DESCRIPTION OF PREFERRED EMBODIMENTS
A power press is generally in~ te~3 by refer~llce 20 in figures 1, 2 and 10. The power press 20 includes a press bed 22 which acts as a base for the power press 20. A lower ironing panel 24 is secured to the press bed and has a generally horizontal upper face 26.
A press arm 28 is pivotably mounted to the press bed 22 by means of a pivot pin 30 extending through the press arm 28 and journalled into supports 32 e~ct~n~1ing upwardly on both sides of the press bed 22.
An upper press soleplate 34 is secured to the press arm 28 and movable therewith between an open position shown in dashed outline in Figure 2 and a closed position shown in solid outline in Figure 2. In the closed position the upper press soleplate 34 is adjacent the lower ironing panel 24. In the open position the upper press soleplate 34 is away from the lower ironing panel 24 to allow garments to be removed from or placed on the lower ironing panel 24.
A spraying device 36 is mounted adjacent an outer end of the upper press soleplate 34. The spraying device 36 includes a nozzle 38 generally directed at the lower ironing panel 24.
An actuator indicated generally by reference 40 in Figure 2 acts between the press bed 22 and the press arm 28 to pivot the press arm 28 and upper press soleplate 34 between the open and closed positions.
The activator 40 includes a motor 42 connected to a first shaft 44 which is rotatable by the motor 42. A second shaft 46 is adjacent and generally axially aligned with the first shaft 44. The second shaft 46 is rotatably coupled to the first shaft 44 by a first coupling member 48. The firstcoupling member 48 includes some clearance to allow some axial movement between the first shaft 44 and second shaft 46 in the direction of arrows 50.
Any suitable coupling may be used for the first coupling member 48.
Illustrated in Figure 2 is a 'U' shaped slot in the end of the first shaft 44 which receives a generally rectangular tongue at the corresponding end of the second shaft 46. Other suitable couplings such as cooperating splined members or a socket which registers with a similarly shaped prong.
A third shaft 52 is rotatably coupled at an inner end 54 to a second end of the second shaft by a swivel coupling 56 such as a 'U' joint. The swivel coupling 56 allows the second shaft 46 to rotate the third shaft 56 despite some angular misalignm~nt therebetween. The third shaft 52 is threaded at least part way along its length as shown by reference 58.
The threaded part 58 of the third shaft 52 threadedly engages a threaded boss 60 pivotably mounted to the press arm 28 to move the threaded boss 60 along the third shaft 52 and in turn cause the press arm 28 to pivot relative to the press base 22 in the direction of the arrows 62 in response to rotation of the third shaft 52.
The motor 42 is activated by depressing an activating switch 64 to move the activating switch 64 to a first position to cause the motor 42 to rotate in a first direction in which the press arm 28 and upper press plate 34 21g~813 move toward the closed position. A first limit switch 66 senses when the press arm is in the closed position to stop rotation of the motor 42.
ReleAsing of the activating switch 64 allows the activating switch 64 to 5 move to a second position which causes the motor 42 to rotate in a direction opposite the first direction thereby moving the press arm 28 and upper press plate 34 to move toward the open position. A second limit switch 68 mounted between the press bed 22 and press arm 28 senses when the press arm 28 and upper press soleplate 34 reach the open position to stop rotation 10 of the motor 42.
A pressure sensor generally indicated by refelel~ce 70 is provided to activate the first limit switch 66 when a predetermined force has been ~t~ine-l between the upper press soleplate 34 and lower ironing panel 24. In 15 this manner the pressure exerted on a garment placed between the upper press soleplate 24 and ironing panel 34 is determined by the pressure sensor 70 rather than by the thil~kness of the garment.
The pressure sensor 70 includes a disc 72 extending substantially 20 about and secured to the second shaft 46. The disc 72 is movable with the second shaft 46. The pressure sensor 70 further includes a spring abutment 74 secured to the ironing press bed 22 and exten~ling subst~nti~lly about the second shaft 46. The second shaft 46 is slidable through the spring abutment 74.
