REVOLVING WINDOW-BASH.
SPECIFICATION forming part of Letters Patent No. 514,773, dated February 13, 1894.
Application filed August 24, 1893.
' To all whom it may concern:
Be it known that I, PHILIP S. RIDDELLE, a citizen of the United States, residing at Woodstock,in the county of Shenandoah and State of Virginia, have invented new and useful Improvements in Revolving Window-Sashes, of which the following is a specification.
This invention has for its object to provide new and improved window-sash attachments carried by the slides.
The invention also has for its object to provide novel mechanism carried by the slides and susceptible of adj ustability for facilitat- 1ng the raising and lowering movement of the sash, and for preventing rattling thereof in the window frame.
The invention also has for its object to provide novel slide-bars for carrying the rotating sash, whereby spring-yielding anti-friction rollers and mechanism for adjusting the tension of the roller springs can be housed in the slide-bars, and the latter may be light in weight while possessing the requisite strength and durability.
The invention also has for its object to provide the slide-bars which carry the rotating sash with novel locking devices for securing the sash in its closed position, or at any desired height.
To accomplish all these objects my invention involves the features of construction and the combination or arrangement of devices hereinafter described and claimed, reference being made to the accompanying drawings, in
Figure 1 is a side elevation of a windowframe and sash provided with iny invention. Fig. 2.is a detail perspective view, showing portions of the window-frame, sash-frame,.the slide-bars, and the locking devices. Fig. 3 is a horizontal sectional viewtaken on the line 33, Fig. 1. Fig. 4: is a detail vertical sectional view on a'larger scale to illustrate the SerialNo. 483,950. (No model.)
construction of the slide-bars and the adj ustable anti-friction rollers. Fig. 5 is a plan view, looking at the inside of one of the slidebars, and showinga portion of the sash swung at an angle to said slide-bar; and Fig. 6 is a detail perspective view of the key employed to adjust the tension of the springs which operate on the anti-friction rollers.
In order to enable those skilled in the art to make and use my invention,I will nowdescribe the same in detail, referring to the drawings, wherein The numeral 1 indicates a window-frame, and 2 a sash-frame having on its vertical edges the rigidly attached metallic wear plates 4: which are preferably secured in place by screws 5, Fig. 5. The sash-frame 2 is journaled centrally between its upper and lower ends to metallic slide-bars 6 through the medium of horizontal pivot pins 7 which extend through the side rails of the sash-frame into suitable orifices in the slide-bars in such manner that when the sash-frame is not held by the locking devices hereinafter explained, such sash-frame can be revolved in a vertical plane, for the purpose of enabling the window glass or glasses to be quickly and conveniently cleaned. The revolution of the sashframe on the horizontal pivot pins 7 also enables the sash to be swung into different positions to secure the desired ventilation of a room in abuilding, or of a railway car, or vehicle having my invention applied thereto. 8 5
The slide-bars 6 are each formed of a channeled iron, the longitudinal channel in which is utilized for the reception of rack-bars 8 adapted to be reciprocated inopposite directions through the medium of a key 9, Fig. 6, 0
inserted through the key-hole 10, Fig. at, when the sash is swung at an angle to the slidebars, for example as shown in Fig. 5. The
'key is provided with. two parallel pins 12 which respectively engage the teeth 13 of the 9 5 rack-bars 8, so that when the. key is in engagement with the said teeth and is rotated or turned, the rack-bars aremoved longitudinally in opposite directions. The upper and lower ends 14 of the rack-bars bear upon flat 'or leaf springs 15, which are rigidly" secured at one end to the slide-bars 6, as at'16, while their free extremities bear against the tail- .pieces 17 of roller-carrying levers 18 which are pivoted to the slide-bars through the medium of pivot pins 19. The levers 18 carry anti-friction rollers 20 which are bevel faced or conoidal, and are adapted to ride upon guide-rails 21, Fig. 3 in such manner as to force the sash-frame outwardly against the parting strip 19 of the window frame, as will be understood by reference to Fig. 3, the outside strip or bead for the upper sash being omitted from the drawings. The action of the springs on the tail-pieces 17 of the rollercarrying leverslB enables the rollers 20 to yield in a direction parallel with the plane of the window glasses, and, consequently, the slidebars, with the sash-frame journaled thereto, can be easily and conveniently raised or lowered at all times, notwithstanding swelling or shrinking of the window-frame or sash-frame while shrinking of the sash-frame or windowframe does not result in rattling, because the spring-pressed anti-friction rollers compensate for shrinkage, and steady the sash-frame in the window-frame. The toothed ends of the rack-bars 8 are cut away as at 23, so that they can move opposite each other in the same plane, and thus enable the channeled slide bars to be made comparatively narrow.
The slide-bars 6 are secured to the lower ends of metallic bands 24, or other suitable suspension devices which engage springdrums journaled in the window-frame in juxtaposition to the top portion thereof in such manner that when the slide-bars are not held under restraint, the spring-drums operate to wind up the bands 24, and thereby elevate the window-sash.
