MACHINE FOR DRILLING TIRES AND FELLIES OF WHEELS.

SPECIFICATION forming part of Letters Patent No. 576,305, dated February 2, 1897.

Application filed January 28, 1896. Serial No. 577,109. (No model.)

To all whom it may concern.

Be it known that we, ELBRIDGE S. FELTGH and CHARLES E. STONE, citizens of the United States and residents of Ainesbury, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Drilling the Tires and Follies of Wheels, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to drilling-inachines, and particularly to that class thereof which are designed for use in boring the tires and fellies of wheels and countersinking the bores in the tire; and the object thereof is to provide a machine of this class which is so constructed and arranged that the wheel after having been placed upon the machine is retained thereon until the entire operation is completed, said Wheel being revolubl y supported and being turned on its support until the entire tire and the fellies are suitably bored; and with this and other objects in View the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

It is necessary to employ different drills in boring the tires, the follies, and countersinking the bores in the tires of wheels, and at least three different drills are required, and in most machines of this class it is necessary to take the wheel from the machine while changing the drills, but in our improvement this difficulty is avoided, and we employ a revoluble tripod, which may be provided with any desired number of drill-heads, and these different drill-heads are adapted to carry the different drills required.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a side elevation of our improved drilling-machine; Fig. 2, a plan view thereof; Fig. 3, a side elevation of one form of tripod which we employ, showing one drill-head connected therewith; Fig. 4:, an end view thereof, showing three drill-heads Fig. 5, a section on the line 5 5, lookingin the direction of the arrow a; Fig. 6, an end view of a plate provided with a central tubular extension by means of which the tripod and the tripodspindle are connected with the frame of the machine. Fig. 7 is a plan view of a modified form of turret, showing two drill-heads connected therewith; Fig. 8, a section on theline 8 8 of Fig. 7, and Fig. 9 is a side elevation of a sleeve which forms a detail of the construction shown in Fig. 7.

In the practice of our invention we employ a frame comprising end standards A and A which are united at the top by horizontal side bars A and A, and thohorizontal side bars A and A" are firmly connected by cross-bars or plates a, a and (t and this frame is composed, preferably, of wood, and is also made strong and substantial, but the exact form thereof is immaterial, as is also the method of its construction.

.Pvassin g centrally and longitudinally through the lower portion of the frame is a shaft 13, which is provided with three pulleywheels B B and 13*, which are of different sizes and increase insize in the order named, and on the outer end of said shaft is a powerwheel B to which in practice apower-belt is applied.

Secured to the cross pieces or bars a and a in the top of the frame, and on the upper sides thereof, are housings C and 0 through. which the driving shaft or spindle D passes, and mounted on said driving shaft or spindle D are pulley-wheels D ,D ,and D which decrease in size in the order named, and said pulleywhcels are designed to be operated bybelts E and E, which are mounted on the wheels D and D* and also on the wheels 13 and B on the shaft B, and it will be understood that either one of these belts may serve to operate the driving shaft or spindle D, and that two orthree thereof may be employed, if required.

The driving shaft or spindle D is movably mounted in the housings O and O and is adapted to be moved longitudinally therein, and in this operation it passes through said housings in the usual manner, and the pulleywheels D D and D are also connected therewith as usual in this class of devices, and these elements of construction are all substantially the same as those heretofore employed in this class of machines and form no part of our present invention. In order to operate this shaft, we connect with the outer end thereof a lever F, and this lever is connected with the shaft by a collar F in the usual manner, said collar being held in place by rings or bands F one of which is mounted at each side thereof, and said lever is connected at one end with the frame, as shown at F and the handle thereof extends across the bar F which is also connected with the frame and on which the handle end of said lever is free to slide.

The inner end of the driving shaft or spindle D is provided with a head d, in the outer end of which is formed a central cavity or recess d (shown in dotted lines in Figs. 3 and 7,) and which is adapted to receive the end of a drillspindle, and at each side thereof is formed a cavity or recess (1?, also shown in dotted lines in said figures, which are adapted to receive pins or projections secured to the drill-spindle, which is mounted in the drill-heads, as hereinafter described.

