WINDOW-OPENER.
Specification of Letters Patent.
Patented Oct. 15, 1907.
To all whom it may concern:
Be it known that we, .ToHN Howaim CARTLAND, a subject of the King of Great Britain, residing at the Priory, Vicarage Road, Kings Heath, Birmingham, England, and lessen LILLY, a subject of the King of Great Britain, residing at 135 \Yavcrley road, Small Heath, Birmingham, England, have invented certain new and useful Improvements in Mechanism for Opening and Ulosing Swinging Windows or the Like Casements. of which the following is a specification.
This invention relates to improvements in mechanism lor opening and closing swinging windows, ventilators, or the like, and its object is to provide improved means whereby the arm or rod employed in such mechanism shall automatically assume a position as near as possible to the casement when the latter is closed; also improved construction of pulley; also improved means for carrying said pulley, These improvements are effected by the mechanism herein illustrated upon the drawings, upon which are figures and reference numhers, similar numbers referring throughout the several views to the same part, and in which 2 Figure 1 shows a side view of our invention as applied to a screw rod gearing, in which the easement is seen to be partly open. Fig 2 shows the same arrangement in its closed position. Fig. 3 is a sectional plan view on line A-B (Fig. 1) showing the construction of the pulley and the arrangement of mounting same. Figs. 4, 5, and 6, show our invention as applied to the side of a hinged casement. Fig. 7 shows a detail plan view of the bracket for carrying the pulley when so applied to the side of the easement.
-9 represents the frame to which the lower part of the moving casement 10 is hinged, and in Figs. 1, 2,
and 3 our invention is shown as it would be applied to the center or therea-bout of the easement v10, while as before intimated, Figs. 4 to 7 inclusive show its application to the side of such a casement.
11 is the arm or rod which is formed at one end with a short cranked part 12, which is pivoted at 13 to any suitable bracket 14, said bracket being secured to the frame 9. The 'main part of the rod 11 is formed with a screw thread to accommodate the gearing as hereinafter explained, but may be formed with rack teeth to accommodate other forms of gearing if required.
15 is a pulley having the circumferential groove 16 to accommodate the manipulating cord 17, and said pulley being internally screw threaded to suit the rod 11.
18 is the swivel box having a central hole in which the boss 19 of the pulley 15 freely revolves, that is, said hole forms a bearing for the boss 19. At the outside of said boss the said pulley is reduced somewhat in diameter at 20 to receive a washer 21, the extreme part of the boss being then turned over at 22 so as to fix the pulley 15 in the box 18, but free to revolve therein.
23 is the bracket for carrying thc swivel box 18, havin g arms 24 upon which are formed pivots or trunnions 25, with bearings 26 formed upon the box 18. The arms 24 of the bracket are sprung open so as to permit the box 18 passing between trunnions 25, when the arms 24 are then closed, so that the said trunnions permanently occupy the bearings 26 ready for use.
Referring now to Figs. 4 to 7 it Will be seen that in order to adapt our invention for use at the side of the casement, we modify the bracket which carries the swivel box, and which is attached to the moving casement as shown at 23 and in agreement therewith We provide upon the one side of the box 18 along pivotal arm 25 which is revolubly secured in the said bracket 23. We im'ther provide upon the said box 18 guide pulleys 27 for the cord 17. Beyond these minor modifications in detail it will be seen that the principle and action is precisely as before described in reierence to Figs. 1, 2, and 3. I
It will be seen that the short crank 12 01". the arm 11 is so arranged that the centers of movement at 18 and at 25 are horizontally level with each other (or thereabout) when the mechanism is in the closed position, by reason of which not only does it enable us to keep the two said centers of movement comparatively close to each other, so that as little projection occurs as possible from the easement, but it also effectually prevents any backlash or movement of the easement wh en closed. By these means when the easement is closed the long part of the arm 11 lies parallel to thesaid casement, but as the cord or other medium is operated to rotate the pulley the arm is first raised towards the outstanding position with but a slight movement of the easement, and as it proceeds, so the casement opens, the position of the said arm continuing to assume the position convenient for the continuation of such opening movement. Upon the closing of the casement, as it nears such a position the arm or rod is automatically moved into the before named down hanging position lying parallel to the said casement.
Although we have described and illustrated our in- 'vention as applied to easements hinged top or bottom, it will be readily seen that it may be also equally applied to casements hinged at one side.
\Ve are aware that in mechanism of this kind it has already been proposed that the arms shall be made to more or less fall down somewhat out of the way by the bending or curving of such arms, but in such cases the said arm has been provided with a pivot joint which has stood forward or upward of the gearingmechanism when the window has been closed, and therefore much more in the way than in the case of our invention.
What we claim as our invention. and desire to secure by Letters Patent is:'
1. Mechanism of the class described, involving a feed screw member having a crank part fixed thereto and pivotally connected to a window frame, a pulley rotatable on said feed screw and movable throughout the longitudinal extent thereof, means for pivotally supporting the pulley and fixed to a window sash, and means for actuating the pulley for moving the same longitudinally on the feed screw member.
2. Mechanism of the class described, involving a fixed bracket carried by a window frame, a crank part connected with the bracket, a screw threaded rod fixed to said crank part, a pulley rotatable on the rod and movable throughout the longitudinal extent of the same, means for rotatably supporting the pulley, a bracket for the said means fixed to a window sash, and means for actuating the pulley.
3. In a window frame and sash, a bracket fixed to said frame, an arm pivotally 'connected with said bracket, 3. rod carried by the arm, a pulley longitudinally movable on the rod, a bracket fixed t0 the sash, a box for rotatably supporting the pulley and swiveled to the latter bracket, and flexible means associated with the pulley for rotating the same on the rod.
In testimony whereof we have hereunto set our hands in the presence of two subscribing Witnesses JOHN HOWARD CARTLAND. JOSEPH LILLY.
