- the invi -tion herein illust chosen to 001 attract the selectin the form of a her extended ely of the 'i'lir'ection of movement of a the channels 4:0 and parallel to -r 50and provided with un ually pro'ecting selecting portions 62 and respectively with selecting locaions5-l and 56 and to move the carrier 50 o to carry the notch 52 from a receiving the eliecte'd but in the location in aligmnent with the channel l0 of the raceway to selecting locations 54 and 56 to present the tack suspended by its head from the notch in operative relation to the selecting means.
- the selecting bar is o erated in a fixed path transversely of the direction of movement of the tack carrier by rotation of the shaft 51 by which it is carried.
- the path of movement of the selecting means manifestly is nearer the tack carrier 50 in the direct-ion of the lengths of the tacks dependent from the tack carrier at the selecting location 56 which is aligned with the longer projection 64 of the bar 60 than at the ecting location 54 which is aligned with the shorter projection 62 of the bar 60.
- the tack carrier 50 When, therefore, the tack carrier 50 'is moved so as to carry the notch 52 from selecting location 54 to the selecting location 56, the notch 52 which positions the tack relatively to the selecting bar 60 is caused to approach the path of movement of the selecting bar in the direction of the length of the tack.
- the projection 62 of the selecting bar is spaced from the upper surface of the tack carrier 50 at the selecting location 54 by a distance less than the length of the longer tacks but greater than the length ofthe shorter tacks, the operation of the tack carrier 50 and the bar 60 being so timed that the bar is moved by the carrier in the direction indicated by the arrow (Fig. 3), that is, from the open.
- the tack is a short one it will not be engaged the projection 62 of the bar but will be conveyed b the carrier to the selecting location 56 whi e the shaft 51 is completing arevolution into position to be engaged by the projection 64: of the ,bar 60 when it is again moved past the tack carrier 50, the projection 64 of the bar being 5 aced from the carrier50 by a distance less tlian the length of the shortest tacks being operated .upon and operating to remove from the tackcarrier any tacks which are not discharged therefrom at the selecting location 54.
- The. bar 60 is formed with an extreme depression 63 in the vertical plane of the channel 40 whichinsures that the tacks in the raceway. will'not be struck by the selecting bar in its movement.
- Both the tack carrier 50 and the tack selecting bar 60 are preferably and as herein illustrated extended transversely of the channels 40 fromend to end ofthe machine and. both of such members are operatively related to all of the channels.
- Each of said members may be said to comprise a plurality of like colligate sections one of which is associated with each of the assorting stations 2.
- the bar 60 is thus formed with alternating longer and shorter projections 62 and 64.
- the tack carrier is slidably mounted on a brace 65 projecting laterally from the machine frame, and the notches 52 are formed in an angular portion 66 of the carrier extending upwardly in the plane of the raceways.
- a plate 67 pivoted to the frame of the machine at 68 overlies the channels 40 at their delivery ends and serves to prevent any of the tacks from being thrown upwardly from the channels 40 or the notches 52 either by engagement of the selecting bar 60 therewith or otherwise.
- the long tacks removed from the tack carrier 50 at the selecting locations 54 are collected in a common receptacle which should manifestly be separate from that in which are collected the shorter tacks removed from the carrier at selecting locations 56.
- the tacks as they are discharged from the presenting means are caused to fall into hoppers 70 which'are alternately formed with floors 72 arranged to direct the tacks into a receptacle Tel and with floors 76 constructed to direct the tacks into a receptacle 78 constructed as a part of or located adjacent to the receptacle 74.
- the operating means for the machine is as follows. Carried by the shaft 51 on the right hand side of the machine (Fig. 1) are tightand loose pulleys designated together by the reference numeral 82, and endless bolts 84: and 86 are provided for transmit ting the movement of the shaft 51 to the rotary drum 22' and the magazine l respectively.
- the shafts 44: on which the pickers are mounted are operated by endless belts 97 passing over pulleys carried by the shafts 441- and the stud shaft-s .92 and 95, respectively.
