METALLIC WINDOW-SLIDE.

SPEGIFICATION forming pa.rt of Letters Patent N0. 579,631, dated March 30, 1897. Application filed January 20, 1896. Serial N0. 576,183. (N0 model.)

T0 all wh0m z'25 may c0ncern:

Bc it known that I, WILLIAM ZUPPANN, a citiz cn of the Unitcd Staates, residing at farsaw, in thc county 0f Haneock ancl State 0f lllinois, have invented a ncw and useful Metallic VVindow-Slide, of Which the following is a specification.

This invcntion relates to an improvcmcnt in metallic window-slicles f0r windows, sereens, &c.; ancl tl1c objcet in view is 130 proviclc a simple ancl efficieht guiding strip o1 slide which may be usecl upon any winclow, which wilhprotect the window-sashes from swelling and warping, and Which is constructecl in such manner that it may be easily and reaclily 1 cmovccl whenever it becom es ncccssary to takc out the window-sashes, screens, &c.

A further object of the invcntion is to con-' struct such slide in a manner that Will adapt it to receive and engage a spring-catch carriecl loy one o1 both of thc wincl0w-sashcs 01 tl1e scrcen-frames.

l/Vith Ehe above objects in view the invention consists in certain novel fcatures and details 0f construetion and arrangement 0f parts, as hcreinafter fully clescribed, illustrated in the drawings, and finallypointcd out in the claims.

In the accompanying drawings, Figure 1 is a perspectivc view of a sufficient portion of a window framc, sash, &c., to illustrate the application of the present improvement thereto. Fig. 2 is an enlargccl detail horizontal section through tl1c sa1ne. Fig. 3 is a detail vcrtical section through the window-sill and lower rail of a sash. Figs. 4 to 8, inclusive, show different forms of slides. Fig. 9 is a detail perspcctive view showing the groovecl metal strip applied to the side rail of a window-sash.

Similar numerals of reference designate corresponding parts in tl1e several figures of the drawings.

Referring t0 tl1e accornpanying clrawings, 1 designates a window frame 01 casing which for the purposes of thc presentinvention is left smooth upon its inner surfacc, the usual stops 01 guiclin g strips 01 beads being omitted. In lieu of the usual wooden stops 01 beads I construct a spccial slirle, as inclicated at 2. This slide is formcd of sheet material, preferably metal, in the form of strips corresponding in length to the height and Width of tl1e window-casing. Bach strip is forrned at 01 adjacent to its central portion With a longi tudinal rib 01 guide 3, forrned by bending 01 recurving oho metal upon itsclf at such point and extcnding the edge portions 4 at 1'ight angles to such rilo po1t-ion and in alincment With each othe1. One 0f the edge portions4 0f the strip 1's provided With a series 0f perforations 5 for the reception of thc retainingscrews, and the remaining edge portion upon the opposite side of thc 1ib is formed With a scries of open transverse slots 6, extending at rigbt an gles t0 saicl rib ancl adaptccl to receivc theheads of other retaining-scrcws, as shown.

By folcling the mctal to forn1 the rib 3 and providing the open slots 6 the said rib may expand and contract, and by reason of its elasticity Will yieldingly and snugly fit the grooves in the sash ancl prevent the Same fro1n rattling, ancl also compensate for wear between thc parts, while at the san1e time saicl slots willpermit thc slide to be removed simply by looscning thc screws, as hereinaf ter clcscribed.

A numloer of perforations 01 sookets 7 a1e formed in o1 through the central longitudinal 1'ib 3, the san1e being adaptcd to receive the inwarclly-projecting extrcmity of a lock-pin 8, attachecl 130 a spring 9, secured, preferably, to oho inner surface of onc of the side rails 0f thc sash, tl1e said spring bcing proviclccl With a button or finger-grasp 10, whereloy the saicl spring may be clrawn away fron1 the sash ancl thc point of the pin removecl from engagemcnt With the perforations 01' sockets 7 in the slide.

