MOUTHPJECE FOR PNEUMATIC coNvEYERs.
SPECIFICATION forming part of Letters Patent No. 64:6,490, dated April 3, 1900. Application filed November 12, 1897. Renewed February 7, 1900. Serial No.-4, il4. (No mqdel.)
Be it-known that I, HARRY A. DEERY, a citizen of the United States, and a resident of the city of Philadelphia, State of Pennsylvan'ia, have.invented certain new and useful clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. a
My invention relates'to certain improvementsin conveyers, and has reference more especially to the inlet box or mouth situated fully set forth hereinafter.
In the accompanying drawings, Figure 1 is a sectional elevation of the inlet end of a pneumatic conveyor constructed in accordance with my invention. Fig. 2 is a perspective View of the same, illustratingalso a suctionble pipe or tube; and Fig. 3'is a sectional elevation, drawn to an enlarged scale, to illusvice. Fig. 4 representsa slight modification of construction shown in Fig. 3, the forward The apparatus is intended for the removal of all classes of finely-divided material of moderate weightsuch as light refuse, chips, sawdust, grain, meal, (ho-which may be ined for the removal of a top layer: or layers'of such material-as, for instance, the removal of accumulations of foreign matter from the upper surface of large filters-where it is desired that such materialbe removed without disturbing the sand or similar material which forms the filter-bed.
I Referring to the drawings, A represents'an exhaust-fan connected by a flexible or sectional conveyor-pipe B of any ordinary construction to the piped end I) of the inlet-box O, the inlet-box being flattened and of much greater width than the conveyer-pipe, assuming a shovel-like form, as shown in Fig. 2. The lower forward end of the inlet is in the form of a-thin blade 0, which may readily slide and be pushed under the material to be removed and facilitates its entrance to the inlet. As the inlet-box is to be, moved around by hand and it may on some occasions be.
: material to be conveyed away.
desirable to alter the inclination of the box,
while still maintaining the lower edge of the boxin a horizontal line," the forward lip c is formed'of sheet metal, which may be slightly bent to effect this object. Immediately under the lower plate of the inlet-box isa horizontal plate D, which forms a base for the box and is adapted to travel in a horizontal line at the lower level of the-layer of the material to be removed andforms a base and support for maintaining the box in proper position as it istraveled forward into the material. Side plates d: at each edge of the box serve to form, with the plate 0 and D, a space or compartmentfor the passage of air from the open rear end and also act to prevent the entrance of any material. into said space or compartment. The rear edge of the plate 'D has a slight upward curve, as d, which will )revent the entrance of'an material to said compartment if at any time it becomes necessary to withdraw the inlet-box to the rear. 1
In the lower plate of the inlet-box are aseries of openings e, which place said box in communication with the compartment below it, and a further series of smaller openings e.
may also be provided in said plate as additional air-passages in the event of the clogging of the openings e;
The upper plate c.of the-inlet-box terminates at a point somewhat to the rear of the plate 0 in an upwardly and rearwardly curved flangef, and in said plate 0' at a point immediately to the rear of the flange are formed a series of openings 9, through which air may pass to the interior of the box.
The conveyor-pipe between the inlet-box and the suction-fan may be of rigid or flexiblo material; but in all cases I prefer to employ a flexible tube or connection with the pipe-section b of the inlet-box,so that said box may be freely moved into the path of the As a convenient means of operating the box I employ an elongated handle or bar H, connected at one .end-bya socket h to the boxand at the opposite end by a ring it to the flexible pipe-section, the handle being preferably of sufficient length to permit the operator to conveniently grasp it and manipulate thebox.
In operation the exhaust-fan is operated 1 inlet-box and through the openings e e and therewith and g from the bottom and top of the box, and the latter is then traveled in the direction of'the' large arrow, Fig. 3, in the path of the material ,being moved. The forward lip c willact to guide the material into the mouth of the box, at which point it will meet. the blast of air induced by the fan into the mouth of the box and will become thoroughly intermingled drawn up through the conveyer-pipe to the point of discharge. The lower portion of the material will meet'a blast of air entering through the openings e, and the upper portion of the material will meet a second blast of air entering through the opening g. The effect of these air-currents, traveling as they do between the surfaces of the box and the top and bottom of the body of material being'operated u'pon, will keep such material from contact with the surfaces of the box,avoidiug undue friction and clogging and keeping the material practically suspended in a central of such contact with the sides of the box or conyeyer-pip'e as would tend to retard the operation.
It is clear that'small openings may also be provided, if desired, in the sides of the box for the: induction of side currents of air, al-
' though these are not in all ,cases desirable,
owing tolthe danger of clogging and choking from contact with material.
,Havingthus described my invention, what -I claim, and desire to secure by Letters Patent, is-
1., An' inlet-box for conveyers, comprising 1 pper and lowerperforated plates,and a baseplate arranged to form with the lower plate position without danger a compartment or passage for the introduc- 0 tion of. air, substantially as specified.
2. An inlet-box for con'veyers, comprising in combination, a lower plate having a forwardly-extending flauge or lip and perforated at a point to the rear of the forward edge of said flange or lip, a base-plate having an upwardly-curved rear end and forming with said lower platea compartment for the passage of air to the perforations of the plate, and an upper perforated plate having a. flanged forward edge, substantially asspecified.
3. A movable inlet-box for conveyers'comprising a lower plate, 0 having perforations, e, a base-plate,1), side plates, d, forming with the plate, 0 and the base-plate a compartment for the passage of air through said perforations, an upper plate, c,haviug perforations, g, and an upwardly-extending flange, f, situated at the forward end of said plate, 0', substantially as specifie' 4. An inlet-box for conveyors comprising an open mouth and rear tube, forwardly-protruding lower lip, a lower longitudinally-disposed channel, the upper and lower walls of the box each having perforations provided at or near their forward edges for permitting and directinga current of airinwardly along theleugth of the inner surfaces of said walls, the saidperforationsin said lower wall opening into the said lower longitudinally-disposed air-channel, snbstantiallyas described.
In witness whereof I have hereunto set my hand this lOth day of November, A. 1). 1-897.