- a yielding connection 1s provided between the stud shaft 92 andthe tack carrier '50, said connection comprising a spring pressed plunger 98 mounted in the cam disk 94: and
- the bar 60 may be formed with a number of selecting, portions variously spaced from the tack carrier 50 corresponding to the number of classifications of the tacks which it is desired to make. Thus, if it were desired to assort tacks in more than two groups, the selecting portions or projections 62 and Set of the bar 50 would be replaced by a greater number of selecting portions and the tack carrier would he moved to carry its notch 52 from the receivinn location to all the selecting locations.

MACHINE FOR RECLAIMING FASTENINGS.
Specification of Letters Patent. Patented- Jan, 17, 1922,
Application filed August is, 1919. Serial No. 250,153.
To all whom it may concern Be it known that 1, Roman H. Lawson, a citizen. of the United States, residing at Beverlv, in the county of Essex and State of Massachusetts, have invented certain In provements in Machines for Reclaiming Fastenings, of which the following description, in connection with the accompanying drawings. is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to machines for reclaiming fastenings such, for example, as the metallic fastenings used in the making of shoes. and it has particularly in view the restoration to a condition suitable for use of the tacks which are spilled on the floor in the operation'of lasting shoes and are taken up from the floor together with dirt, trash and the like in the sweepings from the lasting room.
In the lasting of'McKay shoes tacks of two different lengths are used, relatively short tacks being inserted at the shank of the shoe and longer tacks being inserted at the heel seat and toe portions of the shoe where the stock through which the lasting tacks are driven is of greater thick ness than at the shank of the shoe. The operator, commonly, for example, when no lasts first one side of the shoe and then the other at the shank and then, after makinsz he change from shorter to longer fastening-s, lasts the toe in d heel seat, vitln draws the shoe from the lasting machine several times during the lasting operation in order that he may so manipulate the shoe as toprescnt a diiferent point on the shoe in position to receive the tacks insertedby the machine. It is not found practicable to stop the operation of the lasting machine while such changes in the presentation of the shoe to the machine are being inade'and the continued operation of the machine results in a large number of tacks being discharged on the floor about the machine. It is also common for operators to permit the lasting machines to continue in operation while achange is being made from one shoe to another which, of course, adds to the accumulation of the tacks about the machines. In the manufacture of Goodyear weltshoes also, tacks of different lengths are used for lasting the heel seat and the forepart and these tacks tend to collect on the floor of the lasting room. Very large quantities of tacks have heretofore been lost in shoe factories in this and other ways since it has been cheaper to purchase new tacks thanto employ operatives to pick out the spilled tacks from the trash'and' dirt with which they become commingled on the floor and to assort them as to length which is necessary to the end that tacks of a certain them in accordance with a physical characteristic of the fastenings- With a View to putting into eifect the above-mentioned object of the invention the present exemplification of the invention is organized to assort tacks in accordance with their lengths so that tacks of one length may be obtained separate from tacks of a different length.
Asecond feature of the invention resides in the provision of a machine having a plurality of. stations. at which are provided means for operating on tacks, such,.for example, as mechanism for assorting the tacks in accordance with a physical characteristic of the tacks, and means for distributingthe tacks substantially uniformly to. saidstations.
In the illustrated. construction, the means for distributing the tacks uniformly to the various stations comprises a. rotary drum having a series of openings arranged spirally of the circumference of the drum through l ich the tackspass successively to the varioi; stations. 7 l
In accordanceavith another feature of the invention, means operated in a predetermined path of movement is provided for selecting the tacks inaccordancewith their lengths, and the tacks are positioned relatively to the path of movement of the selecting means, by means movable relatively to the ath of movement of the selectin means In the direction of the lengths 0 comprises: members each of which extends in co-operative relation with the assorting stations. i i
. teach, the invention will be herein set fort applican s to operating on last ingtac s, it will be understood that the invehtionj as a whole and certain features thereof areeapahleof use in other applicatibnssiich, forjexampla'as the reclaiming of: other kinds of metallic fastenins, and itjil SitlS O recognized that the mec anical structure here n illustrated and described is ts extensively modified without dep rting' from the principles of the invennon. f
Other objects and features of. the invention will appear as the description proceeds.
