This'invention relates to improvements in Work supports and is illustrated herein as embodied in a fastening inserting machine of a. type used in' the manufacture and repairing of shoes. y

In the repairing of shoes the thickness of the work piece into which fastenings are inserted varies over a wide: range. Thesame machine is used, for example,both to attach m soles to shoes by all-around stapling and to attach top; lifits to heels of varying heights. It-is, accordingly, desirable to provide a work support, the height of which can beadjusted rapidly and with a minimum of labor. Since work supports used on metallic fastening inserting'machines, particularly when the work is. to be: performed off the last as in the case of-all-around stapling or nailing, are commonly provided with a clenching cavity the relation of which to the line of drive is critical, it is necessary so to construct the work support: that heightwise adjustment thereof will not affect the position of the clenching cavity transversely of the line of 251 drive; On. the other hand, for example to facthitate the" setting up of the machine, it is necessary to. provide means by which the posi tion of the clenching cavity can be adjusted transversely of the line; of drive.

invention to provide animproved work support" adapted for use in: fastening inserting machines ofi the-type used in the manufacture and repairing of? boots and shoes of such a character that its height can be more quickly and conveniently adjusted than is the case with: the constructions of: the prior" art. Itis a: further object. of the invention to provide anaimproved work support of such a nature .by the operator toward its work clamping position when the machine is at rest. As-illus- It is, accordingly, anobject of the present thatthe work support can be adjusted heigh*- struction; being of such a nature that the horn is held by the pawl and ratchet against movement away from its work supporting or clamping position (against downwardlmovement, as illustrated) but can be freely moved trated, the; pawl is provided with a tail or handle projecting outwardly so that it can be conveniently manipulated to release the sup port. This can be done by merely striking a light blow upon the tail of the pawlby downward movement of the hand of the operator. Such a construction perm-itsthe ad to each other and using his other hand to steady thewo'rk piece if necessary. .As he hits the horn to the desiredposition the ratchet clicks past the horn and holds the horn against downward movement.

In accordance with another feature ofthe invention, the illustrated machine: 1s provided with improved means for making, and

maintaining the adjustment of the clenching surface" of the horn'transversely ofthe line of drive at all times, regardless of the height wise, adjustment of the work support. For this purpose a horn supporting or bracket member, which is secured to the horn post for. rotation about the line of drive, is provided: with an upstanding rod surrounded by collarslidably mounted thereon and provided with a socket illustrated-as an undercut bayonet slot receiving aba-ll formed on the end of an adjusting screw threaded through the horn and normally secured'in p0- siti'onby a lock nut. Thecollar slides verti-" cally on the rod as the horn is adjusted heightwise and thus prevents transverse movement of the horn relatively to the horn support and accordingly relatively to'theline of drive. f

With' the aboveandotherobjects and features in view the invention willnowbe de-' 100 of drive.

scribed with reference to the accompanying drawings and pointed out in the claims.

In the drawings: I Fig. 1 is a side elevation of a staple inserting machine provided with a work support embodying the present invention;

The work support of the present invention is illustrated herein as embodied in a fasten ing inserting machine having staple forming and inserting instrumentalities of the character disclosed in Letters Patent of the United States No. 1,016,930, granted February 13, 19152 on an application filed in the name of William H. Borden to which reference maybe had 'for a fuller disclosure of --such parts of the machine as it is unnecessary to describe and illustrate herein. 'this machine comprises a column carrying at its upper end a head 12 provided with wire feeding rolls 14 (Fig; 2) from which a wire 16 is fed to a pair of knives 18 which sever "from it suitable lengths for the formation of staples. -The staples are formed from the In brief wire 16 by relative movement of an inside former 20 and outside formers 22, staples being driven through a nozzle 24 by a driver 26.

The staple forming and inserting instrumentalities are operated from a main drive shaft 28 to which power is transmitted by clutch mechanism 30 from a belt pulley 32.