The slides 0r strips above described are secured in the manner referrecl to 130 thc inner surfaces of the sidcs, top, and sill of anywindow-casing, and While the upper ancl lower slides are preferably macle continuous or extencled in one piece the entire Width 0f the casing the vertical strips 01 slides are preferably macle cach in two sections Which correspond to the height of the winclow-sashes, such arrangement facilitating the removal of the slides and window-sashcs when necessary. Each of the winclow-sashes, and the screenfran1es also, Wl1erc such are uscd, is fo1mcd with longitudinal grooves in the outer edges of its side, top, and bottom rails, the saicl groovcs corresponding t0 and adapted 130 fit IOO over anti slide upon tl1e ribs 3, 01 the said grooves me made slightly lmger, so as t0 re ceive tl1e U-shaped 01' hollow rib 11 of a strip 12, secured to each of the side edges of the sashes and t0 the top and bottom edges thereof, according as the sash is oho upper 01 lower ono. The use of the strip 12 prevents the wetting of the edges of the sash and the cousequent swelling 0f the same and the binding of the sashes within the fra1ne. This enablos the sashes so be moved easily up HDd Clown and renders it possible to make such a close-fitting engagement between the sashes and the window-frame that the weather will be effecoively excluded and all rattling of the sashes obviated.

When it is desirod so ren1 ove the sashes f01 any reason, they nmy be 1noved upward, so as to expose oho lower retainingscrews passing through the perforations 5 of tl1e slicles. Such sorews are then removed, afl1er which oho positions 0f the sashes a1e reversed and the upper corresponding screws removed. This will allow he sashes 120 be drawn inward, an l oho slides 2 Will be clrawn out of engagement With tl1e outer retaining-screws, which hzwo thoir heads in engagement with the open slots 6 desoribed. The sashes may be replaoed by reversing this operation.

In Fig. 5 I lmve shown how the slicles may bo macle in a slightly-clifferent fonn, in this case Ehe longitudinal rib 3 being hollow am]. of reetangular cross-sectional shape. In this case also, in lieu 0f the perforations 7, notches 13 n1ay be formed in the rib f01 i;he recepblon of l;he lockpin 8.

Figs. 6 anal 7 show, respectively, the rib 3, made in V sha-pe and in U shape in crossseotiou. In will bo understood filmt in oho employmont of either of the modified fonns 0f llbS tho srip 12 will be oorresponclingly altorocl as t0 tl1e shape of its hollow 1ib, so as to aclapt it 130 fit over ancl slide upon the rib 3.

If dosired, instead of providing a separate and inependen sot of slides for each sash a single seo may be employed, the same being provided wiuh two 01 three 01' more ribs, as indicated in Fig. 8, according 130 the nun1ber 0f sashes 01 screen-frmnes employed.

II; will thus be seen that {L very simple, inexpensive, and efficienl; strip is obuained, which will effeotively exelude wind, min, &o., Which Will admit of the ready removal of the sashes, and which Will, in connecion with the spring-misch 011 each of oho window-sashes 01 soreen-frames, enable tl1e latter to bo hold at any desired height. It Will be appareni; thao the positions of. the strip 12 and slicle 2 may be reversecl, the strip 12 being applied to.the window-fmme am]. the slide 2 to nhe sash; also, that any forn1 of sash-lock may be employed in connection with the improved strips or slides.

Changes in the forma, proportion, zu1d mi1101 details of construction may be resortecl t0 without depavting from 11110 spirit 01 saorificing any of the advantages 01": this invention.

IIaving thus described the invent-ion, what is claimed as new isl. A slide f01 window-sashes, &o., eonsisting of a metal strip creased lengthwise and folded upon it-self t0 form a longitudinal and laterally-expansivo i'ib, one of the edge portions of the strip being extended substantially a1; a, 1'ight angle to such rib and provided als intervals with slots running at right angles 130 the rib am]. opening 0ut ab the edge 0f the strip, wherebyuhe slide is ma le removable and the rib allovvod to expand and contract, substantially as desoribed.

2. 'lhe herein-described slide, consisuing 0f 21 strip of sheeu metal creased lengt-hwise ab different intervals between its side edges to form a series of longitudinal 1ibS f01 engaging uhe window-sashes und also a screen-frame 01' blind, ll6 edge portions 0f the strip beinglocatecl in the szune plane and one of said portions having inclosed perforauions while the remaining portion is provicled With open slots extending ab righu angles t0 said 1ibs, substantially as and f01 the purpose deseribed.

In testimony filmt I claim tl1e foregoing as my own I havehereto affixed 1ny signature in ehe presence of tw0 witvnesses.

WILLIAM ZUPPANN.
