. I ,4 Claims. 1 1
This invention relates to the construction of the frusto-conical plugs of Jordan engines such as are used for refining paper stock.
In these engines there is a frusto-conical shell from the inside of whichknives project inwardly and inside this shell revolves a plug from the outer curved surfaceofwhich project bars which cooperate withthe knives in the treating of the stock.
As suchbars on the outside of a plug revolve at a high rate of speed, they must be anchored in some way to the plug such as by having slots of more or less dovetailed or angular shape into which the inner edges of the bars fit, whereby the bars are locked in position as they must have been positioned by being pushed or driven in from thefends as shown in patent to Bolton, No. 1,829,630 of October 27, 1931, on which this invention is an improvement, or the bars may be held in place in the usual manner in which the plug is made up of annular bands under which hooks on the bars extend.
In any case, the space between adjoining bars is wholly or partially filled by separating members generally known in the trade as woods which are of wedge shape longitudinally but which diverge laterally. As a result of this divergence the centrifugal force tends to throw them out and it has been found highly desirable, if not necessary,to lock them in place in some way.
When and if applicant's separating members become worn, the wedge-shaped members can be driven out from the small end, whereupon his non-wedge-shaped members can quickly be taken out, while the metal "bars stay right in position so that replacements can readily be made. I,
In the Bolton patent above indicated, the bars are fastened or anchored tothe outside of the plug and in one form the sides diverge while the sides or side faces of the separators converge laterally, whereby, as the bars are held in place at their inside edges as by being driven into the slots from the large end, and the separators are also driven in from the large end each between adjoining bars, thewhole assembly is lockedin place. a V V In other forms of this construction there may be a longitudinal rib onfone or. both sides of each bar and a corresponding groovefon one or both sides of the separating member which is of wedge shape longitudinally but whose side faces may diverge laterally, the locking effect being the same when the separator is driven in from the large end; Y
. This invention is va multiple part separator made of two or more pieces, one of which is placed in position by putting it radially in between adjoining bars. This member need not be of wedge shape longitudinally but another. member is provided which is of wedge shape longitudinally and this when driven in position, locks the multiple part. separator in place,
I may use three or more pieces to make each separator, some with parallel or substantially parallel sides lengthwise, which can be put in position first and another or others whichcan be driven into position from the large .end or even from the small end.
Some plugs are made with long bars all of which extend from the large to the smallend and in such case my multiple part separators can extend the fulllength of the bars but, as most plugs are made with shorter bars alternating with the full length bars, I find it convenient to use one set of separators which I will call the small end separators which extend from the small end to the ends of the short bars and other sets of separators which extend only the length of the short bars and are positionedbetween them and the adjoining bars. These I will call the large end separators.
- The first set of small end separators extende ing fromthe small end to the short bars can,
each be made in one piece and can be driven in after the long bars are in position but before the short bars are in place, or these separators can be made in two or moreparts which can conveniently be put in position before the short bars are in place although they can be so made that after both the long and short bars are in place, one part of these small end separators can be pushed from the outside radially inward into position and the other part, which would be of wedge shape, can, then be driven in by suitable means in a general axial direction until the parts of such small end separator are firmly anchored in position between the long bars. v
As shown, the small endseparators are of a less height than'those between the short 'bars at'the large end. In the drawings, Fig; 1 is an isometric view of a plug embodying my invention.
Fig. 2 is a plan view of two long bars and a short bar with separators made according to my invention. v v
Fig. 3 is a side view in section of thebars and separators shown in Fig. 2,'with portions cut away to show the construction Fig. 4 is a sectional isometric view of a long and short bar with one form of my new separators.
Fig. 5 is a view similar to Fig. 4 of a modification.
Fig. 6 is a view similar to Fig. 4 of another modification.
Fig. 7. is a view similar to Fig. 4 of my new separator as used with a modified form of bar.
Fig. 8 is a view similar to Fig. 4 of still another modification in which the separator is made of three sections.
Fi 9 is a view similar to but reduced in size from Fig. 4 of another modification, of a two part separator.
In the drawings A represents a plug body having a curved surface I in which are dovetail shaped slots 2 for seating the long bars B and 8 for the short bars 0. 3 is the large end and 4 is the small end of thesplug A.