\Ve also employ a turret, which consists of a head G, which is shown in Figs. 3, 4, and 5, and which, as shown in the drawings, is provided with a number of drill-heads G but one of which is shown in Fig. 3 and three of which are shown in Fig. 4, and this turret is adapted to be connected with a turret-spindle g by means of a rivet g as shown in Fig. 3, and said turret-spin dle is passed through a sleeve which is formed on a plate 9, which is bolted to the cross-bar a of the frame, as shown in Fig. 1, and the end of the turretspindle 9 extends through said cross-bar a of the frame and is provided with a circular head, ring, or band g, between which and the plate g or cross-bar a is mounted a strong spiral spring g, and secured in the outer end of the sleeve g" is a pin (shown in dotted lines in Fig. 3,) which is adapted to project into a cavity or recess formed in. the adjacent end of the head G, and also shown in dotted lines in said figure.

Each of the drill-heads G consists of a band H, through which passes a drill-spindle 72, (shown in dotted lines in Figs. 3 and 7,) the outer end of which is provided with a head 7L2, which is provided centrally with a hole or opening 72 into which the drill or tool is adapted to be inserted and wherein it may be fastened by means of a set-screw h, and the inner end of the spindle 7t is provided with a collar or band h, which is secured thereto in any desired manner and which is provided with pins or projections h, which are adapted to enter the holes or openings d in the head (Z of the driving shaft or spindle D, and formed on the end of the drill h is a conical projection 7L7, which is adapted to enter the conical cavity or recess (1 which is also formed in the head (Z of the drive shaft or spindle D. It will be understood that by means of this construction the drill-spindle h is free to revolve in the tubular head or sleeve II and that any number of these tubular heads or sleeves may be employed, three thereof being shown in Fig. 4, and in Fig. 2 we have shown an ordinary drilling-tool H connected with one of these drill-spindles and a reamingtool H connected with another.

Ve also provide a wheel-cup K, which is mounted at the forward end of the frame of the machine and is capable of vertical ad justment by means of a screw or screws K (shown in Fig. 1,) and this wheel-cup is also capable of longitudinal adjustment on the supports thereof, which are shown in dotted lines at K in saidfigure, and secured to the upper portion of the frame of the machine and to the side bars A and A thereof are verticallyadjustable spring-supports 71:,which are adapted to support the tire of a wheel and which are vertically adjustable by means of screws k one of which is shown in Fig. 1, and secured longitudinally and centrally of the frame between said supports is a sliding plate L, the end of which is provided with a metal block L which is connected therewith by means of a tongue-and-groove or dovetailed coupling, as shown at L and the outer sur face of this block is slightly curved or segmental in form, so as to correspond with the form of a felly of a wheel, and these blocks L are preferably just the length of the fellyplates between the holes, and by placing the joint of the felly at one end of a block and drilling one hole and then placing the joint at the other end of the block and drilling the other hole these holes will come exactly right for the felly-plates and without marking the same.

Secured to the side bar A of the frame and to the upper surface thereof is a plate-spring M, which is adapted to project over the tire and felly of a wheel' when the the latter is in position, as shown in Fig. 2, and pivotally connected with said spring is a rod m, the lower end of which is connected with a footpedal m as shown in Fig. 1, and the operation of this form of construction will be readily understood from the foregoing description, when taken in connection with the accompan yin g drawings and the following statement thereof.

