SASH POSITION INDIGATING DEVICE Filed March 5, 1927 2 Sheets-Sheet 2 Ill/mill! I Q mw mm Y Q Z1 m'lliam R0 Patented Apr. 29, 1930 UNITED S AT -s WILLIAM ROY, or
IRVINGTON ON HUDSQN, NEVI YORK, ASSIGNOR TO LORD 86 BURN- HAM G M ANY, or'mvrnero'n'on HUDSON, new YORK, A conronarrouor- NEW YORK I 'SASH-POSITEONf-ENDIGAEINQ DEVICE Application filed March -;5,
This invention relates generally to sash operating mechanism .for greenhouses or other structures employing such apparatus for ventilation, and relates particularly to a new andimproved distant-control gage adapted to indicate at onepoint such as an operating station, the relativeposition or eX- tent of sash opening, at'another point which may be at a distant or unseen point or location.
In sash actuating mechanism now commonly employed and heretofore used for ventilation, it has been necessary to count the number of theturns ofthe operating wheel or lever, or to observe theactual position of the sash,'if possible, in order to ascertain or gage the extent of the sash opening, and in order to know when thesash was approaching the limits of the extreme open or closed position. WVhere the operating station is some considerable distance from or below the sash, it is at times very difficult toobservethe-sash movementor position; at night itispractically impossible to observe thesash position without lighting the structure. In greenhouses or other structures, where carefully regulated ventilation andtemperature control is requireditis very desirable to, provide indicating means whereby the'sash opening may be. carefully gaged and controlled.
.Inproviding a sash position indicator, it is also desirable to have it so arranged as who readily adjustable for use under different conditions, for variable maximum sash openings for use with different types and'gear ratios of sash operating mechanisms. v
One ofithe' objects of this invention. is to provide agage or indicatorwhich shows the relative sash position or opening,- and which will overcome the difficulties above referred to. V
A further object is to; provide an indicator forsash operatlngme'chan sm whichmay be readily applied-to the actuating means at. the operating station oteither new or .old installations.
A further objectisstoapitovide a sasl1. ,.p o-
sition indicator having parts soarranged; and constructed; as i to gbe readily Adjusted, :and adapted. 1or;.-use;':1mder different condit ons,

with different types of sash actuating mechanism, .for. a wide range of maximum sash opemngs.
A further object is to provide an inclicator which is neat-,compact and readily assembled.
A further object is to provide a sash posi tion indicator in. which .theindicator pointer maybe initially readily shifted and adjusted .to indicatethe true sash position.
Still a further object isto provide in .a sash position indicatorreadily adjustable limit, indicator blocks or stopsso arranged that they may be moved to different positions alongfthe path of movement ofthe indicator hand or indexpointer. Bysuch an adjustable feature a given indicator maybe used to show vmaximum sash opening over a wide and varied rangeofmovement of the sash actuating mechanism, froma relatively few turns to a relatively large number of turns.
Afurther object is to provide a sash position indicator which'may also serve as a limit stop to arrest further movement of the sash when it has reached the desiredtully opened Orshut position. For purposes ofillustration, one preferred form or a selected embodiment of my inven tion is shown in the accompanying drawings and described in the following specification.
In the drawings 1- Figure 1 is an elevation partly broken a-way-,showing the indicator and an actuating '1 Figureyo s anenlarged-view showing a ..portion of a greenhouse sash !and sash actu.
s ng: ech n s t ith t 'eee 9pm Figure 5 is an enlarged elevation partly in section showing the position assumed by the indicator when the sash is open as shown in Figure 5.
Figure 6 is an enlarged section on the line 66 of Figure 1, showing a detail of the adjustable indicator blocks or stops.
As shown in Figures 1, 2, 3, and 4 a sprocket wheel 20, when manually moved bya handle 38, serves as the operating means for moving the sash 46 through the usual rack 49 and pinion connection, and the usual worm and gear drive within the casing 42. The pinion of course would be mounted on the line shaft 43, the pinion not being shown in the drawings. The upper sprocket 41 is mounted on the worm shaft, and the worm gear and pinion are fixed on the line shaft 43. The upper sprocket 41 is driven by the lower sprocket 20 through the chain 39; It is to be understood that various other well known types of sash actuating mechanism may be employed.
As shown in Figures 4 and 5 the casing 42 for the worm and gear mechanism is mounted on the bracket'44 which is in turn secured to the bar 45. The upper side of the sash 46 is pivot-ally supported adjacent the ridge bar 50. One end 51 of the rack bar 49 is pivotally secured to the sash 46.
