Lppllcation filed June 29, 1922. Serial No. 571,720.
This invention relates to what are known as Jordan engines used in the art 'of. refining stock in the manufacture of paper. The purpose of a Jordan engine .is to reduce or grind the pulp into small broken fragments.
Such engines include a shell in the form of a truncated cone from which inwardly project knives which cooperate with bars fastened to a truncated conical plug revoluble m on a shaft inside the shell.
This invention has to do with the shell and the'manner of originally producing the cutting surfaces or knives and'the manner of replacing them.
1 The .usual method at present is to alternately locate knivesand woods with occasional wedges all around the inner surface of the permanent shell, and then drive the wedges into position. The. elasticity and swelling of the wood is depended on to hold them in lace. I am aware that shells have been made with no woods and with knives integral with the shell, and that various expedients have been used to avoid the long- 2! process of accurately setting the knives and woods in the shell at the paper mill, either originally or for replacement.
he purpose of my invention is to provide a lining for Jordan engines which can be so completely built u in the machine shop where such shells, t eir knives or woods, are made and shi ped to the paper mill where it is to be use so that it can be put in place with great rapidity either originall to replace a similar shell the knives of w ich are worn down or to take the place of worn out knives and separators- I accomplish this purpose enerally by usin an auxiliary filling shel preferably consisting of thin sheet metal made either in one section to fill the entire shell of the engine or in a plurality of sections according to conditions. Inside this shell at the machine shop I build up the knives and woods, holding all in position until complete after which, as theresulting shell is relatively very light, it can be easily shipped to the factory and substituted for the woods and knives in a working shell or replace another similar linin in a permanent shell.
I prefer to use or my removable shell, a case of thin rolled steel of high tensile several each of truncated cone shape, or several of segmental form.
In the drawings, Figure 1 is a perspective View showing the permanentshell of a Jordan engine, with the plug and plug shaft removed and with one type of my removable lining shells inserted partway into the large end of the permanent shell.
Fig.2 is a diagrammatic view of the end of a form in which the thin metal case of my lining shell, preferably, is laced while the knives and separators are eing fitted and fixed in position at the machine shop. 7
Fig. 3 is a detail end section showing part of such a lining shell with its thin metal case, knlves, separators, and a wedge.
F1 4: is an outside view of part of a lining s ell in which the knives are spot-welded to the case.
F ig.. 5 is a diagrammatic verticals'ection showing the inside of a shell in which there is more than one set of knives and separators together with the platen of 'a press showing how knives and separators of each section can be forced orwedged into position all together. ii
Fig. 6 is a sectional detail showing part of the permanent shell and part of my lining shell, with one method of fastening them together.
Fig. 7 is a .section through a .permanent shell in the plane where the end of one of my sectional lining shells terminates, such lining shell being of the split type.
Fig. 8 is a plan view and-Fig. 9 an end view of a separator of a well known type.
Fig. 1() is a perspective view showing one segmental lini'ng shell and part of adjoining lining shell of one type, with one type of device for holding such segmental section while shipping.
In the drawings, A represents the base or frame of a Jordan engine as used in a paper mill, with the bearing C for the plug shaft and the permanent shell B supported by brackets 9 and 10 all in a well known manner.
F represents the preferred type of my lin ing shell and includes a case 19 of truncated conical form which may be made of steel or other suitable metal as thin as onesixteenth of an inch.
Into this case are forced the knives 30 and woods 31 as by means of wedges 32 in a wellknown' manner, preferably, while the case 19 itself is held rigidly in a suitable form such as indicated at L in Fig. 2.
After the lining shell F is completely built up in this manner; I prefer to spoteldat '33 from the outside the knives 30 to the case 19 whereby they are not only firmly held in position but make more rigid the entireconstruction.
Instead of using such wedges as 32 I may, as shown in Fig. 5, fix each of the several sets of knives and wedges, such as 40 and 41 or 30 and 31, in the following manner. Below the line YY is a section set in position and fixed in the same manner as that above theline X-X now to be described.
The knives 30 and woods 31 are placed accurately but lightly in position, reaching down to the line X-X which is a short dis tance from the line YY. After all are in place, the platen or plunger G of an hydraulic press is brought down upon the top ends of the knives and woods, and they are gradually forced down and into position so that eventually the reach the hue YY.
This might be done y an hydraulic press or by applying pressure in any other way as by hammering.
Fig. 6 shows one method of fasteninthe lining shell F to the permanent shell by a screw 35.
As shown in Fi 7, instead of usinga continuous lining su h as F I may use several shells one for each set of knives and woods each of such sections as H being split and havin its ends turned up'at 60 and 61 to hold t eknives and woods in position. After 'view of the same.
putting this in position in the permanent shell B, a fastenin wedge such as 45 is driven in to firmly old the parts H and B together.
Fig. 8 shows a plan view of a common form of se arator which may be of wood or other suita le material, and Fig. 9 is an end It will be observed that both views show a wedge-shaped and Ike stone construction well known in'the tra e. In such permanent shells there are often several sets of knives and separators ar ranged in truncated cones end to end, as indicated in Fig. 7 which shows (meet such sections.
Instead of building up each annular or substantially'annular section complete in the machine shop in a continuous case, such as shown in Figs. 1 and 2, or a split case such as H shown in Fig. 7, I may use a segmental construction such as shown in Fig. 10.
In Fig. 10, L represents a metal case of a shape to fit part of the inside of a permanent shell, such case having the large curved end 73, the small curved end 72 and the straight edges and 71. \Vith this construction I may use retaining bars of metal such as 74 and 75, which extend along each straight edge 70 and 71 and project inwardly therefrom, and I may attach them to case L by welding, riveting or by bolting, so as to make them firm.
Between these bars, the knives 79 and separators 7 8 are fitted by wedging or in other suitable manner. Bars 74 and 7 5'will hold them in position even when the lining segment is removed from t e form in which it is built up, but to avold possible displacement I prefer to use at each end'connecting bars such as M which may have nail points 80, which are driven into the separators 78, 78'which are proximate the bars 74, and 75 if such separators areof wood.
I show also passing through each bar such as 74 and 75 as well as through the edges 70 and 71 of case L, half- holes 76 and 77 which register, whereby bolts can be passed through into the permanent shell to hold the parts together if it is found necessary so to do. I
Instead of spot-weldin or otherwise welding allof the knives, suc as 7 9, to the case such as L, I may fasten some of the knives by means of screws such as 82 which pass through the case L into the back of each knife and I may leave others unfastened.
The fastening of the knives to the case by welding or otherwise, stiffens and strengthens the whole construction, but in many cases is not essential.
I claim:
1. In a Jordan engine having a permanent shell, the combination of a bodily removable lining shell, comprising a case of thin rolled steel of hightensile strength of a shape to fit'inside said permanent shell, knives and wooden separators fitted to the inside thereof, said knives being spot weld-ed to the case, and means to fasten the lining shell and permanent shell detachably together.
