Definitions

  • the technology disclosed herein relates generally to automatic screw driving equipment and is particularly directed to an automatic screw driving tool or an attachment of the type which has a narrow front-end profile so that it is capable of driving screws (or other rotatable fasteners) that are in hard-to-reach positions, such as corners or angled members.
  • Embodiments are specifically disclosed as having an extending mechanism within an elongated slide body subassembly, so that the drive elements extend farther away from the main body structure of the tool/attachment, while still providing a stable and rugged overall tool structure to reliably drive screws.
  • One embodiment uses a timing belt structure; another embodiment uses a gear train structure.
  • Another feature of the technology disclosed herein is an external depth of drive adjustment subassembly that is mounted external to the feed tube housing, yet has a simple adjustment that does not lose its setpoint easily. By placing the depth of drive mechanism outside of the interior areas of the feed tube, the slide body subassembly can be shortened while still maintaining an easily adjustable depth of drive capability.
  • a further feature of the technology disclosed herein is the use of a dovetail shape on certain surfaces of the slide body subassembly, which allows the slide body subassembly to be robustly mounted so that it is capable of operating with long fasteners while also having the nosepiece mounted in an extended position for use with those fasteners.

  • FIG. 1 shows a hand-held fastener driving tool combination, generally designated by the reference numeral 5.
  • an attachment assembly 10 (the "attachment,” or sometimes referred to as the “tool” or the “attachment tool")
  • a separate screw gun 6 is available from many different manufacturers, including Senco Products, Inc. and DeWalt.
  • the screw gun 6 has an output bit (not visible in this view) that can drive the head of a screw or other type of rotatable fastener.
  • the attachment 10 mates to the front end of the screw gun 6 by use of a separate adapter 8. Once the attachment 10 has been mounted to the screw gun 6, a collated strip of screws can be used with the screw gun 6, via this attachment 10.
  • Attachment assembly 10 includes a housing portion 20, a front end portion 30, a feed rail portion 40, and a screw feed portion 50.
  • Fastener driving tool 10 is designed for use with a flexible strip of collated screws, and the flexible collated screw strip subassembly is generally designated by the reference numeral 60.
  • the housing portion 20 of the tool includes a front "feed housing” outer shell structure 22, and bottom gripping surface 24.
  • Housing portion 20 is also sometimes referred to herein as an "elongated housing.”
  • Toward the front of housing portion 20 is an elongated “feed tube” 26, which houses certain movable portions of the tool 10, as discussed below.
  • the feed tube 26 is fixedly attached to the housing portion 20, and is also sometimes referred to herein as a "first member.” It will be understood that feed tube 26 can be of any desirable cross-sectional shape while performing its functions (e.g., rectangular, square), and that it is substantially square in cross-section in the illustrated embodiments.
  • the feed tube 26 has a longitudinal axis that runs between a substantially open front end and a substantially open rear end, which are at opposite ends of the feed tube; a drive bit 66 fits through the rear end of the feed tube, and is substantially parallel to the longitudinal axis.
  • the feed tube 26 is mainly hollow, that is, it has an interior volume that is mostly empty space, to allow the slide body subassembly to move in and out of the front end of the feed tube.
  • the collated strip 60 subassembly slides through a feed rail 42 that is mounted onto pedestals 46 and 48 that are mounted to the upper surface of the housing 22.
  • a grip area 24 On the lower surface of the housing 22 is a grip area 24, for placement of the user's hand.
  • Attachment 10 includes an innovative external depth of drive adjustment subassembly 80 (see FIG. 2 ), and typically will have a depth of drive indicator (not shown).
  • the housing 22 thus exhibits a "mating end" near the adapter 8, which receives the front end of the screw gun 6.
  • the front end portion 30 includes a moveable nosepiece 32, which is attached to a slide body subassembly 34. Both the nosepiece 32 and slide body subassembly 34 are moveable in a longitudinal direction of the tool 10, and when the nosepiece 32 is pressed against a solid object, the fastener driving tool 10 will be actuated to physically drive one of the screws into the solid object, also referred to herein as the "workpiece.”
  • Nosepiece 32 has a front surface 36, which preferably has a rough texture such as sandpaper, so that it will not easily slide while pressed against the surface of the workpiece when the tool is to be utilized.
