NAILING MACHINE Filed Dec. 7, 1953 2 Sheets-Sheet 2 III INVENTOR. ALBERT A. APPELL larly to hand tools or the United States Patent '25845625' NAILING MACHINE- Alhert A. Appell, North Hollywood, Calif. qApplication December 7, 1953, SerialrNo. 396,367 3 Claims. (21. 1+6) This. invention relates to machinery and more particugeneral class known as mechanical drivers, and particularly to nail drivers which operate mechanically and under the control of but a single operator. The invention has, among its objects, the production of means of the kind described that is simple, durable and compact in structure, inexpensive to make, manufacture and operate, dependable and eflicient in use and service and convenient to handle.
An object of the invention is to provide a simple, practical and eflicient nail driving machine that may be operated on either electrical or pneumatic power and which is adaptable for constant and continuous use and rough handling.
Another object of the invention is to provide a more satisfactory nailing machine that incorporates ,novel features for feeding nails from a source of supply to the position to be struck by the hammer element.
An additional object of the invention is to provide in a machine of the character described novel means for positioning the nail prior to being struck by the hammer element.
Other and additional objects and advantages Will appear and be brought out more fully in the following specification, reference being had to the accompanying drawing wherein:
Figure 1 is a side elevation view of a nailing machine incorporating the invention.
Figure 2 is a partial end elevation view of the same.
Figure 3 is a sectional view taken along the line 33 of Figure 1.
Figure 4 is a fragmentary view of the hopper link mechanism shown in Figures 1 and 3.
Figure 5 is a partial view in sectional elevation of the structure shown in Figure 1 showing the parts after a nail has just been driven home in a workpiece.
Figure 6 is a sectional view taken along the line 66 of Figure 5.
Figure 7 is the sectional view 7-7 of Figure 5.
Figure 8 is the fragmentary view showing the structure also shown in Figure 5 but with a nail in position to be engaged by the hammer.
Figure 9 is a separate view of the nail selector means shown in Figures 5 and 6.
Referring more particularly to the drawings the numeral 1t} designates generally a frame or body which is elongated and extends upwardly from a base 11 which may include a stirrup 12., the body having a bore 13 in which is positioned the hammer piston 14 which is suitably driven by the reciprocating driving element 19 of a pneumatic or electric hammer generally designated 15.
Body has a side extension portion 16 which provides pivots 17 to which pivots are secured to one end of a hopper frame 18 on which is mounted a hopper 20 for holding a plurality of nails. Hammer driving element 19 is carried by a casing structure 21 which has a pair taken along the line of sidev extensions 22 from whichextend downwardly a tion shown in Figure 1 to thatshown inFigure 5, the nail .pair of guide rods tension 24 happen 20 willbe tilted'downwardly. A shield 20a is positioned in hopper ming. of nails in-the slot, 7 Side extension 16 is formed aboveslot 27 to prevent jamwith a slot and body .111 is hollowed forming a passage 29, the lower portion of which is inclined at 30 and is formed with a pocket or recess 31, the lower portion of which is inclined at 32 to provide a seat for a nail restraining roller 33. The lower end of bore 13 is enlarged, in which enlargement is a sleeve 34, the upper portion of which is cut away at the right side and is formed with an aperture 35, the lower edge of which is turned upwardly to provide a seat for roller 33, thus permitting the roller to extend partially into the sleeve but permitting space for the shank of a nail, the head of which rests on the upper curved portion of the roller.
When the hammer body 15 is raised to the position shown in Figure 1, the ring 39'is rotated by the spring 42 back to the position shown in Figure 6, and the nail which has entered slot 43 is shifted out of sleeve 38 and dropped downwardly in passage 29 to the position shown in Figure 8, ,and is arrested by roller 33.
The operation of the invention should be clear from the foregoing description. Figure 5 shows the condition of the parts with a nail just driven home in a workpiece, and upon the hammer unit 15 being raised to the position of Figure 1, one or more nails are delivered from the hopper 20 to the guideways 37, and'the nail in the selector ring is then dropped downwardly to the arresting roller 33 in readiness for the next hammer stroke. When the hammer body 15 is lowered and hopper 20 is tilted downwardly as in Figure 5, ring 39 is rotated by arm 44 and a nail from passage 36 enters ring slot portion 43a. This can be repeated rapidly and effectively as long as nails are supplied by the hopper to the hammer body.
