Application filed February 26, 1917. Serial No. 150,918.

To all whom it may concern:

Be it known that I, HARVEY E. 'Hnnsn, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Mechanism for Operating Swinging Sashes, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to operating mechanism to be used in connection with sashes or transoms, especially where such sashes are wide, or are arranged in horizontal series.

Under these circumstances, it is desirable that the force tending to swing the sash or sashes, be applied at regular intervals in order to avoid torsional strain along the pivoting axis of the sash. To this end, my invention includes horizontal sliding bars with connections at suitable intervals, where by motion of reciprocation of the bar is translated into motion imparting to the sash the requisite swinging movement.

In the accompanying drawings, Figure l, is an elevational View showing parts of one or more swinging sashes having my operat ing mechanism applied thereto.

Fig. 11, is a perspective view showing a part of a sash and the operating mechanism.

Fig. III. is a sectional view along the line 111, 111 of Fig. 1.

A framework 1,1, 1, incloses a long sash or series of sashes, involving horizontal members 2, and vertical members 3. These sashes are pivoted along a horizontal axis by means of the pivots 4, mounted on lugs 5, set upon a horizontal member 6, which is in stationary relation to the sash frame.

The members 7, 7 are in like stationary relation to the sash frame and carry slide bearings 8, 8, 8. 8, within which are mounted slide rods 9, and 10. In order to secure reciprocal motion of these two slide rods, their extremities are connected by chains 11, 11, passing around pulleys 12, 12. At suitable intervals, there is setupon the slide rod 9, a collar 13, to which is attached the chain 14-, which passes around the guide pulley 15, and thence around the larger pulley 16, after which it returns around a second guide pulley 17, and finds attachment upon a collar 18, set upon the slide rod 10. This chain is of suitable length and tension so that as the rods 9, and 10, reciprocate, the pulley 16, which is mounted upon an axis parallel to that upon which the sash swings, has impart ed to it, a motion of rotation. The means employed for suitably mounting the pulleys 15, 1.6 and 17, will be suflicientlyi understood from the drawings without detailed description and may vary according to circumstances.

The pulley 16, has set upon it an arm 20, to the swinging end of which is pivoted a link" 21, the far extremity of which is in turn pivoted to the sash at 22. Similar pul leys 16, with chain and guide pulleys and with an arm 20, and link 21, are set at convenient intervals along the entire length of the reciprocating rods 9, and 10, and at each such point, by the elements which have been described alternating reciprocation of the rods is translated into a thrust by the links 21, imparting to the sash or sashes to which they are pivoted an even swinging motion upon the horizontal axis of said sash or sashes. Y

In order to communicate proper reciprocal 1 swinging motion. In such case it may be convenient to attach to the sash a longitudinal member 10, to serve as acommon point of attachment for the pivoted ends of these links. Where a series of swinging sashes are arranged upon a common horizontal axis, each one may have one or more points of attachment depending upon the length of each sash and the number of attachments necessary to impart to it an even swinging mo tion without torsional strain.

Having thus described my claim: I

1. The mechanism for imparting axial rotation to a swingin sash, consisting of two horizontal slide rods; means for obtaining alternate reciprocation thereof; a pulley set on an axis parallel to that on which the sash swings; a chain passing around the pulley with its extremities fast to the rods, wherer by the reciprocation of the rods rotates said pulley; and an arm and link by which r0- tation of the pulley imparts swinging motion to the sash.

2. Mechanism for imparting axial rotation to parallel swinging sashes including in combination slide rods parallel to the axis on which the sashes swing; means for obtaining alternate reciprocation of said rods; brackets rigidly mounted in proximity to said rods; a pulley mounted in each of said brackets in position between said rods; a pair of guide pulleys mounted in each bracket at right angles to the pulley; a chain passing around the pulley and guide pulleys in each bracket with its extremities fast to i the rods whereby the reciprocation of the rods rotates said pulley; and connections whereby the rotation of each pulley imparts swinging motion to a sash.

3. The mechanism for imparting axial rotation to parallel swinging sashes consisting of slide rods, parallel to the axis on which the sashes swing; means for obtaining alternate reciprocation of said rods; pulleys mounted rigidly and independently of said slide rods, set on axes parallel to those on which the sashes swing; flexible means attached to the slide rods and extending over the pulleys whereby reciprocation of the slide rods imparts a simultaneous and equal rotation to the pulleys without lateral strain on the rods; and connections whereby rotation of each pulley imparts swinging motion to a sash.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania, this 12th day of February, 1917.
