Application filed April 7,1893. Serial No. 469,423. (No model.)

To aZZ whom it may concern:

Be it known that 1, DAVID P. HOPKINS, a

. resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Window Frames and Sashes; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to window frames and sashes, and has special reference to the particular kind of window frames in which the sash is pivoted so as to rotate inthe frame in orderto open or close the window as desired. Heretofore in the use of these window frames and sashes, the great difficulty was that the sash was generally smaller than the frame space, and had a follower resting loosely on its top which worked through the frame and closed the opening between the frame and sash causing a non weather-tight joint which allowed dust, rain and wind to enter the apartment. Another difficulty was that when the sash was raised above the sill by means of a raiser or clamp at its bottom, in order to turn or rotate the same, the operator was required to exercise great strength on account of the window and follower being heavy,

these particular devices being generally used.

only on large windows, which were cumbersome and difficult to handle in cleaning the outside surface of the glass.

The object of my invention is to overcome these difficulties, and to provide a window frame and sash, which, when the sash is closed, forms a practically weather-tight joint, excluding all liability of rain, dirt and wind entering the apartment. 7

Another object of my invention is to provide a window frame and sash in which the sash is practically the same size as the frame space, and which can be turned without having to raise the sash, so that the window can be opened when desired and permit the cleaning out of the outside surface of the window or the entrance of air into the apartment, as desired.

To these ends my invention consists, broadly, in a window frame having a follower moving in guides therein, a sash within said frame, said sash being of the same size as the frame space and being pivoted at its top to the follower and at its bottom to the frame.

It further consists in a window frame having a sash therein pivoted at its top and bottom, said sash being of the same size as the frame space and adapted to be clamped to the sill of the window frame.

It also consists in certain other details of construction and combination of parts,-all of which will be more fullyhereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which Figure l is a side view, partly in section, of a window frame and sash showing my invention applied thereto. Fig. 2 is a like view showing the sash rotated or turned in the window frame. Fig. 3 is a vertical central section through the window frame and sash. Fig. 4 is an enlarged sectional View showing the clamp for engaging with the sill and sash. Figs. 5, 6 and 7 are detail sectional views of the window frame and sash. Fig. 8 is a perspective view of the clamp case. Fig. 9 is a perspective view of the lever for operating the clamp. Figs. l0, 11, 12 audl3 are detail perspective views of different parts of the clamp. Fig. 14: is a view showing another form of my invention; and Fig. 15 is a detail section on the line 15-15, Fig. l4.

Like letters of reference herein indicate like parts in each of the figures of the drawings.

My improved window frame and sash are illustrated in their preferredformin Fig. 1,the window frame being shown at a, and having the vertical portions a a and the sill a On the left side in front of the window is the vertical weather strip a and on the opposite side back of the window is another weather strip a. Moving in guides a in the window frame a is the follower b which rests upon the top 0' of the sash c and acts to close the opening made between the sash c and the window frame. The lower face b of the follower 12 engages with the top 0 of the sash c by means of a rabbet or tongueb' which fits within a seat or groove 0 formed in' the sash c and acts to form a tight joint.

The sashc fits neatly within the window frame and is formed of the same size as the frame space within the window frame a, being pivoted at its top to the follower b and at its bottom to the sill a in the ma-nner hereinafter described. Secured to the bottom 6 of the sash c in any suitable manner is the clamp d, which acts to clamp the sash 0 down onto the sill er when the window is closed, and to raise the follower b when the said clamp d is freed from the sill a so enabling the sash c to be turned. The clamp d is formedof the case (1', which is attached to the bottom 0 of the sash c by the screws (1 and has formed in it the seat of for the reception of the bearing piece 6, this bearing piece e having the vertical guide arms e e which move on each side of the guide d in the seat 61 of the clamp, the guide 01 fitting within an opening 6 between the vertical guide arms e e of the bearing piece. Projecting from said bearing'piece e is the horizontal portion e which fits within the bottom 0 of the sash cand carries the pivot pin c, said pin ef" fitting within the plate fattached to the sill a of the window frame and forming the lower pivot of the swinging sash c. Fitting up against the case 01 is the revolving plate g, which has on its interior face g the cam or eccentric h, said cam or eccentric h having the stop h which engages with a lug or pin 2' on the vertical guide arm 6 of the bearing piece e, and the face of said cam or eccentric h bearing on the projecting face j on the bearing piece e. In order to operate said clamp d, a lever la is provided, which has the journal pin extending out eccentrically from the inner face thereof, and passing through the revolving plate 9 enters an opening is in the case (1 and is journaled and riveted thereto, the said lever 70 being provided with a handle 70 for convenience in operating. The journal pin 70 is mounted eccentrically on the lever 70 and has a square portion 10 thereon which fits Within a square seat 9 in the revolving plate g, and the said lever k is further provided'with a lug Zwhich fits within a seat m in the revolving plate 9 which assists in revolving the plate 9 when the lever is is turned. Extending out from the top of the case 01' of the clamp 01 is the guide 01 which has a guideway n therein, through which the lifting bar 0 passes, the said lifting bar 0 being provided with a guide 0 on its vertical portion 0 which fits within the guide-way n of the guide n. At the lower end of the vertical portion 0 of the lifting bar 0 is a lug 0 which fits and travels within a cam or eccentric seat 10 on the exterior face 9 of the revolving plate gand operated by the lever is which has its journal pins is mounted off the center so as not to interfere and enable the cam or eccentric seat p to perform its work in engaging with the lug 0 on the lifting bar 0. The lifting bar 0 has the horizontal portion 0 projecting out therefrom provided with a threaded opening 0 within which the rod g by its threaded end q engages. The rod (1 extends up in front of the sash c and passes through an opening 1 in the top a of the sash c. On the lower face 6 of the follower b there is provided the plate .9 which fits within the seat b in the follower b, said plate 8 having the extension 5' formed thereon which extends down into the enlarged portion 1" of the opening r in the top a of the sash c and forms the upper pivot of the sash. The rod q engages by the threaded upper end g with the threaded slot 3 in the extension 8 of, the plate s and acts to raise the follower b when desired. In the closed position of the.

