THOMAS G. BLADEN, OF VANDERGRIFT, PENNSYLVANIA.

TACK-PULLER.

SPECIFICATION forming part of Letters Patent No. 705,554, dated July 29, 1902.

Application filed October 8. 1901. Serial No. 78,013. (No model) To all whom it may concern:- Be it known that I, THOMAS G. BLADEN, a citizen of the United States of America. residing at Vandergrift, in the county of VVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Tack-Pullers, of which the following is a specification, reference being had therein to the accompanying drawings. This invention relates to certain newand useful improvements in tack-pullers, and has I for its main object to construct a tack-puller with a jaw to engage the tack and a pivoted gripping-point to engage the floor and act as a fulcrum block while the puller is being used.

The puller comprises,essentially,two parts, the handle or lever having the pulling-jaws at one end and the gripping-point pivoted to the lever with a spring connected thereto, so as to hold the same normallyin one position, and the specific construction will be hereinafter more clearly described and then pointed out in the claim.

In describing the invention in detail reference will be had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference will be employed for designating like parts throughout the different views, in which Figure 1 is a side view of my improved tackpuller, showing how the same is engaged with the tack for pulling the latter. Fig. 2 is a top plan View thereof. l

I aim with my invention to provide means whereby the tack may be pulled from position without bending the same, so that it may be reused, and to this end provide a lever 1, the upper end of which forms the handle 2 and the lower end of which is provided with claws 3, between which the tack tis engaged. The lever is curved into substantially the form of an S, the bow 5 thereof engaging the floor. Pivotally secured to this lever 1, just above the shortbow thereof,is a gripping-point 6, which is adapted to engage with the floor and is held normally inthe position shown in Fig. 1 by a coil-spring 7, connected to the gripping-pointand to the lever. The pivoted dog 6 has a pair of lugs 6 6, formed integral therewith, for the reception of the lever-pin 6", passing through both lugs and the lever.

My improved device is used in the manner shown in Fig. 1, the gripping-point 6 being engaged with the floor after the claws have been engaged with the tack. When in this position, pressure upon the handle 2 will cause the claws to be raised in a vertical line, as the gripping-point prevents any forward movement of the claws due to sliding of the puller upon the floor, and the tack is consequen tly withdrawn from the floor without bending. The spring 7 serves to retain the dog or gripping-point normally in position to engage with the floor when it is desired to use the tack-puller.

Attention should be called to the location of the engaging gripping-points with relation to the point of pivot of the dog 6, which pivotal point is slightly to the front of the gripping-points when the same is in a position previous to the pulling of the tack. Thus there results two movementsnamely, the movement of the lever about the fulcrum 6 and simultaneously therewith the rearward movement of dog 6 and the said lever, whereby a direct vertical pull is exerted upon the tack.

In the practice of the invention it will be observed that slight changes could be readily made in the details of construction without departing from the general spirit of my invention.
