SASH'FASTENER.

` SPECIFICATION forming part of Letters Patent No. 272,671, dated February 20, 1883.

To all whom 'it may concern:

Be it known that I, HENRY J. ENGLAND, a citizen of the United States, residing at Falls Church, in the county of Fairfax and State of Virginia,hayeinven ted certain newand useful Improvements in Sash-Fasteners; and I (lo hereby deelare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the aecompanying drawing's and the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a certain class of sash-fasteners that loi'k and unlock the upper and lower sashes of house-windows, that will retain the window seeurely in place when closed, and will also retain them in place at any desired position when open for the purpose of ventilation; and it also relates to the Operating of each fastener separately and indepeudently by means of a single key that is removable at will by the operator, thereby preventing the windows from being rased or lowered without the key77 The principal'objeet of this invention is to prevent the slightest upward movement of the lower sash of a window without lirst Operating the fastener-[hat is, whenonly one fastener is used in a window, and that on the lower sash.

Another object of my invention is to guard against the accidental displaeemeut of the fasteners while the windows are locked.

Another object of my invention is to so construet my sash-fastener that the Operatingkey can be readily removed or inserted at the will of the operator, and that the sash-fa-stener cannot be operated without the key.

Another object of my invention is to provide a sash-fastener -for the upper and lower sash ofawndow, each of which can be operated independently of the other by a single key7 inserted through both fasteners.

I attain these objects by means of the mechanism hereinafter more fully pointed out, and described in the specification and claims.

Figure l is a face view ot' the fasteners,with key inserted through the casing of the window, with the windows removed. Fig. 2 is a side View, partly in section, showing the window- Application filed December 20, 1882. (No model) sash locked, the fastenercase, and mechanism of the fastener. Fig'. 3 is a View of the key used to operate the fastener; Fig. 4 is a detail view showing fastening-dog, and Fig. 5 is a detail view showing Operating-cam. Fig. 6 is a detail view showing the removable side of the housing.

Similarletters refer to similar parts throughout the drawings.

A represents the right-hand upright of an ordinary window-frame, and B and O represent respectively lower and upper sash sliding` thereon.

In the upright window-frame A two of my sash-fasteners are shown by face in position with the key passing through both fasteners to operate on the upper and lower sash, respect-ively, and are indicated by the letters D D'.

The key E in Fig. 1 is shown by dotted lines inserted in the casiug and through the fasteneners, by means of which either one of the fasteners ran be operated independently of the other. This key is formed with thumb and fiuger rests (t a, and with a shaft splined on the sides, or with a square, triangular, or other desirable ft rm of shaft.

Fig. 2 represents the sash-fastener as inserted in the right-hand upright window frame or casing adjacent to and locked with the lower sash of the window. Its purpose is to hold the lower sash rigidly in place, to prevent levers or other devices from being inserted between the lower cross-rail of the sash and the window-sill to force the window up, and generally to prevent the window from being raised without. first Operating the fastener with the key.

My improved sash-fastener is constructed as follows: A metallic housingor casingisformed (preferably cast) of the shape shown by seetlonal view in Fig. 2, and having one side of the same remova ble, for the easy admission and removal of the operative parts of the device.

A i'zistenirig-dog,b, is formed of metal in the Shape shown in Fig. 4-, its outer end beveled on the under side, and at a point about twothirdsits length is pierced by an elongated slot, c. The outer and upper end of said slot terminates in a circular recess, c, formed to receive a pivot-pin, d, that extends from the sides of the casiug or housing, and on which the dog b is pivoted. The inner end ofdog b is curved in the form of an arch, to loosely tit over the cain c, by which it is inoved. The extreme inner end of the dog I) is perforated to receive the end of a spring,f. The opposite end of tlie curve on theinner face of tlie dog b terminates in a sliarp projection, tl'. From this projection toward the outer end of the dog b a slightlycurved recess,c', isforined. Beyond this recess an incliiied projection,f', is forined, terminatiiig in a perpendicular face, g. The object of this peculiar formation is tliat the inner end of the dog Z) will lit to and register with tlie projections and formatioii of cam c, used to move the dog b. Cam e is formed of metal, with shoulders to fit perforated bearings iii the sides of tlie casing or housing. Outside the bearings cam e is enlarged about two thirds its way iii i'ounded form, the remaining third extending outvtard in the forin of a cnrved lip, j, having a curved recess,j', inward from the v end of the same.

