This invention relates to a paper drill designed for the purpose of drilling a hole through a of paper. Such drilling of holes is very desirable, particularly wherea large-number of sheets of paper are to be properly located with respect to each other and bound topaper should be in substantially exact alinement for the passage of posts used in paper binders between covers and over which the sheets of paper are placed.
The drilling of the holes through the` sheets of paper 1s accomplished by -*cutting disks consecutively through the sheets' of paper from the uppermost to the lowermost sheet. The drill is of a hollow type and the disks of paper cut from the sheets pass upwardly through the hollow drill. With my invention it is designed that the disks cut from the paper may be directed and thrown outwardly away from the drill when it is construction which permits and facilitates such action.
The invention consists of novel details of construction and arrangements of parts for the ends stated, as will be apparent on an understanding of the invention had from the following description, taken in connection with the accompanying drawings, in which,
Fig. 1 is a front elevation of the drill showing the same attached to any suitable drill spindle.
Fig. 2 is a longitudinal vertical section through the drill and,
Like reference characters refer to like parts in the diiierent figures of the drawings.
In the construction of the drill a cylindrical shank 1 is provided from which, at its lower end, the drill proper 2 extends. The Shank and the drill are made integral with each other from a single piece of metal. Both the shank and drill are bored lengthwise thereof and atvthe lower end of the plurality of superimposed sheetsand the holes through the sheets ofr drill 2, adjacent itspper portion, tapers outwardly and 1s somewhat larger than at the lower end, whereby the disks 5 when cut from the sheets of paper 6 located one over the other 1n a solid block may pass upwardly through the drill 2 and do not bind and resist upward movement.
.The shank 1, in a side thereof a short dlstance above the upper end of the hollow drill 2, has a recess of the form indicated at '.7 cut therein. This recess at its upper side lnclines downwardly and inwardly and its lower side is located a short distance above a horizontal ledge' 8 as shown. A rod 9 is inserted with a press fit'into the longitudinal opening through the shank 1. At its lower end it is cut at an angle making the edge 10 which is inclined both to the horizontal and vertical, as shown, while at each side of the edge 10 portions are cut away, as indicated at 11, to bring the lower end of rod 9 to a point and provide the' two angular faces 11 disposedsubstantially at right angles to each other.
The drill as thus made is adapted to be suitably connected to any drill spindle of a drill press, the upper end of the shank 1 being received within the chuck 13 carried at the lower end of the drill spindle 14. The block of sheets of paper 6 may be placed on any suitable support, indicated at 15 in Fig. 3, below the lower end of the drill and then the drill rotated and moved downwardly or the table carrying the block of paper moved upwardly with pressure sutlicient that the drill will pass through and cut the disks 5 from the consecutive sheets of paper in the block. The disks pass upwardly through the drill 2, having freedom of movement as they approach the upper end thereof and when they reach the lower end portion of the rod 9 with its angular faces 11 the disks are directed outwardly; and with the rotation of the drill are thrown outwardly by centrifugal force, keeping the drill clear of disks of paper which might clog the vdrill and prevent its effective operation. The construction described while of a simple character and one which is readily and easily made is very effective and has proven prticularly useful for the purposes. for which it is degned. 1
The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
I claim; A Y 1. A drill conprising a shank and a drill integnLwith and extending downwardl l0 from the lower end of the shank, xsaid dri and shank having axially alined lon 'tudinal openings therethrough, said sha having a reces-through one side thereof a short Vdistan' ce above e lpper end of g1; drilll comd ll municatingwi t e o m'ng ou v sai shank an drill, and ape rod securedgin the o Vin said shank havingA the lower end `thereocut in a plane located at an acute Y angle to the axis ofthe rod to -form a de- N fleeting edge inclined upwardly and outwardly toward the open side of said recess, and said rod at its lower end at each side Y of said deiecting edge having parts cut away on downwardly andinwardly inclined 85 planes meeting substantially at the lowermost point of said rod.
2. A drill comprising a shank and a drill integral therewith extending downwardly Yfrom the lower end of the shank, said drill 3Q an`d shankhavinglongitudinally alined openings therethrough with a common longitudinal axis, said shank, a short distance above the upper endof the drill, having a reee cut in one side thereof, the recess having a horizontal lower side, an upwardly and outwardly inclined upper side` and vertical inner sides at each sideof the opening in said shank, a rod formed at its ower end with an upwardly and outwardly l0 inclineddeflecting edge extendinginto said reee and located at an angle to the vertical and extending from the inner side of said reces upwardlyand outwardly toward the open "side of the recess, said rod also having deflecting surfaces at its lower end positioned at an angle to each other at each side of said inclined deilectin edge.
In testimony whereof ailix my signature.
VHERMAN D. MIELKE.
