Definitions

  • the impact blow receiving member is positioned in longitudinal alignment with the fastener driving element and moves in the same direction as the drive stroke of the fastener driving element when impacted.
  • the application of the impact blow serves to preposition the workpiece before the fastener is driven, to provide a quicker opening ofthe main valve means, to aid in the fastener driving operation and to dissipate recoil action.
  • Fluid pressure operated fastener driving devices have been available commercially for many years. The commercial usage of such devices has increased over the years and along with this increased usage the operating efficiency of such devices has also been improved.
  • Such devices conventionally include a fastener driving element which is moved through a drive stroke by a piston mounted within a cylinder.
  • a magazine structure is provided for receiving and supporting a supply of fasteners and for feeding a fastener from this supply into a position to be engaged by the fastener driving element during the drive stroke of the latter and to be driven thereby into a workpiece.
  • the present invention is based upon the principle that the fastener driving efficiency of a device of the type described can be still furtherimproved by effecting a mechanical movement ofthe main control valve from its closed position into its opened position in response to an impact blow rather than in response to change in pressure conditions resulting from the actuation of secondary valve means.
  • This improved efficiency is achieved by the'more rapid opening of the main control valve by means of an impact blow as distinguished from a change in air pressure conditions. It will be understood that source pressure will be more rapidly available to effect the drive stroke ofthe piston where the main valve is more rapidly moved into its fully opened position.
  • a fluid pressure operated device of the type described having means for rapidly effecting a mechanical movement of the main control valve into its opened position in response to an impact blow applied to an impact blow receiving member carried by the device.
  • the driving efficiency of a fluid pressure actuated fastener driving device can be improved sufficiently that the drive stroke will take place substantially simultaneously with the impact blow which is applied to initiate the drive stroke. Consequently, in accordance with the present invention, it is preferable that the initiating impact blow be applied to the device in a direction which is substantially the same as the direction in which the fastener is driven ⁇ Under these circumstances, the initiating impact blow aids in the fastener driving operation and has the effect of substantially reducing the recoil action heretofore experienced in prior art devices.
  • the principles of the present invention may be embodied in a device so as to constitute the sole means of opening the main valve to initiate the drive stroke of the piston, the present invention contemplates the application of these principles to existing devices in such a way that the operator is provided with an independent alternate means of actuating the main valve in addition to the conventional actuation means provided, as for example, fluid pressure actuation of the main control valve through secondary control valve means operated in response to digital movement of a trigger and/or in response to workpiece engagement ofa contact trip element.
  • a fluid pressure actuated device of the type described having means for mechanically moving the main control valve means into an open position to effect the drive stroke of the piston in response to the application of an impact blow to an impact blow receiving member carried by the device, which device also includes as an alternate means for opening the main valve, secondary control valve means through which the main control valve is opened in response to a change in air pressure conditions acting thereon.
  • FIG. 1 is a perspective view of a fluid pressure operated fastener driving device embodying the principles of the present invention
  • FIG. 2 is an enlarged vertical sectional view taken along the line 2-2 of FIG. I, showing the parts in their normal inoperative position; i
  • FIG. 3 is a view similar to FIG. 2 showing the parts in their impact blow actuated position
  • FIG. 4 is a sectional view taken along the line 4-4 of FIG.
  • a fluid pressure operated fastener driving device which embodies the principles ofthe present invention.
  • the device shown constitutes a conventional fastener driving device produced commercially by Bostitch Division of Textron Inc. under the trade name Mark Il, modified to embody the principles of the present in vention. lt will be understood, however, that while the principles of the present invention may be readily incorporated in this existing fastener driving device, the present invention is equally applicable to other devices of this type as well as devices specifically developed to embody the present inven tion.
  • the specific structure of the conventional elements which form a part of the novel combination of the present invention can be varied, as desired.
  • the device l includes many structural elements which are not modified in accordance with the principles of the present invention, the present description will be primarily concerned with the modifications of the conventional structure which have been effected to incorporate the features of the present invention therein. lt will be understood that a detailed understanding of the structure and mode of operation of the unmodified conventional structure can be had by reference to commonly assigned U.S. Pat. to Smith No. 3,051,135 dated Aug.
  • device l0 includes a main rigid housing structure, generally indicated at 12, which includes a body portion 14, an integral handle portion 16, a fixed nosepiece portion 18 defining a drive track 20, a magazine assembly 22 fixed to the nosepiece portion 18 and cooperating with the drive track to feed the leading fastener of a fastener stick contained therein to the drive track.
  • the body portion 14 of the housing structure 12 includes a main driving cylinder 24 within which a driving piston 26 is mounted for movement between the ends thereof.
  • a main driving cylinder 24 within which a driving piston 26 is mounted for movement between the ends thereof.
  • an inwardly directed flange 28 At the end of the cylinder remote from the nosepiece portion 18 there is provided an inwardly directed flange 28, the lower inner peripheral portion of which defines a valve seat forming a part ofa main control valve means, generally indicated at 30.