The window-sash is locked in its closed position, or at any desired height through the medium of one of the slide-bars, for which purpose one of the side flanges of such slidebar is provided with a series of locking notches 26, with any one of which a springbolt 27 is adapted to engage. The bolt 27 is adapted to slide horizontally in a bolt-case 28 having a flange 29 provided with screwholes by which to secure itin proper position to the window-frame. The belt carries a pin 30 which extends laterally through a slot 31 in the bolt-case, and upon the projecting part of this pin bears one end of a spring 32 which is carried by the bolt-case, so that the spring tends to force the bolt 27 outward into engagement with the locking notches 26 of the slide-bar. The bolt is also provided with a pin 33 which extends laterally through the slot 31 at the side opposite the pin 30, and against this pin 33 bears one end of a leverarm 34, pivoted at its opposite end, as at 35, to the bolt-case 28, and provided intermediate its ends with a lateral stud 36, against which bears one arm 37 of a bell-crank lever 38 which is pivoted at its angle, as at 39, to the bolt-case 28. The other end of the'bellcrank lever projects outside the windowframe, and, as will be understood by reference to Fig. 3, carries a finger-piece 41 which is pivoted intermediate its ends to the arm 40,
as at 42, for the purpose of forming a tailpiece which is provided with a stud 43 adapted to bear against the inner edge of the arm 40 when the finger-piece is in the position shown in Fig. 3, whereby pressure on the finger-piece in a direction toward the sash-frame will rock the bell-crank lever 38 and cause its arm 37 to act on the stud 3G and swing the lever-arm 34in the proper direction to retract the bolt 27 from engagement with the toothed slide-bar 6, enabling the sash to be raised or lowered. The object of the lever-arm 34 and bell-crank lever 38 is to secure a considerable length of movementof the bolt 27 by a comparatively small movement of the fingerpieee 41; and the object of pivoting the finger-piece 41 so as to provide a tail portion which carries a stud 43 is to enable this fingerpiece to swing the bell-crank lever 38, and at the same time permit the finger-piece to be swung outward away from the window-sash, so as to place such finger-piece out of the path of the sash-frame when it is desired to revolve the same on the horizontal pivot pins 7.
The construction and arrangement de-,
scribed places the locking mechanism for the notched slide-bar in a very compact form, so that it does not present any very extended part, while at the same time the requisite movement of the locking-bolt is obtained through the medium of a comparatively small finger-piece which is susceptible of being swung out of the way when the sash is to be revolved.
In order to lock the sash to the slide bars, and thus prevent it from being revolved until intentionally released, I provide the lower end portion of each slide-bar with a rock-shaft 44 having a latch 45 projecting in one direction,and a stud 46 projecting in the opposite direction, and bearing against a fiat spring 47. The latch 45 is adapted to engage a recess or slot 48 in the lower end portion of the wearplate 4 when the rock-shaft is turned in the proper direction, thereby locking the sash to the slide-bar.
The rock-shaft is provided at one end with a finger-piece 49 which can be swung in the arc of a circle for turning the rock-shaft to cause the latch 45 to enter or leave the recess or slot 48. \Vhen the rock-shaft is turned in the direction required to release the latch 45 from engagement with the recess or slot 48, the spring 47, acting on the stud 46, holds the rock-shaft against accidentally turning.
The rock-shafts on the respective slide-bars are the same in construction, and thereforea description of one is deemed sufficient for both.
When the slide-bars and sash are held slightly elevated, or at such height that a persons band could be inserted from the outside to manipulate the finger-piece 49, it is desirable to prevent the latch 45 from being entirely disengaged from the recess or slot 48, while the sash is more or less elevated, especially where the sash is raised a short disfrom being moved the required extent to turn the rock-shat t and entirely disengage the latch from the recess or slot 48. But when the sash is tightly closed down, the projection can enter a recess or notch 53 in the inner bead or strip 52, and consequently the finger-piece can be'moved the required extent to entirelyv disengage the latch 45 from the recess or slot 48, whereupon the sash-frame can be revolved on the horizontal pivot pin 7. I also provide notches or recesses 54 in the beads or strips 52 injuxtaposition to the finger-piece 41, so that when the sash is raised to a considerable height, the projections 50 can enter such notches or recesses 54 for releasing the sashframe and permitting it to be revolved or 1'0- tated.
When the slide-bars 6 are suspended 'by the bands or suspension devices 24, as hereinbefore explained, it is only necessary to provide a single locking device for locking the sashtrame to one of the slide-bars, as for example the toothed slide-bar; but where suspension bands or devices are not employed it is desirable to employ a finger-piece 49 with a projection 50 on each slide-bar, so that when the sash and slide-bars are elevated and the sash is revolved, the projections 50 can enter the notches or recesses 54, and thus prevent each slide-bar from falling downward out of proper position.
