Specification ofLetters Patent.
Patented June 12, rear.
hpplicationfiled ar -n is, 1916. sentimental.
To all whom it may concern." 7 Be it known that 1, PETER R. THOM, a citizen of the United States, and resident of Appleton, in the county of Outagamie and State of Wisconsin, have invented new and useful Improvements in Beating-Engines, of
which the following isa description, reference being had'to the accompanymg drawings,'which are a part of this specification.
The invention relates to improvements in beating engines.
In the paper making art the half or coarse.
pulp or other material is passed through a heating one to be shredded or reduced to a' finer pulp and in being worked, the material or stock is mixed with water to form a semi-liquid mass which is ordinarily contained within a centrally partitioned oval-shaped vat provided with a rotary, reducing member which extends transversely of a ortion of the vat on one side of the partition. The stock is caused to flow be-/ tween the'rotary reducing member-and a coacting knife member positioned below the reducing member. 1 The reducing member is in the form of a drum having projecting and longitudinally extending knives or blades which coact with the knife member in macerating or reducing the material. In order to cause a positive circulation of the pulp around the-Wm on each side of the partition a positive feed of the pulp to the reducing member, the vat adjacent to the knife member is provided with a front and back fall which gives the desired feed and circulation. I
The rotary reducing mber macerates the pulp material and moves it over the back fall and in thus moving the pulp material has a tendency to stick andis carried around bythe rotary member thus causing the pulp to pack and clog into the spaces between the lmives and around the member. This packa ing of the material interferes with the macerating work of the reducing means and increases the power required for o crating the machine, and is ob3ectionable in many other ways.
It is one of the objects of the present invention to obviate the before mentioned objectionable features and provide a beating engine with means for strlpping the greater portion of the pulp material from the retary member which has eased between the reducing means, and to root said material over the backfall to increase the circulation of the pulp in the vat.
A further object of the invention is to provide a beating engine which is of simple construction, is strong and durable and is .well adapted for the purpose described. I
With the above and other objects in view, the lIlVGIltlOIl'CODSlStS of the improved beating engine and its parts and combinations as set forth in the claims, and all equivalents thereof.
In the accompanying drawing in which the same reference characters indicate the same parts in all of the views;
Figure 1 is a top view of a portion of the improved beating engine, parts broken away to show the interior construction;
Fig. 2 is a longitudinal sectional view thereof taken on line 22 of Fig. 1;
Referring to the drawing, the numeral 5 indicates an oval-shaped vat which comprises the bottom portion 6, the side wall 7 and the longitudinally extending medial partition 8.; A rotary knife drum or reducing member 9 mounted on a transversely extending shaft 10 is positioned to rotate in one of the troughs 11 formed by the medial partition 8, and its knives 12 co-act with the stationary knives 13 mounted on the bottom portion 6 of the vat immediatel beneath the rotary member. An inclinedbottom portion or front fall 14: leads up to the stationary knives 13 and directs the pulp or stockthereto and an inclined dam or back fall 15 serves to assist in circulating the pulp or stock around the vet. The front; or nearest face 16 of the back fall to the rotary member, is concaved and the rear face 17 is inclined downwardly from the apex in a straight line. The concave face is curved on a radius whose axis is to the ,rear of the axis of the rotary member to space also flares upwardly so that the pulp material being forced continually I into the lower end will be easily pushed upwardly in the flaring space and wi l drop over the apex of the back fall and slide down the rear inclined face thereof and thus cause the pulp material toi circulate around the trough of the vat.
Thepulp material in engaging the lower edge of the deflecting member will, to a large extent, be withdrawn from the spaces between the knives and hub comparatlvely 'a small amount of pulp .will be carriedi v seen that the improved beating engine is of very-simple construction and Well adapted .for the purpose described.
What I claim as my inventionis 1. A beating engine, comprising a vat provided with a stationary reducing member and a back fall, a rotary member positioned above the reducing member and adjacent to the back fall, and a deflecting member interposed between the back fall and the rotary member for deflecting material from said rotary member toward the back fall.
2. A beating engine, comprislng a vat provided with a stationary reducing member and a back fall, a rotary member positioned above the reducing member and adjacent to the back fall, and a deflecting member extending transversely of the vat and located between the rotary member and the back fall and having its lower edge portion positioned close to the periphery of the rotary member. I
3. A beating engine, comprlsing a vat provided with a stationary reducing memher and a back fall, a rotary member positioned above the reducin member and adjacent to the back fall, an a deflect] member extending transversely of the vat and located between the rotary member and the back fall and having a lower curved portion the lower edge of which is positioned close to the periphery of the rotary memher to deflect pulp material therefrom into the space between the deflecting member and the back fall.
4. A beatin engine, comprising a vat, a
fixed pulp re ucmg member located in the lower portion of the vat, a back fall located in the vat and having a concave face adjacent the reducing member, a drum mount- 5. A beatin engine, comprising a vat, a
fixed pulp re ucing member located in the lower portion of the vat, a back fall located in the vat and having a'concave face adjacent the reducing member, a drum mounted in the vat and having longitudinally extending blades which co-act with the fixed reducing member in macerating material passing therebetween, and a deflectin member POSI- tioned between the drum and the back fall and extending downwardly at an angle toward the lower portion of the drum and and having a lower portion which curves toward thedrum and the lower edge portion thereof positioned closet'o the drum blades to deflect material therefrom between the deflecting member and the back fall.
In testlmony whereof, I aflix my signature,
in presence of two witnesses,
PETER R. THOM. Witnesses:
