THON-AS HENRY KANE,y OF 'YOUNGSTOWN, OHIO, ASSIGNOR TO TRUSSED CONCRETE STEEL COMPANY, 0F DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

wINDoW-FBAME.

Application led July 1,

Beit known lthat I, THOMAS H. KANE, a' citizen of the United States, and a resident of Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Window-Frame, of which the following isa specification.

f Thi invention'relates to metal frames-for windows,J particularly the construction. of the side bars of slidable sashes, and to the construction of thevertical'members 'or mullions between the sashes; audits object isto provide a strong construct1on which may be` readily built up from standard rolled bars with the-aid of few and simple tools.

yThis invention consist-s in the combination of bars of novel cross sections united by novel bolts, together. with sash side bars of novel cross section.- J While not limited to sash constructed accordin .to the former Patent No. 933,908 dated eptember 14, 1909, reference is made to this patent for the details of a sash whichy is adapted for use with my-present invention.

In. the accompanying drawings, Figure 1 is an loutside elevation of sashes, andmullions embodying this invention. Fig. 2 is an enlarged view, of a portion of IFig'. 1 at the4 point A. Fig. 3 is a similar view at the point B. Figs. 4, 6 and 7 are 'sections on the linesl44, 6 6, and 7-7 of Fig. 1,

' respectively on a larger' scale. 5 shows an arrangement of three sashes in one frame. Fig. 8 is a plan and Fig. 9 an end View of the bolt employed in tli1s construction on a large scale. y

Similar reference characters refer to like parts throughout the several views'.

As in the former patent, the sashes may be built up with 'side' and end bars formed of special rolled vbars 1 of I beam pattern, having their flanges 2 rolled down onto `the edges of the interior bars 3 and the guide bars 4. 'These latter have guide flanges 5 slidable betweenthe bars forming the mullionsx. l

The structure shown in Figs. 1 and 4 is designed for upper and lower slidable sashes, but the construction may be duplicated as desired, that shown in Fig.v bei'ng designed for three slidable sashes. In Fig, 4, two rolled sections'are shown, the smaller being used three times. This section is Specificatien of'lietterrs Patent. ,-nPvatented Aug, 22, 1911.

formed of a flat plate 6 having a low' central .rib 7. The other sectionlhasa flat plate 8 mit adjacent sashesto-pass each other as shown in the ligure. Holes 10 .in pairs are punched through the flat plates, one of each pair on either side of the central rib, preferably of the exact form of the cross'section such exactness lis not necessary, being desirable however to make a goodappearance.

The bolt is preferably formed by bending a bar-of steel, flat on one side and curved to the desired circle onthe other, as shown in Figs. 8 and 9, and threading the end. Or if desired, a slot may be cut into an ordinary bolt. The bars are then assembled as indlcated in'Fig. 4 and the bolts introduced, one side 11 extending lalong one side of all the ribs 7 and 9. Anut 12 is then screwed on, drawingjall the bars' together intol a rigid structure of great stiffness. The heads 13 are preferably on 'the' Weather side.

l The larger f bars arel machined at their ends by cutting away the plates 8, leaving tongues 14, which tongues extend into slot-s in the sill plates 15' and lintel plates 16. If

and lintel plates and between the outer plates 6. The guide flanges 5 on the guide bars of 'up and down as' far as the outer edges of similar flanges 18 on auxiliary top and. bottom bars 19 of the sashes. As shown in Fig. 6, these flanges 1 8 extenddown within the angle bars and assist in making tight joints. The upper and lower ends of the flanges 5 of they guide, bars completeithe corners of the sashes.

By merely perforating the dat plates 6 and 8, little of the strength of the bars forno ing the mullions is lost pfor when considered as beams with reference to stresses in lines parallel to the window, these holes `are near the neutral axes where the remaining metal is of ample strength,v When considered with reference to wind pressures, the central ribs are entire from top to bottom and are not affected by the perforations .of the plates 6 and 8. It is therefore unnecessaryto roll strength lost by perforating.

Fig. 6 were turned upside-down, it wouldv be a cross section on the line 8-8'of Fig. 1.

Angle bars 17 may be secured to the'` sill the sashesare preferably formed to extend t bars with additional metal to provide` and a high rib 9 of suflcient height to perof the metal 'forming the bolts, although space the plates to form guidey ways `for window sashes, and guide flanges on the` sides of the sashesl extending into the guideways of the mullion.

2. In a mullion for guiding window sashes the combination of bars in pairs, one pair for each sash, lone `bar of each pair formed with av rib of sufficient height to space` the bars to form guide ways for' the sashes, and the bar of the pair which faces the adjacent pair having a rib of suiiicient height to permit such guided sashes to pass each other,

and bolts to unite the bars.

3. In a window construction, the combination with vertically slidable sashes, of upright n iullions comprising narrow vertical plates in pairs, one of the plates of each pair formed with a longitudinal spacing rib of such height that the adjaccntport-ions of the sashes mayv freely slide between the plates, one of the plates of'adjacent pairs having an integral longitudinal `rib of such height'that adjacent sashesmay pass each other, and means to holdthe plates forming the mullions rigidly united.

4. In a window construction, the combination with the sill and lintel, of a mullion between thesanle comprising narrow plates in pairs, one of the plates of each pair formed with a longitudinall spacing rib osuch height that the adjacent flangev of a sash may freely slide between the plates,one lofthe plates of adjacent pairs having alongitud-4 nal rib of such height that adjacent sashes may pass each other, means to hold the plates rigidly united, angle bars secured to the sill and lintel, flanges formedon the sides of the sashes `to slide between the plates of the mullion, and anges ony the bottom of the lower sash and the top of the upper sash to .move into sliding contactwith the angle bars on thel sill andlintel respectively. -v

In testimony whereof I have signed this specification in the presenceof two subscribing witnesses.- j
