GLASS-SURFACING CAR OR TABLE.
Application filed January 22, 1924, Seria1 No. 687,708. Renewed March 31, 1926.
'tions, and is designed particularly for use.
in connection with the cars or movable tables employed in a straight away plate glass v surfacing operation for carrying sheets of glass, which aresecured to the-tops of the cars, beneath a series of grinding and polishing machines, such as those shown in the patent of John H. Fox, No. 1,492,974, dated May 6, 1924. The invention has for its primary objects; the provision of improved means for leveling up the cars or tables, so that the top of each table will be at the same level as that of the other tables, and so that the top of each table shall be in the same horizontal plane throughout its area, thus insuring a uniform surfacing effect by the grinding and polishing machines upon the glass sheet carried by the car; the provision of improved means for insuring the continuous and adequate lubrication of the wheels of the cars or tables, and in general the provision of a very simple and very rigid construction having the features of adjustment and lubrication as; heretofore referred to. ()ne embodiment of the invention is illustrated in the accompanying drawings wherein: 3 v
Figure 1 is a side elevation of the end of a car with the improvement applied thereto. Fig. 2 is a plan View of one of the wheel frames with a wheel mounted therein. Fig.
. 3 is a side'elevation of the construction of- Fig. 2. Fig. 4 is a section On the line IV IV of Fig, 2. Fig. 5 is an end view of one of the wheel axles. And Fig. 6 is an end elevation of an alternative device for bolding the axle in its various positions of ad-' justment.
Referring to the general arrangement of parts as indicated in Fig. 1, the reference numeral 1 designates the body portion of the car which is preferably a steel casting reinforced by suitable transverse and longitudinally extending'ribs 2 and 3. -At each corner of the car is a wheel frame casting 4 bolted or riveted to the body portion and carrying an axle 5 on which is mounted the wheel 6.
The casting 4 is preferably of the construction indicated in Figs. 2 and 3, having a central opening 7 in which the wheel is mounted and bearing portions 8, 8 resting upon the axle 5. In opposition to the bearing portions 8, 8 are a pair of caps 9,9 secured in place by the bolts 10, 10. In the particular construction illustrated, the axle 5 is held against rotation by means of the set screws 11, 11 (Fig. 4) which are mounted in the caps 9 and engage the axle.
The axle 5 has the portions 12, 12, which are mounted for rotary adjustment in the wheel frame ofi' center with respect to the bearingportions 13, 13 on which the wheel rotats,"so that by rotating the axle with respect to the wheel, the height of the center line of the wheel may be-adjusted vertically the axle being securely clamped in adjusted position by means of the set screws 11. This is of service in leveling up the table, and in order to facilitate the adjustment of the axle, one end thereof is squared as indicated at 14 and projects out past the wheel frame so that it may be engaged by a wrench. The portions 13, 13 of the axle have shrunk thereon a pair of bearing rings 15,15 which oppose other bearing rings 16, 16 shrunk into the wheel, suitable rollers 17 being interposed between the two sets of rings,
The bearings are lubricated from the end' of the axle by means of the central passage -18 which turns laterally as indicated at 19 so as to dischargeinto the grease-reservoir 20' at'the center of the wheel, such reservoir communicating with the spaces between the bearing rollers. A spring pressed cap 21 prevents the lubricant from leaking out at In order to pack-the the end of the axle. axle and prevent a loss of the lubricant on the outer sides of the bearings, the plates 22 are employed secured to the sides of the wheel by means of the bolts 22* such platesbeing provided with annular recesses carrying the felt washers 23. When the reservoir 20 is once filled with oil or'greasc, nb further attention to the lubricating of the wheel is required for a long period as the amount of lubricant used is relatively slight and the waste is reduced to a minimum.
The plates 21 with their washers also pre yent the access of dirt or grit to the bearmes.
Fig. 6 illustrates a holding de'vicewhich may be applied to secure the axle in its arious positions of rotary adjustment in place of the clamping bolts 11. When this plate 24 is employed, it is fitted over the squarcrl portion'14 at the end of the axle and is held against rotation with respect ttthe wheel frame by. means of one or more positions of adjustment.
-The advantages of the construction incigdent to its simplicity, adequate lubrication,
and easy adjustment will be readily ap parent to those skilled in the art.
lVhat I claim is:
1. The combination with a glass surfacing table or body, of a wheel frame at the corners thereof having perforated side pieces, axles for each Wheel frame'having eccentric ends seated in the perforations in the side pieces, wheelsjournaled on the axles between the side pieces, and clamping means for said eccentric ends for securing them In any desired position of rotary adjustment.
2. The combination with a glass surfae' ing table or body, of a Wheel frame at the corners thereof having perforated side pieces, axles for each wheel frame having eccentric ends seated in the perforations in the side pieces, Wheelsjournaled on the axles between the side pieces, and set screws mounted in the side pieces and engaging said eccentric ends for securing the axles in any desired position of rotary adjustment, In testimony whereof, I have hereunto subscribed my name this 15th day of J anu- ALBERT E. EVANS
