9 Claims.
This invention relates generally to fixtures for holding spherical members and it relates more particularly to a universally adjustable fixture for holding bowling balls for drilling the finger holes therein.
Fixtures heretofore devised for holding bowling balls required a new setup for the drilling of each finger hole. The layout of the distances between the finger holes is extremely difficult and it is also extremely difiicult to drill the finger hole in a ball at the correct angle. No fixture for a bowling ball has heretofore been provided which permits all holes of the ball to be drilled after the bowling ball is clamped in the fixture, which permits universal movement of the bowling ball after clamping in the fixture and which permits one or more holes to be drilled of any size or depth, any angle, and any span without loosening the clamping ring.
It is, accordingly, an object of my invention to overcome the above and other defects in fixtures for holding a spherical member and it is more particularly an object of my invention to provide a fixture for holding a bowling ball which is simple in construction, economical in cost, economical in manufacture, and efiicient in operation.
Another object of my invention is to provide a fixture for holding a spherical member which permits universal movement of the spherical member after it is clamped in the fixture and which has measuring means provided for measuring rotative movement of the spherical member in different planes.
Another object of my invention is to provide a fixture for holding a bowling ball for drilling finger holes therein which provides a clamping ring for clamping a ball therein wherein one or more finger holes may be drilled in the ball to any depth, any angle, any pitch, and any span without loosening the clamping ring.
Another object of my invention is to provide a bowling ball fixture which permits universal movement of the ball after it is clamped and which also permits linear movement of the fixture in directions normal to each other.
Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawings, in which Fig. 1 is a plan view of my novel fixture for holding a sypherical member; 7
Fig. 2 is a side elevational view in one plane and Fig. 3 is a side elevational view in another plane of my novel fixture for holding a spherical member;
Fig. 4 is a fragmentary plan view of the bifur- I cated yoke on the clamping ring of my novel fixture;
Figs. 5 and 6 are side elevational views of interenga-ging locking collars disposed on two sides of my novel fixture at right angles to each other;
Figs. 7 and 8 are side elevational views of interengaging locking collars disposed on the sides of my fixture opposite the collars shown in Figs. 5 and 6; and
Fig. 9 is a fragmentary sectional view taken on the line 2-9 of Fig. 1 showing the locking collars in Figs. 5 and 6 in engagement.
Referring now to the drawings, I show in Figs. 1 to 9 inclusive 2. base plate I having upwardly extending, projecting portions 2 and an upwardly extending, right angled apertured bracket 3 welded thereon. The base plate I may be mounted on a conventional bed of a drill press or any other suitable machine tool. The base plate I has slidably supported thereon a plate 4 having an outwardly and upwardly extending, right angled apertured bracket 5. A feed screw 6 is journalled in the aperture of the bracket 3 and threadably engages an internally threaded bracket 1 secured to the plate by screw bolts 8. The screw 6 has a hand wheel 9 mounted on the other end thereof and secured thereto by a nut [0.
A plate i2 is spaced upwardly from the plate 4 and slides on upwardly extending support members 13 on the plate 4 normal to the direction of movement of the plate 4. A feed screw I5 is journalled in the aperture of bracket 5 and it threadably engages a threaded aperture H3 in standard I! mounted on the plate l2. It will thus be seen that by rotation of the handles 9, the feed screw 6 will rotate in the threaded bracket 1 causing the plate 4 to move in one direction in one plane. When the hand wheel l8 mounted on the feed screw I5 is rotated, the plate 42 is moved in a direction in a plane opposite from that of the plate 4. The plate l2 has a pointer 19 secured thereon by a screw 20 to register with graduations 22 on the plate 4 to measure the movement of the plate l2 with reference to the plate 4. Any suitable form of bed which may be moved in planes normal to each other may be utilized for carrying out my invention.
Vertically extending, spaced, parallel standards l1 and-2| extend upwardly on the plate l2 and are secured thereto. A circular rotatable support ring 23 has oppositely, outwardly extending stub shafts 24 and 25 journalled in the standards I1 and 2| and clamped therein by arcuate shaped clamps 26 and 2'! secured'to the standards I! and 2| by screw bolts 28 and 29. Lock collar 39 shown particularly in Fig. 5 has an aperture 32 through whichthe shaft 24 extends and it is secured to the standard [1 by screw 3|. The face of the collar has radially extending splines 33 for engagement with radially extending splines 34 on a collar 35. The collar 35 has a. square aperture for engagement with a square portion 3'! of shaft 24 and it is movable therewith. The collar 35 is secured by a handle 39 which is threadably engaged with the threaded end 40 of shaft 24. The collar 35 has a sector 42 with graduations 43 around the periphery" thereof adapted to be registered with a pointer 44 on the depending portion 45 of collar 30. The
The stub shaft 25 on the opposite side of the ring 23 is constructed the same as the stub shaft 24"shown in Fig. 9. Collar 59 shown in Fig. '7 is secured to the standard 2| by a screw bolt 5|.
