SECIFIGATION forming part of Letters atent No. 694,854, dated March 4, 1902.

Application led July l2, 1901.

To all wiz/0771, it 1mi/,y concern:

Beit known that I, EDWARD HANNEE, aciti- Zen of the United States, and a resident of Ridgway, in the county of Elk and State of Pennsylvania, have invented a new and Improved Tack and Nail Puller, of which the following is a full, clear, and exact description.

This invention relates to a class of implements employed for the removal of tacks and nails from the material in which they have been driven, and has for its object to provide a novel andvery elicient device of the character indicated which is inexpensive, practical, and convenient to use, which will reduce the labor incident to the extraction of tacks or nails, greatly Ireduce injury tothe material from which the tacks or nails are extracted, and avoid injuryto the hands which ordinary means sometimes entails.

The invention consists in the novel con-` struction and combination of parts, as is hereinafter described, and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in whichA similar characters of reference indicate corresponding parts in all the gures.

Figure lis a plan View of theimprovement. Fig. 2 is a partly sectional side view of the same. Fig. 3 is a sectional side View showing a slightly-changed construction ofthe working parts ot the tack-puller, and Fig. 4 is a side View of the device arranged forvpulling nails.

In Figs. 1, 2, and 3 ot lthe drawings, that represent the invention as constructed for pulling tacks or small nails, 5 5 indicate Atwo half-sections of the handle. The handle-sections 5 are each recessed upon one side, forming equal longitudinally-extending cavities therein, and at the forward ends of each of said half-sections a rectangular formation 5fL is provided, which portions 5iL when joined together constitute av box-like frame for the support of the working details of the device. The handle 'may also be made solid or in one piece, if preferred. From the box-frame 5fL the handle-sections curve upward and laterally, as indicated in Figs. 1 and 2, and these portions are joined together at their free edges and held as one piece by the screws or Serial Nc. 63,009. (No model.)

rivets ct. The box-frame 5L is open at the front end and is apertured in its top Wall, as shown at h In', these openings affording free- 'dom for the insertion and operation of the peripherally-circnlar head-block 6. Rolling supports 7 7, which may be two or more, as preferred, are provided as seats for the curved lower edge of `the head-block 6, and, as shown construction a screw-cut shank d isextended from the rear end of they claw-foot and is adapted to screw into a threaded socket formed to receive it in the forward edge of the head-block, as clearlyvshown in Fig. 3. From the upper edge portionof the head-block 6 a lever 9 is extended upwardlyrand rearwardly, said lever passing through the opening h in the` top wall of the box-frame 5, which openingextends such an extent rearwardly as will permit a free movement of the lever and headblock in the box-frame. The lower side of `the box-frame -5n is preferably corrugated, as

shown at a in Fig. 2, which provision enables the holding of the implement in position for service when employed to pull tacks. At a suitable point above the transverse rollers 7 opposite slots e are formed yin the side walls of the box-framed, and in said slots trunnions g engage, which are alined projections from opposite sides of the head-block 6, at or near its center, or, it' preferred, a loose rolling pin may extend through the head-block .into said slots.

It will be seen that the described construction affords a double antifriction-support for the head-block 6, which by the vibratory movement of the lever 9 will be rocked upon the rollers 7, and by the engagement of the trunnions g or the rolling pin in the slot e the head-block and claw-foot S will be adapted to assume the different positions represented by full and dotted lines in Fig. 2.

In the use of the tack-puller the members of the handle 5 are grasped in one hand and the lever 9 taken in the other hand of the operator, who places the claw-foot 8 in engagement with the head of a driven tack that is to be lifted, the ylever 9 being fully elevated. The claw-foot 8, by manipulation of the handle 5, is held firmly against the under edge of the head of the tack it is to raise, and simultaneously downward pressure is exerted on the lever 9, which will cause the trunnions g or the rolling pin engaged in the slots e to move sufciently forward and cause the clawfoot 8 to embed itself securely under the head of the tack. The head-block then coming in contact with Ithe rollers 7 and downward pressure on the lever 9 being continued, the claw-foot will be caused to rock upward and forward, lifting the tack with ease, and without bending it, with greater certainty than is attainable by the use of the ordinary tackpuller.

In Fig. 3 the claw-foot, which is provided with the screw-shank d, may be readily exchanged if it becomes worn from use, or different sizes of the same may be substituted, as occasion may require. I have also shown in Fig. 3 bearing-balls 7, two or more of which may be employed, as preferred, and held loosely in pockets z', formed in the box-frame of the implement and afford antifriction-snp port for the head-block of the device, the operation in such case being similar to that already described. Y

In Fig. 4 the device is shown as adapted for use in pulling 'large nails from boxes. In this modification of the implement the clawfoot is somewhat elongated, and therefore is adapted to extend farther from the box-frame y lO, that in this construction is devoid of a handle extension. From the upper side of the head-block 6 extends the shank 6", which slidably engages within the hollow lower end of a lever 11, which is shown broken away, but which may be extended a suitable length for eflicient service. The box-frame l0 is diagonally and oppositely slotted, as at e, to receive the axially-extended trunnions g or a loose rolling pin, and a pin 7c projects laterally from the shank 6b,near its free upper end, into a longitudinal slot m, formed in the lower hollow portion of the lever l1 to pre'- vent said lever from being disengaged from the shank 6b. In operation the sharpened front edge of the claw-foot 8fL is firmly held against the under edge of the head of a driven nail that is to be extracted and is supported in position by the box-frame 10, the trunnions g or the rollingfpin being at the top of the slots e, whereupon the operator quickly and forcibly slides the lever 11 upon the shank 6", so as to strike the top of the shank 6b a smart blow, which will cause the rolling pin or the trunnions g to move forward, causing the claw-foot to be embedded beneath the head of the driven nail, so that a downward rocking ymovement of the lever 11 will extract the nail in an obvious manner. It will be seen that in case the package to be opened by the improved nail-puller is bound byiron straps or bands the claw-foot 82L may be readily driven beneath such bands, and by rocking the lever l1 downwardly the nails that have penetrated the box material may be readily withdrawn.

Changes in minor construction yand details may be resorted to without affecting the principles involved in my invention.

Having described my invention, I claim as new and desire to secure by Letters Patentl. A tack-puller, comprising a box-frame, a handle thereon, antifriction-bearings held in the box-frame, a head-blockrockably held in the box-frame and supported on the antifriction-bearings, a claw-foot extended for- Wardly and downwardly from the head-block, and a lever projected from the head-block.

2. A tack-puller, comprising a-box-frame, an upwardly and laterally bent handle extended from one end of said box-frame, which frame is open at the opposite end, two spaced antifriction-bearings in the box-frame, a circularly-edged head-block seated upon the antifriction-bearings, diagonal slots in the vbox-frame, trunnions on the head-block en-v gaging said slots, and a lever extended from the head-block through a slot in the upper side of the box-frame.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDlVARD IIANNER.