In a sash-frame which is adapted to revolve on a horizontal axis, and at the same time be raised and lowered through the medium of slide-bars, the anti-friction rollersand the adjusting mechanism for varying the pressure of the anti-friction rollers are very desirable features, in that they render the sash susceptible of being easily raised and lowered, notwithstanding swelling of the sash-frame or the window-frame; while if the wooden parts shrink, rattling and disagreeable noises are prevented, because the spring-pressed rollers compensate for shrinkage and steady the sash-frame in the window-frame. The free extremities of the leaf springs 15 have a tendency to spring in a direction away from the bottom walls of the channeled slide-bars, but they are held under restraint by the end portions 14 of the slides 8, and the pressure of the springs on the tail-pieces 17 of the rollercarrying levers 18 is increased if the slides 8 be moved toward the pivots 19 of said levers 18, and conversely the pressure of the springs on the-tail-pieces 17 is diminished when the slides 8 are moved in a direction away from the pivots 19. By thismeans the pressure of the conoidal anti-friction-rollers 20 against the rails 21 is increased or dimin- H ished as occasion may demand.
I have illustrated my invention as applied to a single sash, but obviously it may be applied to both sashes.
- The faces of the slide-bars6, contiguous to the wear-plates 4, are provided with longitudinal depressions, and the wear-plates are correspondingly shaped to accurately fitthese depressions, as will be clearly understood by reference to Fig. 3, for the purpose of providing perfect joints between the slide bars and the wear-plates. This construction does not interfere with the revolution of the sashframe, because the slide bars are susceptible of yielding toward the sides of -the windowframe when force is applied to one end of the sash-frame for the purpose of turning it on its pivot pins.
Having thus described my invention, what I claim is 1.'The combination of slide-bars carrying spring-yielding anti-friction rollers, springdrums having suspension bands connected with the slides, means for varying the pressure of the rollers against parts of'the window-frame, a rotatable sash journaled to the slide-bars, a lock for engaging and locking one of the slide-bars, and a lock for locking the sashes to one of the slide-bars, substantially as described.
2. The combination of slide-bars carrying spring yielding anti-friction rollers, means for varying the pressure of the rollers against parts of the window-frame, a rotatable sash journaled to one of the slidebars, a lock' for engaging and locking one of the slide-bars,
and a latch mounted on one of the slide-bars for engaging the sash-frame and having a finger-piece provided with a projection 50 adapted to enter a recess or notch 53 in a part of the window-frame whereby the sash-frame cannot be revolved until the projection enters the recess or notch, substantially as described.
.3. The combination with slide-bars, and a sash-frame carried thereby, of levers pivoted to one of the slide-bars and carrying an antifriction roller, a leaf-spring acting on the roller-carrying lever, a slide movable more or less over the leaf-spring to vary the power exerted thereby on the roller-carrying lever,
and means for moving the slide longitudinally on the slide-bar, substantially as described.
4. The combination with slide-bars, and a sash-frame carried thereby, of levers pivoted to the slide-bars, carrying anti-friction rollers and having tail-pieces,leaf-springs acting on the tail-pieces of the levers, and slides movable in opposite directions and engaging. the leaf-springs to vary the power exerted thereby on the roller-carrying levers, and means for moving the slides in opposite directions, substantially as described.
5. The combination with longitudinally channeled slide-bars, and a sash-frame carried thereby, of levers pivoted in the channels of the slide-bars and carrying anti-friction rollers, leaf-springs acting on the rollercarrying levers, and slides arranged in the channels of the slide-bars and movable in opposite directions to more or less engage the leaf-springs, and means for moving the slides in opposite directions, substantially as described.
6. The combination with slide-bars, and a sash-frame carried thereby, of levers pivoted to the slide-bars and carrying anti-friction rollers, leaf-springs acting on the levers and oppositely movable slides provided with toothed portions and bearing against the leafsprings, and a device for engaging the toothed portions of the slides to move them in opposite directions, substantially as described.
7. The combination with slide-bars, and a sash-frame journaled thereto, of a rock-shaft mounted on one of the slide-bars and having a latch to engage a part of the sashframe, and a finger-piece 49 having a projection adapted to enter a recess or notch in a part of the window-frame whereby the sashfranie cannot be released and revolved until said projection enters said recess or notch, substantially as described.
8. The combination with a slide-bar having a longitudinal notched portion,and a revolving sash journaled to said slide-bar, of a bolt 27 adapted to engage the notches oi the slidebar, a pivoted lever-arm 34 engaging a part of the bolt, a bell-crank-lever 38 having one arm engaging a part of said pivoted leverarm, and a finger-piece 41 pivoted to the other arm of said bell-crank-lever, substantially as described.
9. The combination with a channeled slidebar having a series of locking notches 26 and containing pivoted levers 18 carrying antifriction rollers 20, leaf-springs 15, and slides 8 movable more or less into engagement with said springs, of a bolt 27 adapted to engage the locking notches of the slide-bar, a pivoted lever-arm 34 bearing against a part of the bolt, a bell-crank-lever 38 having one arm engaging a part of the lever-arm, and a fingerpiece 41 pivoted to the other arm of the bellcrank-lever, substantially as and for the purposes described.
