MUllTIPLE-SPINDLE DRILL Specification of h'etterslatent.
Application filed August 13, 1913. Serial No. 784,469.
citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Multiple- Spindle Drills, of which the following is a specification.
/ My improvements are comprised in a machine having a -plurality of drill spindles revoluble, by flexible shafts of variable length, in radius bars which are longitudinally adjustable relatively to a center and fixed to a supporting ring carried by the machine frame. The spindles are vertically adjustable by means of sleeves in which they are revoluble and which are moved vertically, in the respective radius bars, by threaded cylindrical segments thereon engaged by screws journaled in the respective radius bars.
In the accompanying drawings, Figure 1 is a part sectional elevation of a machine embodying my improvements; Fig. 2 is a broken sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is a sectional View taken on the line 3-3 of Fig. 1; Fig. 4 is a sectional view taken on the line 4- 1 of Figs. 2
/ and 5'; and Fig. 5 is a sectional view taken on the line 5-5' of Fig. 4. V
The machine, as illustrated in the drawings, comprises the frame or housing 1 having fixed thereto the ring 2 for supporting the radius bars 3. Bolts 4 are engaged in the ring channels 2, pass through the bars slot-s 3 and engage the clamping plates 5, whereby the bars are fixed to the ring.
Each. radius bar 3 has iii the inner end thereof, within the ring 2, a vertical bearing 3 in which is a longitudinally movable sleeve. 6 on a drill spindle 7 which is revoluble therein,t-he spindle being movable vertically by the sleeve through the latters engagement with the ring 7* and knuckle 7. Each radius bar contains a vertical screw or worm shaft 8 having the journals 8 and 8 revoluble in the bearings 3 and 3 the screw engaging a complementary nut section or threaded cylindrical segment 6 on the sleeve 6 and having the socket 8 for the engagement of a wrench. 5
The spindles 7 are revolved in the sleeves on a rod 11 t3 by the sleeves 9 having the knuckles 9 oined to the knuckles 7 by the connected transversely a gimbal joint. Each sleeve 9 1s telescoped containing a longitudinal groove extending journals 10, forming Patented May 26, 1914. g
11 in which is engaged a feather 9 fixed within the sleeve 9, the parts 9 and 11 formmg a shaft .of variable length. Vertical arbors 12, is supported by the ring 2, have thereon knuckles 12 joined to knuckles 11 on the shafts 11 by the connected transversely extending journals 14.. Pinions 15, fixed on the arbors 12, are driven by'a spur wheel 16 fixed on an arbor 17 which is journaled in the housing 13 and; has a spur wheel 18 fixed thereon. An arbor 19, journaled in the housings 1 and 13, has fixed thereon a pinion 20 which drives the spur wheel 18, the arbor being driven by its pulley 21 and a belt 22 thereon which passes over the pulleys 23 to the driving pulley 24.
The adjustment of the radius bars 3, the revolution of the spindles 7 in the various positions to which they may be adjusted, and the adjustment of the elevation of the various spindles, are rendered practicable by the adjustability of the length of the respective shafts comprising the parts 9 and 11' and the universal joints by which these shafts are connected with the spindles 7 and the arbor-s 12, while the revolution of the screws 8 moves the sleeves 6 vertically through the bearings 3 to adjust the elevation of the spindles with the drills therein, the worm and sleeve holding such spindles in the desired positions. I
journaled in a housing. 13 which 1. The combination of an adjustable radius bar, a sleeve movable longitudinally in said bar, said sleeve having an exterior threaded segment, a screw ournaled in said 'bar,1said screw engaging said segment, and
a drills indle journaled in said sleeve, said spindle'iieing connected with said sleeve so as to be movable longitudinally thereby.
2. The combination of an adjustable member having a bearing, a sleeve with a threaded cylindrical segment movable longitudinally in said bearing, a worm journaled in said member in engagement with said segment, a drill spindle journaled in and mov- 5 joint connecting a second section of said able longitudinally by said sleeve, van arbor, my hand this fifth day of August, 1913, in
