HENRY HOWARTH, OF DETROIT, MICHIGAN, ASSIGNOR TO THE HOWARTH REVERSIBLE SASH AND SASl-I CENTER COMPANY, OF SAME PLACE.
TRANSOM-PIVOT.
SPECIFICATION forming part of Letters Patent No. 499,922, dated June 20, 1893.
' Application filed November 5, 1892. Serial No. 451,081. (No model.)
To all whom it may concern.-
Be it known that I, HENRY HOWARTH, a citizen of the United States, residing at Detroit, in. the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Window-Sash Centers, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention consists in the peculiar construction of a center comprising two disks, upon each of which are arranged opposite radial'arms tapering from their points of con nection with the disk toward their outer ends,
being preferably substantially the width of the rabbet, and the ends formed substantially on the arc of a circle, all as more fully hereinafter described. A In the drawings, Figure 1 shows the two parts of my sash center in perspective. Fig. 2 is an elevation of the center showingthe two parts applied to the frame and sash, and showing in dotted lines the different positions of the sash in relation tothe frame. Fig. 3
is a central, longitudinal section through the sash center closed. Fig. 4 is a vertical, central section showing a slightly modified form of disks or hubs. Fig. 5 is a cross section on line a" a: Fig. 3.
The sash center comprises two substantially like parts A and B, each part comprising a central hub or disk 0. and oppositely extending tapering radial arms b. The hub of the part A is preferably made convex, as shown at c and the hub of thepart B is made correspondingly concave, as shown at d, the object of this being simply to make a sight and dust proof joint. Instead of making a concavo, convex joint any other construction may be 40 employed which will break the line of vision between the hubs or disks at their pivot points, such for instance as is shown in Fig. 4, in which I have shown corresponding circular grooves e in each hub, in which a ring f is adapted to engage, the ring extending half into each hub. The arms I) are of a thickness greater than the thickness of the hub. This additional thickness I usually call an 0E- set 6, the lower end being suitably cut off to allow it to turn about the hub of the adjoin- 5o ing part when the two are placed together.
it are central apertures in the disks or hubs. The sides of the arms I) are bounded by lines which are substantially radii of the hub and the ends of the arms are formed substantially concentricto the hub. The parts being thus constructed, the two parts are placed together, the convex hub engaging into the concave portion of the other hub, and a single securing screwi passes through both hubs into the stile of the window sash and secures the parts together forming the pivot upon which the frame turns. The window is then turned at an angle to the sash, as shown in Fig. 2 and the securing screwsj are driven into the frame, the opposite arms I) on the frame member being secured at their ends substantially coincident with the ends of the rabbets 7c. The sash being now hung it will freely turn about its pivot and the interlocking faces of the hubs will always maintain a light and dust proof joint, while the overlapping offset 9 will always maintain a tight joint to the end of the rabbets. These olf-sets I form of less than the thickness ofthe hub and then when the centers are secured in position flush with g the faces of the rabbets, the play which will thus be given will indicate the amount of play between the sash and'the frame.- This is illustrated in Fig. 5 which is a cross section on line 00-41; in Fig. 3. This construction enables me to secure both members to the sash and then when the two members are thus secured to swing the windowin the frame, greatly simplifying the hanging of the window and ing radial arms extending on opposite sides thereof, of over-lapping offsets g on said arms, substantially as described.
3. In a sash center, the combination of the 5 parts A and B, comprising a hnloa having a convex inner face and the opposite radial extending arms, and the part 1) comprising the hub having a corresponding concave face and corresponding oppositely arranged radial arms, said arms-being inclined on their oppo- IO site sides from their outer to their inner ends substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
HENRY I'IOWARTH.
