture on the sash. In most instances the arm is swung outwardly and inwardly by means of a worm and gear actuated by a crank. The worm is mounted in suitable bearings and both the worm and the gear are carefully made and assembled so that they may rotate without binding.
The object of the present invention is to provide a easement adjuster of the worm and gear type in which the parts are so designed and so assembled in the housing, as to provide a very inexpensive construction but one which, nevertheless, shall render satisfactory service.
As contributory to this end, other objects are: to provide a device of this character in which the worm fits in and rotates in a cylindrical holder, thus eliminating end bearings or journals; to provide a device in which the housing consists essentially of two parts held together by a single rivet; to provide a construction in which the base plate of the housing is apertured to receive the cylindrical part of the cap and hold the latter against side play, thus making possible the use of the single rivet referred to; to provide a construction having these variousadvantages but nevertheless being reversible, i. e. adapted for right hand or left hand mounting and operation, and to provide a construction wherein rattling is eliminated.
In the accompanying drawing I have illustrated a .commercial embodiment of the invention, in which:
Fig. 1 is a top plan view of the devicel applied to a easement window;
Fig. y2 is an elevation thereof; Fig. 3 is an enlarged sectional 3-3 of Fig. 1; y
Fig. 4 is a top View of the base of the housing with the upper part removed;
Fig. 5 is a section on the line 5-5 of Fig. 3;
Fig. 6 is a plan view of the device with the upper part removed; and
Fig. 7 is an elevation of one of the parts.
Figs. 1 and 2 show part of a easement window with the device applied thereto, IU being the Window sill and II being part oi the window frame shown in section. The easement window I2 is hinged at I3. The easement adjuster is assembled with a housing, which, for practical purview on the line tinghover the margins 2| so that these bent-over parts overlie the uplarger scale in Fig. 5.
poses, may be considered as a two-part structure held together by a single fastening device, such as a rivet. The lower part or base plate I4 is stamped from sheet metal with a depending flange VI5 and with openings therein to accommodate screws II which fasten it to the window sill in the position shown in Fig. l. Said base, in the form shown in Fig. 4, has an opening I'I therein with ears or abutments I8 struck up therefrom. An opening I9 is also punched in the base to receive the fastening means. l The upper part of the structure consists essentially of a rectangular strip of metal bent around to substantially U shape, the bend providing an offset cylindrical housing 2l) with parallel arms 2l and 22 projecting therefrom. The arm 2| constitutes the top or cover of the housing. The lower arm 22 rests on the base plate with the cylindrical portion 2l! received within the opening I'I and confined by the walls thereofv and also confined between the parallel upright abutments I8. Said cylindrical portion is offset downwardly, as shown in Fig. 3. 4
The easement is swung outwardly and inwardly by a worm and gear in the usual manner, the worm 23 in this instance fitting within the cylindrical housing 23 and conned thereby and by the end uprights I8, I8, as shown more particu- `larly in Figs. 3 and 5.
The worm meshes with the gear 24, of the' usual configuration, the said gear being confined between the horizontal plate 22 `and the washer 25, the parts being held together by a suitable rivet 26, surrounded by a brass or other noncorrosive sleeve, shown in Fig. 3. In View of the fact that the cylindrical part of the uppergmember rits into the opening in the lower member and is thus conned against movement longitudinally or transversely and is additionally confined between the upright abutments I8, a singlel rivet suiices to complete the assembly of the entire housing and the parts contained therein.
The parts are further locked together by bend- 21 of the upper metal arm shown in Fig. 2 and on a In this way a very simple but strong mounting is provided for the worm 23 without employing the usual journals at the ends, thus avoiding the necessity of machining the parts, and otherwise reducing the cost of manufacture and providing a device in which the worm and gear are held in definite xed relation, insuring smooth operation.
The worm 23 has a square opening 28 through right abutments I8 as the same to receive the square end of the small crank 29, which may be iitted into either end of said worm. Thus the housing may be mounted either at the right or left hand side of the window frame and be operated by the crank in either position. In other words, the device is reversible.
The gear 25 has a flat metal arm 30 projecting therefrom, in the usual manner, being secured thereto at 3|, preferably by butt welding. This arm, which is a strip of flat steel, has a certain resiliency which enables it to accommodate itself to slight irregularities in the movement of the casement window. Said arm passes through a guide or bracket 32 secured to the casement window. This guide is formed from a strip of metal bent over at the middle, as shown, with the two ends bent outwardly and perforated to receive screws 33. A strip of ber 34 is clamped between the arms of the U shaped iitting thus formed and has an opening 35 through it. The metal tting itself is also stamped with somewhat larger openings 36, the purpose of the arrangement being to permit the flat arm 30 to slide through an opening in a sheet of sound deadening material. In other words, there is no contact between the metal arm 30 and the metal bracket 32, and the noise, due to rattling, which may occur after long continued use, is largely eliminated.
The device described herein is of such construction as to be made largely by stamping operations, and requires very little machining. The worm, instead of being supported by trunnions or bearings at its ends, is supported by the cylindrical housing which surrounds it. The rivet constitutes the shaft about which the gear turns and the arms of the U shaped member in which the rivet is mounted are each reinforced. The upper arm is reinforced by the washer 25 and the lower arm by the base plate I4, thus providing a double thickness of metal on each side of said gear.
The terms upper, lower, horizontal, etc., are used herein in a descriptive sense and not in a limiting sense, as will be apparent. Various changes may be made in the preferred form of the invention described in detail herein without departing from the scope of said invention.

1.