In the drawings, 1
Figure 1 is a view in side elevation of a machine according to the invention with parts. broken away to show portions of the interior of the machine; a
\ Fi 2 is a plan view with parts broken awa better to exhibit the assorting mechanisni ofthe machine;
3 is i1 View in front elevation showing the's ide, the picker, and the assorting mechanism at the right hand side of the machine nrrross section; and r Fig. A: is a cross section of the yielding connection'for operating the tack carrier.
Theniachine may be said to comprise generally 1 a plurality of assorting stations 2 having means associated therewith for as sorting the tacks in accordance with their lengths and means for separating foreign material such as dirt, trash and the like from thetacks and distributing them to the assorting stations.
The devices for separating the tacks from foreign material anddistributing them to as assorting stations comprise a rotary cylindrical magazine 4having a screened or otherwise reticulated periphery of a mesh small enough to retainthe tacks in the magazine but through which fine dust may ass into a receptacle 6 supported on a she f 8 formed as a part of a bracket 10 extending fr'omihe machine frame and providing a bearing 19 in which a hollow boss 14 projecting centrally from one side of the magazihei'is journaled. Ablower (not shown) is connected to the boss 14 for producing a flow of air-through the interior of the magaziiie lin order to remove from the magazineanylight trash which may be intermingled with the tacks. The magazine 4 is formed with flanges or fins 16 extending radially inwards from its periphery and operating upon rotation being imparted to the magazine to elevate the contents of the magazine and deliver them upon a chute 18. The tacks are introduced into'the magazine t through a hopper 20 which together with.
the magazine l. constitutes a source of tack supply for the machine as a whole.
The tacks which, having the fine dust separated therefrom by the screened periphery of the magazine -11: and the light trash removed by pneumatic means through the hollow boss 14, may still have coininingled therewith relatively large and heavy pieces of foreign material, are delivered irom'the chute 18 into the end of a rotary drum 22 more of the openings 24% is passing through the lower part of the path of movement of the drum beneath the line oftacks in their advance from the inlet or. receiving end of the drum toward its outlet or dehvery end.
hen, in the continued rotation of the drum. the openings 24 adjacent to thereceiving end of the drum have passed from beneath theline of tacks in the drum, a solid or imperforate part of the drum is presented to the tacks near its inlet end in consequence of which they are prevented from passing from the drum until inrtheir advance movement toward the outlet end of the drum they arrive in alignment with other openings 24 which, by reason of the spiral arrangement of the openings in the drum, pass through the lower portion ofthe path of movement of the drum beneath the line. of tacks in the drum at a later period of its rotation than did the openings nearer the receiving end of the drum. The size and arrangement of the openings 24:, the speed of rotation of the drum, and the delivery of tacks to the chute'lS by the flanges 1.6 of the magazine 4 may be so regulated as .to cause a substantially equal number of tacks to be delivered from the openings 24 of the drum at all points of the drum from its receiving to its delivery end. As shown, the drum 22 is provided with a single row only of openings 24larranged at a relatively high pitch about the periphery of the drum, each of the openings preferably having substantially one half or more of its extent dis posed on thefside'of a'plane at right angles to th axis of the drum 22 and passing through the adjacent end of a contiguous opening opposite from said contiguous opening. Referring to Fig. 1, the line A indicates a plane transverse to the axis of the drum 22 and passing through the end of the opening 126 adjacent to the opening 127, and the line it represents a similar plane passing through the end of the opening 1% adjacent to the opening 12-6. 'lhe larger portion of the opening 12? is disposed on the side of the plane A. opposite from the opening 126, and, correspondingly. larger portion of the opening 126 lies the side of the plane B opposite from the opening 1%. By reason of the provision of single row only of openings 2 arranged as hereinhetore described, the taclzs are prevented from escaping too rapidly from the drums 1 he drain 22 connected at its ends to disks and 28 journaled in the main frame of the machine. The disks are extended radially beyond the periphery of the rotary drum or distributor 22 and are provided with inwardly projecting flanges 30 and 352 to which is connected for rotationwvith the drum a screen as enclosing the drum. The primary function 01? the screen 34 is to remove from the tacks Which pass therethrough any foreign material Whic may not have been separated therefrom in the magazine at in order that the tacks when delivered to the assorting stations shall be free from foreign material which might intert'ere with the proper :t'unctioning of the assorting mechanism or occasion breakage of some of the parts oi? the machine. It may be noted. however. that the rotary drum 252 will separate from the tack any object so large as not to pass through the comparatively small openings 24, and it is further to be noted that the screen 3% supplements tie action of the drum in insuring a unitorm distrihution of the fasteni to the assorting stations The foreign material vered from the machine by a chute 36 to which it passes through the open delivery ends of the drum 22 and scr and by which is conseparated from the tacks is del.
