Feb. 1, 1955 J. GRZYBOWSKI TIL-TABLE WORK-SUPPORTING TABLE FOR TOOL MACHINES Filed Oct. 12, 1953 INVENTOR.
United States Patent TILTABLE WORKSUPPORT]NG TABLE FOR TOOL MACHINES John Grzybowski, Chicago, Ill.
Application October 12, 1953, Serial No. 385,340
4 Claims. (Cl. 143132) The present invention relates to tiltable tables for sup porting work in tool machines such as drill or band saw, for the purpose of making bores at an angle 1n the work when a drill is used or making bevel or miter surfaces when a band saw is employed. The general class of machines with which the present invention may be employed is represented by the disclosure in my Patent 2,604,127, granted July 22, 1952.
Another object of the present lnvention is the prov1s1on of means in a tiltable table of the character ndicated for locking the table in any desired angular position.
A still further object of the present invention is the provision of means for indicating the degrees of angularity when the table has been tilted to one or the other lateral directions.
With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.
In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views;
Fig. 1 is the plan view of the present table;
Fig. 2 is an enlarged cross sectional v1ew through the table, taken on line 2--2 of Fig. 1, illustrating 1n elevation the supporting and tilting means for the table;
Fig. 3 is a fragmentary rim elevatlonal v1ew of the table, showing means for indicating the degrees of angularity when the table is tilted laterally in e ther direction;
Fig. 4 is a cross section, partly in elevat on of the supporting means for the table, the view having been taken substantially on line 44 of Fig. 2; and
Fig. 5 is a cross sectional view on l1ne 5- 5 of Fig.
Referring in detail to the present drawmg there is shown therein base 10 upon which the table and 1ts appurtenances are supported. Integrally formed with and upwardly projecting from said base 10 1s collar 11 provided with a square bore through which post 12 wh1ch 1s square on transverse cross-section is extended mto said base 10 for upright shifting movement for raismg or lowering the table assembly relative to said base 10. Screw 13 driven through said collar 11 engages said post 12 and maintains the same in its adjusted pos tion. The square formation of post 13 and square bore in collar 11 prevent rotary shifting of post 12 and of the table assembly.
Positioned upon the upper end of said post 12 1s collar 14 which is rigidly connected with post 12 by means of a pair of opposed screws 15.
The upper end of said post 12 is provided with recess 16 for seating therewithin horizontal shaft 17. Sa1d shaft 17 is extended through said collar 14.
On loosening screws collar 14 with shaft 17 may be disengaged from post 12 and the table assembly removed therefrom.
The invention further includes a pair of bearings 18, within which shaft 17 is supported, said bearings being adapted for shifting movement upon said shaft 17 in either direction. Said bearings 18 are provided with lateral wings 19 through which screws 20 are passed for afiixing said bearings to the underface of table 21.
Integrally formed with the forward bearing 18 is sleeve 22 through which said shaft 17 passes. One or more screws 23 driven through said sleeve 22 is adapted to en 2,700,992 Patented. Feb. 1, 1955 gage shaft 17 for the purpose of locking table 21 in its forwardly shifted, retracted or tilted positions.
It is noted that shaft 17 is made stationary with relation to collar 14 and post 12. Pins 24 driven through the lower end of collar 14 are made to rigidly engage said shaft 17 and firmly bind it to collar 14. Table 21 and bearings 18 are capable of longitudinal shifting movement upon shaft 17 as well as of angular shifting movement thereon when screw 23 is loosened.
Adjacent the rim said table 21 is provided with a downwardly depending semi-circular plate 25, at the upper end of which the same is provided with flange 26, through which a plurality of screws 27' are driven to engage table 21 for the purpose of maintaining plate 25 in a rigid relation with said table 21. Of course, said shaft 17dis passed through said plate 25, as is seen in Figs. 2 an 3.
A plurality of calibrations 28 made upon theforward face of said plate 25 along the rim thereof indicate the degrees of inclination of table 21 as said calibrations 28 come in alinement with pointer 29, which extends in an upright direction from plate 30. Said plate 30 is supported upon base 10 and affixed thereto by means of screws 31.
Dovetailed into table 21 above flange 26 and plate 25, and adjacent the upper face of said table 21 is strength ening plate 32, which is affixed to table 21 by means of screws 33.
Along their rims said flange 26, table 21 and plate 32 are provided with slot 34 for selectively receiving therewithin wing 35, which extends vertically in an upward direction from said shaft 17. Said shaft 17 is slotted for receiving the lower end of said wing 35. Rivetsor screws 36 passing through shaft 17 and lower end of said wing 35 rigidly connect the latter with said shaft.
When table 21 remains in a horizontal position and is shifted upon shaft 17 toward said wing 35, the latter will enter slot 34. In this manner table 21 will become interlocked with said wing 35 and through. it with shaft 17, so that said table 21 will be incapable of any angular shifting movement. When however table 21 is retracted from wing 35 the former will become disengaged from said wing 35, the retracted position of the table being indicated by dotted lines in Fig. 2. In the retracted position the forward bearing 18 will come in contact with stop pin 37, thereby limiting farther rearward shifting movement of table 21 and its appurtenances.
When in the retracted position table 21 may; be angularly tilted upon shaft 17 to either side, as is indicated in dotted lines in Fig. 3.
When in its tilted position table 21 has been brought to a desired degree of inclination, screw 23 is then turned for causing the same to engage and bear against shaft 17 for locking table 21 in its inclined adjusted position to shaft 17. As was hereinabove mentioned calibrations 28 in conjunction with pointer 29 will indicate the degree of incline of table 21 from horizontal.
Centrally table 21 is provided with bore 38 and with a plurality of radial slots 39. Through said bore 38 a reciprocating saw may be passed, while through one of said slots 39 a sutiable support may be extended to bear against and press upon the work supported upon the table for advancing the Work against the saw.
For all intents and purposes said sleeve 22 may be considered as a part of bearing 18 which carries it. If desired said sleeve may be eliminated and screw 23 may be passed through one or both bearings 18 for the purpose of engaging shaft 17 for locking table 21 in its adjusted tilted position when said shaft has been shifted away and disengaged from said wing 35.
While there is described herein preferred embodiments of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