Each long bar B at the top or outside II has parallel sides and at its inside or bottom edge I2 is of dovetail shape as shown, and is seated in a slot 2. Sides l5 and I6, as shown, diverge and then come together to form shoulders l8, l8 at the working or cutting outside H which terminates at the top or cutting, face I3 representsthe end of a bar B at the large end and 4 represents the end of a bar B at the small end. 7
The short bars C have a top or outside part 2| and an inside or bottom edge 22, diverging sides and 26, and a cutting face 21. 23 represents the small end and 24 the large end. The bottom edges 22 of bars 0, as shown, enter the short dove-tailed slots 8 which. are spaced between the long bar slots. 2,. these slots and the short bars 0 being spaced between the long slots and the long bars B.
As shown in Figs. 1, to 6. the separating members at the small end are indicated by D and as shown, are of one piece while those at the large end which are positioned between. the short bars C and the long bars B are made of multiple parts and as an assembly are indicated by S.
As shown in Fig. 4, each of these separators S is made of two parts namely and 3|. These are shown as extending from the curved surface I of the plug up to near the tops of the bars. The top, bottom and side faces of the member 30, all run in. lines which are parallel, whereby the top face 32 and bottom 33 are parallel and. inside face 34 is at right angles thereto while all parts of the face 35 which. come in contact with a bar conform to the side face of that. bar and lie in similar parallel lines. For convenience, I will call these parts the straight shaped parts.
It will be noted that the bottom face 33 of this part must be narrow enough to go between the shoulders I8, l8 of the adjoining bars so that this part canbe pushed or placed in position between adjacent bars from the outside radially inward.
The other member 3| has a top face 36 and a bottom face 31 which are parallel and an inside face 38 which corresponds with and fits adjoining face 34 and an outside face 39 which fits the adjoining side face of a bar.. The difference between the parts'30 and 3| is that the part 3|, as shown, is of wedge shape longitudinally and after the part 36 is put in position, the wedge shaped part 3| must be driven in between part. 30 and the adjacent bar so that when once. in position, it looks the parallel part 30 as well as itself firmly in place. Iv will call parts similar to 3|, the wedge shaped parts.
In Fig. 5 is shown a two part separator wherein the straight shaped part 40 has faces which lie in parallel lines in a manner similar to the part 36 while the wedge shaped part 4| is of wedge shape longitudinally, the difference being that the adjoining faces 42 of 40 and 43 of 4| lie in the same plane but that plane slopes from left to right inward so that the inside face 44 of 46 is, as shown, much narrower than the inside face 45 of 4|.
In Fig. 6 is shown another construction in .which the straight shaped part is parallel and the wedge shapedv part 48 is tapered, but the adjoining faces are angular as shown instead of each being in a single flat plane.
In Fig. 7 is shown a two part separator H made up of straight shaped part 66 and wedge shaped part 6|. In this case the bars G are shown with parallel sides but having at the bottom or inside 52 a bead which fits a suitable slot such as 50 in the body F and a top 5|, sides 53 and 54, lengthwise of each of which are suitable ribs 55 and 56.
In this case, the two part separating members indicated by H are made up of one straight shaped member 68 with faces which run in parallel lines and another wedge shapedv member 6| which is tapered in a manner similar to those hereinbefore described, the difference being that each part has a groove such as 62 or 63 which engages a rib such as 55 or 56 whereby when the part 66 is placed in. position and the part 6| is driven into place, the ribs entering the grooves hold the whole assembly in place.
In Fig. 8, I show a plug body A and bars B and C such as. those shown in Figs. 1 to 6, but the separating member indicated by K is made up of two straight shaped parts namely 16 and,
H whose faces lie in parallel. lines and wedge shaped part 12 which is tapered longitudinally. In this case, the parts 10 and H are first put in position and then the wedge shaped part It is driven into place.
In Fig. 9, I show a plug body A and, long bars B, B, such as shown in Figs. 1 to 6, with a sepe arating member L made up of the part 86, of which. part of one face 8| fits a diverging face 89 of one bar B and with a bottom face 82 narrow enough to go in between. the shoulders of bars B, B. The top face 83 of member L extends the full distance between the top parts 96, 90 of bars B, B, and has a recess 84 and a face 85 which is so made that when it is associated, with a face 86 of. the other bar B, the wedge shaped part 81 can be driven in as shown between the faces 85 and 86, resting on top of. face 82 of the plug thereby locking the part in place as well as wedge part 87 and thus the whole multiple part separating member L.
By laterally is meant sidewise I claim:
1. For use with a Jordan engine plug having a frustro-coni'cal body; a multiple part separating member of keystone shape laterally and of wedge shape longitudinally one part having. its side faces lying in substantially parallel .planes and another part with side faces which converge from the large towards the small end of the multior. transversely.
