SASH-GUIDE.

Specification of Letters latent.

Patented July 28,1914.

Application filed June 12, 1913. Serial No. 773,162.

T0 all whom t may concern:

Be it known that I, Eton It. LEONARD, a citizen of the United States, residing at llfoodcliii", county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Sash-Guides, of

which the following is a specification.

My invention is intended for use in. connection with window sashes which are ypiv-l oted` in such a way that they lmay be swung out of a perpendicular position in their frames and be held at an angle thereto, for the purposes of ventilation, cleaning or otherwise, and it consists in means for hold#l ing the sashes at various angles and for al-y lowing them to be raised or lowered in infk clined positions as is hereinafter pointed out.

In the drawings Figure 1 is a vertical sec-I tional view of a window frame and sashes equipped with my improved device; Fig. 2 is a similar view showing the sashes inclined way from the perpendicular; Fig. 3 is a top view on an enlarged scale taken on the line 1, 1 of Fig. 1; Fig. 4 is a side View partly in sect-ion of the extensible guide and holder; Fig. 5 is a similar view showing` the guide rod extended; and lFig. 6 is a perspective view of the guides detachable cap.

Similar reference numerals designate similar parts in all the ligures.

The sash frame 2 is provided with front sash-stops, but with no back stops, so that the tops of the sashes may be swung inward when desired. 'The sashes are counterbalanced, being carried by chains 3 passing over suitable rollers 4 and attached to the sashes near their bottoms as by pins 5 extending into the grooves in the side of the frame. The upper sash is provided with a retractable bolt or bolts normally projecting into the frame groove 6 to hold the sash in its position in the frame. These elements of construction are not part of my present invention being the subject matter of a previous application for a patent by me; and they are only referred to herein for the purpose of clearly explaining the operation of my present improvements.

The body of my improved guide is formed of a tube-like member 7 which is connected by a suitable pivot arm as 8 with a sliding head 9 having an undercut extension 10 sliding within a slit tube 11 riveted or otherwise firmly secured within the groove 12 in the sash frame. I have shown the pivot arm 8 as provided with an annular groove 13 into which projects a set screw 14 threaded through the neck of the sliding head, and the pivot arm 8 also carries a guide roller 1 5 loosely mounted thereupon.

Within the guide-body 7 is mounted a rod 16 provided with a head 17, the opposite end of the rod projecting through a cap 18, provided with a slotted sleeve 19, and threaded `into the end of the guide-body 7. The outer end of the rod 16, is pivoted in the split pin 20, which is attached to the top of the lower sash, as by being threaded into angle iron 21 secured in the interior of the sash frame.

Upon the guide-body 7 I provide means for engaging with and holding the rod 16 at,k

any point to which it may be adjusted. I have shown this means as consisting of an eccentric lever 22 pivoted between lugs 23 on the guide-body in such a relation thereto that its eccentric cam 24, when projected, will extend through the slot Q5 in the sleeve 19 and will clamp against the rod 16, but when the yeccentric cam is retracted it will be raised entirely out of the slot 9,5, thereby not only releasing the rod 16 but also permitting the cap 18 to be unscrewed.

The operation of my device is as follows':-If the sashes are closed, as shown in Fig. 1, and it is desired to open the top of the lower sash, it is irst raised slight-ly to disengage its interlocking rail from the rail of the top sash, and its top is then drawn inward, the head 9 sliding upward in the sash groove, until the guide-body 7 has swung under and past it, and then sliding down again to a pointat which it will sustain the drag of the lower sash. Either before or after the sash has been thus swung in, the cam lever 22 may be swung out and the guide-body 7 slid along the rod 16 so as to give a greater or less freedom of movement to the top of the sash as may be desired, the cam lever being again clamped down upon the rod when the adjust-ment has been made. In case it is desired to open the sash still farther, as for cleaning and the like, the cam lever is swung down, releasing the rod 16 and the sleeve 19, after which the cap 18 is unscrewed and the rod 16 is entirely withdrawn from the guide-body 7, the head 17 preventing the cap 18 from sliding o the rod 16 so that it might be lost or mislaid. The disposition of the cam 24 in the slot 25 serves, normally, to prevent the unscrewing of the cap 18 by careless or inquisitive persons; while the retractability of the cam still allows the parts to be separated by those who have been specially instructed in the operation of the mechanism. To open the upper sash inward, it is lowered slightly and its top guide bolts are withdrawn from the frame grooves 6, after which the top of the sash may he drawn in until its side rail rests upon the guide-roller 15 as shown in Fig. 2. And the sashes when in this posit-ion may be raised or lowered, the upper sash sliding past the roller different angles to the vertical correspond-v ing with the various relative positions of the pivots 5 and the roller l5.

It will be obvious that the upper and the lower sashes may be opened to varying eX# tents and at different angles as may be found desirable. Thus, if the lower sash is not opened inward, the extent to which the top of the upper sash shall be swung in may be regulated by sliding the guide-body 7 a greater or less distance along the rod 16 and clamping it at the preferred position, so as to raise or lower the guide-roller 15, and correspondingly limit the inward movement of the top sash. And Various other modifications of operation 'will be apparent to l5, and adjusting itself at those accustomed to regulating windows of this character. And l wish it to be understood that I have described and illustrated a preferred but not an exclusive form of my device; for it is manifest that the details of construction may be varied without departing from the spirit of my invention.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is l. The combination, with a frame of a pair of counterbalanced, pivoted sashes, an extensible guide slidably connected at one end to said frame and pivotally connected at the other end to the lower sash, and carrying an antifriction upper-sash guide element.

2. The combination, with a frame of a pair of counterbalanced, pivoted sashes, a guide slidably connected at one end to said frame and pivotally connected at the other end to the lower sash, and carrying an antifriction upper-sash guide element.
