warren JOHN GAZO, OF DETROIT, MICHIGAN.
annAmN'e madame.
To all whom it may concern."
Be it known that I, J OHN 6mm, of the Republic of Czechoslovakia, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Abrading Machines, and declare the followin to be a full, clear, and exact description 0% the same, such as will enable others skilled in the art to which referdrawence being had to the accompanying of this specificaings, which form a part tion.
This invention relates to filing machines and the object of the invention is to provide a filing machine having a stationary casing provided with handles for holding the Same enclosing a driving mechanism for reciprocatin the file which is positioned therebeneath. A further object of the invention is to provide a filing machine in which the file is supported in the center on the head of a screw the said screw being adjustable to support the file at the center. A still further object of .the invention is to provide a filing machine having a reciprocable member to which several different types of files or abrasive members may be secured. These objects and the several novel features invention are herinai'ter more fully ,described and claimed and the preferred form of construction is shown in the accompanying drawings in which- Fig. 1 is a side elevation of a filing'machine embodying my invention.
Fig. 2 is a view of the filing machine with thecasing removed.
Fig. 3 is a erspective view of one of the abrasive m m ers adapted to be used in the filing machine.
Fig. 4' is a perspective view of an alternative type of e.
Fig. 5 is a section taken on line 5-5 of Fig. 2, the casingbeing broken away to show the construction.
Fig. .6 is a section taken on line 6-6 of 1 is provided at the end 2 As shown in Fig. 1, a casing the said casing being narrow and widened at the end 3 to enclose the driv-;
ing mechanism. On this casing 1 is secured a pair ofhandles 4 as shown In Fig. 1, the handles being so constructed as to be turned longitudinally or transversely of the casing. Secured in this casing 1 is a stationary member 5 which, as shown in Fig. 5, is grooved a citizen may be adjusted by the v the casing 1.
with this device provided with a pair. of
ber
to receive a reciprocating member 6. Secured to the reciprocating member 6 is a bifurcated member 7 in which arm 8 is pivoted, 'as shown in Figs. '2 and 5. Mounted on the side of the stationary member 5 is a stationary arm 9 which supports a bearing 10 for the shaft of a lar e gear 11. This arm 8 is pivotally secure at 12 to the face of the gear 11, as shown more particularly in Fig. 2. The frame member '5 is also provided with, an outwardly extending portion 13 which provides a support for the bracket'l on which an electric motor 15 is mounted as shown in Figs. 2 and 5.
extends outwardly through the casing on each side, as shown in Fig. 1, the button be.- ing, pushed from one end to close the circuit and supply current to the motor and being pushed from the opposite end to break the circuit and prevent operation of the motor. Leading from this switch is a pair of wires 18 and 19 adapted to be connected to a suitable source of current to supply current to the motor. The reciprocable member 6 is abrasive member is secured. Thisabrasive member may be of an ofthe well known types for working woo vent the same from curving at the center when downward pressure is applied there to I provide a short hexagon headed screw 23 threaded into the member 6, as shown more particularly in Fig. 2. This screw use of a wrench to support the center of the file in a flat position or curve the same outward to a slight degree. By this construct-ion the abrasive member is supported atboth ends and at the center thus preventing it from curving and drawing away from the work between the ends when downward pressure is applied to The abrasive member 24 used upwardly extending members 25, thryinem 6 in this instance being provided with. a pair of-screws extending therethrough andengagingjein the threaded apertures 26 in the mem' rs 25 thus supporting the member 24on the reciprocable member 6. A sheet of abrasive material 27 is positioned on this member 24 and to 'secure t e same thereto I provide a pair of spring members 28 at the opposite ends of the member 24 secured the end of an iii) Secured on the top of the motor is a switch 16 operated by a button 17 which.
'jrovided with a block 20 at one end and a block 21 at the opposite end to which .the
or metal and to pre- I thereto by become worn and unfit for use it is neceslow removal of the-abrasive vided fitting over the parts to ether on the bolt.
provide ticularly adapted to ,sary to remove the same and for this urpose I provide a lever 31--at each en of the member 24 which is pivotally supported in brackets 32. Itcan thus be seen that by pressing down on the ends ber 31- the spring clips may be lifted to alstrip 27 therefrom and also allow the insertion of a new abrasive'strip. In Fig. 4 I have shown an alternative form-of file which is adapted to be secured to the member 6 adjacent the end 21-shown in Fig. 1. This file 33 is secured in' a block 34 which the file and an additional block 35 is pro under surface of the file as shown in Figs. 4 and 6. A bolt 36 is' provided, shown more particularly in Fig. 6, which extends through the; block 35, through the file 33 and through the block' 34 and a nut-37 is provided binding the said The block 34 is with upwardly extending portions 35 at each-end which in turn are provided being passed through the reciprocable member 6 and engaging in these'threaded apertures 38 thus securing-the-block 34 to the reciprocable member 6 at one end. This block is adaptedto be so secured to the member 6. that the file 33 protrudes beyond the end 201 the casing 1. This file .is parand other places where it is impossible to position the casing over the work.
I nected- .toa suitable source of current and- I vIn operati0n the wires I8 and 19 are conthe operator, by means of the handles 4 on the casing 1, posltlons the abrasive member in contact with the work. When this has been done the'butt on 17 at the left of Fig. 1-
is actuated to close the circuit and set the motor 15 operation. During operation of thevmotor 15 the shaft 40 thereof is rotated. The gear 39 'inmeshwith the gear 11, the gear ind the of the memis grooved to receive I-d i to 'sustainthe same between the mth threaded apertures 38, a pa1r of screws used in apertures .at each end of the the gear 39.0n .the.end-of the casing 1 in a stationary position by the handle 4 while the abrasive member is reciprocated. The reciprocation of the file 22.
is much faster than possible by hand filing and therefore the filing is accomplished in a much shorter period and with much more ease than by the hand method.
. From the foregoing description it becomes evident that the device is very simple and eflicient in operation, of comparatively low manufacturing cost and of few parts and provides adevice which accomplishes the objects desired.
Having thus fully described my invention, its utility and mode of operation,;what
and desire to secure by Letters Patent of the United States is i 1. In a device of'the character described, aframe consisting of a base, .a *detaChable cover therefor'providing a housing, the base having a longitudinal Way therein, an abrasive. member comprising a bar in the way r'elation' therewith at each end, a central adjustable support for the abrasive member ends thereof, a motor mounted on the base having a shaft at a right angle to the direction of reciprocation of the abrasive member, a gear on the shaft, a gear mounted on the base, and a pitman connection between the ear and the abrasive member, said cover ousing the mechanism and being provided with a hand hold to permit manipulation of the device.
2. In a device of the character described, an abrasive member comprising a reciprocable bar, a'flexible member'secured thereto at each end and in spaced relation therewith, a central adjustable support for the flexible member adapted to sustain and to flex the same, an abrasive-strip secured to the under surface of the said member, a spring clip member for securing the abrasive strip thereto and a releasing dog for each clip carried b ln-testimony whereo I sign this specification.
' JOHN reciprocable the said member.
and a member secured in spaced
