J. E. LUDWIG PNEUMATIC CONVEYER Filedct. 29, 1928 j Patented Jan. 26, 17932` 1 UNITEDvv s 'rA TES PATENT OFFICE i JOHNE. LUDWIG, or DETROIT, MICHIGAN, AssIGNOR To'NnwCOMB-DAVID COMPANY, f
\ INC., OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN PNEUMATIC oONvnYER Application led October 29, 1928. Serial No. 315,649.
Thepresent invention pertains to a novel pneumatic conveyer for the purpose of cari rying material such as shavings, dust and waste away from working machinery and dischargeitat some suitable point. i j
The principal feature of the invention `re sides in the factthat the movement of material through the Vconveyer is produced `not j only by suctionmeans at the dischargingend proper of sections cally, providing an opening In each joint,
j tion of discharge. vided at the discharge end of the conveyer or pressure means at the opposite endl,ibut also by a `device for throwing air into the `.conveyer proper at intermediate points therei of in the direction of discharge. Such a constructionfis obtained by building the conveyer joined together telescopisecuring a conduit to the conveyer proper in a manner to communica-te with these openings, and blowing air into the conduit in the direc- An exhaust fan vis proproper for drawing the material therethrough, and the movement ofthe material is j obviously assisted by the air that ischarged f into the conduit.
The invention is fully disclosed by of example in the following description and in,-
the accompanying drawings in which` Figure l is a side elevation of the apparatus j i j Fig. 2 is a fragmentary longitudinal section thereof on an enlarged scale; and
Sis atransverse section on the line F3 of Fig. 1.
"by use of like characterswhich are employed Reference to vthese views will now be had to designate corresponding parts throughout.
l j j In Fig. l the conveyer proper is illustrated Lil) as beingcomprised of a number of sections l each having one end 2 received in an adjacent section and its other end`3 receiving the other adjacent section. The receiving end is somewhat enlarged as at 4 through a comparatively short extent of 'its perimeter toform f i an opening 5 between the enlargement and thereceived end `5 adjacent thereto. The
` openings are preferably formed in alignment atthe lowest point ofthe conveyer con@ j duit.
\ y A conduit 6 consisting also of telescopically `nel cross section as clearly shown in Fig. Sand openings in thebottom j said air conduit.
joined sections is supported preferably beneath the conveyer `proper in such a manner as to enclose the openings 5 and thereby communicate with them. Theconduit is of chanis secured to the conveyer proper by means'of `marginal flanges 8 rivetedV as at 9 to the sections-l. Y i r i 4At the discharge end of the conveyer i proper constituted by the sections l is profvided an exhaust fan or blower 10 for drawing material through the sections l and'discharging it. Thesections l may be tapped as at 11 at selective points in order to com- `municate`with branches leading fro-m various machines.V At the opposite end of the conduit 6 is provided a fan or blower 12 for j charging air into the conduit in the direction towardsthe fan l0. The air from the `fan l2 Obviously enters the sections l through n the Openings 5 and assists in carrying the material to the point of discharge.
Although a specicembodiment of the invention has beenillustrated and described, it will be understood that various alterations "-3 in the details of construction may be made Y without departing from the scope of the in` vention as indicated by the appended claim.
What I claim is A pneumatic conveyer comprising an en- :i
closed main conduit having permanently free- L thereof, said main conduit having a series of apertures for connection of branch intakes thereto, an air conduit secured to said main conduit in a manner to enclose `sai-d j openings and communicate therewith, and means for forcing air into JOHN n LUDWIG j icaV