sash c the extension or pivot s of the plate 3 in the follower b rests against the head r in the top 0 of the sash.

For the purpose of excluding all liability of wind, rain or dust entering the apartment when the window is closed, there is provided on the lower face 0 of the sash c a rubber or like flexible strip 25, said flexible strip 15 entering a seat t in the bottom a of the sash, and extending down a short distance so as to contact with the sill a of the window frame, as is fully shown in Fig. 7.

The operation of my improved window frame and sash will now be described. As is shown in Fig. 1, the sash is in its closed position, with its lower face 19 clamped down against the sill a of the window frame, and the lever is being turned to the right side of the clamp d. To assume this position of the lever 70 allows the turning of the revolving plate g which causes the cam or eccentric h to travel over the projecting face j on the bearing piece e until the cam or eccentric h reaches the point nearest the center of the journal pin 70, so lowering the bearing piece 6 and the sash slightly and clamping the sash a down onto the sill a of the window frame a which compresses the flexible strip 23 against the sill 0t and forms a weather-tight joint at the bottom of the window. At the same time as the revolving plateg is turned to the right, the cam or eccentric seat 19 on the revolving plate 9 is turned until the lug 0 on the lifting bar 0 reaches the.point nearest the center of the journal pin it on the lever is, so lowering said lifting bar 0 and the rod q allowing the extension s' on the plate 8 to seat itself in the opening 'r and pull the follower 19 down onto the top 0 of the sash c, the rabbet b fitting within the groove 0 in the sash c and forming a weather-tight joint at the top of the window. In order to unclamp the sash from the sill a of the window frame a so as to permit the swinging of the sash c in the frame a, the operator grasps the handle 7.2 of the lever k and turns it to the left whichcauses the turning of the revolving plate 9, the cam or eccentric h traveling around on theprojection j of the bearing piece 6 until the cam or eccentric h reaches the point remotest from the center of the journal pin it of the lever 70, so forcing down the bearing piece 6 and raising the sash 0 upon its pivot pin 6 in the sill a of the window frame. At the same time the revolving plate 9 is turned to the right, the lug 0 on the lifting bar 0 is travel ing in the cam or eccentric seat and when the ISO revolving plate g is turned sufficiently so that the cam or eccentric seat p reaches a point remotest from the journal pin it on the lever 70, thelug will reach its highest point and means of the rod q being connected to the extension or pivot .9 attached to the follower b as is fully shown in Fig. 5. After the turning of the lever is to the left as above described, the sash is ready for swinging or rotating, the saidsash c turning upon the pivot "pinve of the bearing piece e attached to the silla of the'window frame, and the follower b being separated from the top 0' of the sash allows the sash c to swing upon the extension or pivot s which is still resting in the opening 7' at the top of the sash, thus enabling the operator to swing or rotate the sash 0 upon the pivot pin 6 at the bottom and the I extension or pivot s at the top of the window frame.

In Fig. 14 I have shown another form of device in which the rod q can be dispensed with, the follower b sliding loosely in guides in the window frame, and having rollers or wheels u mounted therein which fit within the rounded seat to in the sash formed for the rabbet or projection 10 in the follower. The sash is pivoted at the top by means of the bolt '12 screwing into the sash through an opening 12' in the follower and having a head 11 to limit the movement of the follower when raised.'

After the clamp 01 has been released by the turning of the lever is to the left, the sash can be turned upon the pivot pin 6 at the bottom of the window frame and the bolt 1; in the follower, the rollers or wheels to turning in the seat to by friction exerted in opening the sash which frees the follower and forces it up and freeing the rabbet or projection 21, from engagement with the seat 10 in the sash. After the sash has been swung on its pivots, it can be lockedin any position by turning the lever It back to its closed positionwhich clamps the sash 0 down onto the window frame.

It will be seen that my improved window frame and sash are easily operated and can be clamped down on the window sill tightly, which makesa weather-tight joint, all liability of wind, dust or rain entering the apartment being overcome. The sash fits neatly within the frame space of the window frame, and the follower fitting in the top of the sash by a tongue and groove joint prevents the entrance of air, wind, rain or dust at that point. The clamp is simple in construction and can be operated without any great strength, it not requiring the lifting of the window sash from a seat in the window sill, which is common to this class of windows. It does not mar the appearance of the sash, sill or window frame and the parts are all strong and not liable to getoutof order.

What I claim as my invention, and desire to secure by Letters Patent, is