veyed to a receptacle 37.
The tacks as thev fall troni the drnniQZ conducted to the asserting stations 2 by non to he described. in do means comprises oppositely incl 1 slides rmed to present alternating rid 39 and channels ll) l). the latte being slotted greater tha the diameter of tire less than the d' a re tacks but i i tack heaos so that the teens as they tall from the drum on the slides group themselves the channels 410 supportcd by their heads in the Walls of the is clearly appears from the dr ..i
R the slides 38 are a n k of an inverted V the apex of i a positioned in the vertical plane of the axis of the drum There is thus prov'ded "W0 strnction to that at the right and the as-' sorting mechanism and other parts onone side of the machine are similar to those on the other side. *Consequcntly, a description of the parts on one side oi the machine will sntiice for both.
To counteract the tendency of the tacks to group themselves in the channels 40 ot' e slides 38 with their heads riding on each other and to arrange the tacks properly in the channels, I provide a picker 42 opertivcly associated with each of the channels it) and acting to engage the head or other portion of any tack which by reason of riding on the head of a preceding tack or for other reason is elevated to greater extent from the slot ot the channel than are the tacks which are properly located in the channel. The pickers e32 are mounted in collars from one end to the other ot the machine and each is arranged to yield rela 'ively to its collar 4:3 by means of a spring so interposed between an enlarged portion oi? the picker 4 and the bottom of the recess in the collar iv iich receives the picker. The frame of the machine is curved outwardly at 8 to provide a space in which the picker may be operated. "he channels ll) of the slides 38 constitute ra'ce'ii 'ays irhicli convey the tacks downwardly from the drum 22 toward the assorting stations V "lh. tac s pass down the channels -10 to the means may be caused to remove the tack'carrier different iined by their lengths, means i tor effecting change in therelaof the tack carrier and the path Such oi selecting means.
the invi -tion herein illust chosen to 001 attract the selectin the form of a her extended ely of the 'i'lir'ection of movement of a the channels 4:0 and parallel to -r 50and provided with un ually pro'ecting selecting portions 62 and respectively with selecting locaions5-l and 56 and to move the carrier 50 o to carry the notch 52 from a receiving the eliecte'd but in the location in aligmnent with the channel l0 of the raceway to selecting locations 54 and 56 to present the tack suspended by its head from the notch in operative relation to the selecting means.
