The invention relates to stapling devices in which it is formed like and used simi-'lar will'of the o erator.
I accompllish the above said ob]ects by` to an Ordinary hand-hammer, and wherein staples maybe fed under and driven by the hammer-head as each blow is struck or at the will of the Operator; `and the obJectsi of the improvement are; first, to provide a staple driving" tool of ,rapid operation, convenient to handle and facilitate the driving of staples; secondQto facilitate feeding Ofstaples under the hammer-head as feach blow is struck or at the will of the operator; third, to provide means for charging a number of staples in the form-of a strip or cartridge within the device, and means for feeding continuously into position successive staples for being driven at the making use of the novel form of construction of astaple driving hammer as shown in the laccom anying drawings, 1n, which AFigure is avelitical'side view of the. exterior of the device showino' the method` of securing the handle portiors to the hammer housing together vwith the thumb trigger shown in norositionFi ure 2, a vertical sectional iriivptaken oh thge center line andshowing the working parts in normal position; Figure 3, a vertical cross section thru. the hammer housing and guide'sleeve showing-one of the locking lugs engaging'the hammer housi ing to prevent turning Figure 4;, a sectiona plan Viewl sliow-ing a staple in position been the driver Guides ready to be cut OE driven togethir with the next succeed- 0' sta le in osition for folding, and taken bIfiblinep4-4 (if Fig. ;;Figure 5, a' plan sectional view'taken on line 5--5l of Fig. 2 looking down upon a part ofthe feeding mechanism; Figure 6,'- a cross sectional view taken on line 6-6 of, Fig. 2 showing the construction of the staple holding channel together h an end View yOf the thumb Atriggerl and iftspring for returning it tonormal position Operation; Figure 7, a plan view taken on line 7--7 of Fig. 2 showing the retaining spring for holding staple in verti-l cal position while being driven; FigureS, a fragmented-view taken on line 8-=8 of Fig. 2 showing the driver together with the folding 1927.

furcations in raised position ready for cutting off, drivingand folding the next suc- A prong as at 14 which is formed in and a part of the housing 11, and at 15 is shown the thumb trigger in raised position. In Fig. 2 the hammer 16 is shown with its driver 17 and its folding furcations 18-18 and its return spring 19. At 20 is shown an internal sleeve for the purpose' of supporting the spring 19 and'also for providing a guide to prevent the hammer and driver from shifting out of proper alignment by making use of theslots 20 into which are engaged the i side wings 17 that operate with the hammer 16, and in turn the sleeve 20 engages the housing 11 preventing its shifting by making use of the two lugs 20, one of which is shown in Fig. 3 butting against the end Wall of slot at the bottom of the housing as at 11 this sl'ot being machined aci-oss the bottom of the housing 11 for the purpose of receiving fthe feeding end of the staple channel as shown in Fig. 4 at 21, the top web 22 extending in to the center line as at22 for the purpose of. forming a` hold-down for making use of the last staple at the end of a strip, while the flaps 22 are stopped short-to bear down upon the retaining spring y23 as shown at 24 in Fig. 2, and Fig. 7 while the bottom ianges of the handle memberslO and 10 rest upon the lip 25 and butt against the end of spring 23 for holding it in place. In the llower end of housing 11 -are the openings 26427-28 for the purpose of providing a guide foreach leg of the staple while being driven by the d ri'ver passing down thru the opening 26 while the folding fu'rcations '1S-18 close down over the anvil 29 bending downward the legs of. the next succeeding staple as shown in Fig. l8 at 30 and 31 and entering the openings 27 and 28. The housing 11 beingmade of a suit- 'LUG able material for hardening the top edge of 'the anvil 29 is hardened and sharpened for the purpose of providin a' shearing edge as at 29 for shearing o the staples as the vdriver 17, which is made. also of hardened material and has a cutting edge, passes down thru the opening 26 functioning as a shear and driver. y f
The hammer 16 is'maintained up in normal position as shown in Fig. 2, byl means of the spring 19 acting against the shoulder 32 which in turn butts against the screw cap 33. To prevent the hammer head 16 from moving downward againstthe action` of the sprin 19, as the tool is being raised for striking a low, the pawl 34 engages the abutting face 35 formed in the side 0fthe hammer 16 as a catch.' This awl 34 is connected by its lower arm to the eeding rod 36 that is operated by the thumb trigger 15 which is actuated by being pressed downward after the hammer has been raised into position for striking a blow releasing the hammer head 16 and allowing the feedin pawl 38 to be forced inward, by action 0% the spring 37 feeding the folded staple under the. driver 1 17. As a blow is struck for driving a staple,
the heel of the hammer housing 11 is stoppede by coming in contact with the material to be fastened, as shown at 39 Fig. 8, and due to the kinetic energy of the hammer-head it will continue downward forcing the driverA to shear olf the prepared staple and drive it thru the material 39 and into the fasteni g material 40 overcoming the force of e spring 19, also pressing down and forming t e next succeeding staple as .at30-31 of Fig. 9 by the action of the folding furcations 18A-18 bending the prongs or legs down over the anvil 29. After the staple has been driven the spring 19 will force the hammer head 16 up and/'back against the cap 33; the catch 35 will be in alignment to permit the pawl 34 to drop back intoplace, being actuated by the force of s'prin 41 thru the rod 36 As the pawl 34 rocks ack into-normal position the abuttin face 42 formed as a part of 34 will sta les for feeding. 'flic principal abut wi the face 43 a part of the arm 44 forcing the arm 44 to swing back retracting the lfeeding pawl-38 for engaging the next sucstaple; it being apparent of course 37 must have suilicient 5pt-m' ngth only to rag the strip of staples thru the` channel 22 and that the s ring 41 mounted upon the pin 45 together wit trigger 15 must have suicient strength to actuate Athe mempon the pin 13` and 4still over- 'come the strength of spring 37 to retract the 4pawl 38 to engage another staple thru the opening 46 provi ed inthe web of the channelA 22 for allowing pawl 38 to engage the use for which this t pe of hammer is applicable will he 'for sta ucging onshipping tags, card board postersn 'sition for drivin and for other use where light tacking is required so as not to damage the material being tacked on, and for this'reason the spring 19 should have just suiiicient strength to raise the hammer head 16 back up and against the stop: cap 33 so that as light a blow possible with sufficient force to shearof and drive the staple will be required.
