A suitable shoulder is provided on the pin near the nail engaging end 15 thereof and preferably takes the form of an annular notch or groove for the purpose of engaging the edge of the opening 28 in retaining finger 25, when the pin is substantially withdrawn from the bore 11 of the barrel and when the retaining member is in binding engagement with the pin, as will be readily understood, thus reventing accidental withdrawal of the pin f r o'm the barrel. 1

This construction possesses another ad vantageous feature, due to the resiliency of the finger 25, in' cushioning to some degree the blows of the hammer on the head 16of the driving pin, when the latter reaches a point near the upper end I) of the barrel, thus offering considerable resistance to any blow which would tend to drive the head 11 against the end I) ofthe barrel and mar the woodwork against which the end a of the barrel may,

engage. Suitable indicating marks 18 are provided on the driving pin 14 to co-operate with the edge of the opening 28 to indicate the position ofthe nailengaging end 15 of the driving pin 14.

In some instances the thumb 29 may be eliminated, and the pressure of the handle of theuser in grasping about thebarrel 10 will cause the edge of the opening 28 to bind against the pin, orvice-versa.

In Figures 4 and 5 is shown a modified frictional means engaging the pin 14. This modified means comprises a piece of resilient material, bent to form a resilient loop 31, as

prising a barrel, a driving pin slidable within the barrel, a resilient spring loop mounted on the barrel at the end thereof through which said pin is inserted to normally exert frictional pressure against the side of the pin to hold the same in adjusted positions in the barrel, and means for retaining said loop in position.

2. A tool of the character described comprising a barrel, a driving pin slidable within the barrel, a resilient spring loop mounted on the barrel at the end thereof through whichsaid pin is inserted to normally exert frictional pressure against the side of the pin to hold the same in adjusted position in the barrel, and a removable cap holding said loop in position on said'e'nd of the pin.

clearly shown, disposed in a thimble-capl member 32 having a central opening therein 33. The cap is threaded or otherwise se-' Y cured on the end I) of the barrel and the pin 14 passes through the opening 33' and through thespring loop 31. V The ends at andy of the loop member are bent upon themselvesto engage the side walls of the cap to produce a resilient contraction in the loop 31 which is designed to be of less diameter than the diameter of the pin, and thereby partially obstructs the opening 33 in the cap and exerts a, frictional bindingpressure on the side of the pin. In this form of theinvention the groove 30 is used on the pin with which the loop 31 will engage and prevent withdrawal of the pin from the barrel.

From the above it will be obvious that a very economical and efficient means has beenprovided for frictionally binding the driving broken.
