Abstract
An automatic nailing device employs a cartridge of nails which are supplied in series beneath a spring driven hammer. An electric motor charges the spring-driven hammer after each operation.
Description
This invention relates to an automatic and portable nailing device, and more specifically relates to a novel nailer which is electrically powered.
Automatic and portable nailers are well known for use at construction sites and the like. These devices, conventionally, are pneumatically powered. It would be desirable to have electrically operable nailers since it is more convenient to bring electrical power to a site than to set up the compressors needed for a pneumatically operated device. Moreover, an electrically operated device will be more easily portable than a pneumatically operated device.
In accordance with the invention, a portable automatic nailer is provided with a spring-operated hammer which can strike nails automatically supplied from a conventional nail supply cartridge. An electric motor is built into the portable nailer and acts to charge the spring mechanism to a spring-compressed position after the nailer is operated to drive a nail from the nail supply cartridge. A novel ball latch and ball driving arrangement are operated from a manual trigger. The operation of the trigger releases the ball latch to permit the spring-charged mechanism to release the stored energy therein and drive a nail. Release of the trigger causes the electric motor to recharge the spring and the latching of the spring in its charged position.

FIGS. 15 to 17 are schematic diagrams of the control linkages of FIG. 1 in the firing, recharging and reset positions respectively.
Referring first to FIG. 1, there is shown an electric and portable nailer which generally comprises a main hammer housing 20 which has a handgrip 21 secured thereto. Handgrip 21 contains a movable plate 22 which actuates microswitch 23 when a user picks up the tool. An electric motor housing 24 is connected to housing 20 and contains a suitable a-c motor 25. Motor 25 is energized from a flexible cord (not shown) which enters housing 24 and is turned on when microswitch 23 is actuated by plate 22.
A shaft 26 extends from motor 25 and is secured in bearing 27 in the lower portion of housing 20. A conventional nail cartridge 28, which slidably supports nails and delivers them one by one to cartridge end 29, is appropriately secured to housings 20 and 24. Cartridge 28 contains nails, such as nails 30 and 31, as by slidably supporting the nail heads in a suitable channel. Nail 32 is shown in a delivered position, awaiting a hammer blow.
A manual trigger 33 is then provided to actuate the hammer blow.
The upper portion of housing 20 contains a powerful compression cartridge 34 which is carried in a retaining cup 35. Cup 35 is then connected to hammer member 36 which consists of a threaded section 37 and elongated ram or hammer section 38. Note that a latching shoulder 39 (FIGS. 1, 10, 11 and 12) is formed between members 37 and 38. The bottom end of hammer 38 is slidably received in cylindrical section 40 at the bottom of housing 20.
The charging mechanism, for charging, or compressing spring 34, includes rotatable charging sleeve 50 (FIGS. 1, 10, 11 and 12) which is fixed to bevel gear 51 (FIG. 1) which is driven by cooperating gear 52 on motor shaft 26. Gear 51 and sleeve 50 are suitably rotatably mounted by bearings schematically shown as bearings 53, 54 and 55 (FIG. 1). Note that sleeve 50 rotates so long as the user holds the portable nailer and holds plate 22 against microswitch 23. Note further that sleeve 50 is fixed against axial movement.
The upper end of sleeve 50 then contains apertures for receiving a series of drive balls and a series of latching balls. Thus, as best shown in FIGS. 10 to 14, sleeve 50 contains three apertures 63, 64 and 65 which are disposed in a plane parallel to the plane of the pitch of the screw 37. Apertures 63, 64 and 65 then receive balls 66, 67 and 68 which have a diameter such that the balls will fit partly into the thread forming screw 37. Therefore, when sleeve 59 is moved down to the position of FIG. 12, rotation of sleeve 50 in a clockwise direction (as seen from the top of FIG. 12) will cause the upward movement of screw 37 and hammer 38.
Sleeve 50 also contains a plurality of openings 70, 71 and 72 (FIGS. 10, 11, 12 and 14) which are in a plane perpendicular to the axis of member 36, and which receive balls 73, 74 and 75 respectively. Balls 73, 74 and 75 have a diameter greater than that of balls 66, 67 and 68 and are adapted to latch under shoulder 39 when the apparatus is in the position of FIG. 10.