A spring 76 extends between the disc 72 and the spring abutment 74.
The spring 76 allows movement of the disc 72 toward the spring abutment 96 in response to pressure between the upper press soleplate 34 and the lower ironing panel 24 which is tr~nsmitted along the second shaft 46. As 30 the disc 72 moves toward the spring abutment 74 it will eventually strike the first limit switch 66 to activate the first limit switch 66 at a force predetermined by the length and spring constant of the spring 76.
A manually operable safety lever 78 in Figures 1, 2, 3 and 4 is mounted to the press bed 22 to enable the upper press soleplate to be moved away from the lower ironing panel should the motor 42 fail to operate. The safety lever 78 acts against an outer end 80 of the third shaft to press the 5 third shaft 52 and second shaft 46 toward the first shaft 44 against the force of the spring 76. A handle 82 in Figures 2 and 4 is provided as part of the safety lever 78 to assist in ~ct~l~hng the safety lever 78.
The spraying device 36 and its operation are further illustrated in 10 Figures 5 through 10. The spraying device 36 has a water reservoir 84 with a filler orifice 86. A cylinder 88 fluidly communicates with the water reservoir 84 through an inlet 90. A first one way valve 92 is mounted between the water reservoir 84 and the cylinder 88 to permit fluid (i.e. water) flow from the water reservoir 84 into the cylinder 88 while inhibiting fluid flow from 15 the cylinder 88 back into the water reservoir 84.
A nozzle 90 fluidly communicates with the cylinder 88 through an outlet 92. A second one way valve 94 is provided between the cylinder 88 and the nozzle 90 to permit fluid (i.e. water) flow from the cylinder 88 into 20 the nozzle 90 while inhibiting fluid (i.e. water or air) flow from the nozzle 90 back into the cylinder 88.
A piston 96 is slidably received by the cylinder 88. A piston activator generally indicated by reference 98 is provided and is responsive to 25 movement between the press arm 28 and the press bed 22 to move the piston 96 into the cylinder 88 as the press arm 28 begins to move from the open position to the closed position.
The piston activator 98 includes a base member 100 to which the 30 cylinder 88 is mounted and which includes a sliding fork 102 mounted thereto and slidable therealong. A piston rod 104 extends between the piston 96 and the sliding fork 102. A cable 106 analogous to a bicycle cable is mounted in the base 100 and has a first end 108 secured to the sliding fork - 21948~3 102 for causing the slit1ing fork 102 to move toward the cylinder 88. A second opposite end 110 of the cable 106 opposite the first end 108 is secured to an actuating arm 112 in Figure 10.
A spring 114 extends between an inner end of the cylinder 88 and the piston 96 to urge the piston 96 out of the cylinder 88.
The actuating arm 112 is pivotably mounted to the press bed 22. A
rotating cam 116 in Figure 10 is mounted to the activating arm 112 and rotatable therewith.
A swing cam 118 is secured to the press arm 28 and pivots therewith.
The swing cam 118 has a projection 120 which presses against a corle~onding projection 122 on the rotating cam 116 as the press arm 28 is initially moved from the open position toward the closed position. Pressure of the swing cam 118 against the rotating cam 116 causes rotation of the rotating cam 116 and in turn the actll~ting arm 112 to pull the cable 110 and in turn slide the sli-ling fork 102 toward the cylinder 88.
Releasable engaging means are provided between the piston rod 104 and the sliding fork 102 such as prongs 120 in Figure 8 which extend radially outwardly from opposite sides of the piston rod 104. The piston rod 104 is rotatable about its axis between an engaged position in which the prongs 120 extend across sides 122 of the sli~ling fork 102 and a disengaged position in which the prongs 120 line up with a slot 124 in the sli(ling fork 102. In the engaged position, the prongs 120 abut against the sliding fork 102 to cause the piston rod and in turn the piston 96 to move into the cylinder 88 in response to movement of the sli~ling fork 102 toward the cylinder 88. In the disengaged position the prongs 120 line up with the slot 124 to avoid being acted upon by the slit1ing fork 102. In this manner S~ldyillg can be turned on or off by the operator of the power press 20.