On eacli side of thehousing, underneath the dog, and close to the straight face of the bevel on the saiiie, is foi'med a stop, g, the purpose of which is to aid in holding the dog b secui'ely iii place when locked, aiid the outer end ot' said dog inserted in the sash of the window. A similar stop,h, is formed on the sides ofthe housing, to prevent the cam c from being displaced by any reverse moveinent. An aperture is forined through the face of the housing for the passage of the outer end of dog b.

Through a perforation on the inner end of dogb one end of a coiled or other form ot' spriiig is inserted, the opposite end of said spring being secured to the end ot' the casing or to apin secured in the saine. By meaiis of said springfthe curved inner end of dog b is held against tlie outer face of the came, and constantly acts against Ithe inoveinent of said cam by pulling the inner end of the dog b against thev cam aiid against the pivotpin, forcing the outer end into the bnshing in the t sash.

The sash is provided with inwardly-heveled bushings i, ofsufficientsize to receive the outer end ot' dog b and permit of a longitudinal movement of said dog in the act of looking and uiilockiiig the fastener.

The window-casiiig is perforated on a line with the aperture through the fastener for the reception of the key, and is protected on its oiiter face by a bushing or key-hole.

The operation of iny device is as follows: When the device is used for the lower sash only, the bushingin the sash and the aperture in the face of the fastener-case are made to match and coincide exactly when the sash is closed, the springf, acting oii the dog b against the cam e and pivot-pin d, forces the outer end of the (log b into the bnsliings t', drawing tlie dog b down against Ithe projection g and out to the pivot-pin d. The dog b is then hcld in place by the springf, pivot-pin (J, and projections g, and by means of the beveled formation of the bushing and thevlike formationv of the projecting end of dog b the sash is securely locked, and cannot be inoved upward without first unlockiiig the same with the key E. To nnlock the fastener, iiisert the key E through perforation iii window-casing into the cam eand turn to theleft; the lip of the cam will engage with the cui've and projection e' d', force the dog against the under side of the pivot-pin, and retract the outer eiid of the dog from the sash-bnshing by tii'st raisiiig the dog ofl'from the projections gand oii' froin the pivotpin d until the pivot-pin d strikes the lower face of the slot a, when, by the further turning of the cam, the dog is moved in a longiiudinal direction nntil the pivot-pin strikes the inner end of slot c, when the| lipj, acting oii the cavity e', retracts the outer end of the dog within the housiiig or casing, wlien the sash can be readily moved. w

Then two fasteners are used jointly for one wiiidow, when desired to move both upper and lower sash for Ventilation and the lasteners are placed to be operated by a. single key, the position shown in Fig. 2 is reversed, as is the bushing in the sasli. VVhen Operating the device one hand is placed on the sash to steady the same, while the other hand operates the key. The upper sash is slightly raised while the fastener is being operated by the key, the mannerof Operating the l'astener being nearly the same in both cases.

Having described my invention, what I desiie to secure by Letters Patent is- 1. The combination, with the sash having a socket formed in its edge, of the dog having the angular slot, the spring arranged to pull the iiiiier end of said dog iiiwardly,u.nd a cain arranged to force the lower end of said dog latei'ally and longiiudinally against the tension ol the spring, and to move the dog longitudinally and laterally, substantially as and for the purpose set forth. l

2. The coinbination, with a dog having the intermediate angled slot, c, and the projection (1/, having the curved recess e', ot the housing or casing having an apei'ture tor the passage of the looking eiid or' said dog, the pin d, extending through the angled slot, the spring arranged to force the lower end of the dog lnwardly, and the cain having the lip arranged IIO IIS

to play against the wall of said curved recess, v

iial movements, essentially as and for the purpo e set foi'th.

Iii testiinony wlicreof I affix my signature in presence of two witnesses.
