May @y 3951 B. A. QUINN 2,55L850 sAsH LIFT Filed oct. e, 1945 Patented May 8, 1951 UNITED STATES ENT OFFICE 3 Claims.

My invention. relates to an improvement in sash liit wherein it is desired to provide a simple and attractive handle by means of which a sash may be lifted.

In the past it has been common practice to either mortise a recess into the sash and cover the aperture with a metal shell or else to secure one or more handles to the inner surface of the sash. The first of these structures has been seldom used, in recent years due to the added cost of mortising the sash. The mounting oi handles on the sash is disadvantageous because the attaching screws are usually Visible and further because of the dif'culty found in painting the sash. lf the sash is painted with the handles in place some of the paint is often spread upon the handle. On the other hand if the handle is removed before painting the screws are apt to he loose when the handle is again applied.

It is an object of the present invention to provide a sash pull which is simple and attractive in appearance and which may he removed when desired without the previously encountered dir"- culties. It is also my object to provide' a sash pull which may be easily applied and which requires the use of no unusual tools.

.A ieature of the present invention resides in attaching a sash pull to a sash by means of anchoring screws which extend into the sash and remain permanently place. In painting the sash these screws may become coated with paint, but this fact involves no special difficulty as the screws are concealed when the sash pull is in place.

A feature or the present invention resides in the provision of a sash pull comprising a casing of sheet metal or the like which is resiliently secured to enclose a pair spaced supporting screws extending into the window. rlhe casing is so constructed that it is securely held in place and withstand the strain necessary to raise or lower the sash. At the same time, however, the casing may he readily removed by prying the same ori of the projecting portions of the supporting screws.

An added feature of the present invention resides in providing a means for determining the proper location position the projecting screw portions. The sf* ys are provided with a flange or shoulder entelindcate the proper depth to which the screws may be inserted.

A further feature ci the present invention rcsides in the provision oi a sash pull which cornprises an enclosure having an open side which ng about the same so as to l in operative position lies against the inner surface oi the sash. As a result the sash pulls may be easily cleaned and maintained in their original attractive appearance.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.

In the drawings forming a part of my speciiication:

Figure l is a plan view of my sash pull in place upon the sash.

Figure 2 is a bottom perspective View of my sash pull showing the method of removal thereof.

Figure 3 is a sectional view through my sash pull, the position of the section being indicated by the line 3--3 of Figure l.

Figure 4 is a sectional view through the sash and sash pull, the position of the section being indicated by the line 1l-i of Figure l.

Figure 5 is `a View similar to Figure 4 showing a slightly modied form oi construction.

The sash pull A is illustrated as mounted upon a sash B, only the lower portion of which is illustrated in the drawings. The sash B may be of any desired or preferred type, but is shown as comprising the lower sash oi a double sash window which is vertically slidable in a window frame not illustrated. The sash B may support the window pane i9 in the usual manner and the sash pull A is employed for lifting or lowering the sash.

The sash pull A is mounted upon a pair of spaced screws il which are of special design and construction. The screws I i comprise a threaded end l2 which terminates at a shoulder I3 separating the threaded portion l2 from a reduced diameter shank l. The shank lil connects the threaded end i2 with an elongated head i5 which is preferably slotted at it for reception of a screw driver or like instrument.

The screws l l are spaced a predetermined distance apart. in order to insure the proper position of the window pull, I ordinarily employ a block or jig having spaced holes therein which block is placed upon the window sill at the proper distance from the frame. I then drill through the spaced apertures in the jig and into the sash B in order to properly space the guide holes and the screws li. The screws il are then threaded into the window sash until the shoulders i3 thereof lie flush with the inner surface of the sash. When in this position the screws are at the proper depth to engage the casing of the sash pull in a manner which will be later described.

The sash pull includes the casing il which encloses the projecting ends of the screws II. The casing Il includes a top plate I9 and a parallel bottom plate 2G. The plates I9 and 20 are provided with arcuate outer edges which are connected by the connecting edge 2 I. The top plate I9 merges into an outwardly extending flange 22 which in turn is bent to form the marginal ange 3 extending substantially parallel to the upper plate IS. The lower plate 20 likewise merges into an outwardly extending flange 24 terminating in a marginal ange 25. The outwardly extending flanges 22 and 24 and the marginal flanges 23 and 25 blend integrally into the connecting edge 2i, the effect being to widen the sash pull at the base thereof. Obviously the top and bottom plates I9 and 2B could extend into contact with the inner surface of the sash B if desired and the flange structure defined could be eliminated with the consequent narrowing of the base of the pull.