  • the nosepiece 32 is detachable from the slide body subassembly 34 so that the nosepiece can be re-positioned for different lengths of fasteners, and then re-attached.
  • the nosepiece 32 has a plurality of screw length positioning holes 38 (see FIG. 2 ), which are used to attach nosepiece 32 to the slide body subassembly 34 at different relative positions to one another.
  • the nosepiece is thus adjustably affixed (i.e., mounted) to the slide body subassembly.
  • Slide body subassembly 34 is also sometimes referred to herein as a "second member,” or an “elongated slide body.”
  • the nosepiece 32 also has a rear inclined edge 119, which works against another inclined surface 95 that is part of a depth of drive subassembly 80, which is described in greater detail below, in conjunction with the description of FIGS. 33-36 .
  • Nosepiece 32 is elongated, and has two opposite ends: a front end at 36 and a rear end at the inclined edge 119. As the tool is actuated (during a fastener driving event), nosepiece 32 has an axis of movement that is substantially parallel to the longitudinal axis of the feed tube 26.
  • the slide body subassembly 34 is movably "attached" to the feed tube 26, such that slide body subassembly 34 essentially slides along predetermined surfaces proximal to feed tube 26.
  • an angled slot 28 is formed in feed tube 26 to provide a camming action surface (essentially a slotted opening having a curved portion and a straight portion) for a cam roller (or “cam follower”) 70 (see FIG. 2 ) to traverse as the slide body subassembly 34 moves, relative to the feed tube 26.
  • This action is used to cause the "next" fastener of the collated strip (see below) to index to a "firing position" (or “drive position"), by way of an indexing action of the slide body subassembly 34 (which indexing action is internal to the slide body subassembly).
  • the guide rail portion 40 includes a straight guide member 42, and an angled "front portion” guide member 44, that each can receive a flexible collated strip of fasteners, in this case the collated screw subassembly 60.
  • the collated screw subassembly 60 mainly consists of a plastic strip 62 that has several openings to receive individual screws 64.
  • the overall collated screw subassembly is flexible to a certain degree, as can be seen in FIGS. 30 and 31 by the curved orientation of the plastic strip 62 as it is fed through the slide body subassembly 34.
  • the main purpose of tool 10 is to drive rotatable fasteners (e.g., screws or bolts) that are provided in the form of the flexible collated strip subassembly 60.
  • the individual screws 64 are held in place by a flexible plastic strip 62, and as the screws traverse through the guide members 42 and 44, they are ultimately directed toward the front end portion of the tool 30 until each of the screws 64 reaches the "drive" position at 68.
  • the left-most screw 64 has been indexed to the drive position at 68 (see FIG. 31 , for example), and thus is now essentially co-linear with the main drive components of the tool 10.
  • the plastic strip 62 will eventually make contact with a sprocket 130 (see FIG. 2 ) that acts as a rotary indexer, and which is located inside the slide body subassembly 34.
  • the sprocket moves each of the portions of the plastic strip 62 into a proper rotary position so that their attached screws 64 eventually end up in the front-most drive position 68.
  • the sprocket is sometimes referred to herein as the "output member" of the slide body subassembly, which creates an indexing motion.
  • the tool 10 will now be free to allow the sprocket to perform its rotary indexing function and to bring forth the next screw 64 into the front-most drive position at 68.
  • This type of screw-feed actuation can be referred to as “indexed on return,” since the "lead screw” is moved into the "firing position” at 68 as the nosepiece 32 is released (or “returned") from the surface of the workpiece.
  • the tool 10 can also be configured in an alternative screw-feed actuation mode, in which the lead screw is moved into the firing position at 68 as the nosepiece 32 is pressed against the surface of a workpiece; this type of screw-feed actuation can be referred to as "indexed on advance.” If tool 10 is configured for indexed on advance, then the lead screw would not yet be in the position at 68 at the moment the nosepiece 32 is "relaxed” or “free,” in its non-firing state. Instead, the lead screw is not indexed into the firing position at 68 until the nosepiece 32 is "pushed in" (or “advanced") toward the main body portion of the tool 10 (e.g., toward the adaptor 8), which is discussed below in greater detail. Note that the indexed on advance configuration is a preferred mode of operation for tool 10. It will be understood that both the indexed on advance and indexed on return screw-feed actuation modes of operation can work with the technology disclosed herein.
