A TTORNE V8 UNITED STATES PA ENT OFFICE.
WILLIAM H. LOGAN, OF BANDON, OREGON.
To all whom it may concern Be it known that I, lVnmLxM H. Looax, a citizen of the United States, and a resident of Bandon, in the county of Coos and State of Oregon, have invented certain new and useful Improvements in Screens, of which the following is a specification.
My invention is an improvement in screens, and the invention has for itsobject to provide a screen especially adapted for covering'windows and other openings, to prevent the entrance of insects and the like, wherein the screens are supported on spring mounted rollers arranged in suitable openings in the window casing, and are connected to the sashes, to be moved into and out of position over the opening when the sashes are moved in the casing.
In the drawing, Figure 1 is a partial perspective View of a window provided with the improved screen; Fig. 2 is an end view of one of the screen supporting rollers, Fig. fl is a partial side view, with parts in section, of the roller, and Figfl is a partial side view, with parts in section, at the opposite end from Fig. 3.
In Fig. 1 the improvement is shown in connection with a window casing consisting of the top member 1, the sill 2, and the side members 3, but one of which is shown, and sashes 4: and 5 are mounted to slide in grooves 6 and 7, respectively, of the casing, the said grooves being in the side members thereof.
Rollers, to be described, are arranged at the top and bottom of the easement, and adjacent to the sashes 4 and 5 when the sashes are in normal position. That roller adjacent to the sash 4 is arranged above the sash Within a groove 8 extending longitudinally of the'upper cross member 1 of the casement, and a metal shield 9 partially covers the opening of the groove. The shield is spaced apart from the. parting strip 10 which separates the groove 8 from a groove 11 in rear of the same and extending parallel therewith, and at the free edge the shield is provided with a depending flange. 12.
The roller adjacent to the sash 5 is arranged below the sash, on a rabbet 13 in rear of the rabbet 14 upon which the sash rests when in closed position. A shield of angle materialis provided for this roller. The said shield consists of a vertical portion 15 which is secured to the inner framing member 16 of the easement and an approxi- Specification of Letters Patent.

the adjacent roller and secured thereto,
while the'other end is secured to the adjacent sash. The upper cross memberof the sash 4, and the lower cross member of the sash 5 are rabbeted on their rear faces and at their lower edges, as indicated at 20, and
the adjacent ends of the screens are received 4 in these rabbets, and are secured to the sashes by nails 91, screws or the like.
The rollers above mentioned are spring supported and are journaled for rotation, in such manner that when the sashes are moved away from the rollers the screens will be withdrawn from the rollers into position over the opening left by the movement of the sash, and when the sashes are closed, the slack in the screen will be taken-up by the rotation of the roller under the influence of the spring.
Each roller has one end recessed axially as indicated at 23 to receive a coiled spring 25, and one end of the spring is connected to the roller in any desired manner. That end of the roller adjacent to the recess 23 is provided with a longitudinally extenl ing inwardly offset flange 24, which is received within an annular groove or recess 26 in the inner end of a cap or head 27 which supports a spindle or trunnion 28 for the roller.
The spindle ortrunnion is journaled in a central opening oflthe cap, and the outer end of the spring 25 is secured to the inner end of the spindle' The'outer end of the spindle is flattened, as shown ;at 28, to en-- gage a similar bearing bracket secured to the casement, and it will be evident that when the roller is rotated by the unwinding of the screen, the spindle being held by the bearing, the spring 25 will be placed under tension.
A ratchet wheel 29' is secured to the spindle at the junction of the flattenedpor tion with the body of the spindle, and pawls 30 are pivoted to the cap at the'ratchet roller is provided with the mounting shown.
in Figs. 2 and 3, so arranged that when the sash is moved in a direction to withdraw the screen from the roller, the spring will be placed under tension in order to return the roller to original position when the pressure on the spring is relaxed.
In operation, when the sash 4 is lowered or the sash 5 is raised, the screen connected with the sash will be withdrawn from its roller, passing out alongside the free edge of the shield. When the sash is returned to normal position, the spring roller will draw up the screen, rewinding it on the adjacent roller. The windows are thus always closed to insects or the like, and when the windows are in closed position the screens are concealed from view, so that there is no change in the outward appearance of the window. The screens are also protected fromthe weather when not in use, and they are always in place, so that there is no danger of losing the screen.
It'will be noted from an inspection of Figs. 2 to 4 inclusive, that preferably a casing is provided for receiving the screen. This casing is arranged in the recess 8, and as shown, the casing consists of a base or body 32, and sides 33 and 34 extending from the Side edges of the body in parallel relation, and ends 35 and 36. The casing is of nietal of suitable weight, and may be formed in any suitable manner.
Strips 37 are secured to the casing near its end and to the sides 34, and said strips extend above the body 32 and have openings for receiving screws 38, to secure the casing in place. Each of the ends 35 and 36 is provided with a bearing 39 and 40, respecti ely, for receiving the adjacent trunnion (if the sash roller. The end 35 is fixed, and carries a bearing 39 on its inner face. The enc 36 is, however, hinged to the side 33, as ind cated at 41, to swing into and out of position in the end of the casing. This end has a flange 42 at the opposite end from the hinge, for fitting against the inner face of the side 34. This hearing has a round opening for receiving the round trunnion 43 of the sash roller, while the'bearing 39 has a rectangular or flattened opening for receiving the placed in the casing by springing out the end 36, inserting the roller with the trunnion 28 in engagement with the hearing 29. Then the end 36 of the casing is closed.
It will he understood that there is sutii cicnt friction between the tia .ge 42 and the side 34 otthe casing to prevent accidental. displacement of the end 36 of the casing. The casing is arranged with its open side downward, and with the shield 9 extending toward the free edge of the side 33. Sufficient space is left between the free edge of the side 33 and the flange 12 of the shield to permit the passage of the screer.
The casing may be fixed in: piace in any desired manner. Preferably, this casing is made from a one-piece sheet of steel, and it is obvious that instead of hinging the end 86, the two ends might be made resilient enough to permit the entrance of the roller.
In combination. with the window casement and the sashes mounted to slide there-- in, of a screen for each sash, one screen be ing connected to the bottom of the lower sash and the other screen being connected to the top of the upper sash, said screens being connected at the inner face of the sashes, a
spring operated roller for the opposite end of each of the screens and upon which the screen winds, a casing for each roller, each casing being trough or channel shaped, and having at one end a. bearing for one trunnion of thejroller, the opposite end of each casing being hinged to swing outward, and the said end having a hearing for the other trunnion of the roller.
