H. T. WALTON PIVOT WINDOW May 16,
Filed Sept. 25. 1931 INVENTOR- Hawani .Tl l alz'fozz,
ATTORNEYS.
EL a? 6% Patented May 16, 1933 I STATES 'A rsr rice HOWARD WALTON, OF COLLINGSWOOD, N EW JERSEY, ASSIGNOB T DAVID LUPTONS SONS COMPANY, OF PHILADELPHIA, EENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA PIVOT wrnnow This invention relates to windows with pivoted sashes; and it has reference more particularly to swin ing sash windows of the type described in [15. Patent #1,584,970, of
May 18, 1926, granted to Charles Berger, wherein combined hanger and weathering strips on contiguous frame and sash rails and disposed respectively to opposite sides of the pivot axis, aiford ears for passage of a pivot bolt.
The object of my invention is to provide in connection with such pivots, simple and easily incorporable means capable, by cooperation, of maintaining regulatable frictional restraint against free movement of the sash, so
that the latter is efiectively held from displacement under wind pressure in any desired position of adjustment. 7
In the attached drawing, Fig. I is a fragmentary edge view of a swinging sash window at the pivot region, conveniently embodying the present invention.
Fig. II is a fragmentary elevation viewed as indicated by the arrows II-II in Fig. I.
Fig. III is a view like Fig. I showing the pivoted sash of the window swung partly open.
Figs. IV and V are cross sectional views taken, respectively, as indicated by the arrows IVIV and VV in Fig. I; and,
Figs. VI and VII are perspective views of component parts of my improved frictional sash restraining means.
Referring in greater detail to the drawing,
I have partly shown at 10 one of the side or jamb rails of the frame of the window; and at 11, the contiguous side rail of the sash, which, in this instance, is swingable on a horizontal axis after the manner shown in Fig.
III. Both the frame and sash rails 10 and 11 are formed from rolled or extruded bar metalwhich may be steel for examplehaving the typical T-cross sectional configuration shown in Figs. IV and V. When the window is closed, the rail 11 of the sash occupies the same plane with the amb bar 10 of the window frame with provision of a slight I lateral working clearance between them as at 12 in Figs. IV and V. Riveted to the sash 59 rail 11, above the swinging axis of the latter,
is a combined hanger and weathering strip 13, of channel cross sectionlikewise of steeihaving ashort flange 13a to lap the clearance 12, and a longer parallel flange 13?) to lap the inner edge of the main web of the frame rail 10, see Figs. IV and V. Asimilar weathering strip. 14 is riveted to the frame rail 10 below the swinging axis of the window, the position of this strip being however reversed, so that its short and long flanges 14a and 14?) respectively lap the clearance 12 and the inner edge of the main web of the sash rail 11. At the region of the pivot, the contiguous ends of the strips 1 3 and 14 are arranged in interlapping relation as shown in Fig. II, formed integrally with lateral pivot ears 17 and 18, respectively, see'Fig. II also, the said ears being pierced for passage of the shank of the pivot bolt, which latter is indicated at 19.
For the purpose of inducing frictional restraint in the pivot in accordance with my invention, I provide means including a pair of washer members 20 and 21 whereof one is shown in perspective in Fig. VII, and a clamp yoke member 22 which is likewise shown in perspective in Fig. VI. The washer members 20,21 are identical as to size and configuration, but one of them is struck from steel and the other from a softer metal like brass or bronze. As shown in Figs. IV and V, the washer members 20 and 21 are formed with pierced ears 20a and 21a to correspond with the ears on the weathering strips 13, 14,
and with angularly offset portions 20?), 21b
to lit the corresponding angles of the said weathering strips. The washer members 20 and 21 are accordingly held against independent movement relative to the weathering strips, with their ears 20a, 21a lodged between the cars 17, 18 when the sash is swung on the pivot 19. For further assurance against displacement, I preferably secure the washer members 20, 21 to the strips 13, 14 by means ofrivets 23,24. 1 T he clamp yoke member 22, it will be noted, has a short extremity 22a and a long extremity 22?), the short extremity being pierced as at 220 for free passage of-the shank of the pivot bolt 19, while the longer extremity is bored and tapped as at 22d for engagement by the threads of the bolt shank, see Fig. V. Between the short extremity 22a of the yoke member 22 and the ear 17 of the weathering strip 13 I place a plain annular washer 25, made, like one of the special washer members 20, 21 from brass or other soft metal.
With the parts assembled, the yoke membar 22 spans or straddles the grouped pivot ears 17,18, 20a and 210, with the straight edge of its longer extremity 22b resting firmly against the inner face of the weathering strip 14 on the frame rail 10, the yoke member 22 being thereby prevented from rotating independently on the pivot bolt 19.
Any desired frictional restraint for the sash may obviously be predetermined in the pivot connection through rotative adjustment cf the pivot bolt 19, while the effectiveness and longevity of the connection is insured through use of different metals in the fabrication of the special washer members 20, 21.
Having thus described my invention, 1 claim:
1. In a metallic pivot window having contiguous frame and sash rails of angular cross section with relatively reversed combined channelsection hanger and weathering strips embodying flanges of different widths; means to form in conjunction with pierced lateral ears respectively integral with the weathering strip, a friction pivot connection including a pair of washer members of relatively hard and soft metals fixed in relation to the said frame and sash weathering strips and having ears disposed between those of the said strips, a clamp yoke member straddling the several pivot ears and having an extremity thereof engaging the Weathering strip of the frame rail, and a headed pivoted bolt with its shank passing free in one of the extremities of the clamp yoke member and in the several ears, and taking into the other extremity of the clamp yoke member.
2. In a metallic pivot window having contiguous frame and sash rails of angular cross section with relatively reversed combined channel-section hanger and weathering strips embodying flanges of different widths; means to form in conjunction with lateral ears respectively integral with the weathering strips, a friction pivot connection, including stepped washer members of relatively hard and soft metals configured to fit the angles of the said frame and sash rail weathering strips and having pierced ears to engage between. those of the said strips, a clamp yoke member straddling the several pivot ears and having an extremity thereof engaging the weathering strip of the frame rail, and a headed pivot bolt with its shank free in one of the extremities of the clamp yoke member and in the several ears, and taking into the other extremity of the said yoke member.
8. In a pivot window having contiguous frame and sash rails of T-cross section, weathering strips of angular cross section secured respectively to said frame and sash rails at opposite sides of the pivot axis, means to form in conjunction with lateral ears respectively integral with the weathering strips a friction pivot connection, said means consisting of washer members struck from relatively hard and soft metals to angular configuration to fit the angles of the weathering strips and having stepped ears to engage between those of the said strips, a clamp yoke member to straddle he several ears and having an extremity thereof engaging the weathering strip of the frame rail, and a headed pivot bolt with the shank thereof free in one of the extremities of the yoke member and the several ears, and taking into the other extremity of the said yoke member.
In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 16th day of September, 1931.
HOWARD T. WALTON.