It will be understood that the turret-spindle g is adapted to slide in the plate g and the sleeve 9 which is formed thereon, and the turret-head G is rigidly connected with the outer end of the turret-spindle, and in order to drill the holes for the tire-bolts the hub of the wheel is placed in the wheel-cup, as shown in Fig. 2, and the tire and felly on the hearings or supports 70, and the spring M is then forced down by means of the pedal m onto the tire, and by this operation the wheel is firmly held in position. In order to drill a tire, the turret-head G is turned until the drill-head II, provided with the required drill or tool, is opposite the driving-spindle D. The said driving-spindle is then brought forward by means of the lever F, in which operation it connects with the drill-spindle h, as hereinbefore described, and in order to ICS countersink thc drill-holes in the tire to provide room for the heads of the bolts the drivespindle is moved backward and the turrethead turned so as to bring the drill head or spindle provided with the reaming-drill into line with said driving-spindle, and the operation above described is repeated, and after the bore in the tire has been countersunk the turret-head is again turned so as to bring the spindle provided with the drill which is designed for use in boring fellies into line with the driving-spindle.

It will thus be seen that the tire may be bored and the bores thereof countersunk and the fellies bored without moving the wheel from the machine, all that is necessary being to revolve the turret-head so as to bring the drill-spindle provided with the necessary tools into line with the driving-spindle D, and all that is necessary in order to bore the tire and the fellies and to countersink the bores of the tire, as above described, throughout the entire circumference of the wheel is to simply revolve the wheel in the wheel-cup and to operate the turret-head and the driving-spindle as above described, and this operation can be performed as rapidly and expeditiously as desired. lVhen the lever F is operated in this manner, the driving spindle slides through the pulleys D D and D and the housings O and (l and the clutching device on the end of the driving-spindle, which consists of the head 61, provided with the holes or openings d and d engage with the corre sponding devices on the end of the drill-spindle h, as hereinafter described, and said drillspindle turns easily with the sleeve or head If. The different sizes of drills are held in the drill-spindle h by the set-screw h and the turret-head is drawn back each time that the driving-spindle D is moved backward by the spring 9 thereby drawing the drills out of the wheel or the tire and fellies thereof, and in the process of drilling, as hereinbefore described, the driving-spindle D forces the turret-head G away from the plate 9 and the sleeve 9 connected therewith, by drawing the turretspindle g therethrough and by compressing the spring g between the cross bar a and the plate 9 After releasing the lever F the spring 9 draws the turret-head G back to its place, or to the position shown in Fig. 3, and the driving-spindle goes back far enough to allow the turret-head to be revolved in such manner that the drill-heads H will not strike the end of the driving spindle.

The turret-head G is held in each respective position by means of the pin or pins g", connected with the end of the sleeve 9 and operating in connection with the corresponding hole or holes g ,for1ned in the turret-head, and in order to avoid confusion we have only shown one of the drill-heads in Fig. 3 but it will be understood that any desired number thereof may be employed,and the inner end of the turret-spindle 9 projects within the rim of the pulley d which is mounted on the driving-spindle so as to employ as little space as possible, and by means of the vertical and longitudinal adjustment of the wheel-cup we provide for drilling wheels of different diame' ters and provided with tires and fellies of different widths or thicknesses.

In Figs. 7, 8, and 9 we have shown a modification of the turret-head shown in Fig. 3, and hereinbefore described, and this form of construction may be adapted instead of that shown in Fig. 3, if preferred. In this construction each of the drill-heads is capable of longitudinal movement independent of the other and slides on or in the head G. In this form of construction we provide a tubular head G, which is provided with a central bore drilled to within about one-half inch of the outer end thereof, and the outer surface of the tubular head G is provided with a plurality of dovetailed grooves N, four of which are shown in Fig. 8, and the drill heads or sleeves H are provided with shanks n, to which are secured or on which are formed arms M, which are adapted to slide in said dovetailed grooves, and passing through the inner end of each of said arms is a set-screw O,the inner end of which passes through a slot 0 formed in the bottom of the dovetailed grooves, and the inner end of the set-screw O is reduced in size and adapted to enter an annular groove 0 formed in the spindle g. The spindle 9 may be connected with the frame of the machine in any desired manner, and that portion of the end thereof within the turrethead G is reduced in size, and mounted thereon is a spiral spring 9 and mounted on the inner end of the reduced portion of the spindle g is a tubular sleeve P, the outer end of which is provided with a flange F on which is formed one or more projections or shoulders P.