  • the main control valve means 30 includes an annular valve member 32 which is mounted for movement between a first position ofengagement with the valve seat of flange 28 which closes off communication between the adjacent end of the cylinder 24 and an air pressure reservoir 34 defined by the interior of the body portion adjacent the cylinder 24 and the interior of the handle portion 16 and a second position spaced from the valve seat defined by the flange 28 permitting communication between the reservoir and the adjacent end ofthe cylinder 24.
  • the reservoir 34 is adapted to be continuously communicated with a source of pressure (not shown) through a line 36 or the like.
  • the main valve member 32 is in the form of an annular ring of resilient material mounted within a peripheral groove formed within the lower end of an elongated hollow member 38 which extends upwardly through the fiange 28 and has a piston portion 40 fixedly secured to the upper end portion thereof.
  • the piston portion 40 is slidably mounted within a pilot pressure control chamber 42, the inner end of which communicates with the reservoir 34, as by a central opening 44.
  • the outer end of the chamber 42 is closed by a closure cap 46 which, in accordance with the principles of the present invention, is modified to include a cylindrical opening 48 concentric with the hollow member 38 and the cylinder 24.
  • the opening 48 is formed with an annular groove to receive annular sealing means, such as an O-ring seal 50 or the like.
  • the piston portion 40 is modified to include integral cylindrical portion 52 extending outwardly through the opening 48 in sliding sealing engagement with the O-ring 50.
  • the outer extremity of the cylindrical portion 52 has its exterior periphery formed to engage within a socket 54 formed in one end ofan impact blow receiving member 56.
  • Piston portion 40 and the adjacent part of the cylindrical portion 52 have a central opening 58 formed therein which communicates with the adjacent end of the hollow member 38. ln the embodiment shown, the piston portion 40 together with the integral outwardly extending cylindrical portion 52 constitute a separate piece from the hollow member 38 but these pieces are fixedly secured together in rigid relation as by a plurality of bolts 60,
  • the opening 58 is communicated with the chamber 42 by any suitable means, such as a plurality ofcircumferentially spaced radially extending ports 62 formed in the part of the cylindrical portion 52 adjacent the piston portion 40.
  • the main control valve member 32 is moved between its first and second positions by introducing air under pressure from the reservoir into the pilot pressure control chamber 42 and exhausting air under pressure from the chamber 42.
  • This action is accomplished by means of a secondary valve means, generally indicated at 64, which is normally biased into a first position closing a port 66 which serves to communicate the reservoir with the chamber 42 through a passage 68.
  • the secondary valve means 64 serves to exhaust the chamber 42 to atmosphere through a port 70 which is positioned between the passage 68 and an exhaust passage 72.
  • the secondary valve means 64 is moved from its normally biased first position into a second position by a pivoted trigger 74 wherein port 66 is opened and port 70 is closed.
  • the secondary valve means 64 is fully disclosed in the aforementioned Smith patent to which reference may be had if neces: ary. Briefly, it will be noted that when the secondary valve means is disposed in its normally biased first position, cham ber 42 is exhausted to atmosphere and the fluid pressure within the reserA voir 34 acts on the piston portion 40 through the opening 44 to bias the piston portion and hence the valve member 32 fixed thereto into engagement with the valve seat defined by the flange 28. lt will be noted that the reservoir pressure acts on a surface area which is equal to the difference between the area of the piston portion 40 less the area of the valve member 32 inwardly of its engagement with the valve seat in a direction to close the valve.
  • a fastener driving element 76 fixed to the piston and extending through the drive track 20 serves to engage the leading fastener positioned within the drive track through the operation ofthe fastener magazine 22, to strip the fastener from the fastener stick, and to drive the fastener outwardly ofthe drive track into a workpiece.
  • the device 10 includes a pneumatic return means, generally indicated at 78, which serves to effect movement of the piston from its fastener driven position through a return stroke into its fastener receiving position in response to the movement of the secondary valve means 64 from its second position into its first position which in turn closes the main valve means 30.
  • a pneumatic return means generally indicated at 78, which serves to effect movement of the piston from its fastener driven position through a return stroke into its fastener receiving position in response to the movement of the secondary valve means 64 from its second position into its first position which in turn closes the main valve means 30.
  • the pneumatic return means 78 includes a tubular member 80 fixed at one end to the piston 26 extending therefrom into the hollow member 38 and having a piston portion 82 formed on the opposite end thereof in sliding sealing engagement with the interior of the hollow member 38.
  • the end of the tubular member 80 adjacent the piston portion 82 is thus communicated with the chamber 42 and its opposite end is communicated with the cylinder 24 by means of a plurality of circumferentially spaced radially extending apertures 84.
  • Mounted interiorly within the hollow member 38 at a position adjacent the valve member 32 is an annular sealing means, such as an O-ring 86, which slidably sealingly engages the exterior periphery of the tubular member 80 in spaced relation to the piston portion 82.
  • the O-ring seal 86 and piston portion 82 define an annular air return chamber 88 which is communicated at all times with the reservoir as by a plurality of circumferentially spaced radially extending apertures 90 formed in the hollow member 38.
  • the modifications of the device to include the impact blow receiving member 56 and the cylindrical portion 52 integral with the piston portion 40 permits the fastener driving element 76 to be moved through a drive stroke and a return stroke in response to the application of an impact blow, as by a mallet, or a hammer or the lkejdesignated by the letter M in FIG. 1.
