CHARLES F. 'HALDEMAN, 0F SALEM, OHIO, ASSIGNOB- TO THE SILVER MANUFACTURING COMPANY, OF SALEM, OHIO, A CORPORATION OF OHIO.

ADJUSTABLE TABLE FOR J OINTERS.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed June 1, 1908. Serial No. 436,154.

To all whom it may concern:

Be it known that I, CHARLES F. HALDE- MAN, a citizen of the United States, residing at Salem, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Adjustable Tables for J ointers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, and to the numerals of reference marked thereon, in which- Figure 1 is a vertical longitudinal section taken on line 11, Fig. 5. Fig. 2 is a perspective view. Fig. 3 is adetached View of the brackets, hand wheels and shaft designed to vertically adjust one of the adjustable tables. Fig. 4 is a similar view showing the parts properly connected to one of the tables showing said table in section. Fig. 5 is a transverse section taken on line 5-5, Fig. 1. Fig. 6 is a detached View of one of the longitudinal table adjusting shafts showing the different parts designed to be connected thereto. Fig. 7 is an enlarged transverse section of one of the table bases showing the shaft and gear wheel designed to actuate the table in proper relationship with reference to said table base.

The present invention has relation to adjust-able tables for j ointers and it consists in the parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawing, 1 represents the base or standard which is of the usual construction but forms no particular part of the present invention, so far as its detailed construction is concerned. In the brackets 2 is journaled the shaft 3 upon which shaft the jointer head .t is mounted and to which are attached the knives 5. This construction is common and forms no specific part of the present invention. The base 1 is provided with the ribs or guide flanges 6, which guide flanges are for the purpose of holding the table bases 7 by means of the flanges 8 and 9, which flanges are so arranged that they will come under the guide fiangesti as best illustrated in Figs. 5 and 7.

For the purpose of adjusting the frictional contact as between the guide flanges 6 and the flanges 8 and 9, the flanges 9 are adjustably connected to the table bases 7 by means of the usual clamping bolts 10, which flanges are held by means of the clamping bolts 10 and also by the set screws 11. To each of the table bases 7 are connected the rack bars 12, by means of the connecting bolts 13 or their equivalents. Directly below the rack bars 12 are located the pinions 1a, which pinions mesh with the rack bars 12 and are for the purpose of imparting reciprocating mot-ion to the table bases 7, which table bases slide upon the top of the base or standard 1, this particular feature being best illustrated in Figs. 5 and 7. The pinions 14 are securely mounted upon the shafts 15, which shafts are carried by the standard 1, and one end of each shaft is journaled in one side of the standard and the opposite ends are located through the hollow and internal screw threaded clutch members 16. The shafts 15 are each screw threaded for a portion of their lengths and the screw threaded members located upon the screw threaded portions of the shafts for the purpose hereinafter described. Upon each of the shafts 15 is mounted a hand wheel 17, which hand wheels are provided with suitable hubs, one end of each hub constituting a clutch member 18 and the opposite end of each hub is provided with the recess 19, the clutch members 18 and the recessed ends of the hubs proper are for the purpose hereinafter described. The hand ,wheels 17 are slidably mounted upon the shafts 15 and when it is desired to rotate the shafts 15 the hand wheels 17 are moved outward and away from the standard 1, until the pins 20 are brought into engagement with the recesses 19 and when the pins 20 are in engagement as above pointed out the shafts 15 can be rotated by means of the hand wheel 17, which rotation imparts rotary movement to the pinions 14-, the pinions being securely mounted upon the shafts 15 by means of the pins 21., and the recesses 22. However it is immaterial as to just how the pinions lt are securely connected to the shafts 15. It will be understood that when the pinions 1 1 are rotated the table bases 7 together with the different parts carried thereby will be moved to or from the jointer flange is for the purpose of coming in contact with the outer face of the standard, 1, as best illustrated in Figs. 5 and 7. The ends of the shafts journaled in the opposite side of the standard 1 are each provided with the disks 2 1, which disks are held upon the shafts 15 by means of the cotters 25 or their equivalents.

After the table bases 7 have been brought into the desired adjustment the hand wheels 17 are moved upon the shaft 15, until the clutch ends of the hubs of the hand wheel 17 are brought into engagement with the clutch members 16, at which time the clutch members 16 are rotated with the rotation of the hand wheels 17, and when rotated in one direction the flanges 23 and the disks 24 will be brought into snug contact with the outer side faces of the standard, 1, thereby frictionally holding the shafts 15 against rotation, but when it is desired to rotate the shafts 15 with the hand wheels 17, said hand wheels are rotated in the opposite direction until after the shafts 15 have been released so as to rotate freely and the hand .wheel 17 brought into engagement with the pins 20, thereby rotatably connecting the hand wheels with the shafts 15, after which the table bases can be adjusted to any desired position within the limits of their movements.

Directly above the table bases 7 are located the tables 26, said tables being located upon opposite sides of the jointer head 4;.

