sEwlNG MACl-ilNE SUPPORT.

Patented June 8, 1920.

Application filed October 13, 1919. Serial No. 330,417.

To all whom it may concern.- I

Be it known that I, JOHN A; MoCRAoKnN, a citizen of the United States, and a resident of Evenell, Rahway, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Sewing- Machine Supports, of which the following is a specification.

This invention relates to an improved support for sewing machines, and is of the type that is adapted for use in handkerchief mills and similar establishments where more than one machine is handled by a single operator. 7 v

I am aware that tables have been made in which one sewing machine is arranged above another, which arrangement has been found to result in reduced output on account of the operator being under the necessity of straightening up and then bending over so frequently as to become exhausted.

I am also aware that machines have been arranged on a tablewith their sewing ends spaced apart the width of the goods to be seamed or sewed, but this arrangement takes up a great deal of room and requires nicety of adjustment. and synchronizing.

The present invention is adapted to mini- 7 mize thespace necessary and at the same time to permit a single operator to attend to two machines and keep them continuously supplied with articles, such as handkerchiefs to be hemstitched.- I

For the purpose of clearly describing this invention it will be referred to as used in hemstitching handkerchiefs, so as to clearly indicate how it is an advantageous installation.

The invention further consists in the disposition of the sewing machines made possible by the'construction of the table, and also in the arrangement of details in the construction. all of which will be more fully described hereinafter and finally embodied in the claims. V

The invention is illustrated in the accompanying drawings. in which Figure 1 is a top view of a pair of tables made according to my present invention, with two sewing machines illustrated in place on one of the tables. Fig. 2 is an end view ofthe construction shownin Fig. 1, all the sewing machines being illustrated in position. Fig.

3 is a front viewof the construction shown in Fig. 1.,with the sewing machines on the rear table being shown in dotted outline.

also showing the hemmer and an attachment to the hemmer which permits of the feeding of the edge of material to be hemstitched, to the sewing machine.

It will be evident that one support for two machines can be utilized, but for the purpose of illustrating possibilities of the invention I have shown two of such tables arranged for the complete support, in the illustration these tables being shown as being identical, but, of course, it will be evident that slight changes are possible.

The support consists of a front table 10, which has on one end a side table 11 which projects at an angle from the front of the front table 10 and is preferably arranged at a right angle thereto. When more than one of these table portions or supports are used, they are placed back to back and a trough 12 is arranged between them, the whole be ing supported on standards 13 which are preferably provided with top braces or trusses 14. adjustable on the standards 13 and secured in position by suitable fastening means. such as the bolt 15.

The machines are driven by suitable mechanism or connection from a main shaft 16, preferably supported in suitable bearings 17 on the standards 13. On the front table 10 is a sewing machine 18, and on the side table 11 is another sewing machine 19, the machine 18 being driven by a belt 20 running from the usual pulley on the machine to a pulley 21 on the shaft 16, and the machine 19, which is at right angles to the machine 18, is driven by a belt 22 which passes from the pulley of the sewing machine under the idlers 23 and around the pulley 24 on the shaft 16.

Each machine is provided with the usual clutch mechanism, which is not illustrated. in detail in this application, these clutch mechanisms being well known in the art, the machines being provided with arms 25 which are provided on the end with an extension 26 having a bar 27 which is actuated by a spring 27 a to normally hold the clutch open or inoperative.

The machines 18 and 19 are provided with starting and stopping mechanisms convenient of access and positive in their operations,lthe machine 19 being provided with a device comprising a rocking bar 28 which has one end 29 to engage the bar 27, the

other end being rocked by a cam-shaped ex which has a nose 35 and a handle 36, the

handle 36, when turned, causing the no se 35 to engage the standard33 and pull the bar 32 so that the extension 26 and the arm 25 are swung t'o'cause the clutch 37 of the machine to be thrown into clutching position and the machine operates. The disposition of this starting and stopping mechanism is such as to be within reach of the operator, who is situated approximately. at the position illustrated by the seat 38 in Fig. 1.

The sewing or needle end of the machine 18 projects toward the machine 19, and the needle end of the machine 19 projects toward the front end of the table 11. To illustrate the convenience of the arrangement set forth in this application I will describe the device as used-in the hemstitching of handkerchiefs. The operator, situated at 38, feeds the goods to the sewing end of the machine 19, and, in the. case of handkerchiefs, the goods is fed through until the required distance on one edge has been hemmed, and the piece is then hemmed on a second edge in the machine 18, on, its third edge on the machine 19 and onits fourth edge back on the machine 18. An operator proficient in the operation of these machines has both machines in operation almost continuously, since the goods only has to be started in the machine, and while one machine is hemming the edge of a handkerchief the other machine is delivering one and being supplied with another. This alternation of feeding from one machine to the other permits of a large output by a single operator without undue exertion.

Furthermore, there is no unnecessary reaching for inaccessible elements thatrequire operation, and I have found that with this table installed alongside of the prior arrangements of machines, this is not only the most comfortable for the operator, but it delivers a much larger output. V

I F our-sided articles are usually started in the machine 19 sothat the final operation is V on the machine 18 and the goods pass into the trough 12, from which theyare removed atintervals, 7

When the machlnes are used for hem against the under face of the feeding plate 413 of the hemmer, so that once the goods are inserted in the hemmer this plate holds the goods up and causesit to be properly and evenly'fed to the hemmer.

To provide for the proper .tension, a tablet 44 is preferably placed on the front of each table and opposite the sewing end thereof, this being shown in connection with the machine 18in Fig. 1, the tablet 44 being inclined so as to more properly support the goods and also to cause a bending of the spring 40, which gives the end 4:2 Of the spring 41 the required tension. V

When two table portions are used, as shown in Figs. 1 and 2, the standards 13 with theiradjnstable tops or trusses 14 are supplemented by adjustable supports forthe outer ends of the tables 11, which supports comprise rods 45 on whiQh areadjustably arranged the sleeves 46 fastened by the screws 47 and havingthe arms 48 which support the outer ends of the tables 11. At one end of each set of tables I prefer to put a projecting part 19 which. spacesthe end of the table 11 from the next adjacent table 10 and insures the space 50 being left, so that, if desired, goods of considerable length being passed throughthe machine 19 canbe passed downover the edge of the table 11.

end projecting toward theend of said table, and the needle end of the other'projecting toward the first machine. i 1

3. A sewing mac hi ne;suppor t comprising a front ;table, a side'table at an angletothe front table,lthetables being at substantially the same level, and a. sewingwmachine on each table, whereby an operator at theangle of the tables can feed fabric to machines. I

4. A sewing machine support comprising a front table, a side tableproj ecting-at an angle from "the front {of the front table, sewing machines on both tablesgand a second front table and side table, sewing machines on both said second tables, the two r tables wea d. bi skt ack- '5. A sewingmachine support comprising tables placed back to back, and. a projecting table onflthe front of each' one, said project:

ing tables being on opposite ends, all said tables being equipped to support sewing machines.

6. A sewing machine support comprising tables placed back to back, a projecting table on the front of each one, said projecting tables being on opposite ends, and a trough arranged between the main tables, the main tables and projecting tables each being equipped to support a sewing machine.

7. A sewing machine support comprising tables placed back to back, a projecting table on the front of each one, said projecting tables being on opposite ends, a shaft supported longitudinally under said tables, sewing machines on the main tables and the projecting tables, and drivin means connecting the shaft and the sewing machines.

In testimony that I claim the foregoing, I have hereto set my hand, this 10th day of October, 1919.
