JOSEF POHL, JR., OF DEUTZ, GERMANY.
BORING AND DRILLING MACHINE.
SPECIFICATION forming part of Letters Patent N o. 652,978, dated July 3, 1900.
Application tiled February 2, 1899. Serial No. 704,215. (No model.)
T all whom t may concern:
Be it known that I, JOSEF POHL, Jr., engineer, a subject of the Emperor of Germany, residing at Mathildenstrasse 58, Deutz', near Cologne, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Boring and Drilling Machines, of which the following is a full, clear, and exact description.
My invention relates toboring and drilling machines, and has for its object to provide a machine for use on large pieces of work in which a number of holes are to be bored or drilled. In boring and drilling machines of this kind at present in use the tool is generally carried by a plate or part sliding in suitable guides in the form of a bracket extending over the work and the tool is adjusted by hand feed mechanism also carried by the.
sliding part. In these machines when operating upon large pieces of work the feed mechanism is very difficult of access and the tool being carried by the bracket is very liable to inaccuracy in work, owing to the Weight of the part-s and their distance from the supporting-frame of the machine. The wear and tear of the parts is also considerably increased from the same cause. To overcome these defects, I construct and arrange the machine in such manner that the pressure or feed is communicated to the tool from a slide or support carried upon an adjustable guide-bar which is independent of the adjustable support controlling the position of the tool.
In further description I Will refer to the ac-v companying drawings, in Which- Figure 1 is an elevation, Fig. 2 an end View, and Fig. 3 a transverse section, of a machine constructed in accordance with my invention.
A is a supporting-frame formed of suitable uprights and cross-bars, in which are mounted guide rods or bars b b', one o f which, b', is helically threaded and provided on one end with a hand-wheel d. Mounted upon the rods b b' is a tool-support c', internally threaded and adapted to be moved along the same by rotating the rod b', so as to adjust the position of the tool-carrier in a longitudinal direction.
I may in some cases substitute a plain bar for the rods b h', the tool-support c being adjusted thereon by clamps or otherwise suitably. The tool-socket c and spindle h are adapted to move vertically in and independently of the support c and are raised or lowered by bar n, adjustable vertically in suitable guides on the side posts of the frame A. In the drawings levers, such as o o', are shown suitably mounted in the frame, as at 02 o2, and connected at their lower ends by links, such as q, to the bar n and at their upper ends to an operating-lever p. The latter is fulcrumed at p' and may be operated by hand or arranged for operation by a depending chain, as shown. The tool-socket o is connected to the bar n by a yoke m sliding therevon in suitable flanges or guides, such-as lm',
riage moving on rails, such as r r, and adapted to be adjusted transversely by a rack f, a toothed pinion f meshing therewith and hand-wheel g. When for use with work of considerable height, the upper part of the frame A and table E may be constructed so as to be adjustable vertically.
It will be seen thatby the use of a boring and drilling machine constructed as above the position of the tool is adjustable both transversely and longitudinally and equally Well with both large and small work, and the tool being supported independently of the sliding port c the inaccuracies in work and Wear and tear referred to are obviated.
What I claim, and desire to secure by Letters Patent, is
In Aa boring and drilling machine, the combination of a supporting-frame,"a threaded bar mounted in said frame, a tool-support longitudinally adjustable on said bar, a tool- IOO spindle and socket vertically movable in and In Witness whereof I subscribe my signarotatably mounted in said tool-support, a bar ture in presence of two witnesses. vertically movable in the machine-frame and having a slidable connection with the tool- JOS' POHL JR' 5 spindle, and means for vertically moving said Witnesses:
bar, consisting of levers and links as shown HEINR. SOHLNER, and described. XVILLIAM I-I. MADDEN.
