3 Claims. (CI. 26-68) This invention relates to fabric conditioning machines and more particularly to machines for returning fabrics to their originalsize after shrinking during a cleaning process.
In the process of dry cleaning, many cloths or fabrics have a tendency to shrink. This is particularly noticeable in window draperies where a very slight diiference in the length of one drapery will be very apparent. When one drapery is slightly longer than the other drapery or one is not shrunk to quite the same length as the other, it is very noticeable. The shrinkage of clothing is noticeable in coats and suits which have been cleaned repeatedly.
It is, accordingly, an object of this invention to provide a device for use in stretching fabric material and causing it to take a permanent set in the stretched condition.
Another object of the invention is to provide a device for stretching fabric material using steam to cause the material to assume a condition subject to stretching.
Another object of the invention is to provide a device whereby fabric material can be stretched and dried in the stretched condition whereby it will take a permanent set.
Another object of the invention is to provide a device for stretching fabric material whereby steam is forced through the fabric material and a blast of air is subsequently applied to the material to dry the material.
Another object of the invention is to provide a novel type of fabric stretching and drying device.
Another object of the invention is to provide a fabric conditioning device.
Another object of the invention is to provide a fabric stretching and conditioning device which will be simple and effective in operation and economical to manufacture.
With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing:
Fig. 1 shows a perspective view of our fabric condition ing device according to the invention;
Fig. 2 is a cross sectional view of our fabric conditioning device taken on line 2-2 of Fig. 1;
Fig. 3 is an enlarged view of the clamping device shown in Fig. 1;
Fig. 4 is a detailed view of a part of one of the pipes shown in Fig. l; and
Fig. 5 is an enlarged view of a part of the loading table legs.
Now with more specific reference to the drawing, in Fig. l, a conditioning device 1 is shown having a top 2 supported by legs 3 at 4. The legs 3 are welded to the rim 5 at 4: however. the legs could be made removable in a well known manner for storage and shipping purposes if such were desired. A screen mesh 6 is supported on the rim 5. The legs 3 are held together at the bottom by ice side braces 7 and end braces 8. The braces 7 and 8' can be connected to the legs 3 at 9 by welding, brazing, or other fastening methods but could be made with removable connecting means for storing and shipping purposes.
A tank 10 is disposed under the top 5. The tank 10 is' made up of sides 11 which are made of plates of steel or other suitable material and ends 12 of the same material. Rings 10a are attached to the sides of the side members 11 at 11a. These rings are provided for attaching the fabric material to be conditioned. Bottom member 13 is attached to the side member 11 at 14 and the sides- 11 are welded to the legs 3 at 15 and the ends 12 are welded to the legs 3 at 16. The entire tank slopestoward the end 17 and a channel 18 is provided in the bottom to carry away condensate. The channel 18 is made up of side members 19 welded to the bottom members 13'at 20 and a drain pipe 21 is disposed in the channel 18 whereby condensate from the tank can be conducted away.
The sides 11, ends 12, and channel 18 are all welded together to form an integral air and gas proof tank. Blower 30 is attached to one end 12 of'the tank at 31 by means of bolts 31a and a discharge opening 32 is provided whereby air from the blower 30 will be discharged into the tank 10. The blower may be a conventional centrifugal type blower having an impeller 33 driven by a motor 34. Suitable Wiring can obviously be provided with a switch disposed in a convenient location for access to the operator. Pipes 40 are supported in the tank on cross members 41 which may be made of angle iron and which are attached to the sides of the tank. The pipes 40 have caps 43 on one end thereof and are drilled in the bottom side by spaced holes 45. Pipes 40 are attached by means of elbows 46 to T 47 which may be connected to any suitable supply of steam. A suitable valve or means to control the flow of steam through the pipes 40 will be provided.
At one end of the table, the clamps 50 are attached. The clamps 50 are attached to the member 5 of the table at 51 and are made up of base member 52 and clamping member 53. The clampingmember 53 is pivotally connected to the base member 52 at 54 and connected to the handle 55 at 56. The handle 55 is pivotally connected to the link 57 at 58 and link 57 is pivotally connected to base 52 at 59. The transverse member 60 is supported on the clamping member 53 by bolts 61. The steam pipes 40 will be supported on the support member 41 by clamps 40a or other suitable clamping means.
When it is desired to return a window drapery or similar fabric member to its original size after it has been progressively shrunk by dry cleaning processes, one end of the fabric is clamped under the clamping bar 53 by elevating the handle 55. This will raise the transverse member 60 from engagement with the screen mesh 6. One end of the drapery or other fabric material is placed under the transverse member 60 and the handle 55 moves downward until the pivot point 58 moves below a line drawn through pivots 56 and 59. In this position, the clamp will be held down by toggle action. An operator then grasps the end of the material remote from the end clamped by the member 60 and exerts a tension thereon. The sides of the material can be attached to the rings 10a.
Loading tables 106 can be connected to the sides 11 by means of hinges 107. The loading tables are supported by means of the hinges 107 and the legs 108 which are pivoted to the bottom of the table at 109 and can be folded longitudinally against the bottom of the loading table in a position shown in Fig. 5. The loading tables can then be swung downwardly to the position 111 as shown in Fig. 2. These loading tables are provided to lay draperies or other fabric material on. preparatory to conditioning them.
If lateral stretching is desired, one operator can be stationed at either side of the table to grasp the sides of the material and exert a tension thereon. Steam is then admitted through pipes 40 until steam fills the tank 10. Then the blower 30 is started and air from the blower 30 forces the steam in the tank up through the wire mesh 6 and through the drapery material, thereby heating and dampening the material. During this step in the operation, the material is stretched. When the material is stretched to the size desired, the motor is allowed to continue to run and air from the blower flowing up through the fabric material will drive the steam and cause the material to take a permanent set.
The material to be conditioned can be laid on one of the loading tables 106 and removed therefrom to the screen mesh 6 and when the conditioning operation is finished, the drapery can be laid on the loading table 1% at the other side of the machine.
If a drying cycle is not desired, a constant flow of steam can be allowed into the tank and the blower started when a flow is desired through the cloth. A cloth cover 6a can be disposed over the top of the wire mesh upon which the goods to be stretched can be placed.
In the foregoing specification, we have set forth the invention in its preferred practical forms but we are aware that the structure shown is capable of modification within a range of equivalents without departing from the invention which it is to be understood is broadly novel as is commensurate with the appended claims.
