Description
- 2~ 3 Baclc~rourld of the Irlvention (1) Field of the Inven_ion This invention relates to a cementing press for attaching outsole~ to lasted footwear, wherein a counter-support receiving the out601e and two 5 presser member~ are moved relative to one another, oE which the one presser member acts on the heel portion and the other on the toe portion of the last, the counter-support consisting of pressure portions, which acGommodate themselves to the shoe bottom under pressure.
~2) Prior l~r A cementing press of the basic design is described in German Patent Application No. DT-OS 26 OZ 831. The pressure portions on this cementing press cons;st of pads arranged side by side, which extend over the toe and ball region as well as over the waist section of the shoe. Each of these pads is exposed to a pressure, so that when they are under pressure they conform 15 in their upper position to the shape of the shoe bottom. Because a relatively large nurnber oE pad~ are :required for this cementing press, a large expenditure rnust be made for these components. lVloreover, the basic press create~ a stepped surface over the end faces of the pads when they engage the shoe bottom initially which can lead to stepped imprints, especially on shoes of 20 high waists.

1LlL3 Summa~ oE the [nvention The present invention involves arranging the cementing press in euch a way that it achieves a more uniform pressing effect at a reduced cost.
~ccording to the invention the toe and ball region is provided with a freely-5 swinging rocker~assembly that serves as a counter-support. A Eulcrum extends transversely to the last within the toe and ball region and a rocker-assembly is provided with a locking means which is actuated be~ore the application of full pressure and before the rocker-assembly has settled in a position dictated by the shoe bottom laid thereagainst.
With this arrangement only one component is used as the pressure portion in the toe and ball region, namelyJ the freely-swinging rocker-assembly. Moreover, a uniform pressure can be produced practially over the whole of the shoe bottom by a cushlon placed in a well-known manner on the rocker-assembly, thus eliminating the pressure forming steps. ~ny 15 possible pressure differentials still existing on account oE the surface of the cushion and the surEace of the shoe bottom not being completely iclentical will merge into one another continually SO that the individual imprints frequently arising from the use of pads can be avoided.
To insure that the rocker-assembly can process large and small shoes 20 without the need of an individual adaptation of the cementing press in the toe and ball region (which could lead to different angular settings of the rocker-assembly to compensate for the position of the fulcrum of the rocker-assembly), a locking means is provided, which locks -the rocker-assembly in the position it has assumed before the application of the full bedding pressure.
25 Before arrival of the full bedding pressure, the rocker-assembly, to a large extellt, i~.cle~perldent of the po~3ition oe it~ eulcrum to the toe~ and ball reg~ion of the shoe to be pr~ces.sed) practically abuts the shoe hottom so that the rocker-assembly stays put by the locking actlon and that it withstands the full bedding pressure in the attained position without moving.
It is known from German Patent Application No. DE~OS 26 36 511, in connection with the basic cementing press, to use a rocker-assembly as a counter-support within the toe and ball region. This rocker-assembly, however, is adjustable by hand to a particular angular position, which is suited for each type of shoe. The patent application does not teach a 10 freely-swinging rocker-assembly.
Appropriately, the locking means are formed as arms extending away from the rocker-assembly in the direction of the bedding pressure.
Upon tipping, the rocker-assembly and the arms effect a swinging movement and engage in racks, which, when the shoe bottom is laicl against the rocker-15 assembly, effect a movement towards the rocker-aæsembly and thus secure the arms. Pads may be used with this cementing press to press againat the waist region of the shoe bottom. These pacls press against the racks in their res-t position, which are then released when the pads move the racks thus abutting the arms. The arms are then locked as in the manner 20 described above.
The rocker-assembly is normally provided with a yieldable cushion.
The cushion is disposed with its side facing the waist as a yieldable underlay substantially softer than the cushion. If the tilting of the rocker-assembly (particularly when it is used to process larger si~ed shoes) deviates slightly 25 from the shoe bottom, a small gap can occur between the cushion and the toe of the shoa. The yieldable underlay, however, can be cornpressed a little with the initiation of the f'ull hedcling pressure, whereby the cushion is tilted slightly compared with the rocker-assembly to compensate the angular position of the rocker-assembly described above. In this way, 5 a uniform bedding~ pressure is produced over the whole of the shoe bottom.

Brief Description of the Drawin~
The objects and advantages of the present invention will become more apparent when viewed in conjunction with the following two figures, which are side elevational views, partially in cross~section, of the press 5 of the present invention. Two different shoes are shown in the Figure~
illustrating the versatility of the equipment.
~7 ~
1~ cr~on oE the ~e~e ecl F.mb diments Referring to the clrawings in detail, and particularly to Figure l, a shoe 2 is placed on the one end on a support 4 and on the other end on a cushion 5. The support 4 supports the shoe 2 directly ahead of it~ heel 5 3. The support 4 can be set in a known way by means of a bolt 6 to any optional, required height. In thifl way, the cementing press is adapted individually to the form of the type of shoe to be processed. The shoe 2 lies in its toe and ball region upon the cushion 5, which is carried by a rocker-assembly 7.
The cushion 5 consists of rubber and therefore possesses the required yieldingness for the adaptation to the shoe bottom 8. The rocker-assembly 7 is pivoted by means of a fulcrum 9. At its side away from a shoe 1, shown as a smaller shoe in the Figure 1, wherein the rocker-assembly 7 in its rest position is supported by the plunger 10, which applies pressure via 15 spring 11 onto adjusting screw 12. By means of this adjusting screw 12 the plunger 10 can be set to any desirable height. The spring 11 allows the rocker-Elssembly 7 to twist downwards a little at its end away from the 3hoe 1 upon exertion of bedding pressure against cushion 5.
