SPECIFICATION forming part of Letters Patent'No. 421,417, dated February 18, 1890.
Application filed August 8, 1889. Serial No. 320,130. (No model.)
To aZZ whom it may concern.-
Be it known that I, JACOB HERBERT M101;- LER, mechanic, of the village of Preston, in the county of lVaterloo, in the Province of Ontario, Canada, have invented a certain new and Improved Three-Spindle Boring-Maphine, of which the following is a specificaion.
The object of the invention is to design a three-spindle boring-machine, the spindles of the boring-machine being made adjustable to eachother, so that the holes to be bored may be closer to or farther from each other or at different angles to each other to suit different classes of work; and it consists, essentially, of a central spindle journaled in a stationary frame and provided with a suitable driving pulley, through which the necessary motion is imparted to it, a spindle having a frictionroller fixed to it being journaled in adjustable boxes on each side of the said central spindle, each frictionroller being held in contact with a friction-roller fixed to the central spindle, the end of each side spindle being c011- nected by means of an adjustable ball-andsocket joint to a spindle carried in suitable bearings supported by a hinged plate, the Whole being otherwise constructed in detail, substantially as hereinafter more particularly explained.
Figure 1 is a perspective View of my improved machine, showing one of the boringspindles set at an angle to the other spindles. Fig. 2 is a detail of a friction-pulley and its hearing.
In the drawings, A is a boring-spindle suitably journaled in bearing-boxes attached to a stationary plate B.
O is a driving-pulley fixed to the spindle A, and D is a friction-pulley fixed to the same spindle,
E and F are, two boring-spindles located one on each side of the spindle A. These spindles are carried in suitable bearing-boxes attached to one or other of the plates G, which are hinged to the plate B, as indicated.
011 each side of the friction-pulley D, I 10- cate a friction-pulley H, which is connected to aspindle O, journaled in a box I, pivoted on a spindle J, connected to the hinged plate G, which plate, I should have mentioned, is hinged on the central boring-spindle A. Each box I is acted upon by a spring K and setscrew L, so that the pressure of its frictionpulley II against the friction-pulley D may be readily regulated. A spring M is placed on each of the spindles J to impart an elastic longitudinal pressure against the box I, and a set-screw N is provided for each box I to adjust it longitudinally. The boring-spindles E and F are connected, respectively, to one of the spindles O by a link P, arranged to form a double ball-and-socket joint between their respective spindles. Owing to this balland-socket connection the spindles E and F may be moved independently of each other without affecting their driving-spindles O,'or in any way interfering with the satisfactory working of the machine.
I should have mentioned that the bearingboxes of the spindles E and F, which rest upon the hinged plate G, are made adjustable on the said plate and are operated by a spindle Q, so that each spindle E or F may be adjusted independently of the other nearer to or farther from the boring-spindle A to suit the position of the'hole it is desired to bore.
lVith the View of enabling the hinged plate G to be held at any desired angle I pivot on the said plate a bar R, which bar passes through a stationary sleeve S and is held at any desired point by the pinchscrew T.
From this description it will be seen that I have produced a boring-machine in which the spindles, although driven from a common power, are independently adjustable and may be set at any desired distance apart or at any desired angle to each other.
What I claim as my invention is- 1. A spindle A, having a friction-pulley D fixed to itand engaging with friction-pulleys H, fixed, respectively, to a spindle O, in combination with the boring-spindles E and F, each of which is connected to one of the spindles O by means of a flexible joint, substantially as and for the purpose specified.
2. A spindle A, having a friction-pulley D fixed to it and engaging with 'frictionpulleys H, fixed, respectively, to a spindle O, the boring-spindles E and F, each of which is con- 10o nected to one of the spindles O by means of a flexible joint, in combination with the adjustable spindle Q, arran ed to operate the bearing-boxes of the spin les E and F, substantially as and for the purpose specified.
3. A spindle A, having a friction-pulley D fixed to it and engaging with friction-pulleys H, fixed, respectively, to a spindle O, the boring-spindles E and F, each of which is connected to one of the spindles O by means of a flexible joint, in combination with the hinged plate G, supporting the driving and boring spindles, and the adjusting-spindle Q for independently operating the bearingboxes of the spindles E and F, substantially as and for the purpose specified.
4. A spindle A, having a friction-pulley D fixed to it and engaging with friction-pulleys H, fixed, respectively, to a spindle O, the boring-spindles E and F, each of which is connected to one of the spindles O by means of a flexible joint, in combination with the hinged plate G, bar R, sleeve S, and pinchscrew T, substantially as and for the purpose specified.
5. A spindle A, having a friction-pulley D fixed to it and engaging with the friction-p111: leys H, fixed, respectively, to a spindle O, which spindles are carried in elastically-adjustable boxes I, in combination with the boring-spindles E and F, flexibly connected to their respective spindles O, substantially as and for the purpose specified.