  • FIG. 2 many of the components of the tool 10 are illustrated in an exploded view, which allows most of the internal components of the slide body subassembly 34 to be viewed.
  • a slide body cover 104 is mated to a slide body support 102, and these two rather large structures will contain the mechanical components that make the slide body subassembly operate.
  • Assembled into the slide body cover is a detent pin 108, which travels through a detent housing 106, through a detent spring 110, into an opening of the cover 104.
  • Detent pin 108 mates into an opening of a slide body subassembly plate 120.
  • This nosepiece adjustment subassembly that fits through one of the openings 38 in the nosepiece 32, and also is operatively connected to the slide body cover 104.
  • This nosepiece adjustment subassembly is made up of a plunger 114, a cap 112, and a spring 116.
  • a pair of fasteners 122 and 124 are used to hold the plate 120 in place with respect to the slide body cover 104.
  • FIG. 2 also illustrates an "extending mechanism" that is positioned between the plate 120 and the slide body support 102.
  • This extending mechanism includes a sprocket 130, a drive gear 140, a timing belt 150, and a feed pawl 160.
  • a detent finger 162 There also is a detent finger 162, a torsion spring 164, and a locating pin 166, which operate with the drive feed pawl 160. The operations of these mechanisms will be described in greater detail, below.
  • the sprocket 130 is mounted between locating bushing holes on the slide body support and cover (102 and 104).
  • the drive gear 140 is mounted to a bushing surface (or bearing surface) on the feed pawl 160, and is held in place between that and the slide body support 102, and a pilot hole in the plate 120.
  • the drive feed pawl 160 is allowed to pivot within a slot of the plate 120 and the combination of a cam follower 70 and a cam screw 72, that fit within another slot in slide body support 102, holds the feed pawl in its proper orientation.
  • the plate 120 is held in place with respect to the slide body support 102 by the fasteners 122, 124, and 126.
  • the slide body subassembly 34 is movable within the "feed tube” 26 and "feed housing” 22.
  • Linear guides 170 and 172 are preferably made of a very low friction material, such as TEFLON.
  • the drive bit 66 also fits through a main portion of the feed housing 22, through a spring post 194.
  • the spring post 194 is attached to the feed housing 22 by two fasteners 190 and 192.
  • a large coil spring 67 fits around the circular bearing surface of spring post 194, and presses against a rear surface of the slide body subassembly 34, thereby biasing the slide body subassembly toward the front of the tool (i.e., toward the nosepiece portion of the tool).
  • FIG. 2 also shows more details about the feed guide rail portion 40.
  • the linear guide rail 42 is attached to brackets 46 and 48. Those brackets are positioned on a mounting rail 180, and that rail is affixed to the top portion of the feed housing 22 by fasteners 182, 184, and 186.
  • the larger diameter portion of drive gear 140 includes a relatively circular profile, with multiple extensions at 142 and multiple depressions 144 that are spaced-apart therebetween.
  • the depressions 144 are sized and shaped to receive "bumps" 152 on the timing belt 150, and thus this drive gear also acts as a timing gear.
  • the smaller diameter portion of drive gear 140 is also mainly circular in profile, but with multiple extensions 146. Each of these extensions has an uppermost edge 148, which is used for a function that will be explained below in greater detail.
  • the feed pawl has an attached detent finger that mates with these extensions 146 and 148, and acts as a ratchet.
  • the larger diameter portion of sprocket 130 includes several protrusions 136 that extend outward from an otherwise relatively circular diameter outer profile. These extensions 136 engage the openings in collated strip of fasteners, and acts as a primary mechanism for driving the strip of fasteners through the front end of the tool.
  • the smaller diameter portion of this side of the sprocket has a relatively circular profile with multiple extensions at 132 and multiple depressions at 134, which are spaced-apart there between.
  • the depressions 134 are sized and shaped to engage the bumps in the timing belt 150.
  • the sprocket 130 is illustrated, showing its feed pawl side.
  • the sprocket teeth 136 are again depicted, and the other major feature on the site of the sprocket are a series of spaced-apart depressions 138. These depressions are sized and shaped to engage the distal end of the detent pin 108. This action tends to hold the sprocket and collated strip grouping in their proper locations as the drive bit 66 pushes (drives) the fastener (typically a screw) from the collated strip as that fastener is driven into a workpiece.
  • the detent finger 162 is illustrated.
