REGISTER AND VENTILATOR.

Application filed. February This invention relates to registers and tion of the valve operating means.

Among the chief objects of the invention are :first, to provide an-operating handle forthe valve that will lie substantially flush with or below the face of the .register when the valve is closed, whereby the packing and transportation of a number of such registers is greatly facilitated in that such devices may be very closely packed, one upon another, without danger of injury to the valve operating handle.- Again, the construction of the handle is such that it will operate the valve whether it is pivoted adjacent its long edge or its short edge. These and other objects and advantages will appear to any one skilled in the art from a reading oft-h following description:

In the drawings Fig. 1 is a front elevation of a register or ventilator embodying the invention;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a section on the line 3+3 of Fig. 2;

Fig. 4 is a section similar to the section shown in Fig. 2 but showing the valve axis reversed so that the valve will swing at right angles to the axis indicated in Fig. 2.

1 represents a perforated face plate, the cross-bars between the perforations being preferably corrugated. The edge of the face plate around the perforated portion is depressed to provide a set back border portion 2, forming in effect a reinforcing rectangular frame- 3 represents the valve provided to open and close the air passages through the face plate. 4 is a separate rectangular frame, which may be provided at the back of the perforated portion of the face plate and held thereto in any desired manner as by means of fastening screws 5-5. Ordinarily, the valve is pivoted at one edge to swing in the rectangular frame 4. In Figs. 2 and 3 the pivotal construction is such that the valve may be swung on its long edge, whereas in Fig. i the axis is shifted so that the valve will swing on its short edge. 6 represents one of the pivot pins for the valve and this may be engaged with the long edge or may be shifted to engage with the shorter edge of the valve according to the position that the register is to 10, 1926.

occupy on the wall. This idea of shiftable valve axis is Well known in the art and involves no part of this invention, although I have referred to it herein because my improved valve operating means is so designed that 1tv will operate the valve equally well whether the latter is pivoted on its long edge or its short edge.

I will now proceed to describe the Valve operating means. 7 represents a flange mounted at the front of the valve 3 near one corner and secured thereto in any suitable manner as by spot welding. 7 is a longitudinal. slot in the flange 7. The operating member is in the form of a crank, the axle portion of which is indicated at ,8. At the outer end ofthe axle is an operating handle arranged at right angles thereto, while at the inner end of the axle is a lever 10, also at right angles thereto. The lever 10 has an offset 11 which enters the slot 7. Movement of the handle 9 is transmittedthrough the axle 8, lever 10, and offset 11 to the valve 3 to cause it to swing to its closed, or its open, posit on. To frictionally hold it in any pos1tion,.j provide an exceedingly Simple and effective construction as follows:

The axle portion 8 is preferably deeply seated in one of the corrugations at the back of the face plate 1, close to one corner there of (see Fig. 3). 12 is a clamping plate held by a clamping screw 18. One end of the clamping plate 12 overstands the axle 8. The screw 13 is accessible at the front of the register so that by turning the same, the pressure of the clamping plate on the axle may be varied to furnish the desired frictional tension to properly hold the valve. By reference to the drawing it will be apparent that the operating means will make operative engagement with the flange 7 to operate the valve 3 whether or not the latter is hinged to swing on one of its longer edges or on one of its shorter edges. This of course is of great benefit and advantage.

I claim:

1. In a register, a perforated face plate, a set back border extending around the same, a valve, means for pivoting said valve adjacent to the back of the face plate to swing on either of a plurality of axes, means for operating said valve comprising an axle pivotally mounted on the back of the face plate and projecting through a. side of the set back border adjacent to one corner thereof, a handle on the outer end of said valve arranged in one operative position to stand substantially parallel with the border and back of ,the plane of the outer faceof the perforated faceplate and'wholly within the field of said set back border extending around the same, a valve, means for pivoting said valve adjacent to the back of the face plate to swing oneither of a plurality of axes, means for 'operating said valve comprising an axle piv- 'otally mounted on the back of the face plate and projecting through a side of the set back border adjacent to one corner thereof "a handle on the outer end of said valve arranged in one operative position to stand substantially parallel with the border and back of the plane of the outer face of the perforated face plate and wholly within the field of said border, means of connection between the other end of the axle and said valve, whereby motion of the axle will be transmitted to the valve to operate on either of the pivotal axes of the latter, a friction clamp engaging said axle, and an adjusting screw therefor, the head of said screw being accessible at the front of said perforated face plate for operation.

3. In a register, a perforated face plate, a setback border extending around the same, a valve pivoted at one edge adjacent tothe 7 and wholly within the field of said border,

an angular crank at the inner end of said axle, and a sliding connectlon between said 'crank and said valve adjacent to one corner of thelatter.

4. In a register, a perforated face plate, a

set back border extending around the same,

a valve pivoted at one edge adjacent to the back of the face plate, ope-rating means to swing said valve comprising an axle pivot- A ally mounted on the back of the face plate at one corner thereof, the outer end of the axle projecting through the side of the set back border, a handle at the outer end of said axle arranged at substantially right angles thereto and arranged in one position to lie close to the border and substantially back of the plane of the outer face of the face plate and wholly within the field of said border, an angular crank'at the inner end of said axle, a sliding connection betWeen' said crank and said valve adjacent to one corner of the latter, the pivot for the valve being shiftable from one edge of said valve to another edge thereof at substantially right 7 angles to the first.