It will be understood that any desired number of the drill-heads H may be employed, and that each turret-head G maybe provided with any desired number of the dovetailed grooves N, and that a corresponding number of the drill-heads H maybe employed, and that each of said drill-heads is provided with an arm n and a set-screw O, and that each of the dovetailed grooves N is provided with a slot 0 which communicates with the central bore of the turret-head, and the shoulders or projections P are adapted to operate in. connection with the inner ends of the set-screw O, which project through the space between the turret-head and the reduced end of the spindle g and into the annular groove 0 formed therein. Said spindle g is also provided at-one side thereof with a longitudinal groove or recess R, in which the inner end of the setscrew 0 is adapted to slide; and in the operation of this form of construction when the drive-spindle D is operated and brought in contact with one of the drill-heads the arm a connected therewith, is forced outwardly, and in this operation the inner end of the set-screw 0, connected therewith, slides in the groove R in the spindle g, and said setscrew compresses the spring 9 by forcing outwardly the sleeve P, and each of the other drill-heads is held stationary by the inner end of the set-screw 0, connected therewith, which remains in the annular groove 0 and whenever the drive spindle or shaft D is moved backwardly the spring 9 will at once return the drill-head, which has been forced outwardly, to its normal position, in which position the inner end of the set screw O,connected therewith, will project through the annular groove 0 in the spindle g, and the tripod-head may be again revolved, so as to bring another drill-head in line with the driving-spindle. It will thus be seen that this form of construction is substantially the same in the results produced as that hereinbefore described, the principal difference being that in this form each of the drill-heads moves independently of the other or slides independently thereof.

It is evident that other changes in and modifications of the construction herein described may be made without departing from the spirit of our invention or sacrificing its advantages; and we reserve the right to make all such changes in and modifications of the construction as fairly come within the scope of the invention; and though we have described our improvement as a machine for drilling wh eel-tires, &c., it is evident that the same may be employed for drilling many other articles and as a drilling-machine for general purposes.

Ve also employ an idler by means of which two different speeds may beobtained without stopping the machine, and this device is operated so as to loosen one of the belts E or E and tighten the other, and it is connected with the side of the frame and consists of the parts S, S S and S, which are connected by means of set-screws, but these devices form no part of this invention and the construction and operation thereof are not therefore described in detail.

Having fully described our invention, we claim as new and desire to secure by Letters Patent 1. In a machine for drilling the tires and fellies of a wheel, the combination of a drivin g spindle or shaft, a revoluble turret mounted in front thereof, and provided with drillheads which are adapted to be brought in line therewith, said machine being also provided with a wheel-cup which is adapted to receive the hub of a wheel and to support the wheel in horizonal position in such manner, that the tire thereof, will be in line with the driving or drill shaft, and said frame being also provided with an adjustable plate provided with a block or head which is adapted to press upon the inner side of the felly of the wheel, and said frame being also provided at each side of said adjustable plate with vertically-adjustable supports for the tire of the wheel, and with a plate-spring which is adapted to press upon the upper side of the tire, and a rod pivotally connected therewith and with a foot-pedal, substantially as shown and described.

2. In a tire-drilling machine, the combina tion of alongitudinally-movable driving spindle or shaft, and means for operating the same, of a plurality of drilling-heads each of which is connected with a central head which is revolubly mounted on a spindle, and each of which is provided with a drilling-spindle, with which a drill or other tool may be connected, and each of said drilling-heads being also adapted to be brought in line with the driving spindle or shaft, and said central head with which the drilling-heads are connected, being also longitudinally movable, and the spindle by which it is supported being passed through a plate provided with a sleeve or tubular extension, and which is connected with the frame of the machine, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of the subscribing witnesses, this 18th day of January, 1896.