The selecting bar is o erated in a fixed path transversely of the direction of movement of the tack carrier by rotation of the shaft 51 by which it is carried. The path of movement of the selecting means manifestly is nearer the tack carrier 50 in the direct-ion of the lengths of the tacks dependent from the tack carrier at the selecting location 56 which is aligned with the longer projection 64 of the bar 60 than at the ecting location 54 which is aligned with the shorter projection 62 of the bar 60. When, therefore, the tack carrier 50 'is moved so as to carry the notch 52 from selecting location 54 to the selecting location 56, the notch 52 which positions the tack relatively to the selecting bar 60 is caused to approach the path of movement of the selecting bar in the direction of the length of the tack. The projection 62 of the selecting baris spaced from the upper surface of the tack carrier 50 at the selecting location 54 by a distance less than the length of the longer tacks but greater than the length ofthe shorter tacks, the operation of the tack carrier 50 and the bar 60 being so timed that the bar is moved by the carrier in the direction indicated by the arrow (Fig. 3), that is, from the open. side of the notch 52 toward its closed side at the time when the notch 52 arrives at the selecting location 54. From the foregoing it will be understood thatif the tack in the notch 52 of the carrier 50 is a long one, its point will be en aged by the rojection 62 of the bar 60 and it will be pus ed from the carrier. If, however, the tack is a short one it will not be engaged the projection 62 of the bar but will be conveyed b the carrier to the selecting location 56 whi e the shaft 51 is completing arevolution into position to be engaged by the projection 64: of the ,bar 60 when it is again moved past the tack carrier 50, the projection 64 of the bar being 5 aced from the carrier50 by a distance less tlian the length of the shortest tacks being operated .upon and operating to remove from the tackcarrier any tacks which are not discharged therefrom at the selecting location 54. The. bar 60 is formed with an extreme depression 63 in the vertical plane of the channel 40 whichinsures that the tacks in the raceway. will'not be struck by the selecting bar in its movement. I
Both the tack carrier 50 and the tack selecting bar 60 are preferably and as herein illustrated extended transversely of the channels 40 fromend to end ofthe machine and. both of such members are operatively related to all of the channels. Each of said members may be said to comprise a plurality of like colligate sections one of which is associated with each of the assorting stations 2. The bar 60 is thus formed with alternating longer and shorter projections 62 and 64. As clearly shown in Fig. 3, the tack carrier is slidably mounted on a brace 65 projecting laterally from the machine frame, and the notches 52 are formed in an angular portion 66 of the carrier extending upwardly in the plane of the raceways.
A plate 67 pivoted to the frame of the machine at 68 overlies the channels 40 at their delivery ends and serves to prevent any of the tacks from being thrown upwardly from the channels 40 or the notches 52 either by engagement of the selecting bar 60 therewith or otherwise.
Preferably, the long tacks removed from the tack carrier 50 at the selecting locations 54; are collected in a common receptacle which should manifestly be separate from that in which are collected the shorter tacks removed from the carrier at selecting locations 56. To this end the tacks as they are discharged from the presenting means are caused to fall into hoppers 70 which'are alternately formed with floors 72 arranged to direct the tacks into a receptacle Tel and with floors 76 constructed to direct the tacks into a receptacle 78 constructed as a part of or located adjacent to the receptacle 74.
The operating means for the machine is as follows. Carried by the shaft 51 on the right hand side of the machine (Fig. 1) are tightand loose pulleys designated together by the reference numeral 82, and endless bolts 84: and 86 are provided for transmit ting the movement of the shaft 51 to the rotary drum 22' and the magazine l respectively. ()n the opposite end of the shaft 51 is mounted a gear 88 meshing with a gear 90 on a stud shaft 92 suitably journaled in the machine frame, and loosely carried by the stud shaft 92 is a cam disk 9% in the periphery of which is formed a cam slot in which engages a follower extending downwardly from the tack carrier 50 whereby the car-- rim is operated from a position in which the notches 52 are aligned with the channels 40 to' and from the selecting locations 56. Movement of the stud shaft 92 is transmitted to 'a corresponding stud shaft 95 on. the opposite side of the machine (Fig. 3) by an endless belt 96 which passes over pulleys on the respective studshafts. The shafts 44: on which the pickers are mounted are operated by endless belts 97 passing over pulleys carried by the shafts 441- and the stud shaft-s .92 and 95, respectively. Preferably, and as shown, a yielding connection 1s provided between the stud shaft 92 andthe tack carrier '50, said connection comprising a spring pressed plunger 98 mounted in the cam disk 94: and
struction is interposed to the movement of the tack -arrier the cam disk Set is permitted to more relatively to the stud shaft .92 and thus prevent breakage of the parts.
Maniiestly. the bar 60 may be formed with a number of selecting, portions variously spaced from the tack carrier 50 corresponding to the number of classifications of the tacks which it is desired to make. Thus, if it were desired to assort tacks in more than two groups, the selecting portions or projections 62 and Set of the bar 50 would be replaced by a greater number of selecting portions and the tack carrier would he moved to carry its notch 52 from the receivinn location to all the selecting locations.
