HEAD-`WOTION FOR ORE-CONCENTRATORS.
Specication of Letters Patent.
rammed Dec. 3, reis.l
Application filed June 26, 1918. Serial No, 241,944.
To all whom t may concern:
Be it known that I, CHARLES C; HEBBARD, a citizen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Head-Motions for the following is a specification, reference being had to the accompanying drawings.v
his invention relates to concentrating tables, and particularly to a head motion which, while adapted Afor other purposes, is designed for imparting a reciprocating mo tion to a concentrating table.
One obj-ectof the invention is to provide improved means for this purpose of a very simple character and which includes an overbalanced fly wheel, means for transmitting the oscillating motion transmitted to this tiy wheel because of its being overbalanced to the deck itself, or other device Vto which the reciprocating motion is to be applied, and provide improved means for regulating or controlling the degree of movement of the table or other device acy cording to the circumstances of operation.
A further object is to provide improved means for supporting the Ovnrbalanced fiv wheel whereby the fly wheel may have tree reciprocation parallel to the axis of the table, without: there being any action tend* ing to tear the shaft of the liy wheel from its bearings.
Still another object is to provide improved means for adjustably limiting the stroke of the 'bumper block which ,gives a reciprocating motion to the table`r this means including the provision of variable layers of material mounted upon the bumper block and engaging with the bumper.
A further object `is to provide yielding means for resisting a movement; of the bumper under the impact of the bumper block and provide for an adjustment of the tension of this vieldinpT means. Other objects will appear in the course of the following description.
My invention is illustrated in the accompanying drawings, wherein Figure lv isv a side elevation of a head motion constructed in accordance with my invention;
Fig. 2 is a top plan' view, partly in section;
Fig. 1; and
Fig. 4 is a fragm ntary top plan view to show the manner holding the bumper facing to the bumper block.
Referring to these drawings, 10 designates the side beams of a base or floor frame. These extend parallel to each other. Supported above these side Vbeams is the object 3 is a section on the line 3-3 of Fig.
to be reeiprocated which is illustratedas the deck of a concentratin table. This deck is supported ii any suitable manner, the particular manner of forming the deck forming no part of my present invention. As illustrated, however, the deck is supported upon vertically extending. resilient supporting members 12. The deck 13 is mounted upon the deck supporting beams 11 and is of any usual-construction.
Supported upon the beams 10 at the head end of the table is a base plate 14 illustrated as supported upon longitudinal beams 15 and transverse beams 1G which in turn rest upon the beams l0. Attached to the base plate 14- at each end thereof, and extending downward over the beams 15 are the hangers 17 having bearings ai their lower ends through which passes a transversely extending pivot-.or shaft 18. Pivoted upon the shaft 18` areithe upwardly extending arms 19 having bearings at the upper ends for a transverse shaft 20 and mounted on the shaft 20 inward of the arms 19 are rods 28 having heads 21 through which the shaft 2O passes. Mounted on the shaft 20 is a loose wheel 22 and an overbalaneed pulley or fly wheel 23. A drivingr belt 24 is arranged to be shifted to either one of these pulleys.l
As illustrated in Fitz. pnllev or flywheel 23 is 1, the unbalanced formed with a web Q5 through which a bolt 26 basses and bv' ed to a bumper block Q9 by bolts 30 passing porting arms 19 and through the rods 0r y through the flanges. Attached to the other faces of the bumper block 29`iare rods 31 which at their oppositev ends have lianged heads 32 bolted to the transverse beam 33 at the head end of the table.
The rods3l are provided at their rear ends with flanges through which the bolts 30 pass. The middle of the bumper block 29 'is provided with a facing 34 of leather or other material held in place by clips 35. This facing is made up of a plurality of layvers of leather or othermaterial and these which has screw-threaded engagement with the rod 37 and constitutes a nut bearing against the compression spring and the rotation of this hand wheel or nut acts to increase or decrease the tension of the spring 38.
The operation of this portion of my invention is as follows: Assuming that the belt 24 is in engagement with the balanced pulley or fly wheel then it will be obvious that as the unbalanced wheel is rotated through the driving belt, an oscillatory movement will. be given to the shaft 20 and the supbars 28 to the bumper block and'from the bumper block through the arms 31 tp ,the
deck. Thus a reciprocating motion will b'e.
given to the deck but in order to provide for* a sudden jar being given t0 the deck, I provide the projecting bumper 36 which constitutes a stop against which the bumper block impacts.
When the bumper block 29 impacts against the bumper 36, the forward movement of the bumper, of the rods 31 and of the deck is suddenly checked and then as the weighted portion of the unbalanced fly wheel or pulley moves rearward, the bumper block 29` the rods 31 and the deck are drawn backward against the force or tension of the spring 38 which thus acts as a means for yieldingly limiting the rearward movement ofthe table. By rotating the hand wheel 40 which constitutes a nut, it is possible to increase or decrease the tension of this spring 38 and thus variably control the resstance of the rearward movement of the table and consequentl` control the extent of this rearward movem nt. he loose pulley 23 acts as an idler to ,'rest ain or stop the movement of the deck. i
In the,` operation of this device, when the belt is shiftedupo'n the idler pulley, it is.
obvious that no reciprocation of the table will be secured, but when the belt is shifted onto the overbalanced pulley or wheel 22, then the rotation of this wheel will cause the wheel to move forward and rearward in sie connection with the pivoted arms 19 and this forward and lrearward movement will be transmitted to the cross beam 33 of the deck .by means of the rods 28 and 31. When the anced fly wheel, the spring 38 will be cornpressed and this compression of thespring will resist the rearward movement of .the
table to an extent depending upon the tension et' the spring; This tension is, of. course, regulated by adjusting the handv wheel 40. y
It. will be seen that I have provided a mechanism for reciprocating the table including a vpower driven member which is constantly rotatable and which is not stopped or impeded inits rotation in any manner as would bethe case were a power driven cam used for reciprocating the table, and furthermore, I secure by the use of an unbalanced fly wheel, 'a stroke of a power not possible if a cam were used for urging the table forward.
While I have illustrated a mechanism em.-
'bodying my invention which I have found to be thoroughly effective in practice, yet'it `will be understood that the details of this "mechanism and arrangement of the several parts may be variedin many ways, without departing from the spirit of the invention, as delined in the appended claims.
