To all whom it may concern.-
Be it known that 1, CHARLES S. YARNELL, of Minneapolis, in the county of Hcnnepin and State of Minnesota, have invented a new and useful Improvement in Abrading or Polishing Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.
This invention relates to improvements in anabrading or polishing machine of the general character of the machine shown in Patent No. 507,251, issued to me October 24, 1893, and more specifically in application Serial No. 731,402, filed by me September 22, 1899. The machine includes a carriage on which the abrading or polishing device is mounted, conveniently designated the polisher-carriage, which carriage is reciprocable on a guide-bar disposed horizontally, which guide-bar is pivoted and swiveled on a standard or suitable support, so as to be capable of being tilted vertically and of being swung laterally limitedly. The matter is supported on a flattopped table, and the abrading or polishing device, traveling on the guide-bar, is moved forward and backward over the surface of the material.
My present invention has for its object the providing of means for conveniently raising and lowering the pivoted support of the guidebar, on which bar the abrading or polishing carriage reciprocates, thereby providing for raising or lowering the guide-bar itself to adapt it for use with material of different thicknesses on a table having a fixed or permanent top, thus obviating the need for adjusting the material-holding table-top up or down and also providing means for adjustably limiting the lateral swing of the same guide-bar.
In the drawings, Figure 1 is a view of the standard or post and the polisher-carriage guide-bar of an abrading or polishing machine with my improved means for raising and lowering the guidebar and limiting its lateral swing. Also a material-holding table top is indicated to show the relation of the polisher-carriage thereto. Fig. 2 is a top plan view of the fragment of the standard shown in Fig. 1 with my improved devices in longitudinal groove 10 therein.
connection therewith and with a fragment of the guide-bar. Fig. .3 is an elevation of my invention in connection with a fragment of the standard and the guide-bar in section, showing the relation of my improved devices thereto, parts of the construction being shown in section. Fig. 4 is an enlarged view of a detail of the construction shown in Fig. 3, parts being in section for convenience of illustration.
In the drawings, 5 is a fragment of a standard or portion of the frame of an abrading or polishing machine. The standard is preferably in tubular form.
6 is the guide-bar on which the polishercarriage 7 reciprocates.
8 is the top of a table on which the material A is placed for being abraded or polished.
' A smooth cylindrical bearing on the standard 5 is conveniently formed by fixing a sleevebearing9 thereon. The exterior surface of this sleeve-bearing is smooth and preferably cylindrical, the sleeve being provided with a A split band 11 about the standard 5 and clamped thereto by bolts provides a convenient means for holding the sleeve 9 securely against moving down on the standard 5, and also this band 11 being provided with a ledge or lateral extension 12, which may also be a part of the general frame of the machine, forms a footing for a screw 13, which screw at its upper extremity has a bearing revolubly in a lug 14,-fixed on the sleeve 9. A collar 15, fitted and adjustable vertically on and about the sleeve 9, is provided with a loose key 16, that fits in a groove in the inner surface of the collar and in the groove 10 of the sleeve 9, and a set-screw 17, turning through the collar against the key, is adapted to clamp the collar in position releasably on the sleeve 9. This construction prevents rotary movement of the collar 15 on the sleeve 9, but permits it to be adjusted vertically. The screw 13 passesthrough a nut 18, fixed on the collar 15, whereby by the rotation of the screw 13 the collar 15 is moved up or down.
The guide-bar 6 is swiveled and thereby supported tiltable vertically on the collar 15 conveniently by means of a ring 19, which is provided with a hub 20, that rests on a ledge leasably to the ledge.
guide-bar.
21, projecting laterally from the collar 15, the ring 19 being also provided with a pintle 22, that passes through the ledge 21 and is provided with a nut securing it lnovably and re- The guide-bar 6 is pivoted tiltable vertically in the swiveled ring 19 by means of opposite horizontally-disposed pivot-pins at 23, turning through the sides of the ring into sockets therefor in the A short crank-shaft 24, provided with a terminal beveled wheel that gears with a beveled wheel 25 on the screw 13, provides a convenient means for rotating the screw by means of a crank-handle to be placed on the faced end of the shaft.
passing through longitudinal slots therefor in 0 the sleeve 9 into the shaft 5, may be employed to hold the sleeve against movement on the standard.
What I claim as my invention is- 1. In an abrading-machine,the combination with a horizontally-disposed carriage guidebar, of a standard, a non-revoluble collar fitted movable vertically on the standard, and supporting the guide-bar, a nut fixed on the collar and projecting laterally therefrom and a screw alongside of and parallel with the standard turning through said nut, the screw being supported revolubly but against endwise movement and being adapted to raise and lower said collar alongside on the standard.
2. The combination in an abrading-machine, of a standard, a collar movable on the standard, a screw turning through a nut on the collar and adapted to adjust the collar on the standard, a ledge on the collar, a ring swiveled on the ledge, and a carriage guidebar pivoted in the ring.
3. The combination in an abrading machine, of a standard, a bearing on the standard provided with a longitudinal slot, a collar fitted on the bearing and provided with a key fitted loosely in the slot in the bearing, a screw turning in the collar against the key, a carriage guide-bar supported on the collar, and means for moving the collar adj ustably on the bearing.
4. The combination in an abrading machine, of a guide-bar provided with a swiveling support permitting lateral swing of the guide bar, and adjustable stops near the guide-bar one at each side of its swiveling support, the stops being adjustable toward and from the guide-bar and adapted to limit its lateral swing.
- 5. In anabrading-machine,thecombination of a standard, a collar adjustable vertically on the standard, a carriage guide-bar swiveled on the collar so as to have lateral swing thereon, arms projecting from the collar substantially parallel with the guide-bar, and stops on the arms secured thereto adjustable toward and from the guide-bar, the stops being severally on different sides of the swiveling support of the bar.
In testimony whereof I afiix my signature in presence of two witnesses.
CHARLES S. YARNELL.