  • This pin has a circular portion with a circular opening that can rotate about the locating pin 166.
  • Detent pin 162 also has an extension with a distal end 163. This distal end provides a contact surface and mechanically interfaces with an opening of the feed pawl 160.
  • Detent pin 162 also contains a mechanical stop at 161 which holds the torsion spring 164 in place.
  • Feed pawl 160 has a large circular area with a large arcuate depression at 159. It also has an extension arm 157 that has a cylindrical opening at its distal end, and that opening allows it to pivot about the cam screw 72. There is a "feed post" 158 near the distal end of the extension arm 157. The other end of the torsion spring 164 will rest against that post (see FIG. 20 ).
  • the slide body support 102 is illustrated.
  • the slide body cover 104 is illustrated, which includes various openings for elements such as fasteners and the detent spring 110.
  • the nosepiece adjustment subassembly which includes the plunger 115, cap 112, and spring 116. This nosepiece adjustment subassembly is used for different screw lengths, which can be accommodated by a single tool 10.
  • the belt drive subassembly is illustrated, showing the main components of the drive gear 140, sprocket 130, and timing belt 150.
  • the feed pawl 160 is also illustrated, along with its associated detent finger 162.
  • the cam follower 70 is illustrated on FIG. 18 , as fitting into an opening at the distal end of the extension of the feed pawl 160.
  • the timing belt 150 has multiple raised “bumps” (or protrusions) 152, and that these bumps fit into the depressions 144 of the drive gear 140, and also into the depressions 134 of sprocket 130. However, only a few of these multiple “bumps” 152 are illustrated on FIGS. 18 and 19 , for the sake of clarity. But it will be understood that the raised, spaced-apart bumps 152 are actually in place along the entire inner surface of the timing belt 150. The other views of the technology disclosed herein that show the timing belt 150 do not show any of these bumps 152 except at the locations where they actually engage depressions of the sprocket and the timing gear, again for the sake of clarity.
  • the belt drive subassembly is again illustrated, this time as it would be assembled into the slide body support 102.
  • the sprocket 130 and the timing gear 140 are illustrated as engaging bumps of the timing belt 150.
  • the interior edge 148 of the drive gear 140 can be seen as engaging the detent finger 162 at its distal end, while the extension 157 of the of the feed pawl can be seen as having its associated cam follower resting inside the curved slot 101.
  • the torsion spring 164 is illustrated, and its two extending arms can be seen on FIG. 20 .
  • the torsion spring is centered about a locating pin 166, which holds the detent finger 162 in place in an opening of the feed pawl 160.
  • cornerfit clearance is defined as the distance from the front of the nosepiece to the front of the outermost housing portion when the tool is completely compressed (i.e., the slide body has been completely pushed into the feed tube). This distance (the cornerfit clearance) is needed for driving a framing square into standard commercial channels while clearing the edges, or for driving a screw into the corrugated roof decking.
  • the overall design of the illustrated tool allows for an "advance on return” mode of operation, in which the screw or fastener is indexed to the drive position during the return portion of the operating cycle, instead of during the advance portion of that cycle.
  • this return mode or “advance on return” mode
  • the fastener moves into place (at the drive position).
  • the push stroke will reset the mechanism for the next feed stroke.
  • the attachment tool 10 is illustrated in a perspective view that is mainly from the front, which is the end of the tool that makes contact with the workpiece.
  • the "lead fastener" 68 is visible, as if it were about to be emplaced into the workpiece.
  • the orientation of the nosepiece 32 with respect to the right side of the housing 22 can be seen, and this also illustrates the linear guides 170 and 172, which will be discussed below in greater detail.
  • FIG. 22 a top plan view of the attachment tool 10 is illustrated, in which the tool is in its non-actuated condition.
  • the "lead” fastener 68 is illustrated, along with some of the other fasteners 64 that are still connected to the collated strip. (In reality, the "lead” fastener 68 will no longer be attached to the collated strip if this tool was an "index on advance” tool.)
  • FIG. 22 shows a section line 23-23
  • FIG. 23 is a cross-section view of the tool 10 taken along the section line.
  • the feed tube 26 outer framework can be seen, as a largely square-shaped structure.
  • the slidable workings of the slide body subassembly 34 In the middle of the slide body subassembly is the drive bit at 66.