In orcler to expose the shoe 2 to the pressure required for attaching 20 an outsole 13, a pair of pressure members 14 and 15 are provided. According to the length of the shoe to be processed, the presser member 15 is adjustably arranged in the longitudinal direction of shoe 2. The presser member 15 has the pad 16 at its lower end which presses onto the upper leather of the shoe 2 to be processed. The use of the pad 16 eliminates any danger 25 that the upper leather of the shoe 2 can become damaged when pressure ~.... ,~ , i9 e~{erted. The presser member 14 pxesses via foot 17 onto the last 18.
For illustrative purpo~es, a respectively smaller last 19 is shown ~ogether with the shoe 1 outlined in Figure 1.
The shoe to be processed is first placed on the support 4 and the 5 cushion 5 as particulari~ed above, where it takes up a position as shown in the illustration. Then the whole mechanism below the presser members 14 and 15 (or 15') is moved upwardly, so that the shoe 2 (or 1) i6 seated against the pad 16 (or 16') and the last 18 (or 19) contacts the foot 17 of the presser member 14. Further upward movement of the said mechanism lO causes the initiation of a bedding pressure that is required for attaching the outsole 13. The cementing press has a control through which a signal is ~iven when a certain still relatively low pressure is attained. Upon receipt of the signal, the pads 20 to 23 begin an upward movement. The pads 20 to 23 are arranged directly side by side and are operated by hydraulic 15 pistons via plungers 24 to 27 with each plunger being pxovided with its own hydraulic piston. For the sake of clarity of the illustration, only hydraulic piston~ 28 and 2~ are drawn. The pads 20 and 23 are arranged sicle by side and are supported at the one side by the gui~le 30 ancl at the other side by the plate 31. These construction elements are mounted to 20 the frame of the cementing press in a conventional manner.
The pad 20 is provided with a special plunger, namely the plunger 24, which presses against the rack 32 that is pivoted at one end. The rack 32 is pivoted at its right-hand end around a fulcrum 33. In the region of its left-hand end, the rack 32 is supported ~y a compression spring 25 34. With the pad 20 in the rest position, the plunger 24 presses against the r ack 32, thus fixecUy holding it. Etowever when the pads 20 to 23 c~re raised by the signal a~ de~cribed above, then plunger 24 releases rack 32, so that its left-hand end can move upward.s by the force of the compression spring 34 and rotate the rack around its fulcrm 33. The rack 32 with its S serrations 35 comes then into engagement with the serrations 36 oE the arm 37, which is combined solidly with the rocker-assembly 7. The arm 37 responds to any swinging movement of the rocker-assembly 7 effected around its fulcrum 9.
The meshing of the serrations 35 and 36 takes place as the pads l0 20 to 23 are moving upwardly, that is, while the shoe bottom 8 is being exposed to only a relatively low pressure via the presser member 15 and the cushion 5. On account of this the rocker-assembly 7 has at this stage the ten~ency (with regard to its postion above the cushion 5) to adapt itself to the shape of the shoe bottom 8. Serrations 35 and 36 then mesh IS so that arm 37 and the rocker-assembly 7 can no longer rotate about its fulcrum 9. Any stresses put onto the rack 32 (e . g . pull or push) are taken up by fulcrum 33. With the end faces of the pads 20 to 23 abutting outsole 13, the full pressure then builds up against the shoe 2 (or 1) without the rocker-assembly 7 being able to rotate about its Eulcrm 9. I)epending 20 on the position of the pressure member 15 tor 15') relative to the fulcrum 9 of the rocker-assembly 7, a torque may be exerted on the rocker-a~sembly, that is, a twisting motion of the rocker-assembly 7. Cushion 5, however, cannot move because of the interlocking of the serrations 35 and 36. When ~ull pressure builds up upon the cushion 5 and the end faces of the pads 25 20 to 23, the outsole 13 is then finally attached to the shoe 1 (or 2) .
, ~.., Drawn also into Figure 1 in a clotted representation manne~ is a wedge 38 situated on the rocker ass0mbly 7, 'l'he wedge 38 may be inserted then on an optional basis if there is a possibility that the left-hand end of the rocker-assembly 7 iB likely to yield a little under the downwarcl 5 pressure exerted by the presser member 15' onto along shoe 2. When the wedge 38 i9 inserted for the processing of shoes of that type, then a position i9 created upon insertion of cushion 5, whereby it abuts the rocker-assembly 7 at it left-hand end and the wedge 38 at its right-hand end, so that a small gap is formed in the central region of the cushion 10 5 in relation to the rocker-assembly 7. This gap has been omitted from the drawing for reasons of clarity. Thus, the effect is established that because of the substantially greater softness of the material of the wedge, it i6 then compre~sed when full pressure is applied onto, thus establishing in effect a position of the cushion 5 in relation to the rocker-assembly 7, 15 as it is represented in the illustration. This means then that the cushion 5 adapts itself at a later stage to the correct position of the shoe bottorn 8. Previously it was already established under the oblique setting~ of the cushion 5 effected by the wedge 3B in re~pect to the rocker-as~embly 7, that the cushion 5 takes up in itself, a position in which it is brought 20 closer toward the toe of the shoe from the center of the shoe. Thi~s is deliberate in order to give the cushion 5 the final, correct and necessary posltion at a later stage when the pressure is fully built up.
By using the rocker-assembly 7 (which adapts automatically to the position of the shoe bottom 8) together with the cushion 5, a very uniform 25 spread of pressure is achieved over the toe and ball region, 80 that the ~.,,~
part~i of the ~;hoe are uniEormly glued together a~; ~huwn ~JirnilElr:ly in r'igure 2.