It has an aperture 52 through which extends the shaft 25 and it has a radially splined face portion 53. A collar 54 with a square axially extending aperture'55'is disposed on the square portion of the shaft 25 and it rotates with the shaft 25. The collar 54 has a radially splined face portion 56 for engagementwith the splined portion 53 of thecollar 50 to lock the ringmember 23 'at predetermined angular positions. The
A circular saddle 60 in the'shape of a segment of a sphere has outwardly extending stub shafts 59 the same as the'stub shaft 24 shown in Fig. 9. The stub shafts 59 on the saddle G9 are journalled in journals 62 and 53 secured by welding or any other suitable means to the outer side of the ring 23 at right angles to the stub shafts 24 and 25 on the ring 23. A collar 30 is attached to the journal 63 and engaging collar 35 and handle 39 have the same construction and operation as heretofore described for the same elements on shaft 24. Collar 50 attached to journal 62 and collar 54 movablewith the shaft59 on the saddle- 69 and the handle 58 are identically the same in construction and operation as the same elements mounted on the shaft 25 of the support ring 23.
A circular clamping ring 65 in the form of a segment of a sphere has outwardly extending, bifurcated yokes 66 on opposite sides thereof for engaging pivoted screw members 5'! pivoted at 58 on the upper end of the journals 52 and 53.
Internally threaded, manually, rotatable screw members 69 threadably engage the threaded bolt members 61 to secure the clamping member 65 on the upper side of a ball 10 seated in the saddle 6D. The screw members 69 have an enlarged knurled head portion 7| so that they may be better grasped and tightened manually.
I will describe the operation of my fixture with reference to a bowling ball although it will be evident that any spherical member may be ac-. commodated. In Fig. 1, I show a three fingered bowling ball clamped in my novel fixture. The centers are first laid out for the finger holes after which the ball is disposed in vthesaddle 66 and clamped therein by the ring. clamp 65. The hand wheels 9 and I8 are then rotated so as to bring a center hole laid out on the bowling ball adjacent thepoint of a drill. The desired angle of the'hole is determined, the handles 39 and 58' are loosened, and theball I0 is rotated in two directions at right angles to each other until the desired angle is obtained. This desired angle can also be obtained mathematically and the graduated sectors 43 may be utilized to position the ball 19 at the correct angle for drilling. The handles 39 and 58 are then rotated to lock the collars 30 and 42 and 50 and 54 respectively and the hole is drilled. After one hole is drilled, the drill is removed and the handles 39 and 58 are loosened and the ball 10 is rotated through two different planes to bring another one of the holes underneath the drill wherein the ball 10 is placed in a proper angular position by reference to the graduated sectors 43, the members 39 and 58 are tightened whereby the saddle and ring 23 are locked, and the second hole may then be drilled. The same-operation is performed for the third hole of the bowling ball 10.
It will be evident from the foregoing description that after the bowling ball 10 is clamped by the clamping ring 65, it is not necessary to release the ball 18 and all settings may be made simply, quickly, accurately, and easily by the manipulation of rotatable handles forming a part of the machine, without the use of any hand tools, and means are provided for measuring the angles through which the ball passes to asoertain thespan, the angle to which the drill enters the ball, and all otheressential measurements for accurately drilling a bowling'ball. It will further be evident that any form of spherical comprising spaced, vertically extending support members, a circular frame pivotally supported on said support members, a circular cradle for holding a spherical member, outwardly extending shafts on said circular cradle pivotally supported on said circular frame and rotatably movable at right angles to the rotative movement of said circular frame, a circular clamping ring hinged on said frame complementary to saidv cradle adapted to be disposed over the upper side of a spherical member seated in said cradle, a clamping member detachably connecting said cradle and said clamping ring in a locked position in relation to aspherical member in said cradle, and outwardly directing handles on the shafts on said circular cradle in said frame for rotating same.
2. A fixture as set forth in claim 1 wherein means are provided for locking said circular frame and said cradle in predetermined angular positions.
3. A fixture as set forth in claim 1 wherein said support members are movable in linear directions 7 at right angles to each other.
4. A fixture as set forth in claim 3 wherein means are provided for indicating the linear movement of said support members.
