Application filed January@ To all who/m,` it may concern Be it known that I, Louis HARRIS, a citizen of the United States, residing at .Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements iii-'Surfacing Apparatus, of which the following is a specification.

My invention relates yto improvements in surfacing apparatus for plane or flat, preferablylwooden surfaces, and has especialreference to apparatus of this character for planing .andiscraping the surfaces of bowlingalleys.

' rOne of the objects provideanapparatus, consisting of a. series or gang of overlapping planes removably secured in a suitable slab or frame block, movable longitudinally of the alle over the surfaces of such structures in paths substantially parallel with the grain of the boards or wood of which the-alley is composed, whereby ,to prevent transversely extending kerfs, tool marks, or scratches to divert. the path of the ball as when the usual rotary planer and sander is used for the purpose.

yAnother lobject ofmy invention is to simplify and cheapen the driving and guiding means for the planes without requiring a special track to be laid upon which to move the surfacing apparatus.

Other ,and further ohj ects of my invention will become readily apparent to persons skilled in the art, from a consideration of thef following description when taken in conjunction with they drawings, wherein `Figure V1 is a' broken away plan view of a bowling ,alley showing my apparatus as applied thereto. c

block or slab of `cast iron, or the like, with aplurality or group cfapertnres ateach en to receive removable .planes arranged in interlapped rrelation `and so positioned that when the block is being A,pulledor driven in one, direction, oneV series or set of planes will be operatively active, the other series having been previo uslv automatically raised kso that their .bits will not .touch the surface over whichtheyare passing,y and when the block is being-.moved intheopposite direction-the formerly .idle series are-depressed so as to make engagement with the underlying surface of the alley ^while the before-mentioned ,active series are raise'dfrom the surface over which the block isto be,` passed. It further consists in especial and improved means for dragging the block over the surface Ato be planediand other details of construction to be hereafter morejfully explained.

10 isablock, preferably of cast iron, or similar material, containing two rows of perforations,11 and'1Z, at each end, within which to containplanes 13 or scrapers 14. The perforationsll and 12 are so arranged, as will be observed, vthat the bits of the planes .willoverlap sothat the planes kwill jointly operateas if the cutting orplaning were being done with a single' blade. Each ,of theperforations, 11 and V12,'i's provided with a shoulder 111, at one end, undercut, as at 15, under which to receive a similar shoulder 16 projectingforwardly from the plane or scraper to prevent that end. of the plane from rising above the plane block. 'The lower surface 17 of the planes is designed tobe in linewith thelower surface 18 of the plane block. `"Iheplane block is also provided with ,another shoulder 19, somewhat longer than the shoulderl, havingpa depression in its'face wherein to. receive an openhelical spring 20 which is adaptedtolift the end of the plane upon which the shoulder 19. isr contained. when the latch 21 is removed from its path.v In other respects the plane. 13 and the scraper 14: are ofthe usual conventional form, each having

abit

22 and 23, respectively, secured by a thumb 'nut'v 24 and a pivoted lever 25 as usual in 4such structures, and where I have used ktheyterm plane in theclaims, it is inftendedgto befsuiciently comprehensive to include` the interchangeable Scrapers.

l lNear ,the center of the plane block 10 isa rcablet,1gui ding sheave 23, mounted upon the Vstandard 9A, one on each side. These sheaves i astenings.

. shaft slk end lot the block being a6 are moved, aXially,

Qi ina-saca are to guide the ropes or cables used to pull the plane block across the surface to be pla-ned. Near each end of the plane block, and on either side thereof, are eye bolts 25 to which to secure the ends of the cables. `In substantially the center of the plane block 10 is a seat for accommodation of the operator Who may ride upon When additional Weight is necessary to hold it to the underlyring` surface to be planed.