  • the collated screw strip 62 Above the slide body subassembly is the collated screw strip 62, with a portion of one of the fasteners 64 still attached. These would be arriving at the drive position by sliding along the guide rails 42 and 44.
  • the feed tube 26 is easily seen, as having a square profile and shape. Within that feed tube are the linear guides 171 and 172. These guides make contact with the nosepiece 32 and angled portions of the nosepiece designated at the reference numerals 174 and 176. This is referred to herein as a "dove-tail" shape, and provides fairly rigid support for the nosepiece 32 as it slides forward and backwards along the bearing surfaces of the linear guides 170 and 172. It can be seen that the angled nosepiece portions 174 and 176 slide along similarly angled surfaces of the linear guides 170 and 172.
  • FIG. 24 the front portion of the attachment tool 10 is illustrated in a top plan view, and this time it has been actuated so that the slide body subassembly 34 has been pushed into the feed housing 22.
  • the "lead fastener” 68 has been torn away from the collated strip 62, and the screws (or fasteners) 64 that are visible on FIG. 24 have not yet reached the drive position, and they are still attached to the screw strip 62.
  • FIG. 25 is a cross-section view taken along that line.
  • the attachment 10 is illustrated, and shows the components of slide body subassembly 34 essentially surrounded by the feed tube 26.
  • the nosepiece 32 Just to the outside of the feed tube, along the "right-hand side" of the tool, is the nosepiece 32 (to the left in this view).
  • the linear guides 170 and 172 act essentially as linear bearings for the movement of the nosepiece 32 proximal to and just inside the right-hand interior surface of the feed tube 26. As noted above, this provides a firm structure for the combination of the nosepiece 32 and the slide body subassembly 34, as they move inside the feed tube 26.

  • the nosepiece 32 is tracked (guided) within the feed tube 26, primarily on one side.
  • Most conventional automatic feed screw systems use the slide body subassembly as the sole means of support within the feed housing. Sizing of the inside housing dimensions becomes critical with those previous designs.
  • the dovetailed slide body cover at 179 allows the nosepiece 32 to slide and track smoothly along the slide body cover when making screw length adjustments, by adjusting the nosepiece position holes 38.
  • this dovetailed feature is also the primary support for the slide body subassembly 34.
  • portions (at 179) that have outer corners that are broader (i.e., spaced-apart at a greater distance) than their more interior outer surfaces.
  • the combination of the slide body cover at 179 and the nosepiece portions 174 and 176 create a single body structure during normal operation of the tool 10, for driving a fastener into a workpiece; the nosepiece portions 174 and 176 are sometimes referred to herein as a "dovetail shaped body member.”
  • the upper and lower linear guides (or bearings) 170 and 172 are made of a material having a low coefficient of friction, such as TEFLON. They support the nosepiece, inside the feed housing 22. The tapers on these linear guides “lock in” the nosepiece 32, and bias it to one side. As can be seen on FIG. 25 , the angled shape (the taper) of linear guides 170 and 172 correspond to the angled shape of the dovetail outer surface of the nosepiece 32, specifically at their outer sliding surfaces at the portions 174 and 176. In this manner the dovetailed surfaces of the slide body subassembly provide a stronger, more durable surface along the guide rails and support the extending mechanism within the slide body subassembly, thereby having an improved linear tracking capability.

  • This is a representation of an existing prior art sold by Senco Brands, Inc., which is the model number DS200-AC.
  • This is an integral tool, which includes all of the motorized and trigger components, as well as the final drive components, including the collated strip indexing components.

  • a drive bit 266 that extends from the motorized gearbox portion of the tool toward the front end of the tool, so that it will engage with one of the screws 264 when the tool is actuated.
  • the dimension “H1” represents the height of the outer dimension of the feed tube 222.
  • the dimension “W1” represents the width of the outer portion of the feed tube 222.
  • a dimension “P1” represents the distance from the further-most end (the “distal” end) of the drive bit 266 to the further-most end (or “distal” end) of the feed tube 222. This P1 dimension is also referred to as the "lick-out" characteristic of the tool.