  • the device 10 modified to embody the principles of the present invention is thus capable of being actuated both in response to an impact blow and conventionally by the actuation ofthe trigger 74 at the option of the operator.
  • the cylindrical portion 52, piston portion 40, and hollow member 38 act as a motion-transmitting mechanism which transmits the impact movement of the impact blow receiving member 56 to the main valve member 32 thus moving the latter from its first position in engagement with the valve seat defined by the flange 28 into its opened position communicating the reservoir pressure with the adjacent end of the cylinder so as to effect the drive stroke of the piston 26.
  • the force of the impact blow is sufficient to overcome the air pressure bias of the main valve member 32 and that this movement of the main valve is instantaneously responsive to the impact blow.
  • the rapid opening movement of the main valve in response to the impact blow causes the drive stroke of the piston to occur almost simultaneously with the opening of the main valve so that the impact blow, which is applied in the same direction as the direction of the drive stroke ofthe fastener driving element 76, aids in the driving of the fastener into the workpiece and further serves to dissipate any recoil action which might occur.
  • the reservoir pressure bias on the main valve will cause the latter to return to its closed first position. Since the secondary valve means 46 is already disposed in its normally biased first position, the return stroke of the piston is immediately effected in the manner previously described.
  • the main valve 32 is moved into its opened position in response to the impact blow in the same direction in which the impact blow receiving member is moved by the application of the impact blow itself. While an arrangement of this type is preferable, it will be understood that where the main valve is moved into opened position in a direction opposed to the direction of movement ofthe impact blow receiving member when the irnpact blow is applied thereto, a reversing motion transmitting mechanism can be utilized.
  • the irnpact blow receiving member be mounted so as to move in the same direction as the direction of movement of the fastener driving element through its drive stroke, an optimum position of the impact blow receiving member being in longitudinal alinement with the fastener driving element 76, although it is within the contemplation of the invention to position the impact blow receiving member at locations other than one of longitudinal alinement with the fastener driving element.
  • the present invention has general utility in the fastener driving art, it is particularly suited to the use of fastener driving devices in installing flooring and the like, as for example, tongue and groove boards B as shown in FIG, i. ln such usage, the impact blow which is applied to actuate the device can also be used to insure a tight tongue and groove engagement of the board B through which the fastener is driven.
  • a board-engaging fixture generally indicated at 94, is preferably attached under the nosepiece portion 18 and the adjacent part of the magazine assembly 22, in accordance with conventional practice.
  • An embodiment of such a fixture is illustrated in FIGS. 1--3 ofthe drawing which includes a bottom wall 96 having a board engaging pad 98 detachably secured to the lower surface thereof. At one end ofthe pad 98. the bottom wall extends downwardly to provide a gauge portion 100, the bottom wall extending horizontally from the lower end of the gauge portion to provide a support portion 102.
  • a pair of generally triangularly shaped sidewalls 104 Extending upwardly from opposite sides of the bottom wall is a pair of generally triangularly shaped sidewalls 104, the upper edges of which are connected by a top wall 106 disposed at an angle of approximately 45with respect to the bottom wall 96.
  • the top wall 106 is provided with an aperture 108 to receive the nosepiece portion 18 and adjacent part of the magazine assembly 22.
  • the fixture 94 is detachably secured to the device 10 by means of bolts 110, which serve to secure the nosepiece portion of the device to the body portion of the housing structurefln the juncture between the guide portion and support portion 102, the bottom wall 96 is provided with an opening 112 in alinement with the opening 108 to receive the nosepiece portion 18 of the device.
  • a transverse wall 114 is provided between the sidewalls 104 in a position to be engaged by the bottom of the adjacent part ofthe magazine assembly 22.

  • the fastener driving element 76 is disposed so as to drive the fastener in a I45"angle through the board in the juncture of the tongue with the top edge of the board.
  • auxiliary handle attachment 116 of conventional construction may be utilized, if desired.
  • auxiliary handle at ⁇ tachment includes a generally L-shaped handle member 118 providing a generally horizontally extending upper handle portion and generally upright leg portion the lower end of which is rigidly secured to an L-shaped bracket 120.
  • the L- shaped Bracket is secured to the exterior of the handle portion 16 ofthe housing structure by a pair of L-shaped bolts 122 having threadly mounted on each end thereof nuts 124,
  • the intensity of the impact blow applied to the impact blow receiving member by the operator is, of course, considerably less than that required to actually drive the fastener into the workpiece.
  • the intensity is more in the nature of that required to insure a firm tongue and groove engagement of the board being nailed. Since in the normal installation of flooring the installer will usually apply blows to the board being nailed, the operation of the present device simplifies installation notwithstanding the fact that more effort is required to actuate the device by an impact blow than is required to digitally actuate the trigger.
  • the device of the present invention provides an overall improvement in the operation because the actuating impact blow is not only utilized to insure a tight tongue and groove engagement of the board being fastened but serves as well to aid in the fastener driving operation and to dissipate any recoil action in the manner previously described.
