9 Claims. (c1. 308E484) My invention relates to a' pillow block, and more par- 2 Fig. 4 is a fragmentary sectional view, taken substantially in the plane of the line 4-4 of Fig. 2;
Fig. 5 is a perspective view of a plate forming half of the pillow block;
Fig. 6 is a vertical axial sectional view through the pillow block shown in Fig. 2, illustrating the edge metal block .of the character indicated, wherein the parts of the pillow block are formed as duplicates of each other and will interfit to provide a sturdy pillow block.
Other objects andvarious features of novelty and invention will be hereinafter pointed out or will become apparent to those skilled in the art. '7
v Brieflystated, in a preferredform of the invention the pillow block consists of a pair of sheet metal plates secured in face-to-face relationship. The plates are duplicates of each other and each-plate is provided with an annular outwardly directed housing flange forming one half-of the housing for a hearing, such. as an. antifriction bearing. Each plate, at each transverse end, has outstanding bearing foot for supporting the pillow block on a support. Between the foot bearing flange and the upstanding plate from which the foot is turned, there is an outwardly pressed reinforcing rib preferably of generally rectangular form so as to provide a generally inverted V-shaped reinforcement when viewed in section. Each of the outstanding feet has a bolt hole so that four bolts, .or the like, may bevemploy'ed for adequately-supporting the pillow block on a pillow block support.
In one form of the invention, the plates have edge metal bearing surfaces for engagement with the pillow block support, and these edge metal bearing surfaces are preferably flush with the bottoms of the feet turned out from the upstanding plates. In another form the plates have outwardly ldirected supporting flanges for direct engagement with the pillow block support, and these flanges provide a very substantial support for the pillow block. The bottoms of these outturned bearing flanges are substantially flush with the bottoms of the feet formed on the pillow block halves so that the feet and the outturned supporting flanges are flush on the bottom.
The bearing in the housing may fit directly therein or there may be a bushing interposed between the housing and the bearing, such bushing being formed of resilient material, such as rubber, or the like.
In the drawings which show, for illustrative purposes only, preferred forms of the invention:
Fig. 1 is a top plan view of a pillow block illustrating features of the invention;
Fig. 2 is a view in axial elevation of the pillow block shown in Fig. 1;
Fig. 3 is an edge view of the pillow block shown in quarter section and viewed substantially in the planes of the line 3-3;
surfaces forming a support for the pillow block, and also showing the hearing as being mounted directly in the bearing housing; d
Fig. 7 is a fragmentary view similar to Fig. 2 illustrating a modification; V
Fig. 8 is a sectional view, taken substantially in the plane of the line 88 of Fig. 7;
Fig. 9 is a fragmentary sectional view, taken substan tially in the plane of the line 99 of Fig. 7.
In said drawings, the pillow block consists of a pair of upright plates 56 secured together by any suitable means, such as bolts, screws, rivets, or the like, 7, as Will be understood. Since these plates are exact duplicates to each other and may be formed by the same dies, the description of one plate will suffice adequately for both. The plate 5, for example, is first pierced, as indicated at 8, and the metal then forced outwardly into the form of an outwardly directed annular flange 9 forming half of the housing fora bearing in the pillow block. If desired, the extreme end of the flange 9 may be turned inwardly, as indicated at 10, to form adequate housing and support for the bear-ing. These annular flanges 9 are preferably generally spherical in form at the inside to permit some bearing self-alignment, as will be-understood.
Each plate at the bottom has .an outwardly \directed flat foot flange 11 each of which has a hole 12 therein for reciving a securing bolt, or the like, for securing a pillow block on a support. Between the upstanding plate 5 and the outwardly directed foot flange 11 there is ,a substantial pressed out reinforcing rib 13, which may be and is shown as generally rectangular in horizontal cross section, as clearly shown. This reinforcing rib 13 is pressed out of metal of the plate 5 and of the foot flange 11, and extends upwardly to about the horizontal plane through the axis of the hearing, as will be clear in Figs. 2 and 3. These reinforcing ribs 13 being integral as they are with both the feet 11' and the upstanding side of the plate carrying the feet will give adequate support to the plate and prevent distortion thereof during operation of the pillow block. These reinforcing ribs 13 on the two plates 5--6 cooperate with each other and form a generally inverted V-shaped reinforcement, as shown particularly in Fig. 4. Thus, this hollow, generally triangular V-shaped truss gives the pillow block great strength against overturning on its feet 11 which feet, as stated, are securely held down to securing bolts or the like. It will be seen that these reinforcing ribs 13 are preferably inclined, each converging generally toward the center, as shown particularly in Fig. 2. These ribs are parallel to the tangents to the annular flanges 9 below the center of the housings. Thus, these ribs give adequate cross support against bending of the upstanding plates in a direction transverse to the ribs 13.
In the form shown in Figs. 1 to 6 the plates have edge metal bearing surfaces 14 for engagement with the support for the pillow block. These edge metal surfaces 14 are preferably flush with the bottoms of the outturned foot portions 11 on each plate so that the pillow block is adequately supported onthe edge metal surface 14 and on the outturned flanges 11.
In the form illustrated in Fig. 3 the bearing comprises an outer ring, an inner ring and antifriction bearing members, such as balls. The outer ring 15 is not mounted directly in the housing, but in a bushing such as a bushing 16 of resilient material, such as artificial rubber or V 3 the like. Thus, with such need not be finished at the outside and yet will be adequately supported and due to the rubber bushing there will be some self-alignment of the bearing in the housing.
In the form shown in Fig. 6, the outer ring 17 is of generally spherical outer contour and fits within the generally spherical housing surfaces 18 formed'by the outturned bearing flanges 9, as will be clear. While some self-alignment will be provided for that form shown in Fig. 3, some self-alignment will also be possible with the form shown in Fig. 6. However, it is preferable to align the bearing in the housing and then secure the two plates securely so as to turn the bearing in position.
In that form shown in Figs. 7, 8 and 9, the plates are exactly the same as heretofore described, except that instead of having the plateswith edge metal surfaces in contact with the support there are outwardly directed bearing flanges 20 which extend outwardly slightly more than the extent to which the annular housing flanges 9 extend. These bearing flanges 20' could be integral with the foot flanges 11, but as illustrated are separated therefrom and they form adequate plate bearing surfaces for the pillow block on the pillow block support. The bottoms of the flanges 20 are preferably flush with the bottoms of the bearing feet 11 on the plates so that the entire pillow block will be supported in flush fashion on its support.
It will be seen that in all forms, the plates have adequate supporting surfaces on the support and the supporting sunfaces of either edge metal or of outturned flanges 20, may be flush with the bottoms of the securing feet without danger of having the feet snap off by drawing down the securing bolts too tightly. The bearings may be mounted directly in the housings, as indicated in Fig. 6, or on rubber bushings or the like, as indicated in Fig. 3. In any event, the bearings are adequately supported within the housings. The annular housing flanges 9 themselves form extending reinforcements for the plates which resist bending or other distortion, and the reinforcing ribs 13 pressed out of and joining the metal of the plates and the supporting feet form strong integral reinforcements against tipping of the bearing on its bearing feet and to resist other distortion of the plates or the feet.
While the invention has been described in considerable detail and preferred forms illustrated, it will be understood that changes and modifications may be made within the scope of the invention, as defined in the appended claims.
