SPECIFISATION forming part of Letters Patent No. 320,161, dated June 16, 1885,

Application filed March 6, 1885.

To all whom it may concern:

Be it known that I, CHARLES It. NELsoN,of the city, county, and State of New York, have invented certain new and useful Improvements in Devices for Adjusting and Securing Vindow Stop-Beads, of which the following is a full, clear, and exact description.

This invention relates to devices for adj usting and securing window stopbeads similar to the device for such purpose on which Letters Patent No. 49, 660 were granted to \Villiam Shaw, August 29, 1865, and in which a metal box or thimble having an elongated slot was inserted into the stop or bead and ascrew entered through said slot and passed into the jamb, whereby provision was made for adj nsting the bead or stop relatively to the sash to maintain the requisite fit or tightness of the sash.

The invent ion consists in a special construction of the slot-ted box or thimble for use in connection either with a fiat or round headed screw, including, in certain cases, a roughened washer, to prevent slip after adjustment of the bead, allsubstantially as hereinafterdescribed, and whereby certain ad vantages, ashereinafter specified, are obtained.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate con responding parts in all the figures.

Figure 1 represents a perspective view of a window-frame and window-sash, in part,with one of the stop-beads in place and having my improved adjusting and holding devices applied. Fig. 2 is a horizontal section of the same, and Fig. 3, a further horizontal section, in part, with a round-headed screw and roughened washer applied. Fig. 4 is an outer face view of the slotted box or thimble, and Fig. 5 an under view of the roughened washer.

A is the box or thimble, having an oblong or oval slot,b, in it, and having its exterior configuration that of the frustum of a cone,or with plane tapering sides 0, contracting from the outer face of the thimble inward, and without any special exterior projections to seat it and keep it from turning when in place. The hole (Z in the stop-bead B is bored cylindrical, and will be made to conform to the tapering shape of the thimble by drivingin the (No model.)

latter, which will serve to securely jam or hold the thimble in place.

By this construction of the box or thimble it is prevented from being drawn by the screw 0, which passes through the slot 1) and enters the jamb below the outer surface of the bead, and said box or thimble is more easily applied than the box or thimble in the patent l have hereinbefore referred to,which was made with parallel exterior sides, and consequently required an outer face flange or rim to seatit, or prevent it from being drawn below the outer surface of the bead, and with a side rib to keep it from turning. This outer flange was liable to breakage in driving the thimble to its place in the bead, and it broke the fiber of the wood at the edge of the aperture in the bead, and the side rib 011 the thimble made the thimble difficult of adjustment to the hole in the bead, it requiring a cut to be made in the wall of the hole for reception of the rib. By using an externally plain tapering thimble, A, howev r, the box or thimble will be so securely held or jammed to its place that it will require no special means or projections to keep it from being drawn by the screw below the surface of the bead and to keep it from turning in the bead,thus makingit much easier of application and preventing all breaking of the wood.

By this construction of the thimble A, too, and by beveling or counter-sinking the outer marginal sides of its oblong slot I), as at e, or by so internally beveling it for a portion of its depth and making it of a reverse bevel, as, at f, for the remainder of its depth, to prevent the shank of the screw from binding or catching on it, a flat-headed screw, 0, as shown in Figs. 1 and 2, may be used, so that the head of the screw may be kept flush with the surface of the bead B, and no cutting will be necessary for the head of the screw in a mosquito-netting frame when applied to the window, but said frame may be seated flat and close to or over the stop-beads.

My improved box or thimble, too, may readily be fitted to a hole of not more than half an inch exterior diameter, which is as large a hole as can well be used in stop'beads of ordinary dimensions, instead of, as in the box or thimble of previous construction, re-

quiring a circular depression to be made in its surface the depth of the round-headed screw used, and which required to be of much larger diameter to allow of a sufficient adjustment of the bead to the sash.

Where a round-headed screw, 0, is used, as shown in Fig. 3, then a washer, D, Figs. 3 and 5, maybe applied over the outer surface of the thimble, which washer, through which the shank of the screw passes, is made smooth on its outer surface, but scored or roughened, as at g, on its inner surface, to prevent the head from slipping when adjusted. This modification will be found best adapted for large or heavy window frames and sashes, and where a mosquito-netting frame is not designed to be used. The box or thimble A in Fig. 3 is of the same construction as in Fig. 2, so that the same castings will answer for both modifications.

The general utility of the device is the same as in previous constructions of it,namely, in providing for the ready removal of one or both of the stop beads or strips should the sash stick after painting, so as to interfere with the elevation of the sash, also providing for setting up the beads in case the sash becomes so loose as, .in the case of aheavy wind, to produce a constant rattling. One half-turn, or thereabout, of the screws admits of the stop-beads being readily adjusted to the sash.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

1. In devices for adjusting and securing window stop-beads, the box or thimble A, having its exterior sides, 0, made tapering, as described, and having its interior I) of oblong form, with a countersunk outer marginal surface, e, for usein connection with the screw 0, and with the stop-bead D andjamb of the window, substantially as specified.

2. The combination ofthe roughened washer D with the externally-tapering box or thimble A, having its interior passage, b,of oblong form, substantially as and for the purposesherein described. I

CHARLES R. NELSON.