  • the lick-out characteristic of a power tool is important, and in general, it is better to have a longer lick-out dimension than a shorter one. This is because a longer lick-out dimension will allow a tool to reach into smaller, tighter places to drive a fastener than a tool that has a shorter lick-out dimension. Since the automated screwdriver tools using collated strips of fasteners tend to be designed with a front-end portion that "collapses" into a feed tube, it usually is the outer dimensions of the feed tube that becomes the controlling factor as to whether a given tool can reach into a small working area, or not. Therefore, the longer the lick-out dimension compared to the overall size of the feed tube, the more "small” areas the tool can be used with. This can be expressed as a ratio: either P/H (the lick-out divided by the feed tube height) or P/W (the lick-out divided by the feed tube width) for a square or rectangular feed tube.
  • FIG. 27A illustrates a top, plan view in cross-section of the same prior art tool, model DS200-AC, after the tool has been "collapsed” because its nosepiece has been pushed against the surface of a workpiece, which means the tool was used to drive a fastener into that workpiece.
  • FIG. 27B is a right side elevational view of the same tool, under the same conditions.
  • the slide body subassembly 234 has been pushed quite far into the feed tube 222, and the nosepiece 232 has been pushed back almost all the way to the outer edge of the feed tube 222.
  • This "outer edge" of the feed tube 222 is also referred to herein as its "distal end.”
  • the drive bit 266 is the component of the tool that is furthermost to the front end of the tool.
  • the lick-out dimension P1 is easily seen as the distance between the distal end of the drive bit 266 and the distal end of the feed tube 222. This dimension does not change for a particular tool as the tool is operated. It merely looks different, because the slide body and nosepiece have been pushed into the inner open spaces of the feed tube 222.
  • FIG. 28 a left-side elevational view of the technology disclosed herein is illustrated, showing the front end portions in greater detail.
  • This includes the nosepiece 32, the movable slide body subassembly 34, and the feed tube 26, with its camming surface or slot 28. Also visible are the guide rail 42 and its forward extension 44, and the collated strip of screws 60, in which the strip itself is at 62, and the screws at 64. Finally, the depth of drive subassembly 80 is visible, having an inclined surface 95. This tool is shown in the unactuated position, in which the nosepiece and the slide body subassembly are fully extended, away from the feed tube 26.
  • FIG. 29 the same tool is seen in the same type of view, except now the tool has been collapsed by which the nosepiece has been pushed in (to the right) due to an operation for driving a fastener.
  • the movable nosepiece 32 and movable slide body subassembly have been pushed into the feed tube 26 as far as is possible, and therefore, most of the slide body subassembly is not visible, except for the fact that this view is in partial cut-away.

  • a portion of the sprocket 130 has been cut away, so that the distal end of the drive bit can be seen.

  • the height dimension "H2" which is the height of the outer surfaces of the feed tube 26. The width dimension of this feed tube was illustrated on FIG. 23 , by the dimension "W2".
  • FIG. 31 shows the same structure, but in the condition in which both the nosepiece 32 and the slide body subassembly 34 have been partially pushed into the feed tube 26.
  • the distance the nosepiece has been pushed into the feed tube is sufficient to move the outer or distal end of the drive bit 66 much closer to the head of the lead screw 68, as seen in the cut-away area in the sprocket region.
  • the camming roller 70 has been displaced by an amount sufficient to index the sprocket 130, so that the "next" fastener 64 will be indexed to that drive location 68.
  • the lick-out dimension P2 is again visible on FIG. 31 , and extends from the distal end of the feed tube 26 to the distal end of the drive bit 66.
  • exemplary dimensions that are illustrated on FIGS. 30 and 31 (and also FIG. 23 ) are as follows:
  • the ratio of the lick-out dimension compared to the height (or width) dimension is as follows:
  • this ratio value (1.204) is much higher than the ratio of the prior art tool discussed above, which was the ratio P1/H1 (and P1/W1). This allows the tool 10 to fit into smaller areas for driving rotatable fasteners, such as screws or bolts.
  • the feed tube that is illustrated and described herein need not be square; rectangular feed tubes are also common in these types of tools.
  • the internal workings of the slide body subassembly must still fit within such feed tubes, no matter their exact shape or size, and a robust slide body subassembly will always require some minimum front profile, having a maximum height or width dimension, which would also be true for a circular or elliptical feed tube.
  • any feed tube shape there will always be a discernable width or height dimension (or a diameter dimension) that becomes the limiting factor in allowing the fastener driving tool to fit within a given small area and have the capability of driving a rotatable fastener.