The sprocket wheel 20 is shown fixed on one end of a shaft 15, which is rotatably supportedin a barrel like sleeve or bearing 13, which is in turn integral with a sleeve 10 disposed normal to the sleeve 13. The sleeve 10 is adapted tobe adjustably positioned on a post 11 by means of the adjusting bolts '12. The sleeves 10 and 11 serve as an adjustable supporting bracket for the hand sprocket 20, and for the sash position indicating mechanism to be later referred to.
The indicator or gage for showing the relative sash position or opening comprises in general a movable member such as the disc 24, having a pointer 36, adapted to move over 7 a scale forming the frame 28 of the indicator.
' The indicator disc 24 is rotatably mounted on the bolt 26 which in turn is fixed on the crossbar 39 extending between the legs of the U shaped frame 28. A boss 37 (see Fig. 2) is formed at the rear of the bar 39 to receive the threads of the bolt. Such a construction permits the disc 24 to be readily ably and detachably supporting the indicator disc 24 and pointer 36.
The peripheral edge of the arcuate disc24 is provided with teeth 25, adapted to engage and mesh with the thread 19 formed on the shaft 15. The inner portion of the sleeve 13 is of an enlarged diameter thus leaving a space as 'at 23 around the threaded portion '19 of the shaft 15. The lower toothed portion of the indicator disc 24 extendsthrough which it is used.
Other suitable for controlling and limiting the endwise 1 movement of the shaft 15. As shown, the sprocket 20 is fixed on one end of the projecting shaft 15, and a collar14 is fixed on the other end of the shaft 15 by a locking member 17. tion 19 of the shaft 15 extends for a distance on each side of the portion normally in mesh with the teeth on the periphery of the indicator member 24, in order to permit of a certain endwise adjustable movement of the shaft which might be utilized to correct or set the position of the indicator pointer 36 to correspond with the sash position. Such an endwise movement of the shaft 15 would rotate the indicator disc 24 without requiring removal of the bolt 26 or the rotation of the Preferably, the threaded por sprocket 20, and thus constitutes an addi tional means of adjustment.
In order to make it possible to use given sash position indicator with varying types of sash actuating devices and for a wide range of maximum sash openings, it is necis provided with aseries of slots 29, 30 in order to permit the indieatorblocks or stops 31, 32 to be adjusted to different positions corresponding to fully open and shut position of the sash for the particular installation, in
For example, in one installation, the gear ratios and the maximum movement of the sash may be such that the fully open and shut position of the sash would require the indicator limit block 31, (marked 0 for open) and the block 32 (marked S for shut) to assume the positions shown in F igures4 and 5 to show the fully open and shut position of the sash; whereas, for another installation a different gear ratio or more limited maximum sash opening, would require a change in the position of the limit stop blocks to a different position, such as that indicated in Figure 4*, by the dotted position of the indicator blocks at 31 and 32, to indicate respectively, the fully open and closed sash position.
Figure 6 shows more clearly the detail construction of a preferred form of the adjustable indicator limit blocks. The block 31' bearing the indicating character isthreaded to receive'a screw 40, which extends through the slot 29 or 30 in the main frame 28; a washer 41 is shown between the screw head and the back of the frame.
' As a means of mounting the frame, a base 33 is provided which extends between the legs of the frame and to the rear thereof. The indicator frame is detachably mounted on the top of the sleeve 13, and is held in proper position by the screws 34;. Other suitable means may be provided for detachably mounting the indicator frame.
If desired, the indicator blocks may be provided with projections which at the limit of travel engage the pointer 36, or other part of the movable member 24, so as to function as limit stops to arrest any further move ment of the sash actuating mechanisnr Figure 4 is an enlarged view partly in section of the indicator showing the position of the parts when the sash is shut as shown in Figure 4:. Figure 5" is a similar view showing the position of the parts when the sash is fully open as shown in Figure 5. Prefer- (iii ably, an indicating mark 35 is placed on the frame 28, to indicate the half-way position between the fully open and shut position.
The sash position indicator is simple in construction, is readily assembled, and is capable of adjustment for use in different installations of varying character.
A sash position indicator of this character, makes it now possible to locate the operating station at a distant point out of the view of the sash; such a position may be in a separate room, such as the work room adjacent the end of a greenhouse or other structure where employed.
While one preferred form of the invention has been shown and described for purposes of illustration, various changes and modificaarcuate indicator disc detachably and rotat-,
ably supported on the frame, said disc having teeth in the periphery thereof adapted to mesh with the threads of the sash, an indicator pointer movable with the disc and indicator limit blocks adjustable in the frame.
