VENTILATING APPARATUS;
No. 507,993. Patented NM. '7, 1898.
UNITED STATES PATENT OFFICE.
WILLIAM A. BURNHAM, OF IRVINGTON, NEW YORK.
VEN TILATING APPARATUS.
$IPEGIFIGATION forming part of Letters Patent No. 507,993, dated November '7, 1893.
Application filed April 1, 1893.
To all whom it may concern.-
Be it known that I, WILLIAM A. BURNHAM, a citizen of the United States ofAmerica, residing at Irvington, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Ventilating Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.
It is the object of my invention to'provide a simple and effective support for the gearing and shaft connections used for operating the ventilating sash of greenhouses and the like, by which the said operating mechanism may be adjusted to different positions by setting the parts of the said connections at any desired angle with relation to each other.
While my invention is intended especially for use in connection with either the roof or side sashes of green houses it will be understood that it is applicable to any place where a strong and readily adjustable support is desirable in order that the parts may be arranged at different angles relative to each other, if necessary, and then-securely clamped in place.
In the drawings, Figure 1, is a side view of the invention; Fig. 2, a plan, and Fig. 3, a longitudinal section; Fig.4adetail of a modification.
In the drawings the sash 1 has pivotally connected thereto a rod 2 which at its other end is connected with the arm 3, on the shaft 4. This shaft carries a segmental worm wheel .5 which meshes with the worm 6 on the hand shaft 7 extending to a convenient point to be turned by the hand wheel 8 thereon. These parts may be of any ordinary form combined as shown in substantially the well kn own way.
My invention relates particularly to the manner of supporting the shaft and gearing and of allowing the adjustment of the same in order that, if necessary, the wormwith its hand shaft may be fixed at any desirable point aboutthe periphery of the segmental gear to suit the special location in which the device is to be placed.
To the rafter or beam 10 is bolted a collar or bearing plate 11, having an enlarged opening 12 adapted to receive the shaft upon which the segmental worm gear is fixed. This collar has a flat bearing face or rim 13 against Serial No. 468,722. (No model.)
which fits the yoke plate 14 which has an opening of the size of the shaft and a yoked outer end 15 in which the worm shaft isjournaled. The opening in the collar is not only large enough for the shaft but also large enough to allow the clamping bolts 16 to pass through parallel with the shaft from the yoke plate in which the bolt heads are countersunk, to the clamping plate 17 which extends across the rear of the opening and overlaps the edge of the collar about the opening. The bolts are drawn tight to clamp the yoke plate and clamp plate securely to opposite sides of the collar by means of the nuts 18, and by loosening these it will be clear that the yoke plate and yoke will swivel orturn on the opposite faces of the collar and when the yoke has been properly adjusted it is then fixed by turning up the nuts and clamping the parts firmly together. By this construction I provide face plate joints between the parts, secure a strong and compact construction and one which will permit of ready adjustment and of a firm clamping effect.
The enlarged opening in the collar permits the adjustment of the yoke entirely around the shaft 4 and this form is advantageous for this reason, but I may secure the adjustment as shown in Fig. 4 by making curved slots 20 in the yoke and corresponding slots in the collar to receive the bolts. This will permit a limited adjustment without removing the parts but in order that the adjustment may be made entirely around the shaft the bolts must be withdrawn. In this as in the previous form the face plate joints are maintained.
I claim 1. In a sash worker, the combination with the shaft 4 its gear worm, worm shaft and connection to the sash, the collar or bearing plate having an enlarged opening through which the shaft 4'passes, the yoke plate having bearings for the worm shaft and fitting against the collar, the clamping plate extending across the enlarged opening and having its edges overlapping the rear side of the collar opposite the yoke plate and the bolts passing through the enlarged collar opening parallel with the shaft 4 and serving to clamp the yoke plate and clamping plate to opposite sides of the collar or bearing, substantially as described. A
2. In combinatiomthe sash, the shaft4 with" being iarranged to swivel about theshaft 4, connections thereto, the segment on the shaft, substantially as described. I I0 the worm and shaft the collar or hearing plate In testimony whereof I afiix my signature in to be attached to the rafter, the yoke plate presence of two witnesses.