Note that any desired number of balls can be used in place of the three balls shown for sets 66, 67 and 68 and 73, 74 and 75.
The operating linkage connecting trigger 33 to sleeves 56 and 59 is best shown in FIGS. 1 and 4 to 9. These linkages are suitably supported relative to housing 20, and include elongated plate 80 which slidably receives elongated channels 81 and 82 at its outer edges. Typically, channel 81 is shown in FIGS. 8 and 9.
As shown best in FIGS. 4 and 5, the outer end of trigger 33 is pivotally connected to the upper end of member 80 by a pin 83. An intermediate point on trigger 33 receives toggle link 85 by pin 86. The opposite end of link 85 is pivotally connected to the upper ends of channels 81 and 82 by pin 87.
The lower end of plate 80 is then connected to a yoke 90 by pin 91 while the lower ends of channels 81 and 82 are connected to an identical yoke 92 by a pin 93 (FIGS. 1, 3, 4 and 5). Each of yokes 90 and 92 are pivoted on fixed pivots 95 and 96 respectively (relative to housing 20), and capture a compression spring 97 between them. Each of yokes 90 and 92 have the shape generally shown in FIG. 3 for yoke 92 and have generally Y-shaped arms which terminate in rollers, shown as rollers 100 and 101 in FIG. 3, which are captured in channel 58 in disk 57. A similar arrangement is provided for yoke 90, with its rollers engaging channel 62 of disk 61.
Note that the general arrangement described above is shown schematically in FIGS. 15 to 17.
It is now possible to describe the operation of the device, with particular reference made to FIGS. 1, 10 to 12 and 15 to 17.
Assume first that the spring 34 is charged and latching balls 73 to 75 are latched under shoulder 39, holding hammer 36 up and holding the spring 34 charged. The operator is holding the tool so that motor 25 rotates gear 51 and thus sleeve 50. Sleeve 56 is in its upward position (FIG. 10), urging balls 73 to 75 under shoulder 39 and sleeve 59 is in its upward position of FIGS. 1 and 10, so that driving balls 66 to 68 are moved outwardly by the rotation of sleeve 50 and out of engagement with screw 37. In addition, a nail 32 is in driving position at the bottom of the device.
To fire the device, the operator pulls trigger 33, rotating it counterclockwise about pivot pin 83. Note that this movement extends the biasing spring 111 (FIGS. 1, 15, 16 and 17). As shown in FIGS. 11 and 15, this movement causes yoke 92 to rotate counterclockwise to lower sleeve 56. This enables latching surface 39 to cam latching balls 73 to 75 outwardly to release hammer 36. Hammer 36 then moves downwardly, discharging the energy stored in spring 34 to apply a hammer blow to nail 32 to drive the nail. Note that a shock-absorbing ring 110 receives the bottom of cage 35 to stop its downward stroke.
After the nail has been driven, trigger 33 is released as shown in FIG. 16. This causes linke 80 to move up and yoke 90 to rotate counterclockwise (under the influence of spring 97). This motion of yoke 90 moves sleeve 59 down to the position of FIGS. 12 and 16 to force drive balls 66 to 68 into the threads of threaded member 36. The rotation of sleeve 50 then causes balls 66 to 68 to drive threaded shaft 37 upwardly relative to sleeve 50, thereby to compress spring 34. Once the latching surface 39 clears the top of balls 73 to 75, these balls are forced to move under surface 39 by sleeve 56 which is being biased upwardly by spring 111. Thus, once the main spring 34 is charged, both yokes 90 and 92 rotate to the reset position of FIGS. 10 and 17 to latch the hammer 37 in position and to move sleeve 59 upward to release balls 66 to 68 from their driving relation with threaded portion 37 of the hammer. The system is now in position for the next automatic hammering operation by operation of trigger 33.
Although there has been described a preferred embodiment of this invention, many variations and modifications will now be apparent to those skilled in the art. Therefore, this invention is to be limited, not by the specific disclosure herein, but only by the appended claims.
