Application ledvNovember 3, 1917. Sera1No.200,188.
To all who/m 'it may concern Be it known that l, LAWRENCE J. Fox, a citizen of the United States, and resident of the borough of the Bronx, in the city, county, and State of New York, have invented a certain new and useful Cloth.- Drilling Machine, of which the following is a specification.
The present invention relates to cloth drilling machines, particularly to such machines intended for drilling or boring holes through a plurality of thicknesses of cloth which have been previously shaped by a cutting machine, although this is not necessary, the boring of the holes being for the purpose of indicating the position of pockets or the like, which are to be sewed to the cloth. through the cloth with a nail'as heretofore used, would not ordinarily provide a permanent marking, as the hole formed would close immediately after the drill is -withdrawn. The present embodiment of the invention proposes to rapidly revolve the drill as it is forced through the cloth, so that the friction produced serves to burn Athe hole permanently.
It is an object of the present embodiment of the invention to provide a machine with which holes may be bored and burned into the cloth accurately and in a convenient manner, requiring thc use of onlyv one hand,
- so that `the other hand may be otherwise employed. To this end, I propose to provide a machine having a slidable base, which may be engaged beneath the layers of cloth, and which will limit the movement of the needle after it is bored through thecloth, so that it cannot engage the table and drill a hole therein. Other objects are simplicity of construction, and facility of operation, permitting of accurate control of the boring needle with one hand, and without requiring that the hand be moved from the handle. A further object is an even disposition of the downward pressure exerted upon the needle during the boringl operation, so that an accurate boring of the cloth results. y Y
lVith these and other objects in View, an embodiment of my invention is shown in the accompanying drawings, and this embodiment will be hereinafter more fully described with reference thereto, andthe invention will be finally pointed out in the claims.
TheJ mere drilling of a hole,
In the accompanying drawings:
Figure l is a side elevation of an embodiment of my invention, showing the same in fulllines in its position previous to boring. holes through the cloth, and in dotted lines in its final position, the dotted line position also indicating its normal position when not in use;
Fig. 2 is a plan view of the same;
Fig. 3 is a sectional view of the base portion of the device; and
VFig. l is 'a detail yfront View of the base and Asupporting post. y y
Similar' reference characters indicate corresponding parts throughout the several gures of the drawings.'
Referring to the drawings, and moreA particularly to Fig. l and 2 thereof, the present embodiment of my invention, which is shown by way of exampleonly, comprises a base 7 bent downwardly at its marginal portions as at 7a and provided in spaced relationat its under side with rollers 8 rotatable upon shafts 8a journaled in the side portions of the base. l The base is preferably of the shape shown in Fig. 2, being straight at its forward edge and rounded at its rear edge, and is provided in the forward portion thereof with a flared opening 9.
The drawings represent the preferred embodiment of this invention. A movable base plate 7 isl freely traversabl'e over a work table and hasta thin edge 7a adaptedto slide under'a stack of cloth to be bored. This plate preferably is of the shape shown in Fig. 2, being straight along its forward thin edge v7% and rounded at its rear end. lt is preferably constructed with a downward marginal flange?d which is beveled at the forward endto form the thin edge '7a. The base in its flanged form is also provided with rollers 8 disposed in spaced relation on its underside on shafts 8a journaled in the side flanges of the base. The base plate is provided in its rear portion with a threaded socket 7b and near its thin or beveled edge with a flaring slot 9.
A post 5 is fixed to the base. This post may be detachable and in its preferred form it is provided at its lower end with a screwthreaded tang V6 which engages the socket 7b. This post is preferably angular and hollow in Vits upper portion and provided in one side in said upper portion ywith a vertical guide slot l2. A slot l2 is provided vso in the post 5 to accommodate the member 4L in its downward movement.
At the outer end of the handle 2 there is provided a bracket 2b, to which there is secured by means of rivets or the like 2c, a vertically disposed motor l. Current is supplied the motor through the wires la, and is controlled by means of a switch ll, provided in the bracket 2b, in such position, that it may be conveniently operated by the thumb of the hand engaging the handle 2. This switch is preferably of the well known push type, thc same being turned on, by pushing in one direction, and off, by pushing in the other' direction.
A drill head lb is iixedly secured to they shaft of the motor, and the drilling needle l() is secured to the said drill head. It will be understood that the same may be readily removed and sharpened or replaced, or a longer needle placed therein for the purpose of drilling an interior hole in the cloth, as will be hereinafter more fully pointed out. The needle l0 is in direct alinement with the hole 9 of the base, and when the apparatus is in the dotted line position shown in Fig. l, the point of the needle passes through the hole, but is prevented from further downward movement by a stop 5iL provided in the post 5, and which limits the downward movement of the support 3 and the parts carried thereby.
The operation of my drilling machine is as follows: The sliding base 7 is engaged beneath the lowermost layer of the layers of cloth 14, these layers of cloth being in practice, about eight inches high. The needle l0 is placed upon the point of the uppermost layer at which it is desired to drill a hole. Thereupon the current is turned on by the thumb pressing the switch l1, and the drill is pressed down by pressure being exerted upon the handle 2. The needle is .preferably first engaged with the cloth before the current is turned on, so that the same will not be disturbed from its proper alinement by centrifugal force. The boring is continued until the apparatus is stopped by engagement of the support 3 with the stop 5a. In this position, after all of the layers of cloth have been drilled through, the point of the needle is disposed in the opening 9 of the base.
The machine, it will be seen, is absolutely steady during the drilling operation, being supported directly upon the cutting table, and as one hand is free, the same may be utilized for holding down the cloth. Also, as the handle is supported at this outer end by the brace 4;, great pressure upon the same will not tend to change the alinement of the needle, so that an absolutely straight hole is bored. This is very important, as a slight change of the position of the needle will cause the hole to be bored in a different position in the lower layers of the cloth than in the upper layers. Except in the case of an interior hole being bored in the cloth, it is not necessary to lift the same from the table, and with the rollers 8 'it may be readily slid to any .position desired.
Vhere an interior hole is to be bored, the apparatus is placed upon the upper surface of the layers of cloth, and a longer needle is secured in the drill head, this needle being` of such length that it will bore a hole through the cloth beneath the base 7. The cloth at any interior point forms a very substantial support for the device, so that there will be no danger of the same becoming unsteady.
I have illustrated a preferred and satisfactory embodiment of my invention, but it is obvious that changes may be made therein within the spirit and scope thereof, as defined in the appended claims.
I claim:
l. A cloth drilling machine comprising a movable base plate freely traversable over a work table, and having a thin edge adapted to slide under a stack of cloth to be bored, a post fixed to said base plate, a vertically movable support mounted on said post, a motor carried by said support, and a vertically disposed drilling needle operated by said motor.
2. A cloth drilling machine comprising a movable base plate freely traversable over a work table, provided with rollers on its underside and having a downward beveled flange adapted to slide under a stack of cloth to be bored, a post fixed to said base plate, a vertically movable support mounted on said post, a motor carried by said support, and a vertically disposed drilling needle operated by said motor.
3. A cloth drilling machine comprising a movable base plate freely traversable over a work table and having a thin edge adapted to slide under a stack of cloth tobe bored,
a post fixed to said base'plate, a vertically movable support mounted on said post, a
motor carried by said support, and a verti-v cally disposed drilling needle operat-e-d by said motor, said freely traversable base plate having a needle slot opposite said drilling needle.
In testimony that I claimthe foregoing as my invention I have signed my name in presence of two subscribing witnesses.
