Be it known that I, VVILI-IELM ALBERT STELLMAGHER, a citizen of the Republic of Switzerland, and residing at Arbon, Switzerland, have invented certain new and useful Improvements in Embroidering-Ma chines, of which the following isa specification.
The present invention has reference to certain new and useful improvements in'embroidering machines, and relates more specifically to improved means for suspending the work-frame, on which the ground work is stretched; and the particular object of the invention is to sosuspend this frame that an easy, even displacement of theframe is assured in all positions and the operating height and width of the machinefis not encroached upon in any way. M
The nature of my invention will best be understood when described in connection with the accompanying drawings, in which Figure 1 represents a side elevation of a preferred form of construction;'Fig. 2 is a front elevation thereof; Fig. 3 shows a front elevation of a constructional modification; Fig. 4 shows a side view of a detail of Fig. 3, and Fig. 5 illustratesa sideview of a modified detail.
In these drawings 1 denotesthe main uprights of the machine frame, which are connected by cross-members 2. The embroidery-frame 3 rests by means of rolltrs 4: on horizontally disposed rails 5, which in turn are vertically displaceable in guide-supports 6.
In the construction, illustrated in Figs. 1 and 2, horses 7 for journaling pulleys are provided on the main uprights 1, and flexible draft-members, such as ropes, fiat metal bands or the like, run over these pulleys and are respectively secured to the horizontal rails 5 and to the drums 10, which latter are fixed on the shaft 11. This shaft extends clear across the machine and is journaled in brackets 12' on the uprights 1 and in bearings 13 on the upper cross member 2. To the shaft 11 is secured near one of the brackets 12 a curve or cam 14 to which in turn is secured the upper end of a draft-member 15. Its lower end is secured to the cam 16 which is fixed on the shaft 19. The latter is journaled in bearings 17 and 18 which are respectively secured to the machine upright and to the lower cross-member. To the cam Specification of Letters Patent.
Patented Nov. 1c, 1915.
16 is secured the one end of the torsional spring 20, wound around the shaft 19 and whose other end is secured to a worm wheel 21. This latter rides loosely on the shaft 19 and meshes with an incasedworm, as at 22, which may be operated by rotating its square-ended shaft 23 (Fig. 1).
The two cams, interconnected by the flexible member 15, together with the helical spring 20 form the counterbalancing device for the embroideryframe, inasmuch as on displacement of the frame the lever arms of the cams vary, in keeping with the increase or decrease of the tension of the spring 20, in such manner that the compensation of the forces for all positions of the work-frame is assured.
By transmitting the movement to the work-frame by means of'the shaft 11, the frame, no matterhowwide, is so supported that its up and, down movements will ensue absolutely evenly.
In the modified form of construction, shown in Figs. 3 and 4, there is secured near each end of the shaft 11 a caml, each of which is connected to a correspondinglower cam 16. Correspondingly there are provided two shafts 19, two torsional springs 20 and two jworm gears. Between the uprightsl there are secured to the cross-members 2 brackets 24 in which are provided bearings 25 for the shaft 11, bearings '26 for pulleys 8, and supports 6 for the horizontal guiderails 5. Flexible draft-members 9 are secured respectively to the guide-rails 5 and to the drums 10 fixed on shaft 11, and run over the pulleys 8, as clearly shown in Fig. 4. In this construction, then, the counterbalancing device comprises two pairs of cams, the two cams of each set being interconnected by a flexible member and influenced by a torsional spring, and deformation of the work-frame by sagging is eifectivelv prevented for the reason that the frame is sus pended from a plurality of intermediate flexible members, one near each bracket 24:-
Instead of using a single long shaft 11, it is obvious that also several short shafts may be used, in which instance the several shafts 19 would have to be united into a single shaft extending clear across the machine.
The torsional spring 20 can also be replaced by a draw-spring 27, as shown in Fig. 5, whose one end is suitably secured tothe machine frame, and whose other end is secured a 01 by the interposed flexible member 2 8.
By connecting counterbalancingrr device and work-frame by a shaft andaflexiblel.
draft-members, the device can be so mountedon the machine that the operating height and width of the latter is in no wise inter- "frame of an embroidering-machine and the iwork' frame thereof; of shaftsmon'nted on fered with, with the result that the space" available for setting-up the machine can be utilized to the fullest extent.
What I claim is:
1. The combination i with the 'supporting thesu'pporting frame, pulleys fmo'unted on the supporting frame, drums on one of the shafts, flexible "connections from said drums flexible suspending "and passing over said pulleys to'the work frame, oppositely directed cams on the shafts, flexible members connecting the cams and adjustable counterbalancing mechanism cooperating with said cams.
2. 1n an embroidering machine,-the combination' with the machine frame and the Work frame thereof; of drums and guide pulleys mounted on the machine frame, means guided bysaid pulleys and connecting the drums and work frame;- oppositely directed cams haying a I flexible connection between them, and counterbalancing means for the work framecon'b" prising resilient me ns acting on one ofthe cams and means for altering the tension 'on i said resilientineans.
3. In an embroldering machine, the combination with the machine frame and the work frame thereof; of drums and guide pulleys mounted on the machine frame,
Copies of this patent may be obtained for flexible suspending means guided by said pu leys an c n c ing theidr sw n ork frame, oppositely directed cams connected with the'drums, flexible connections between V the cams, suspending means connected to the frame at points intermediate its ends, and
