'1 Claim.
This invention relates to a device designed for directing cutting oil or fluids under pressure, to the work positioned on metal drilling machines.
An important object of the invention is to provide a cutting fluid pump for drilling machines which will direct the cutting fluid to the center of the work, rendering the device especially adapted for small work.
-will of the operator, and with each operation of the pump.
Still another object of the invention is to provide a cutting fluid pump which is of the portable typ and may be readily and easily transferred from one machine to another.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawings Figure l is a side elevational view of a. metal drilling or boring machine, illustrating a cutting fluid pump constructed in accordance with the invention, mounted thereon.
Figure 2 is an enlarged vertical sectional view through the-reservoir of the pump, illustrating the pump as mounted therein.
Figure 3 is a plan view of the device.
Figure 4 is a sectional view taken on line ll, Figure 2.
Figure 5 is an elevational view illustrating the switch which controls the operation of the pump.
Figure 6 is a sectional view taken on line 6-8 of Fig. 5.
Figure 7 is a sectional view through the nozzle of the device.
Referring to the drawings in detail, the reference character 5 indicates the main post of a boring or drilling machine, the drill oi the machine being indicated by the reference character 6.
The device forming the essence of the present invention, is constructed to be clamped to the main post 5, in a manner as shown by Fig. 1 of the drawings, and comprises a reservoir I which is in the form of a jar constructed of transparent material.
The reservoir includes a cover I which is formed with a flange adapted to flt over the open end of the reservoir, as shown by Fig. 2 of the drawings. The flange is formed with openings disposed directly opposite to each other, one of the openings being designed to receive the extension 9 of the clamp in used in clamping the cover to the reservoir. The clamp embodies a length of wire material ,curved to conform to the shape of the open end of the" reservoir, the ends of the wire indicated at H extending through one of the openings of the flange, where they are extended laterally, providing finger pieces l2. Under nor-. mal conditions, the clamp will grip the reservoir adjacent to the open end thereof, securing the cover in position=---Tli ends of the wire of which the clamp is formed, are crossed so that when the finger pieces are pressed towards each other,
the clamp will expand to release the reservoir.
Secured to the cover 8, is a clamp indicated generally by the reference character IS, the clamp including curved arms I adapted to be positioned on the main post 5, so that the arms grip the post, and support the device in position.
Supported by the cover 8, and extending through the flange thereof, is a pipe I! which has its inner end extended downwardly as at I, where it is disposed centrally of the reservoir. The inner end 16 provides a support for the electromagnetic windings I! which are enclosed in the casing it which is of a length greater than the length of the magnetic windings l1, providing a compartment 19 below the magnetic windings l'l.
Operating within the inner end It oi the pipe 15, is a hollow plunger 20 which is constructed of magnetic metal, to provide the core for the electromagnetic windings l1, so that the plunger will act as the core of a solenoid.
Mounted in the upper end of the hollow plunger 20,.is a one-way valve II which is adapted to seat on the upward movement of the plunger 20, to force fluid from the compartment IS.
The lower end of the plunger 20 is flared and provided with an enlarged tapered opening through which the fluid passes into the plunger, as the plunger moves downwardly under its weight.
Extending through a threaded opening in the bottom of the casing II, is an adjusting screw 22 which carries the disk 23 at its inner end, the disk providing a support for the plunger 20, to restrict the downward movement of the plunger and consequently regulate the action of the plunger to control the quantity of fluid which provided with a spring-pressed ball 28 which will release the fluid under pressure from within the hose, but will close the end of the hose to prevent the fluid from flowing therefrom, under normal conditions.
Electric current is supplied to'the electromagnetic windings. through the cord II, which is provided with a suitablaplug so that it may be plugged into a wall socket, as shown by Fig. 1.
The electric circuit is controlled by means of the manually operated switch It which is provided 'with a clamp 28 that may be clamped to one of the arms of the adjusting device of the drill which is used in adjusting the drill tool while in use. Due to this construction, it will be seen that the operator, in moving the adjusting device, may, by operating the switch, cause a discharge of cutting fluid, at the work.
In the operation of the device, the operator will-complete the circuit to the electromagnetic windings Il intermittently, until suflicient oil or cutting fluid has been pumped into the pipe II and hose It, to fill them. with each movement of the plunger, subsequent to the filling of the pipe II and hose It, a quantity.of oil or cutting fluid held within the hollow plunger, 'will be forced from the nossle. -Whenthe electromagnetic windings become deenergised, it is obvious that the plunger will fall by gravity to the bottom of the casing, whereupon a quantity of oilwill be forced into the hollow plunger to be elected at the nozzle. with the upward movement of the plunger.
From the foregoing it will be seen that when it'is desired to reflll the reservoir, it is only necessary to disconnect the reservoir from the cover, providing'eas'y access to the reservoir. The reser voirwhen filled, maybe readily clamped to the cover, by the clamp Ill What is claimed is:
A fluid pump comprising a casing having an inlet opening, adapted to be submerged in a tank of liquid, a discharge pipe extending into the top of the casing and being connected with the casing, electromagnetic windings within the casing between the pipe and wall of the casing, a plunger constructed of'magnetic metal, operat-' ing within the discharge pipe adjacent to the electromagnetic windings, and adapted to be moved longitudinally of thedischarge pipe when said windings are energized, said plunger having a longitudinal bore flared at its lower end, a screw extending through the bottom of the easing, a disk on the inner end of this screw and against which the plunger moves, whereby fluid within the plunger is forced through the plunger into the discharge pipe, and further inflow of liquid to the plunger is cut oil, and a' valve adapted to control the passage of fluid through the plunger.
