HOTI-AI-R REGISTER.

To all whom it may concern:

I it known that I, RICHARD S. T. OIssEL,a citizen of theUnited States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Hot-Air Registers, of which that class in which the pivoted slats are ad: usted by means of a connecting rod pivotally connected with the slats and operated by the following is a specification.

This invention relates to hot air registers of a lever fulcrumed in the supporting frame.

The invention consists, in such a register, of an organization involving a locking surface on the frame of the register, a sheet metal pieceor box that is prevented from turning by sa d surface and has a bushing in which the slngle belt that passes through the side of the framelies, an ordinary nut on the end of the bolt that is, with the sheet metal piece or box, prevented from turning, and the operatrng lever that has its bearing on said bushing between the 1 sheet metal piece and the side frame of the-register. p

The mvention further consists in an organization in which the pivoted slats are ec-- centrically connected by a governing rod operated by a lever that is pivoted to the supthe supporting frame, which boss serves to porting frame and retained by-a nut seated in a sheet metal box having'a central .bushmg for the screw pivot and a raised concen-.

trio friction flange, said box and contained nut being seated in an angularly recessed boss of prevent the axial turning of the box and screw nutand the playing loose of the screw pivot. r

In the accompanying drawings, Figure 1 represents a front elevation of my improved hot-air register. Fig. 2 is a, horizontal section of the same, with parts broken away, on the line 2, 2, Fig.1. Fig. 3 is a detail top view of the operating-lever and its connection with the frame of the register, the gov erning-rod and the slats being detached. 'Fig. 4 is a vertical transverse section of the lever and its pivotconnection with the supportingframe; and-Figs. 5 and 6 are respectively a vertical transverse section of the supportingframe with the operating lever and its pivot removed and a top and side view of the sheet I metalbox for retaining the nut of the screwpivot bolt of the operating-lever.

Similar letters of reference indicate corw spending parts. 4

Referring to the drawings, A represents the I I exterior supporting-framemf my improvedhot-air register, which frame is provided on opposite sides with the usual socket-recesses a for the pivots on each endof the slats B B and with lugs a, through which the fastening-screws of the open-work top or face-plate are passed. The lower ends of the slats B are provided with projecting lugs b, that are connected by a governing rod or bar 0, provided with. pivots b,

jecting lugs of the slats B, said pivots being arranged eccentrically to the pivots on which the slats swing in the frame. The governing fitting into holes in the pro rod C is alsoconnected bya pivot, lug or pin v I d. with the slot (1' of a segmental lever D, applied to a screw-pivot E on which the lever D swings when the slats are to be operated by means of the governing-rod C'and moved in one or the opposite direction, according as it is desired to open or. close the same. The screw pivot E is retained in the frame A and lever D by a screw-nutE'.

The parts so far described are well'known,

except that the arrangement of screw-pivot,

lever, nut as-shown and hereinafter described is new with me. 1

The nut E' is shown seated in a sheet metal. box F of square shape conforming to theinuti and having a central bushing f that extendsv around the shank of the screw pivot E into the hole of the lever vD, as shown clearly in Fig. 4.

I At the under sideof-thesheet-metal box F i is arrangeda circular rim or flange ffiwhich 1s concentric to the bushing and-which bears and locking surface of the frame on the top part of the shank of the lever D and exerts a certain degreeof friction on the withdrawing same, so that the lever is held in any'position to which itis placed.

To'preIvfent the axial turning of the box F,

and nut E, the same are seated in an angu-- position and prevents the playing loose of the.

same when operating the slats of the register.

The screw-pivot E is inserted through the side piece of the frame,

and the bushing of the box 0 on which the operating lever D hasits bearing into the screw-nut E and screwed into the nut until the box is tightly adjusted on the lever D. When in this detaching of the screw-nut from the screwpivot is prevented by the recessed boss of the supporting-frame, and by the fact that the lever D turns'upon the bushing and not upon the bolt, and the'screw-pivot is prevented from from the nut by the casing (not shown) in which the register frame is set. The connection of the operating-lever with the supporting-frame is not only produced by a single screw-pivot, but at the same time a frictional action is produced by the box on the lever, so that the same is prevented from wabbling and is retained in any posit-ion to which the same is adjusted either in opening a or closing the register.

When the register is in a horizontal position in the floor, the recessed boss A imparts suflicient strength to the outer frame to resist the pressure exerted by the foot on the segmental 1ever,'so as to permit the opening or closingof the register without injury to the frame or to the sheet-metal box in which the screw-nut is supported. v

I claim as my invention 7 1. In a hot air register, the combination, substantially as set forth, of the frame having the locking surface thereon, the pivoted slats, the governing rod pivotally connected with the slats, the operating lever pivotally connected with'the governing rod, the sheet metal piece that is prevented from turning by said locking surface and which has a bushing formed thereon on which the operating lever has its bearing, the securingi bolt that passes through the frame and through said bushing, and the nut on the end thereof that is, with the sheet metal piece, prevented from turning by said locking surface.

2. In a hot air register; the combination, substantially as set forth; of the frame having the recesses oted in the recesses, governing rod pivotally connected with the slats and operating lever, the sheet metal position, the

rounding the screw-pivot,-

and locking surface, the slats pivthe operating lever, the

piece that is prevented from turning by said locking surface and which is formed with a bushing on which the-operating lever has its bearing between the side of the frame and the sheet metal piece, the securing bolt passing through the side of the frame and said bushing and sheet metal piece, and the nut on the bolt.

3. In a hot air register, the combination,

' substantially as set forth,of the frame having the angularly recessed boss forming a locking surface, the pivoted slats, the operating lever,

the governing rod pivotally connected with the slats and operating lever, the metal box lying in and prevented from turningby said angular recess and having a bushing formed thereon on which the operating lever has its bearing, the securing bolt passing through the side of the frame and through the bush ng and the nut on the end of the bolt and lying in said box.

4. In a hot air register, the combination, substantially as set forth, of the frame havin g the locking surface, the pivoted slats, the operating lever, the governing rod, pivotal] y connected with .the slats and with the operat ng lever, the metal piece prevented from turning by said locking'surface and and a concentric friction rib or flange surrounding the bushing, the bolt passing through the side of the frame and said bushing, and the nut on the bolt, the operating lever having its bearing on said bushing between the friction flange and the side of the frame.

5'. In a hot air register, the combination of a supporting-frame having an angularly-recessed boss, slats pivoted to said frame, a governing-rod pivoted eccentrically to said slats, an operating-lever pivoted to the governingrod, a screw-pivot passed through a slot in the supporting-frame and the shank of the operating-lever, a nut engaging said screw-pivot, and a centrally-perforated sheet-metal box passed over said screw-pivot and lying between the operating lever and the nut and seated in the recessed boss of the supportingframe, said box having upturned flanges embracing the sidesof the nut and provided upon its underside with a central bushing suron. which bushing the operating lever has its bearin g and a raised concentric flange exerting a frictional action on the operating-lever, substantially as described.
