HAND LAsTiNjG-'Toon SPECIFICATION forming part of Letters Patent N o. 658,766, dated 'October 2, 1900.

Application filed December 16, 1899. Serial No. 740,547. (No model.)

To all whom it may concern.'

Be it known that I, NAPOLEON DUssAULT, a subject of Her Majesty the Queen of Great Britain, residing in the city and district of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements inl-land Lasting-Tools; and I do hereby declare that the followingis a full,olear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hand lasting-tools; and its object is to provide a tool of this character which is simple in construction, of few parts, eifective in operation, and which may be manufactured at a moderate cost.

To these ends the invention consists in a hand lasting-tool constructed substantially as hereinafter illustrated and described and dened in the appended claims.

Referring to the drawings, in which similar letters of reference indicate similar parts, Figure l is a view in perspective of a hand lasting-tool constructed in accordance with this invention. Fig. 2 is an elevation thereof, the parts being in the position assumed prior to driving the nail.

ed have generally been very complicated,- comprising many parts and entailing great- InV the type expense in their manufacture. shown in the patent to Frechette, N o. 594,241', on which this invention is an improvement, not only are the objections above noted apparent, but there exists the further objection that in the event of the nail' being broken or of failure to be properly fed to the plunger it is necessary to take the tool apart in order to bring the nails down into their op- 5o erative position, thus necessitating a serious Ashown in Figs. 4 and 5.

Fig. 3 is a viewV similar to Fig. 2, showing the opposite side of lloss of time and involving considerable trouble and inconvenience. In the tool about to be described all of these defects and objections are obviated and a hand lasting-tool provided which in the event of the failure of the nails to be properly fed to the plunger or of breakage of the same does not need to be taken apart, thus saving time and trouble, in addition to the advantages of simplicity of construction and operation and reduced cost of manufacture.

In the drawings, A and B represent two levers suitably pivoted together and pro vided with handles A and B' and jaws A2 and B2. The lever B has alug b on its under side, having a roughened face. The lever A is provided at the outer end with a frame `A3, in which is formed an opening a, extending therethrough from top to bottom. In the upper portion of the frame A3 is fixed a plug o', which has its sides inclined from top to bottom and is provided in its upper portion with a passage a2 for the nails, as clearly The passage a2 communicates with the Opening a, and a suitable leaf-spring o3 is secured to the upper portion of the plug u.' and bears at its lower portion against the inclined side of said plug.

The construction and operation ofthe parts above described are substantially'the same as those disclosed in a companion application, Serial No. 739,881, in which -is shown a modified construction of the nail-driver.

l The outer portion of the frame A3 is provided with an upwardly-extending lug a4, in which is formed a vertical socket a5 for the :reception of the guide-rod d5, forming a portion of the plunger D. The upper portion of the lug 034 is provided with a rearwardly-extending arm 0,6, in which is fixed an upwardlyprojecting guide-rod n.7, which engages an opening in an oifset as, formed upon the plunger D. Upon the opposite side of the upper portion of the lug a4 extends a bifurcated arm a9. Upon the side of the plunger opposite the offset as is formed an extension having an opening d10, which is preferably provided with straight sides and in which is loosely mounted the feed-rod carrier D', the screw-rod ct" forming the supporting connec- IOO tion for said carrier, said screw-rod being removably secured in said extension to enable the parts being readily taken apart.

The carrier D' extends downwardly and is guided in the bifurcated arm ai against lateral movement. The lower end of the carrier is split, forming a spring-clamp d, which is provided with a suitable binding-screw. A threaded perforation d2 is formed in the lower portion of the carrier D and communicates with open-sided channels (Z2, formed upon the adjacent faces of the clamp d'. A feed-rod or nail-driver D2 is threaded in the perforation d2 and is seated in the grooves d2, the lower end of said feed-rod projecting beyond the edge of the carrier D and eX- tending into the opening a of the frame A2. The extremity of the feed-rod D2 is suitably sharpened for cutting off the nails.

The body portion of the carrier D' below the feed-rod D2 is downwardly inclined, forming an inclined bearing-surface d", which is adapted to engage in its downward movement with a corresponding inclined bearing-surface d, formed on the lower portion of the guiding-bracket E. 'lhe bracket E is constructed with the spaced sides e', which embrace the sides of the frame A2, and are rigidly secured thereto by suitable screws threaded into the sides of the frame and the upper portion of the jaw A2. The lower portion of the guide-bracket E extends downwardly to within a short distance from the extremity of the jaw A2, but far enough therefrom to permit the end of the carrier and the feed-rod to pass to the limit of their stroke.

