.specification of Letters Patent Patent-ed Sept- 1., 191s Application filed pecernber13, 191Q. Serial No. 597,013.
This invention relatesto laps and consists ,in eertainirnpro'veinents in the construction .thereof as will be hereinafterl fully de-l scribed and pointed out iu the claims. I 'f More particularly, the invention relates to e type 0f lap' espally adapted for nishns the interiorv surfaeesof tubes of considerable length, such gas, working'barrels in Artesian well pumps.
` The invention is illustrated in the aecompanying Vdrawings as follows:
Figure llsho'ws a plan View of the lap. Fig.
z2 asection-on the lines 2-*2 in Figs. l., 3, 4
.and 5. Fig. 3 a section on the lines 3 3 in 1 .and 2. 4 a section'on the lines in' Figs. 1 and Q.A Fig. 5 a section on .the linesES--l in Figs. 1 andA 2.
1 marks the lap wheel.` This is formed of some :soft material, and is divided longitu dn'ally. Bars Q-2 extend through the wheel, these barsbeing cast in the wheel' parts. Thebarsat one end are separated by the block 3, and have'theclarnping blocks 4 and 5 opposite the block 3, the blocl 4 being perforated and the; xblock 5y screw threaded, and the whole Vclamped .together by a screw 6.4 The blocks 3, 4 yand 5 with the bars are ,preferablyeircular outline in end view.'V The opposite end of the bars 2 are separated f by the block 7 which extends from the drivinghead 8. Blocks 9 and `1() are/arranged opposite the block 7, the block 9 being per; forated and the block/ 10 perforated andl screw threaded, andthe parts clamped together with the screw 11. With this arrangement of bars,.it will be observed that both ends of the lap wheel are similarly' restrained, land `have an equal tendency for outward movement so that as the lap wheel is inserted in the barrel or tube that hasbeen ground,there Is no tendency for one end of the wheel to exertA greater pressure, and con sequently have greater grinding effect than the opposite end. This is of great advantage in. that it ,assures a more even surface than where the ends are not balanced.,
The wheel is driven from the'head 8 `with any desired source of power, and so arranged that the lap wheel may be passed depended upon.
' through the tube' if desired. The bars have vthe perforations 12 into which the metal Iiews as at 13, thus locking the bars against endwise movement in the wheel parts. Ihese wheels are sometimes used by rotating the work instead :of the wheel.A Where this is done, it is desirable to have some means for forcing the wheel p'arts outwardly.` This rnay bevacconiplished by` a spring action on the bars Q, but 'I prefer to accomplish/y it by meansv of `supplemental springs. The opposing faces of the wheel parts have the sockets 14 preferably extending to a depth of the face of the bars, andin these sockets are placed coil springs 15Y desired, thus giving any predetermined size.
to the lap wheel that may be de'sixied.y x. f
I prefer to reinforce the bars .adiaept .150
the perforation 16 by `means ofthe plateslli);
which extend into the :ends of the wheel parts, and 'areseoured to the ebars 2 by ,ineens of the rivets 20. These plates so reinforce the bars at this point that `there -is ilittle 'give "Ito ltheniuso 'that the voutward l'irnit of'thev wheel parts will not be influenced to any great extent by any change of speed ofthe wheel, or other conditions which might `in terfere with accuracy, if the bars only were In order to effect a more uniform distributlon of the grinding material which is ordinarily emery and some 'liquid carrier, I
prefer to provide the faces of the wheely arts with the grooves 21. These grooves korm screw threads which yas the Wheel advances pick up the grinding material from the surface ofthe tube or barrel, and carry it along the Wheel surface so as to distribute v it. These grooves arepitched in both directions so that they will operate in either direction as the feed is reversed.
` lWhat I claim as new is:
l. In a lap, the combination of a lap wheel divided longitudinally; axially ex tending spring bar supports for the wheel parts; a rotatable mounting'for lsaid sup-' ports having its axis onthe axis of the lap Wheel; and means for limiting tlie outward movement of the parts.
2.72111` a) lap,`-the combinationof alap Wheel divided longitudinally; spring bar supports extending axially from both ends of the wheel parts; andvmeans uniting the bars at each 'end of the Wheel-parts.
3. In a lap, the combination of a lap Wheel divided longitudinally; bar supports extending axially from both ends of the Wheel parts.; means uniting the bars at eachv end of the wheel parts; and devices for limiting the outward movement of the parts.
.-1. In a lap, the combination of a lap -wheel divided longitudinally; bar sup or'ts extending axially from both ends o the wheel parts; means uniting the bars at each end of the wheel parts; devices for limiting the outward movement of the parts; and means for adjusting said devices to vary the vlimit of outward movement of the parts.
5. In a lap, the combination of a lap wheel divided longitudinally, the opposing faces of the parts having spring sockets therein; axially extending bar supports for the wheel. parts; a rotatable mounting for said supports havingnits axis on the axis of the lap Wheel; and a spring in said sockets for forcing said parts outwardly.
6. In a lap, the combination of a lap wheel divided longitudinally, and having sockets in the opposing faces of the parts; bar supports extending axially from both ends of the Wheel parts; means uniting the bars at each end'of the Wheel parts; and springs in said sockets tending to force the said parts outwardly.
7. In la lap, the combination of a lap Wheel divided longitudinally; axially extending supporting bars for the-wheel parts; remforcing plates extending from the ends of the Wheel parts; adjustablemeans forl limiting the outward movement of the wheel parts acting on the portions of said bars reinforced by said plates.
8. In a la thecombination of 'a lap wheel divided) longitudinally; bar sup orts extending axially from both ends o the wheel parts; means uniting the bars-at each end of the Wheel parts; yreinforcing plates extending from the ends of the wheel parts on said bars; and adjustable means for limiting the outward movement of the wheel parts and acting on the portions of said bars reinforced by said plates., ,i
9. In a lap, the combination kof a lap Wheel divided longitudinally; and supports for the lap wheel, there being a spiral groove on the surface of the lap wheel.
,10. In a lap, the combination of va lap Wheel divided longitudinally; and supports for the lap wheel, there being spiral grooves pitched in both'directions on the surface of said lap wheel.
11. In a lap, the combination of a-lap wheel divided into segments; supports for said segments permitting the radial movement of the segments ;and adjustable means limiting the outward movement of the segments; a rotatable mounting for said supports arranged with its axis on the axis of the wheel4 to a predetermined outer working position.