1 The clutch mechanism 30 is controlled from a treadle 34 (Fig. 1) through a treadle rod 36, the arrangement being such that depression of the treadle 34 beyond a point determined by a lost motion connection 38 trips the clutch and causes the operation of the fastening inserting instrumentalities.

The machine is provided with a horn post 40 mounted for vertical sliding movement in I a sleeve 42 carried by a bracket 44 secured to the column 10, the horn post 40 being raised throughconnections 46 by the earlier portion of'the depression of the treadle 34 in a wellknown manner so that the work piece in which a'fastening is to be inserted (for ex 7 ample a shoe to which a sole or a half-sole is to be attached by all-around stapling or a shoe having a heel to which a top-lift'is'to be attached) is clamped under a relatively heavy spring pressure before the clutch is tripped.

Mountedat the top of the horn post 40 i for rotary movement about the line of drive is a bracket 50 provided with vertical ways 52 slidably receiving a downwardly extending stem 54 carried by a horn 56. The stem 54 of the horn 56 is provided with a ratchet 58 cooperating with alpawl 6O pivoted at 62 to the bracket 50 and yieldingly held in engagement with the ratchet 58 by a spring 64 so that the horn 56 can be moved upwardly while the machine is at rest without interference by the pawl but is held against downward movement except when the pawl 60 is manually released. The pawl 60 is provided with a substantially horizontal tail or handle 66 projecting outwardly so that the pawl 60 can be released from the ratchet 58 by a light blow struck on the tail 66 by a downward movement of the hand of the operator. 1 I

The-bracket 50 carries an upstanding rod 68 adjacent to the horn 56. Slidably mounted on the rod 68 is a collar 70. The collar 1 '70 is provided with an undercut groove 72 in the form of a bayonet slot/receiving a ball 7 4 formed on the end of a screw 6 threaded in a hole formed in the horn 56 and clamped inadjusted position by a lock nut 78 Thus 13,.

it will be seen that transverse movement of the horn 56 relatively to the bracket 50 is prevented by. engagement. ofthe screw '76 with the collar and heightwise movement of the horn is in no way interfered with. To

prevent the escape of the collar 70 from the rod 68 by excessive upward movement ofthe. horn 56 a collar '80 is secured to the upper end of the horn 56. When it is desired to adjust the position of the clenching cavity 82?. carried at the end of the horn 58, either in setting up the machine or otherwiseyit is only necessary to release the lock nut 78,

turn the screw 76 to make the desired adj ustment, and then tighten up thelock. nut. In this way the desired. critical adjustment of the clenching cavity relatively, to the line of drive can be easily made.

Assuming the work support to be insuch a position that the horn 56 is too high to re'.' ceive the work piece whichis to be presented to the machine, the operator strikes the'han dle 66 of the pawl 60 thus releasing the'pawl from the ratchet 58 so that'the horn descends to its lowermost position. Then he places the work piece on the horn 58, holding the work piece between the end. of the horn 58 and the nozzle 24 and at the same time grasping the portion of the horn .58 adjacent to the work piece with one hand so that he can move the horn and the work piece upward- 1y until the horn is spaced the desired distance below the nozzle of the machine. After the ho'rn has been adjusted in this manner he depresses the treadle 34, first causing the:

work piece to be clamped between'the horn 56 and the nozzle 24 and thereafter tripping the clutch thereby causing the insertion of a staple.

While the member 56 of the work support-- oftheillustrated machineis spoken of in this specification and the accompanying claims asa horn it should be understood that this-is merely as a matter of convenience and is n'ot'intended as a limitation. Obviously the invention is not limited in its scope to a construction in which the work carrying'memberis of a curved formation of the general Character herein disclosed and it is not intended that the claimsshall be construed as construction being such that the horn'isautomatically held by the pawl and ratchet againstmovement relatively to the horn carrier away from its work supporting position but can be freely moved by the operator toward its work clamping position when the machine is at rest.