  • the feed pawl 360 has a large opening that is actuated by the detent finger 326, so that this subassembly acts as a ratchet. It will be seen that, as the feed pawl 360 rotates, so do the gears 340, 342, and 344, which then causes the sprocket 330 to rotate, and thereby to index the collated strip of screws. This can be built as a sturdy "extending mechanism", and the multiple drive gears can be made as large as necessary, so long as they fit within the confines of the interior spaces of the slide body subassembly 334.

  • the user In order to make adjustments to the depth of drive unit 80, the user should depress and hold down the latch pin tab 93. While holding the latch pin down, the user should rotate the adjustment screw 84. A clockwise rotation is for a higher (or “up”) setting, which will cause the fastener to penetrate shallower, and a counterclockwise is for a lower (or “down”) setting, which will cause the fastener to penetrate deeper. Rotating the adjustment screw 84 causes the adjustable stop block 83 to travel up or down. This up and down travel is in a direction that is transverse to the longitudinal axis of the feed tube, which is substantially perpendicular to that longitudinal axis.
  • FIG. 36 there is an area at 90 of threaded engagement between the adjustable stop block 83 and the larger thumb wheel/screw 84.
  • thumbwheel 84 When the thumbwheel 84 is turned, its threaded engagement with the stop block 83 will cause that stop block to be displaced, either up or down.

  • a "fastener driving event” or “fastener driving cycle”
  • the nosepiece 32 is pushed rearward, which is to the right in FIG. 37 , and the rear edge 119 of nosepiece 32 will eventually come into contact with the inclined surface 95 of the stop block 83.
  • the clutch of the motorized driving tool (not shown) will be disengaged, and the drive bit 66 (not shown in this view) will stop turning. Therefore, the position of the stop block 83 becomes the controlling factor as to when the tool stops trying to drive a rotatable fastener (such as a screw), and in effect, acts as a mechanical "depth of drive” controller.
  • FIGS. 28 and 29 The above action is illustrated on FIGS. 28 and 29 .
  • the nosepiece 32 is extended, as it has not been actuated. Its rear angled edge 119 is seen to the left (on this view) of the inclined surface 95 of the stop block 83.
  • FIG. 29 the nosepiece 32 has been actuated all the way to its right-most movement (on this view), and its rear angled edge 119 has made contact with the inclined surface 95 of the stop block 83. Note that in these two views, the stop block 83 has been placed near its bottom-most travel position.
  • the midpoint position of the stop block 83 that is illustrated on FIG. 37 will cause the rotatable fastener to be driven to a "midpoint depth" of the tool's overall capability.
  • the following example discusses what occurs when the stop block is moved to other positions, from this midpoint location. If the moveable stop block 83 is adjusted all the way to its top-most position, then rear edge 119 will come into contact with inclined surface 95 sooner during the rearward travel of the nosepiece 32 (because the angled edge 119 extends farther to the rear (to the right on FIG. 37 ) at a higher position along the vertical surface of the nosepiece 32, and the clutch of the motorized tool will be disengaged sooner in its drive cycle. Therefore, the drive bit 66 will not be as far forward when its rotation stops, and thus the rotatable fastener will not be driven as far into the workpiece.
  • the depth of drive adjustable thumb screw typically is located directly inline with the back of the nosepiece, i.e., within the feed housing. Therefore, the overall length of the nosepiece must be shortened to accommodate the added mechanisms. And when using the longest screw length, with the nosepiece set at the longest length, if the feed system is in its home (unactuated) position (i.e., when the nosepiece is fully extended), then more than half (almost three-quarters) of the bearing support between the housing and the back end portion of nosepiece is lost. In addition, virtually all the depth of drive range is lost. The lack of support bearing surface sometimes will cause alignment and stability problems; this is due to premature wear of the linear slide bearings.
  • the current embodiment takes advantage of this fact by mounting the depth of drive adjusting mechanism assembly on the outside of the housing, thereby maximizing the available bearing ratio in front and rear.
  • the depth of drive subassembly 80 is mounted external to the feed tube housing 22 which allows for an improved bearing ratio between the nosepiece 32 and the feed tube housing. This also allows for a greater insertion distance of the nosepiece into the feed tube housing 22.
  • portions of the slide body and nosepiece subassemblies are able to travel back past the depth of drive components, thus mitigating a length increase on the overall feed system, while providing more bearing surface between the nosepiece and frame while at the extended (at rest) position.