A suitable spring D3 is secured at its lower end to the carrier D and at its upper end to the lug a4, as shown in Fig. 2, which tends to retract the plunger when released and also holds the feed-rod in proper position within the opening a of the frame A3. If desired, a spring D3 may be provided upon each side of the frame, in which case one of the springs D3 may be mounted as shown in Fig. 3. A suitable spring D4 may be employed to open the jaws A2 B2. dlodesignates a stop adjustably carried by said carrier D, said stop serving to limit the retraeting movement of the carrier.

The lever A is provided at a suit-able point on its upper side with a lug f, to which is rotatably secured a reel F. The lasting-nails f' are formed continuous with each other and are wound upon the reel F.

In operating the improved lasting-tool above described the lasting-nails are passed through the perforation in the plug a and down between thc inclined sides thereof and the leafspring c2, whereby the nails are held in their operative position ready to be fed to the Work. The nails are then passed down through the openings a of the frame A2, between the point of the feed-rod D2 and the inner face of the jaw A2, said face forming an anvil toward which the nail-driver is carried, as clearly shown in Figs. 4 and 5. The parts are now in the position shown in Fig. It and the tool is ready for operation. The lever-handles A and B are grasped with one hand and the jaws A2 and B2 closed upon the work. The plunger D is then forced downwardly, carrying with it the carrier and the feed-rod, the sharp point of which engages the nail just back of the head and forces the same into the work. When the plunger reaches the guidebracket F, the inclined face of the plunger engages t-he inclined face of said bracket and the feed-rod is forced inwardly toward the frame A3 and against the nail with increasing force until at the end of the stroke the cuttingpoint of the feed-rod severs the lasting-nail, which has been driven up to its head in the work, the parts assu ming the position shown in Fig. 5. Upon releasing the plunger the carrier is returned to the position shown in Fig. 4 by means of the spring or springs D2, the point of the feed-rod sliding back above the head of the next nail to be driven. A suitable stop-plate A4 is pivoted to the frame A3 and adapted to engage a lug on the plunger to lock the parts in their raised position when desired.

As will be seen by referring to the drawings, the plunger has a true reciprocating movement within the frame A3, by means of which there can be no binding of the parts; but the carrier D, which is operated by the movement of the plunger, has no such true movement, it being capable of being oscillated on its pivot, as heretofore described, and while said carrier is connected to said plunger, yet it is connected thereto and extends from a point away from the longitudinal center of said plunger. This construeiion enables me to provide a feed-bar or naildriver which has its longitudinal center eX- tending substantially in a direction corresponding to the line of movement assumed during the severing operation. In other words, the pressure placed on the nail-driver during its severing operation is exerted in the direction of its longitudinal center in a manner similar to the action of a chisel, thus eliminating to a great extent the liability of the cutter becoming broken, which would be the case where the cutting movement is at substantially right angles to the longitudinal center of the cutter. I am therefore able to make use of an extremely small and light cutter and am also able to make such cutter adjustable and removable within its carrier without the loss of strength. It also enables t-he use of a cutter which can be readily sharpened.

Another feature of my construction consists in the use of the stop d10. It being apparent that the feed-bar will be held yieldingly against the nail-strip by the springs D2, it will be seen that any movement of the plunger will cause the feed-bar to move along the nail-strip until contacting with a nail- IOC IIO

head, and further movement will feed the nail-strip forward and drive the nail. As it may be necessary to use nails of different lengths, it would be possible if the movement ofthe plunger were absolutely fixed thatin the case of small nails there would be a tendency of the feed-bar feeding two nails instead of one. This tendency is eliminated by the use ofthe adjustable stop,whicl1 limits the upward movement of the plunger, and

therefore prevent-s the feed-bar 'passing to a point above the second nail-head or the nailstrip, but does not restrict in any manner the feed and severing movement of the feedbar, the latter movement always terminating at the same point.

It will be seen from the construction above described that if a nail breaks off above the feed-rod it is only necessary to again raise the plunger to its full height, whereupon the feed-rod will engage and drive down the next nail, or if a defective nail is engaged it is only necessary to operate the plunger and cut until a perfect nail is reached. Hence it will be seen it is never necessary to remove the parts of the tool to insure the proper feeding of the nails or remove broken or bent nails.

While I -have herein shown a preferred form of carrying my invention into effect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within the spirit and scope of my said invention.
