SHA'VINGS AND SA'WDUST SEPARATOR.
Specification of Letters Patent.
Application filed April 29, 1916. Serial No. 94,392.
W. BREN- other refuse collected by an exhaust fan system, and which refuse is adapted to feed furnaces, stoves and the. like. I
The object of my invention is to provide means for efficiently and efiectively separating saw-dust from larger particles of waste wood collected by means of the well known rotary exhaust fan system, from planers, saws, and other wood-working apparatus, that saw-dust may be utilized for valuable commercial purposes; a further object of my invention is to provide means for the.
separation of the saw-dust from the larger particles of wood in order to allow the same to more efficiently feed the fires in the heating plant, as saw-dust does not contain the high combustible value which is prevalent in chips and shavings, thereby saving fuel. I attain these objects by the mechanism illustrated in the accompanying drawing, in which A Figure 1 is a side elevation of the entire device, Fig. 2 is a plan of the same, and Fig. 3 is a detailed front elevation of the separating hopper with the screen casing removed, showing the screen.
Similar characters of reference refer to similar parts throughout the several views.
Referring to the drawing, A is a vertically disposed cylindrical refuse receiver, suitably mounted upon an elevated platform or rorf B of a building by means of a suport r p The refuse from several wood-workin machines or other apparatus which give 0% waste material, is conveyed through a large pipe D by means of a strong 'air current traveling in the direction indicated by arrows 2 and which is delivered by means of a common rotary exhaust fan in the buildin below. This part of the apparatus is ol and does not form part of my invention.
The said refuse is depositedi'n the receiver A from the pipe D which tangentially enters the same, thereby causing the refuse to whirl in the direction indicated by arrows 3, and by means of centrifugal force, the
' same is inclined to follow the inside surface of the receiver, at the same time entering a hopper E by force of gravitation, the said hopper being attached to the bottom of the received A, substantially forming part of the same, and concentric therewith.
A finely woven screen F is fixed in an aperture in the hopper E, shown in Fig. 3
of the drawing, and in broken lines in Fig. 1, and around this screen a casing or saw-dust receiver G is secured to said hopper. Through this screen the saw-dust is sieved, as indicated by arrows 4, by means off the centrifugal motion of the refuse caused by the circular air current described in the foregoing paragraph, and at the same time, the remainder of the refuse which cannot escape through the screen F, passes downward through a pipe H as indicated by arrow 5, and-into a'furnace or other suitable place of disposal.
. From thesaid receiver or casing G, the
saw-dust is carried through a pipe J in the direction indicated by arrows 6, by means of the same air current, and into a second vertical cylindrical receiver K, mounted upon a support L, in the same manner as the receiver A.
The pipe J also tangentially enters the saw-dust receiver K, thereby giving the sawdust the same circular centrifugal motion as the refuse inthe receiver A, and as indicated by arrows 7 From the said receiver K, the saw-dust is carried by the air current, together with the aid of gravity, through a hopper M and a pipe N as indicated by arrow 9, and into a suitable container of a class desired.
It and T are air exit pipes on the receivers A and K respectively, and are for the purpose of allowing surplus air to escape, in order to eliminate possible congestion. inside the said receivers.
The pi es D and J are shown broken in the drawing in order to show that they may be of any suitable length.
The receiver K and the hopper M may be eliminated without" departing from the spirit and scope of the invention, although the device operates more efliciently when it is provided with the same.
Patented May a, rare.
lid
' ing a partial distance therearound, flush with and having the same contour as the sides of the hopper, an external casing secured to the sides of the hopper around the screen and constituting a substantial space memes between itself and the screen, a saw dust outlet pipe communicating with and extend- 15 ing from said casing, and a refuse outletpipe communicating with the lower end of the hopper, all substantially as set forth.
In testimony whereof, I have hereunto afiixed my signature to this specification in 20 the presence of two subscribing Witnesses.
