c. HENDERSON SHEET sEPARATo BLOWER' Fixed Feb. 1. 1922 @www Patented pr.- 1, 1924.

ra arises issn e FF@ ef Frasidi- @efrr SHEET-SEPARATQR BLD?? Application led February 1, 1922. Serial ro. 533,188.

To all whom t may concern.'

Be it known that l, Cani. HENDERSON, a citizen of the United States, residing at Chicago, in the county ofk Cook and State of Illinois, have invented certain new and useful Improvements l in Sheet-Separator' Blowers, of which the following is a specification.

This invention relates to means for positively insuring the injection of air or other separating medium into a pile of sheet inaterial to facilitate separation ofthe sheets regardless of the angle at which the sheets may lie.

One object of this inventionis to obviate the necessity of adjusting a sheet separator nozzle in connection with a pile of sheet material in which the sheets lay at different angles.

Another object is to provide a simple and eflicient sheet separator nozzle for directing jets of air at different angles to insure separation of sheets in the pile regardless of the angles at which the dierent sheets in the pile may lie.`

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which- Figure 1 is a side elevation, partly in section, of my sheet separator nozzle, the section being taken through one set of nozzle apertures directed at an angle downwardly and taken in the plane of line 1-1 of Figure 2, a pile of sheet material also being shown to illustrate operation of the device;

Figure 2 is a front elevation of the same nozzle;

Figure 3 is a top plan view ofthe same nozzle;

Figure 4 is a fragmentary sectional view talendin the plane of line 44 of Figure 2; an

Figure 5 is a fragmentary sectional view taken in the plane of line 5 5 of Figure 2.

rihe various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the figures of thefdrawings, it will be noted that the blower or nozzle takes the form of a casing 10 having two vertical partitions 11 and 12 therein converging forwardly of the nozzle. of the nozzle is provided v`with three sets 13, 14 and 15 of apertures arranged in different vertical planes and communicating respectively with chambers 16, 17 and 18 formed in the casing 10 by the partitions 12 and 11. Jdir or other separating medium is applied tothe casing 10 through any suitable connection 19.

Referring particularly to Figure 1 a pile 2O of paper is'shown, the sheets of which may be in a horizontal plane as indicated at 21 or may curveupwardly as indicated by dotted lines 22, or may curve downwardly as indicated by dotted lines at 23. Obviously, a single nozzle having a single opening or a plurality of openings pointing in the saine direction and directing jets of air in the saine direction could not possibly eiiiciently separate sheet material lying in the various angled positions indicated. To make possible the separation of sheets by a blower under such conditions and without making adjustment of the nozzle to accommodate the peculiar lay of different sections of the pile, or of different piles having sheets lying at dilierent angles, l have provided the blower or nozzle herein shown in The facer which the apertures 13, 14 and 15 are all y directed in different general directions. For example, the apertures 14 are directed in horizontal lines, as shown in Figure 4, and air jets issuing therethrough would be effective in separating sheets lying horizontally, as indicated at21 in Figure 1. Apertures 13, as shown particularly in Figure 1, are directed angularly downwardly and are particularly effective in separating sheets curved upwardly at the edges, as indicated at 22 in Figure 1.

rlhe apertures 15, as shown, particularly in Figure 5, which extend angularly Vupwardly through which jets of air are forced, lind particular application in cases where the sheets are curved downwardly at the edges, as indicated at 28 in Figure 1. Accordingly the jets of air issuing from the three sets of apertures 13, 14 and 15 are eifective for separating the sheets regardless of the angles lin which the sheets generally lie, for such jets of air are directed straight into the sheets and between same so that ice l minimum resistance is oti'ered in lifting the sheets from the pile.

It is my intention to cover all modifications oi" the invention falling Within the spirit and scope of the following claims.

I claim:

l. A separator for separating sheets in a pile comprising a casing one Wall of which is provided with apertures extending in different direetions whereby jets o1c air issuing therethrough are directed at angles With respect to each other.

2. A separator for separatingpsheets in a pile comprising a casing one Wall of which is provided With apertures extending in different directions and partitions in said casing for forming compartments communicating With said apertures.

3. A separator for separating sheets in a pile comprising a casing having a Jfront Wall, and vertical partitions extending rearwardly from said front Wall forming conipa-rtments in saidcasing, Said front Wall having apertures communicating with said different compartments and extending at different angles with respect to each other whereby jets of air issuing therefrom will he directed at angles with respect to each other.

Signed at Chicago, Illinois, this 28th day of December, 1921.

CARL HENDERSON.