For the purposes of supporting the tables 26.

the table bases are provided with the carrying brackets 27 and 28, which brackets are securely attached to the table bases in any convenient and well known manner. The tables 26 are provided with the downward extending brackets or flanges 29 and 30, which brackets are provided with apertures through which apertures the inclined bars 31 pass. To the table bases 7 are connected the bearing brackets 32 through which bearing brackets are located the vertically adjusting screw threaded shafts 33, which screw threaded shafts are extended through the screw threaded apertures 34 formed in the downward extended arms 35, which arms are divided at their lower ends and are so divided for the purpose of adjusting the frictional contact or engagement as between the screw threaded shafts 33 and the screw threaded apertures 34- by means of the screws 36. It will be understood that by this arrangement the adjustment can be such that there can be no loose movement: as between the arms 35 and the screw threaded shafts 33. The screw threaded shafts 33 are each provided with non-screw thread ed portions 37, which non-screw threaded portions are located in the bearings 32 as best illustrated in Fig. 1. Upon the shafts 33 are securely attached the hand wheels 38 and upon the outer screw threaded ends of the shafts 33 are located the hollow internal screw threaded knobs 39, which knobs are for the purpose hereinafter described.

It is well understood that in jointers of this kind and class it is necessary to change from time to time the depth of cut of the knives secured to the jointer head and in order to provide for this adjustment of the cut of the jointer knives it is necessary to elevate and lower the tables 26 so that the extreme upper movement of the knives of the jointer head will come a given distance above the tables 26. It will also be understood that after the tables 26 have been brought into the desired adjustment for the particular work to be performed it is necessary and'of importance to hold the tables 26 in rigid condition. When it is desired to change the adjustment of the tables 26 with reference to the jointer head and knives the proper hand wheels 38 are rotated in the desired direction and when rotated in one direction the table or tables 26 will. be elevated by reason of the movement of the arms 35 upon the screw threads of the screw threaded shaft 33, and by reason of the flanges or brackets 29 and 30 moving upon the inclined bars 28, the table will be elevated or lowered.

It will be understood that the bars 28 must be inclined parallel with the inclination of the screw threaded shafts It will be understood that each end of each table 26 must be supported and in order to so support the tables 26 the inclined bars 31 are secured to the brackets 26 and 28. It will be understood that after the tables 26 have been brought into the desired adjustment it is of importance that said adjustment remain fixed so that there can be no accidental or unintentional vertical movement of the tables 26, except when a predetermined adjustment is desired.

For the purpose of locking the tables 26 in fixed adjustment the knobs 39 are provided. and when the knobs are rotated in the direction to carry said knobs toward the hand wheels 38. The collars 40 which are securely fastened to the shafts 33 will be brought into close contact with the ends of bearings 32 thereby frictionally holding the inclined shafts 33 against rotation. It will however be understood that there must be a very slight end movement of i the screw threaded shafts 33 at the time the knobs 39 are rotated so that there will be a slight pushing of the hand wheel 38 and a slight pulling of the shaft 33 whereby the collars 40 and the hubs 41 of the hand wheels 38 will be brought into snug contact with the ends of the bearings 32. In order to allow for this slight end movement of the shafts 33 said shafts are provided with the slots a2 through which slots the pins as are passed said pins being securely connected to the hubs ll. of the wheels 38.

It will be understood that provision must be made for the proper gage to hold the work in proper position upon the tables 26, and in order to provide for the proper holding of the material the gage 4:3 is provided which is held in place by means of the slotted bar 44 and the setting bolt a5. These parts, however, so far as the gage is concerned form no specific part of the present invention and are of the ordinary construction. It will be understood that by providing means for moving the table bases 7 longitudinally together with the different parts carried by said table bases they can be moved considerable distance from the jointer head thereby providing suflicient room to adjust the knives to the planer head and to remove one set of knives and substitute another set.

In jointers of this class itis'of importance to provide means of easy access so that changes can be easily and quickly made from time to time. Then the tables are brought into the position for actual use the inner ends of the tables 26 should be brought into close proximity with the jointer head and knives, said adjustment being such that there will be no contact of the knives with the tables.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is-

1. In an adjustable table for jointers, a base, table bases slidably mounted upon said base, rack bars connected to and carried by said table bases, shafts provided with screw threaded portions, combined shaft bearing and clutch members journaled in the base, said combined bearing and clutch members mounted upon screw threaded portions of the shafts and wheels slidably mounted upon the shafts and provided with clutch members adapted for engagement with the clutch members journaled in the base, pinions mounted upon the shafts, said pinions adapted to mesh with the rack-bars carried by the table bases and means for holding the shafts against rotation and locking the table bases infixed adjustment, substantially as and for the purpose specified.

2. In an adjustable table for jointers, a base, table bases slidably mounted upon said base, rack bars connected to and carried by said table bases, shafts provided with screw threaded portions, combined shaft bearing and clutch members ournaled in the base, said combined bearing and clutch members mounted upon screw threaded portions of the shafts and wheels slidably mounted upon the shafts and provided with clutch members adapted for engagement with the clutch members journaled in the base, pinions mounted upon the shafts, said pinions adapted to mesh with the rack-bars carried by the table bases, and means for holding the shafts against rotation and locking the table bases in fixed adjustment and tables carried by said table bases, substantially as and for the purpose specified.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.

CHARLES F. HALDEMAN.
