y 1948- c; F. RECKLITIS ADJUSTABLE SASH HOLDER Filed April 4, 1947 Patented May 25, 1948 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to adjustable sash holders intended to be employed in frictionally holding dwelling windows in any position to which moved.

The problem of replacing broken sash cords is a common and troublesome one involving considerable expense and often marring of the window construction. The sash holder of the present invention may be used as a substitute for sash balancing means which have become broken, or it may be installed in new windows with an appreciable saving in construction costs.

It is the general object of this invention to provide a simple and efficient form of friction engaging sash holder which may be conveniently adjusted at any time to provide the required amount of resistance to window-movement.

In particular, it is an object of this invention to provide a sash holder having a spring pressed member for frictionally engaging the window frame adjacent the edges of the sash which may be very easily and readil installed. A related object is attained by the provision of an adjustable sash holder comprising a minimum of parts.

It is a further object of this invention to p1'0 vide a sash holder having an unsymmetrical configuration which will afford a relatively larger amount of clearance with respect to the glass of the sash and thereby minimize the possibility of breakage in installation or adjustment.

These and other objects of the invention will be apparent from a consideration of the following detailed description of a preferred embodiment of the invention taken with the accompanying drawings in which:

Fig. 1 is a front el evation of a conventional window structure partially sectioned to show the application of the sash holder of this invention;

Fig. 2 is an enlarged fragmentary section taken on line II-II of Fig. 1 showing the sash holder in operative position; and

Fig. 3 is an exploded perspective view showing further details of the sash holder.

With reference to Figs. 1 and 2, a conventional window structure I!) is shown comprising a window frame [2, an upper sash l4, and a lower sash I6. The lower sash l6 includes stiles l8 and maintained between a parting strip 22 and an inside stop strip 24' in the conventional manner indicated in Fig. 2:.

Preferably, the upper and lower sashes I4 and IE will each be provided with two sash holders 26 mounted in opposed relation in opposite stiles. The construction of the sash holder is such that two holders are often sufiicient for a single sash, although additional ones may be used where the sash is unusually large or heavy. If only a single sash holder is employed, there may be a tendency to force the sash to one side of the frame and produce unwanted friction between the sash and the adjacent side of the frame.

The details of construction and the arrangement of the parts of the sash holder 26 are best illustrated in Fig. 3. The sash holder 26 is preferably made of a non-corroding metal and formed to shape in any conventional manner. Frictional engagement with the window frame i2 is attained by a rectangular runner block 28 received in a chambered housing member 30 which is fitted into the stile I8 in the manner shown best in Fig. 2, and urged into engagement by a spring 32 having an adjusting screw 34.

The runner block 28 is elongated to provide adequate bearing surface with the window frame and to maintain the window sashes in parallel relation thereto. By forming the block 28 with opposite rounded ends 35, 36, gouging of the window frame is prevented. It will be noted that the runner block 28 includes a plunger portion 38 provided with an end 42 of reduced diameter forming an abutment shoulder 46 for engagement with the adjacent end of the spring 32.

The chambered housing member 36 is of integral construction formed to provide a rectangular slot 45, a trough portion 46 forming a continuation of the opposite sides of the slot 45, and a tubular. portion 48. The free end of the tubular portion 48 is provided with internal threads 50 for threaded engagement with the adjusting screw 34.

It is to be particularly noted that the slot 45, which extends lengthwise of the elongated face plate portion 43, is offset with respect to the longitudinal axis of that portion. This unsymmetrical arrangement of the slot as and the trough portion 46 which forms an in line continuation thereof is an important feature of the invention. The tubular portion 48, which is preferably circular in cross-section, opens into the bottom of the trough portion 4'6, is disposed centrally thereof, and has an internal diameter approximately that of the width of said trough portion.

The complemental engagement .of the face plate 43 and trough portions of the housing 30 with the rectangular runner block 28 constrain the latter from turning and together with the close fitting plunger 38 guide its outward and inward reciprocating movement.

In the installation of one of the sash holders 26, the stile It as shown in Fig. 2 is mortised to provide a recess 52 for the face plate ,43 and trough portions and bored to provide an opening accessible at the inner edge of the stile for receiving the tubular portion 48 and permitting adjustment of the screw 34. The housing 3% will extend lengthwise of the stile in the manner shown in.Fig 1 and will have its face plate portion 43 turned so that the ofiset of the slot 55 will be in the direction of the inside of the sash IB, that is toward the stop strip 25. In this manner the necessary width of the face plate cs is attained while at the same time, the bored opening and the adjusting screw 34' are given added clearance with'respect to the plane of a window glass 56, for example. 7 r