-219 18~3 Rotation of the piston rod 104 about its axis between the engaged and disengaged position may be effected by a handle 126 engaging a groove 128 in the piston rod 104.
The above description is intended to be interpreted in an illustrative rather than a restrictive sense. Variations to the structure described above may be apparent to those skilled in such apparatus without departing from the spirit and scope of the present invention as fl~fine-l by the claims set outbelow. It is intended that any variations within the spirit and scope of the invention as ~l~fin~d by the claims be deemed to fall within the scope of this patent.
The activator 40 includes a motor 42 connected to a first shaft 44 which is rotatable by the motor 42. A second shaft 46 is adjacent and generally axially aligned with the first shaft 44. The second shaft 46 is rotatably coupled to the first shaft 44 by a first coupling member 48. The firstcoupling member 48 includes some clearance to allow some axial movement between the first shaft 44 and second shaft 46 in the direction of arrows 50.
Any suitable coupling may be used for the first coupling member 48.
Illustrated in Figure 2 is a 'U' shaped slot in the end of the first shaft 44 which receives a generally rectangular tongue at the corresponding end of the second shaft 46. Other suitable couplings such as cooperating splined members or a socket which registers with a similarly shaped prong.
A third shaft 52 is rotatably coupled at an inner end 54 to a second end of the second shaft by a swivel coupling 56 such as a 'U' joint. The swivel coupling 56 allows the second shaft 46 to rotate the third shaft 56 despite some angular misalignm~nt therebetween. The third shaft 52 is threaded at least part way along its length as shown by reference 58.
The threaded part 58 of the third shaft 52 threadedly engages a threaded boss 60 pivotably mounted to the press arm 28 to move the threaded boss 60 along the third shaft 52 and in turn cause the press arm 28 to pivot relative to the press base 22 in the direction of the arrows 62 in response to rotation of the third shaft 52.
The motor 42 is activated by depressing an activating switch 64 to move the activating switch 64 to a first position to cause the motor 42 to rotate in a first direction in which the press arm 28 and upper press plate 34 21g~813 move toward the closed position. A first limit switch 66 senses when the press arm is in the closed position to stop rotation of the motor 42.
ReleAsing of the activating switch 64 allows the activating switch 64 to 5 move to a second position which causes the motor 42 to rotate in a direction opposite the first direction thereby moving the press arm 28 and upper press plate 34 to move toward the open position. A second limit switch 68 mounted between the press bed 22 and press arm 28 senses when the press arm 28 and upper press soleplate 34 reach the open position to stop rotation 10 of the motor 42.
A pressure sensor generally indicated by refelel~ce 70 is provided to activate the first limit switch 66 when a predetermined force has been ~t~ine-l between the upper press soleplate 34 and lower ironing panel 24. In 15 this manner the pressure exerted on a garment placed between the upper press soleplate 24 and ironing panel 34 is determined by the pressure sensor 70 rather than by the thil~kness of the garment.
The pressure sensor 70 includes a disc 72 extending substantially 20 about and secured to the second shaft 46. The disc 72 is movable with the second shaft 46. The pressure sensor 70 further includes a spring abutment 74 secured to the ironing press bed 22 and exten~ling subst~nti~lly about the second shaft 46. The second shaft 46 is slidable through the spring abutment 74.
A spring 76 extends between the disc 72 and the spring abutment 74.
The spring 76 allows movement of the disc 72 toward the spring abutment 96 in response to pressure between the upper press soleplate 34 and the lower ironing panel 24 which is tr~nsmitted along the second shaft 46. As 30 the disc 72 moves toward the spring abutment 74 it will eventually strike the first limit switch 66 to activate the first limit switch 66 at a force predetermined by the length and spring constant of the spring 76.
