'To aan wnoM'I MAY Cercami; Y' i i A i A ABe it known that I, -ALoNzo T. Boor, of the city'ot Galesburg, Knox couaty,vand State of Illinois, have invented anew and useful Improvement in Window-Sash Stops; and do .hereby declare the following descrip; ltion and accompanying drawings are sullieienthto onoble'anyperson skilled in the art or science to which it most rapglyeppertana to malce and use mylsaidin'vention .or improvements without fnrther'invention'or experiment.

Theinature oi'myinvention and improvement consists in'asixnple and novel methodof suspending the sash at any?` desired, upon itsbein g raised by the antpinatic-action of an India-rubber or gatta-porche. 'roller or its equ'ivxb Ichi, vapplied within an incl-ined or angular-ly vformed -b'ox attached tothe faeeside 'of the s'ash by means of a plate connecting therewith, and hovingthereon avpeculiar'ly formed leverV for controlling the said roller-while the sashis being lowered; the said lever not onli-performing this function, but serving the purpose of a fastf einer for securing the Vsash atvnightor otherwise;

i The construction and operation of the device arefully explained in the descriptionbelow, and likewise ills' A trlz'ted in the 4accompanyingdrawings ity-the following figure,I viz Figure 1 is a. front view' of a window frame and sash therein, showing the application ofthe device thereto.v

` A represents the window frame, B the sash. The box'jis maigi'ly'aplate construetedoi an inclined or angular form, a, and suiciently curved around from the angle .thrdoftdyreceive atop plate, which is fastened i thereto, 'and rhode to conform to the angle and"curve of the' plate," f slightly sro-es to ferm a enge thereon onderhandthe durved partot placed with the angle of the inclination aof" the samey down from the edge of, the plate b, and securedthereto by thel flange above ,mentioned being soldered thereon. If deemed desirable the plate and the box connected therewith may be east whole. Before' the device as thus constructed is applied tothe sash, theroller c, (seenin dges of lthe plate a are turned over dotted lines,) of rubber 4oi' its equivalent, is introduced within Vthe angularly formed boil through the open side. i

The device is then attached to the face sideof the-sash," at or nearthe top, and ilnsh with the edge of the same, by two screws d, having finished circular washer plates under their heads; In' close proximity to the angular-'ly formed box is alever, C,one portion of which 'lever is made straight, and the other curved'or made of ahooked form. It is placed obliquely below theV inclined box', as will be observed in' the top sash, and secured .on the top ofia circular washer plate, the same as placed under the screw heads by the screw which screw serves as f a. 'pivot for the lever to operate on, as well als-fastening it and the plato 'to the sash. A slot `e is made in the inclined side of the 4box to allow the introduction of the curved part of the lever through the saine, soV as to enable the lever to control the roller whilerthe sash is being lowered. In the jamb or head ofthe same are two notehesf, in which the straight ends of the levers are inserted to serve thepurpose of fastening the sash whenv desired, (see the same in red lneslivn g. 1.) The leveren the lower sash is placed obliqirely above the inclined box to enable-it to be used as n fastener,` which could not be done well, -as will hepppar'ent, in a position below as in the top sash. v

i' Oper-ation..

Thofperson wishing to 1ower' thc upper sash, rst removes the lever'from its fastening position with one hand, andthen tnxns the curved part of the s ame into the inclined boi; 'through the slot, over andren the roller,

and thus holds the roller at tho larger'pait of the angle ofthe inclined box, while withV the other-hand he lowers A tho sash, and when reaching the p oint desired, he lets go-of the lever and sash. i -'lhe sash consequently, frdm: its own gravity, becoming depressed," produces friction` to the roller means of the. inclined side of the bog, andthe .side of the jamb or bea'd of the same aetingthereon, which friction thas produced impels the rollerto,

near the apex or smaller part ofA the anglo of vthe inclined boa, where the weight of the sash pressing down .on

it holds it fast. The snsh, by reason of the roller traversing the inclined side' of the box,is forced firmly againstV the opposite side o'f the jamb, which in connection withthe position of the roller attained from .the movement thus made, and as abovedescribed, the sash is thereby held and snspended without any possibility of its slipping, so that it' force was even exertedit could not be brought down, the sash becoming wedged as it were betweenv thnsdes of the jamb by its own weight acting on the roller. 0n the person raising the sash, the roller drops me. The boxtlrus far soV formed isV 2 emo to its original positon in the boxl.' The sash is then ready agi te be lQxvei-e on 'the manp'ulation' of the lever en the roller, as above alluded to. The same operation attends vche raising and werling ofthe lewer sash.`

Having thus fully described my invention, what I claim therein asvnew, midjesixeV to secure by Letters Patent, isv l n." l The curved lever C, as constructed :1v-nd "arrnged t'o operatie on theV pivotal, ,in lcombix1'x a.ftit l1 ivfrhkthe righte" angled box a, (foi the control of the roller therein and its combiuatnwth the notches f to serve as festeper; substantially in the manner as herein described. l l
