MOTOR ATTACHMENT FOR SEWING OR OTHER MACHINES.
Specification of Letters Patent.
Patented Aug. 17, 1920.
Application filed January 21, 1919. Serial No. 272,257.
To all whom it may concern:
Be it known that we, EMANUEL lVAcMAN and HARRY BRUSSELL, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Motor Attachment for Sewing or other Machines, of which the following is a specification.
ur invention consists of means for operatlng a machine or a gang of machines, such as a sewing machine or sewing machines from a main power shaft which may be common to the gangs of such machines, said means admitting also of running said machines independent of each other without either machine controlling the other machines, said means also embodying stopping mechanism for each machine independent of the other machines, as will be hereinafter set forth.
The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.
Figure 1 represents a side elevation of an attachment for operating a gang of sewing or other machines embodying our invention.
Fig. 2 represents a vertical section thereof of a portion on an enlarged scale.
Fig. 3 represents a vertical section of a portion on line 33 Fig. 2.
Fig. 4 represents a vertical section of a portion on line 44: Fig. 2.
Similar numerals of reference indicate corresponding parts in the figures.
Referring to the drawings- 1 designates the top of a table or stand on which are supported a gang of machines, in the present case, sewing machines, each of which is adapted to be operated orrun independently, of each other. Mounted on the legs or standards 2 of the frame of the table below the top 1 thereof, is the power or main driving shaft 3 which is adapted to be operated by the pulley members 4:, or other suitable means on said shaft.
On said shaft 3 below each machine is fitted a clutch 5 which is composed of the fixed member 6 which is secured to the shaft 3 by the bolt 7 or other means, whereby said member is rotatable with said shaft and consequently receives power therefrom.
The other member 8 of said clutch com prising the slidable member of the latter has a hub 9 which is fitted on and secured to a tubular sleeve 10 by means of the bolt 11 or other means, herebywhen said member receives rotation from the member as hereinafter described, the rotation is communicated to said sleeve, it being noticed that said sleeve surrounds the adjacent portion of the shaft 3, one end of the same being sustained on the hub 12 of the clutch member 6, which hub is fitted on the shaft 3, as most plainly shown in Fig. 2. The other end of said sleeve is fitted on the plug or bushing 13 which receives the adjacent portion of the shaft 3 and is secured thereto bythe bolt 14 or other suitable means.
On the sleeve 10 adjacent to said bushing is fitted the main driving pulley 15 which is secured thereto by the bolts 16 on the divided hub 17 of said pulley 15. Passing around said pulley is the endless belt or band 18 which also passes around the driving pulley 19 of the machine on the table 1, whereby the machine may be operated as will be hereinafter further described.
On the hub 9 of the clutch member 6 is the collar 20 which encircles said hub and is engaged by the shipper 21 which freely occupies a groove in the exterior of said hub, the upper end of said shipper being connected with the wing 22, one of the many wings of the lever 23 which is pivotally mounted as at 24 on the bracket 25 which depends from and is secured to the underside of the table 1 below said machine.
The wing 26 of said lever has attached to it the upper end of the connecting rod 26 of the foot operated treadle 27, the latter being mounted on the floor of the working apartment.
The end of the wing 28 of the lever 23 has seated on it the spring or resilient device 29 whose upper end is seated on the underside of the branch 30 of the bracket 25, said spring being adapted to restore the lever 23 and connected parts to normal position, as will be further explained.
On the outer end of the wing 31 of the lever 23 is the buffer or cushion 32 which is adjacent to the side of the main driving pulley 15. Adjacent to the opposite side of the latter is the buffer or cushion 33 which is supported on the bracket 34 which depends from and is secured to the underside of the table 1.
It will be understood that each. machine 35 which in the present case is a sewing machine as has been stated may receive power independent of the other machines and each machine may be rendered inoperative without disturbing the other machines, each machine being primarily controlled by an operator? thereof through the respective treadle, it being seenthat when a machine is to be run, the operator thereof depresses the treadle thereof, the shaft 3 continuously rotating and with it the members 6 of all of the clutches.
The rod 26 operates the lever 23 whereby the shipper 21 moves the collar 21 and advances the member 8 of a clutch to the member 6, thereof, thus closing the clutch. In this movement of the clutch member 8, the sleeve 10 receives a slight sliding motion therefrom to the left and so toward the clutch member 6. Now as the clutch is closed, said sleeve is rotated by the same and so the pulley 15 is rotated when owing to the belt or band 18 the driving pulley 19 of the machine is rotated by the same, thus operating said machine. As the wing 31 of the lever 23 is lowered by the rod 26 the cushion 32 moves sufficiently from the pulley 15 so as to have no friction therewith.
When the operation of the machine is to cease, the operator having controlled the treadle now removes his foot therefrom, when the spring 29 previously compressed is free to expand and so operates the lever 23 as to restore it to its normal position, the shipper then withdrawing the clutch member 8 from the clutch member 6, thus opening the clutch when rotation of said member 8 is stopped and with it the sleeve 10, the main pulley 15, and the driving pulley 19 of the machine, the operation of the latter thus ending.
The ascent of the wing 31 of the lever 23 moves the buffer 32 against the main pulley 15, the latter being placed innormal position'by the slight sliding action of the sleeve 10, in the present-case to the right, said buffer 38 then being pressed as a brake against said pulley, the latter being also pressed on its opposite side against the buffer 33 as an additional brake, thus holding said pulley against rotation and so quickly preventing operation of the driving pulley 15, and consequently of the machine, but-the other machines may receive power so as to be run and operated without regard to or interference by the operation of a machine above described, and said other machines may also be stopped as desired, but the power ormain driving shaft 3 continues its rotation so that any machine or all machines may-be run by the different operators independently of each other.
Our device admits of raising the main power shaft and the appurtenances thereon underside of the table 1 so as to be removed from the operators knees, and the portions of the garments under the table, allowing also the greatest freedom of his feet and body below the table, and the operation of the treadle Without said feet and body contacting with the power shaft and adjacent mechanism.
Having thus described our invention what we'claim as new and desire tosecure by Letters Patent, is
1. In an operating attachment-for sewing or other machines, a main power shaft, a clutch comprising members one-fixed and the other slidable with reference to said shaft, a main driving member spaced from said clutch, a pivoted member having wings for frictional cooperation with said driving member and the slidablemember of the clutch, and a buffer for cooperation with the driving member in opposition to the wing that cooperates therewith.
2.