A manually operable safety lever 78 in Figures 1, 2, 3 and 4 is mounted to the press bed 22 to enable the upper press soleplate to be moved away from the lower ironing panel should the motor 42 fail to operate. The safety lever 78 acts against an outer end 80 of the third shaft to press the 5 third shaft 52 and second shaft 46 toward the first shaft 44 against the force of the spring 76. A handle 82 in Figures 2 and 4 is provided as part of the safety lever 78 to assist in ~ct~l~hng the safety lever 78.
The spraying device 36 and its operation are further illustrated in 10 Figures 5 through 10. The spraying device 36 has a water reservoir 84 with a filler orifice 86. A cylinder 88 fluidly communicates with the water reservoir 84 through an inlet 90. A first one way valve 92 is mounted between the water reservoir 84 and the cylinder 88 to permit fluid (i.e. water) flow from the water reservoir 84 into the cylinder 88 while inhibiting fluid flow from 15 the cylinder 88 back into the water reservoir 84.
A nozzle 90 fluidly communicates with the cylinder 88 through an outlet 92. A second one way valve 94 is provided between the cylinder 88 and the nozzle 90 to permit fluid (i.e. water) flow from the cylinder 88 into 20 the nozzle 90 while inhibiting fluid (i.e. water or air) flow from the nozzle 90 back into the cylinder 88.
A piston 96 is slidably received by the cylinder 88. A piston activator generally indicated by reference 98 is provided and is responsive to 25 movement between the press arm 28 and the press bed 22 to move the piston 96 into the cylinder 88 as the press arm 28 begins to move from the open position to the closed position.
The piston activator 98 includes a base member 100 to which the 30 cylinder 88 is mounted and which includes a sliding fork 102 mounted thereto and slidable therealong. A piston rod 104 extends between the piston 96 and the sliding fork 102. A cable 106 analogous to a bicycle cable is mounted in the base 100 and has a first end 108 secured to the sliding fork - 21948~3 102 for causing the slit1ing fork 102 to move toward the cylinder 88. A second opposite end 110 of the cable 106 opposite the first end 108 is secured to an actuating arm 112 in Figure 10.
A spring 114 extends between an inner end of the cylinder 88 and the piston 96 to urge the piston 96 out of the cylinder 88.
The actuating arm 112 is pivotably mounted to the press bed 22. A
rotating cam 116 in Figure 10 is mounted to the activating arm 112 and rotatable therewith.
A swing cam 118 is secured to the press arm 28 and pivots therewith.
The swing cam 118 has a projection 120 which presses against a corle~onding projection 122 on the rotating cam 116 as the press arm 28 is initially moved from the open position toward the closed position. Pressure of the swing cam 118 against the rotating cam 116 causes rotation of the rotating cam 116 and in turn the actll~ting arm 112 to pull the cable 110 and in turn slide the sli-ling fork 102 toward the cylinder 88.
Releasable engaging means are provided between the piston rod 104 and the sliding fork 102 such as prongs 120 in Figure 8 which extend radially outwardly from opposite sides of the piston rod 104. The piston rod 104 is rotatable about its axis between an engaged position in which the prongs 120 extend across sides 122 of the sli~ling fork 102 and a disengaged position in which the prongs 120 line up with a slot 124 in the sli(ling fork 102. In the engaged position, the prongs 120 abut against the sliding fork 102 to cause the piston rod and in turn the piston 96 to move into the cylinder 88 in response to movement of the sli~ling fork 102 toward the cylinder 88. In the disengaged position the prongs 120 line up with the slot 124 to avoid being acted upon by the slit1ing fork 102. In this manner S~ldyillg can be turned on or off by the operator of the power press 20.
-219 18~3 Rotation of the piston rod 104 about its axis between the engaged and disengaged position may be effected by a handle 126 engaging a groove 128 in the piston rod 104.
The above description is intended to be interpreted in an illustrative rather than a restrictive sense. Variations to the structure described above may be apparent to those skilled in such apparatus without departing from the spirit and scope of the present invention as fl~fine-l by the claims set outbelow. It is intended that any variations within the spirit and scope of the invention as ~l~fin~d by the claims be deemed to fall within the scope of this patent.
