Letters Patent No. 110,375, dated December 20, 1 870.
IMPROVEMENT IN STONE-DRILLING AND CHANNELlNG MACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, EBENEZER G. Limrson, of Windsor, in the county of Windsor and in the State of Vermont,-l have invented certain new and useful Improvements in Stone-Drilling and Channeling Machine; and do hereby declare that the following is a fn'll, clear, and exact description thereof', reference being had to the accompanying drawing and to the letters of reference marked thereon making a part ot' this specication. y
My invention relates to improvements in machines intended for use in channeling or drilling stone; and the invention consists in a novel construction of a yielding pitman, `and inthe manner of clampingand adjusting the cutters or drills, and also in arranging the cutters to play in bracket-guides, in order to dispense with the cross-heads and standard-guides heretofore used in this class of machines, all as hereinafter more fully explained ,and described.
v In the accompanying drawing- Figure 1 represents a side elevation of a machine embodying my improvements; and
Figures 2 and 3 are views of portions represented detached, the better to illustrate their special con-v struction.
lhe class ot' machines to which my present iinprovements are specially applicable is known as channeling-machines, and is used for cutting channels or grooves in the rock or beds of quarries, to -assist in getting out the stone therefrom. 4
These machinesare usually mounted on wheels, to run on a track laid on the rock; but as these features are well known,and have beenfully described in my former patents,I have, in A,this instance, shown my improvements applied to afsimplc form of stationary frame, the frame, in this case, only lbeing used'to show the operation of the other parts which contain my improvements.
A represents this frame, having a shaft, B, mounted transversely iuits upper end, and connected by a pulley and cord to a hand-wheel, for giving it motion.
Upon the front end of the shaft is secured a wheel,
O, which has a radial slot or groove, to receive and hold anadj ustable wrist-pin, the detailed construction of which is shown' in iig. 3, the groove, with the pin in it, being shown in iig. 1, itbeing the same as shown inmy patent of September 17th, 1867, and need not therefore be further described.
The yielding pitman which I have devised, and which is intended to be used asa substitute for thc bow-string, shown in my foriner patent, consists of two arms 'or rods, I, hinged orpivoted together at Vone end, and divcrging thence in the form of thc 1ctter V, Aat a greater' or lesser angle; Atheir opposite ends being connected by a 4leaf or other fiat spring, H, as shown in fig. 2.
To the center of this spring, midway between the' upper ends of the arms I, I secure a rod, G, the opposite end of which is provided with an eye to it'upon the wristpin.
In using this device one" end is connected to the wrist-pin in the usual manner, while its other extremity is secured by a free joint to the clamp F, which Y holds or is fastened to the cutters or drill4 J, as shown in iig. l. The pitman may be used either end up, but I prefer it as represented in the drawing.
It will, of course, be understood 4that the rod G may be made of any desired length. Vhere the driving-crank or wrist is near the clamp, this rod G maybe only long enough to have the necessary eye for connecting it to the wrist; and where these parts are far apart, the rod Gwill be made proportiouabl y longer, the main idea being to secure the function of elasticity or yielding.
It will be Aapparent that when the machine isset in f motion the spring H, with the hinged arms I, will yieldsomewhat, and thus operate to produce the saine beneiicial results 'as the bow-spring hereinbefore referred to. Y
In this class of machines it has heretofore been customary to construct them with standard-guides, and to clamp the drills or cutters in cross-heads, which played up and down on these standard-guides.
In my present machine I have dispensed with these Ystandard-guides and cross-heads entirely, and instead thereof, I provide the frame A-with two brackets D, which project from its face, one above the other, as shown in fig. 1. In these brackets I form suitable openings, with bearings, for the cutter J to play up and down in, as represented in fig. 1.
The opening' or hole in the brackets will of course beso formed as to afford a irm and steady bearing and guide for the cutter J, while the front ofthe hole or 'opening will be so formed as not to touch the teeth l or seri-ations on the front of the cutter. It' preferred,
the front of the bracket maybe cut away so as to be open at that point; but, it that be done, the sides will require to bc made heavier in order to have the necessary rigidity and firinnesss.
To secure the cut-ter to the pitman I make a clamp, F, which consists of a strong metallic loop or block, F, having a'wrist-pin or journal projecting from its rear side, on which the lower end of the pitinan is secured, as shown in lig. l. Through this block F is made a-hole v as long as the cutter J is wide,` and of 'a width about double the thickness of the cutter.
I then provide a block, K, which is of the proper size to fitin this hole in front of the cutter, its rear face being serrated to correspond with the sei-rations on the cutter J, and with a project-iiig-shoulder at top and bottom to hold it in place, as represented in g. l.
Through the front of the clamp F I then insert one or more set screws, L, with its inner end bearing on the block K, to press it tight against the cutter J and keep their serrations or teeth inter-locked, and thus hold the cutter tight in the clamp.
When it is desired to adjust the cutter higher or lower, it is only necessary to loosen the screw L, dis'- engage the block K from the cutter J, and then raise or lower the latter as desired, and secure it in place by tightening up the screw again. By this method of construction I dispense with'the complicated devices heretofore used, and greatly lessen the weight and expense of the machine,` and at the time making it simpler and easier to adj ust.
Having thus described my improvements,
WhatI claim as of my invention is- 1. The yielding pitman, consisting of the arms I itnessesz HENRY WARDNEB, L. W. HAWLEY.
