To all whom it may concern: of a bracket D. D are arms radiating from Be it known that I, ALFRED SOAMEs, a subthis boss. They are bolted at their ends by V ject of the Queen of Great Britain, residing bolts E up to the ends of tubes E, which are at 16 Red Lion Street, Olerkenwell, London, securedtransverselyacross theframe by type- 55 England, have invented certain new and usemetal or other castings E ful Improvements in the Construction of Dy- O is the type-metal casting securing the namo-Electric Machinery, of which the folrings to the frame. lowing is a specification. The tubes E are first secured in proper po This invention relates especially to the consition to the frame. To effect this, the tubes 60 IO struction of electromotors in which a pile of are placed into holes or recesses which extend annular stampings is required to be accutransversely through the frame from one side rately centered in a frame which also carries of it to the other. The ends of the radial the shaft of an armature to be revolved witharms D of the brackets D are then attached in the annular stampings withanarrow clearby bolts E to the ends of the tubes E, and 65 ance or air-gap between them. both brackets are held in any suitable man- According to this invention the annular her in properposition relatively to the frame. stampin gs and the bearings for the armature- Type-metal or other suitable material is then shaft, or one or other of these, are secured to poured into the spaces between the tubes and the frame concentrically one with the other the interior of the recesses, and the tubes are 70 by means of type or such like metal or other so securedin position. Afterboth end brack suitable material cast between them and the ets D have thus been secured to the frame the frame. I bearing-bushes B are secured within the cen- Figure l of the drawings annexed shows an tral bosses D of the brackets D. To do this, end view, one-half in section, of the frame of the bushes are placed onto the armature-shaft 75 a machine so constructed. Fig. 2 is a lonand also passed into the central bosses D, one gitudinal section. Fig. 3 is a part longitudiof the brackets D being taken off from the nal section on a larger scale. Fig. 4 is a lonframe A and afterward replaced to allow of gitudinal section showing the way in which this, and while the shaft is held in any suit the stampings are held in place within the able manner in proper position relatively to 80 frame and concentric with the bearings at the *the frame type-metal or other suitable matime when typemetal is run into the space beterial is run into the spaces between the tween them and the frame. Fig. 5 shows a bushes B and the interior of the bosses, and modified form of ring used for holding the asthe bushes are thus secured truly in line with semblage of stampings. Figs. 6 and 7 show one another. After this has been done the 85 a modified way in which the brackets which ring-stampings O are secured in position withcarrythebearings forthe armature-shaft may in the frame. To effect this, the rings are be fixed to the frame. Fig. 8 shows an alterplaced onto a mandrel F. (See Fig. 4:.) The native way in which the bearings for the armandrel is carried by an axis G, which is of mature-shaft may be formed. the same size as the armature-axis. F is a 0 0 A is the frame, shown to be cylindrical, but fixed'flange at one end of the mandrel, and it might be square or of other form. F a loose flange at the other end. The rings A is an inwardly-projecting flange. are placed onto the mandrel between the B are the bushes or bearings for the armaflanges, and the loose flange is forced toward ture-shaft. the fixed flange by turning the nut II, which 9 5 O are the rings or stampings. They are screws onto a screw-thread cut around the shown as being circular on the exterior, but axis G. In this way the rings are all clamped they might be square or of other form. The togetherbetween the flanges. The axis of the apertures formed through these rings to remandrel is then placed into the bearings B ceive the field-windings are not shown. and is drawn endwise therein by a nut I, I00
The bushes B are held by type-metal or other which screws onto a screw-thread upon it and castings within a central boss D, forming part abuts against the end of one of the bearings.
In this way one side of the assemblage of rings is held against the inner face of the flange A.
A ring K is also placed against the other side of the assemblage of rings and is held firmly against it by clamping-pieces L, carried by the end of the mandrel. The ring has a groove formed around its outer circumference, as shown. A corresponding groove is also formed around the inner circumference of the frame. Other grooves A at distances apart from one another are also formed in the frame parallel to the axis. lVhile the mandrel is held in place in the bearings B, the frame is placed on end, with the ring K uppermost, and type-metal or other suitable material is cast into the space between the frame and the stampings O and ring K and into the several grooves above mentioned. When the metal has set, the mandrel is removed, leaving the stampings accurately centered within the frame and securely held in place.
Instead of grooves being cut around the ring K and frame for the type-metal or other material to be run into, as above described,
the outer circumference of the ring might be beveled, as shown at Fig. 5, and the portion of the inner circumference of the frame opposite to the ring be correspondingly beveled. Instead, also, of the ends of the arms D of the bracket D being bolted to the ends of tubes E, secured to the frame by type-metal or other castings, they might be bolted directly to the frame, or they might, as shown at Figs. 6 and 7, be made to enter recesses in the frame and be secured therein by a typemetal or other casting. Instead, also, of the bushes B being held within the bosses D of the brackets D by type-metal or other castings, they might be removable and held in place by a screw or otherwise, as illustrated at Fig. 8.
What I claim isl. A dynamo-electric machine in which an assemblage of sheet-metal rings and the bearings for the armature-shaft are secured to the frame concentrically one with the other by type-metal or other suitable material cast between them and the frame.
2. A dynamo-electric machine in which an assemblage of sheet-metal rings is secured to the frame concentrically with the bearings for the armature-shaft by type-metal or other suitable material cast between them and the frame.
3. A dynamo-electric machine in which the bearings for the armature-shaft are secured to the frame by castings of type-metal or other suitable material.
4. A dynamo-electric machine in which an assemblage of sheet-metal rings used for carrying the field-windi n gs is held in place within a frame concentric with the bearings for the armature-axis by type-metal or other suitable material cast into the space between its outer circumference and the frame and by one side of the assemblage of rings being held up to a flange formed around the interior of the frame by a ring which is held against the opposite side of the assemblage of rings by the typemetal or other casting.
5. A dynamo-electric machine in which the bearings for the armature-shaft are retained by castings of type-metal or other suitable material in brackets secured to the ends of the frame.
6. A dynamo-electric machine in which the bearings for the armature-shaft are carried by brackets held by bolts against the ends of tubes or blocks secured to the frame by castings of type-metal or other suitable material.
7. The hereinbeforedescribed method of securing an assemblage of sheet-metal rings side by side within the frame of a dynamoelectric machine concentric with the armature bearings such method consisting in mounting the stampings side by side upon a mandrel whose axis corresponds with the armature-axis placing the axis of the mandrel into the bearings and drawing it endwise until one side of the assemblage of rings bears against a flange formed around the interior of the frame and subsequently after placing the frame on end pouring in type-metal or other suit-able material into the space between