An electric motor 27 is mounted upon the guide track 28. rl'he track is held in place, at oneend of the alley 29, by means of the springs SO-SO or other'preferably yielding These springs give tension to the cables 8l and 32 and hold them in close contact with the driving sheaves 40. Gn the motor shaijt 33 is a small pinion 34 geared into a larger gear Wheel 35. The gear Wheel 35 is secured to a transverse shaft 36 which has bearings in a frame 37 as at 38 and 39. @n the outer ends of the shaft 36 are sheaves 40%() for the cables 3l and 32, respectively, At the other end of the alley 29, is a similar all, fhaving bearings in standards 42-2 that are secured to a longitudinally adjustable structure or base plate 43. rThe standards 42-4l2 are separated so that the sheaves Het on the shaft 4l, are the same distance apartas the sheaves 40%0 on the shaft 8G. The base plate 43 is slidable in a guiding casting or trackway t5 in a direction transversely of the alley 29. The casting l5 may be secured in place in any desirable manner, as by block and fall or by bolts or the like. The springs 30-30serve to put sufficient tension on the cables 31, 32 and theY sheaves 40-10 to produce the required traction to move the plane block l0 over the alley Way.

rlhe rotation of the armature of the inotor 27 will cause the sheaves 40-40 to move the cables 3l and 32 in either direction, t0- Ward the motor or from it, and thereby to move the plane block 10 in corresponding directions. When the block is being moved toward the right hand side, the planes `on the lett end of the plane block l0 arein operative condition, the planes on the other lifted from Contact with the-underlying surface to beV planed.

The latches 2l which hold the planes and scrapers doivn to their Work are connected together by rods 4:6 so that When the rods all of the latches 2l of a series are moved in a given direction, either to hold the planes in their positions or to release them, whereupon `the springs 2O will littthem so that the blades ot the lifted planes will not be in contact With the underlying surface of the alley. rlhe rods tifare connectedat one end to the bell cranks 18 and 49, respectively, and these bell cranks are connected together by links 50, the arrangement being such that When the link the plane block one directionuone set moved v1n position to permitthe springs 20 to raise the planes 'or Scrapers, as shoivn on ot Fig.V 3, and when the right hand side they are moved in the opposite direction the latches 2l are moved to such positions as to depress the planes or Scrapers against the resistance of the springs 2O to holdthem in operative positions as shown in Figs. d, 5 and 6.

Now when the plane block vl0 is moving to the right, as shown by the arrow in Fig. 3, the set ot' the planes or scrapers on the left end of the block are depressed into operative position While the planes or Scrapers on the other end of the bloclrare raised out of contact with the underlying surface.

l/Vhen the block has been moved the `full extent of the alley and the motor is reversed so as to move the block in the opposite di'- rection, then the hand wheel 52 is rst turned so as to cause the latches 2l to Vrelease the planes on the left end and depress those on the right end, so that when the block l() is being` moved to the left thev planes on the right or trailingrend are at Worlt. v Y lifter the block yl0 has been pulled over the alley, beginning atoneside thereof, the motor 27 may be moved laterally so that the bloclt will move over to the new path and thus the motor and the counter shaft l may be moved in the respective guide Ways 2S and 45, until the entire alley has been lthus planed. After the planing operation has been completed the planes 18 are replaced by the Scrapers lll and the operation is substantiallyV repeated. 1 Y ,i Y

l have not shown the electric circuits for the motor nor the means for reversing it,

as such means do not constitute any part of my invention. Y v

Having described my invention, What l claim is 2- Y l. In a device of the character described the combination of spaced-apart parallel guide tracks, or Ways to be placed at opposite ends of a surface to be planed; a structure, one for each Way, carrying spaced-apart sheaves and longitudinally adjustable on said Ways; a motor, for driving one pair of sheaves, movable with the respective structure, a block, carrying a plurality of planes, movable betvveensaid Ways and a pair of chains, or cables overlying appropria-te sheaves on said structures and having their opposite ends connected to opposite ends of said plane block.

Q. ln a. devlce ci' the character described the combination of spaced-apart parallel sheaves on said structures and having their opposite ends connected to opposite ends of said plane block and springs connected to one structure to increase rictional contact between the driving sheaves and the respective chains or cables.

In testimony whereof l hereunto set my hand in the presence of two subscribing Witnesses.
