PROCESS AND MACHINE FOR CREASING.

Application filed JanuaryfiO, 1922. Serial No. 532,820.

To ill i /.007 it may concern:

Re i t known that we, CLAUDE H. HALL a d Gunner lZNUDSEN, citizens of the United I and residents of'Baltimore city, in the Ftate of h laryiand. have invented a new lrocos; and hilachine for creasing, of which the following is a specification.

our in ention relates to improvements in reasing. and has for its object an improved in process reasing and a machine for accomplishing the same.

lu the ordinary method of creasing, dry heatin means is used, such as a table heated flame, which is not constant heat at a pre-determined temperature, but some times get so hot as to burn the fabric, which with mohairsand other stiff fabrics does not give the sustained crease desired. To overcome this difiiculty is one of the objects of our invention.

A further object of our invention is the pro ess and means for accomplish ng the turning, soften ng, holding turned and drying an edge of fabric.

30 operated upon at a constant and pre-determined temperature.

Our invention consists of the novel process, method and appliances for making permanent creases in fabric, as hereinafter described. the machine of which is illustrated in the accompanying drawings, but it is understood that changes variations and modifications may be resorted to which come within the scope of the claims hereunto appended.

In the drawings of the herein described embodiment of our invention, Figure 1 is a side view in section taken through 1-1; Fig. 2, is a plan view. Fig. 3, is an enlarged view of a portion of the machine taken through 3-3 and Fig. 1, is an enlarged view in elevation of the treadle looking mechanism.

Similar numerals refer to similar parts throughout the several views:

1 is the table, the back of which forms a steam jacket 2. Within steam jacket 2 is auxiliary steam passage 3. 4 are orifices connecting with auxiliary steam passage 3 and directing the steam from said passage towards the creasing to be done.

A further object of our invention i's'the v :3 is a die over which the creasing is done. 5 are the edge turning dies, said dies being (flIl'lGCl by ross heads 7 operating between guides 8. 9 is the scroll plate in which are cam slots 10 and circular slots 11, in which work cap screws 12 to hold the scroll plate in place. The lateral motion of the scroll plate being confined by rollers 13 operating on studs secured to table 1. 141 is a handle on thescroll plate.

()n cross heads 7 are pins 15 carrying rollers 16. Rollers 16 are operated by cam slots 10 upon a circular motion of scroll plate 9 operated by handle 14, thus operating the edge turning dies to andfrom the work operated upon. 7

Die 5 is carried by arm 17 journalled to the table and ha handle 18 for operating. Ann 17 is normally'kept'open as shown in by spring 19. 20 are clamping bolts operating through cross heads 7 which cross: heads are provideo with slots to permit of movement with reference to said bolts. Bolts: are secured to equalizing bars 21, which bars are operated by tension rod 22. 23 is the foot lever fulcrumed at 24C'and operates tension rod 22, and is held down in clamped position by catch 25 and is kicked out of locked position by foot ki'ck off 26. 27 is a bumper. 28 is a-sprin'g tending to maintain foot lever 23 in up position, thereby releasing the clamping bolts 20.

33 is a steam valve admitting auxiliary steam passage 3 and through the orifices as desired. 29 is the main steam supply one branch going to valve 33 and another branch going into jacket 2 to a point well within the same. is a drain from the steam jacket which is connected with a drain from the steam line and goes to trap 31.

are gauges between which the fabric to be operated upon is placed.

The operation of our invention is as follows The fabric is placed between gauges 32. By means of handle 18, die 5 is brought down on the fabric pressing it on to table 1 which is maintained at a constant pre-desteam into of handleadmitted through valve 33, steaming the fabric. then by means of lever 23 and bolts 20, dies 6, clamp the fabric under and over the edge of die 5. forming the crease in the fabric previously softened by the steam treatment. The fabric is held in this latter position until thoroughly dried.

Having thus described our invention. what we claim and desire to secure by Letters Patent is l. The process of creasing consisting of turning the edge of a fabric and pressing the same, maintaining said fabric at a predetermined temperature above operating room temperature and while being so pressed admitting steam on to said fabric for a brief period of time.

2. In combination in a creasing machine. a steam jacketed table carrying means for creasing goods. creasing means carried by said table, and means of admitting steam directly upon the goods while in the creasing means.

3. In combination in a creasing machine, a steam-jacketed table carrying means for creasing goods, creasing means carried by said table. and means of admitting steam directly upon the goods while in the creasing means consisting of perforations in said table through which steam may pass communicating with a steam supply.

4. In combination in a creasing machine. a steam-j acketed table, creasing means carried by said table, means of admitting steam directly upon the goods while in the creasing means consisting of perforations in said table through which steam may pass communicating with a steam supply, and means of controlling said steam supply independ ent of the control of the steam in the steamjacket.

5. In combination in a creasing machine, a table provided with means of heating the same to apre-determined desired point.

means of controlling said heating means and automatically maintaining the same at said desired point, means of turning the fabric into crease attached to said table. means of steaming the fabric as desired while held by said creasing means.

6. A creasing machine comprising, a steam jacketed table an auxiliary steam passage within said jacket and communicating with orifices through said table a cloth clamping means to hold clot-h on to said table, and a creasing means operating upon the cloth so clamped.

7. A creasing machine comprising, steam jacketed table, an auxiliary steam passage within said jacket and communicating with orifices through said table said orifices being disposed and pointed to direct steam on to the edge of the cloth being creased.

8. A creasing machine comprising, a steam-jacketed table, an auxiliary steam passage communicating with orifices through said table. a cloth-clamping means to hold cloth on to said table, and a creasing means operating upon the cloth so clamped.

9. A creasing machine, comprising a steam-jacketed table, an auxiliary steam passage communicating with orifices through said table, said orifices being disposed and pointed to direct steam on to the edge of the cloth being creased.

10. In a creasing machine. a steamjacketed table, an auxiliary steam passage within said jacket communicating with a spray-nozzle for steaming goods being creased, and a cloth-creasing means secured to said table.