In the lower plate or surface 2B I provide a pair of elongated indentations 25 and 21 which terminate in larger circulator indentations 2S and 3i! respectively. These various indentations are for holding the sash pull in proper position relative to the screws II. The larger indentations 29 and 3S each engage on one side of one of the screws II holding the casing Il from movement transversely of the sash. The indentation 29 engages the side of the left hand screw head I5, thus preventing the casing I'I from moving to the left as viewed in Figures 1, 2, and 3 of the drawings. The indentation 30 engages on the opposite side of the head I5 of the right hand screw II, thus preventing the casing Il' from moving to the right as viewed in Figures l, 2, and 3. The manner in which the indentations Z9 and 39 engage against the screw heads I5 is best illustrated in Figure 3 of the drawings.

The smaller elongated indentations 26 and 2'! engage beneath the shoulder 3I formed between the shank I@ and the head I5 as best illustrated in Figure 4 of the drawings. These indentations 26 and 2l' hold the casing I'I from easily becoming disengaged from the projecting portions of the screws I I. These elongated indentations, however, are of such a size as to permit the lower wall 2G of the casing I7 to bow downwardly somewhat during insertion or removal of the casing from the projecting portions of the screws.

In the lower flange 25 I provide a pair of spaced apertures 32 into which the pointed end of a screw driver or other such instrument may be inserted if it is desired to remove the housing II from the screws II. By prying the housing I'I away from the sash B the housing walls will eX sufciently to permit the screw heads I5 to pass the indentations 25 and 2?.

The manner in which the sash pull may be attached or removed is believed obvious from the foregoing description. The screws II are inserted in the sash in proper spaced relation and at the proper depth in the manner previously described. The housingr is then attached by inserting the projecting ends of the screws into the open end of the housing, the indentations 2S and 36 providing a guide for properly positioning the housing relative to the screw heads. The heads I5 are forced past the indentations 25 and 27, the walls of the housing spreading sufficiently to allow the screw heads to enter. As the open end of the housing reaches the surface of the sash, the indentations 25 and El pass the enlarged screw heads I5, engaging beneath the shoulders 3|.

The sash is thus held in place and will resist f extreme force in the act of raising or lowering the sash. If it is desired to paint the sash the housing I'I may be removed by merely inserting a screw driver first in one slot 32 and then the other, prying the housing away from the inner surface of the sash. This prying force again spreads the uppel` and lower surface plates I9 and 20 apart sufficiently to allow the indentations 26 and 27 to pass the screw heads. The housing I? is usually formed of sheet metal and in preferred form comprises a single drawn stamping formed of a at sheet of stock.

In Figure 5 of the drawings I disclose a modied form of sash pull C. This sash pull C may also be attached to the sash B in much the same mannel` previously described. This sash pull comprises a screw 33 having a threaded end 3d in a circumferential flange 35 adjoining the threaded end, a reduced diameter' shank portion 35 and a head 3l, preferably having a screw driver slot 39 therein. The screws 33 differ from the screws II only in the flange 35 which encircles the shank 36 and limits the insertion of the screw into the sash.

The housing Llil is identical with the housing I7 previously described with the exception of the fact that slots or recesses 32 are provided adjacent the screws 33 rathel` than spaced therefrom as in the previously disclosed construction. As a result the end of a screw driver D may, if desired, be inserted through each slot 4I and may rest upon the flange 35 and thus may pry against this flange rather than against the inner surface of the sash. This construction has the advantage that it is easier to determine when the screw is inserted to the proper depth. The structure also has the advantage of providing a solid base against which a tool may engage in prying the housing out of place. The structure shown in Figure 5 has the disadvantage of somewhat higher cost. The depth to which a prying tool may be inserted is also limited in this structure.

In accordance with the patent statutes, I have described the principles of construction and operation of my sash lift, and while I have endeavored to set forth the best embodiments thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.

I claim:
