Specification of Letters Patent.
'Patented Nov. 20,1906.
Applicatiml filed August 11,1902. Serial No. 119,266.
To all whom it may concern.-
Be it known that I, JUSTIN KAY ToLEs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Making Plaster Paris Bandages, of which the following is a specification.
This invention relates to novel improvements in machines for making plaster-paris bandages; and its object is to provide a simple and inexpensive machine which can be easily operated for making plaster-paris and other band ages of a like character which involveapplying pulverulent plaster-paris or similar product on a web.
Another object of the invention is to thoroughly incorporate the plaster material in the fabric backing or foundation and spread the material in a smooth and even layer to provide a bandage of uniform character throughout its length, and a further object of the invention is to provide for winding the bandage in rolls of predetermined length and automatically stop the machine when the roll has been completely wound.
Another important object of the invention is to produce a roll which will at once become thoroughly and completely saturated when the roll is submerged in water by winding the bandage comparatively loosely at the center and comparatively tightly at the outer part of the roll.
Another important object of the invention is to provide for depositing powdered alum on the web to commingle with the plasterparis to absorb any moisture which. may be present, and thereby keep the plaster in a perfectly dry condition for an indefinite period and ready for instant use; and still another important object of'the invention isto provide for depositing powdered alum on the web to commingle with the plaster-pa'ris to' hasten the set and increase the tensive strength of the bandage when applied.
With these and other ends in view I have illustrated one manner in which the machine may be embodied in the accompanying drawings, referring to which Figure 1 is a front view of a machine embodying my invention. Fig. 2 is a side elevation of the machine, parts of the frame being broken away to show the operating mechanism. Fig. 3 is a vertical sectional view.
Fig. 4 is a sectional view on the line 4 4 of Fig. 3. Fig. 5 is a sectional view on the line 5 5 of Fig. 3. Fig. 6 is a sectional view on the line 6 6 of Fig. 4.
Referring to the drawings, in which like numerals of reference indicate corresponding parts in the several figures; 10 designates the main drive-shaft, which is provided with a loose belt-pulley 11 and is journaled in bearings in a frame of suitable construction, which is designated generally by 12. The belt-pulley is made tight with the main shaft by means of a clutch of suitable construction operated by a lever 13, Fig. 2, which is conveniently arranged at the front of the machine and works on a guide 60. ings I have shown a'movable disk 14, keyed to the shaft 10 and provided with studs 15, adapted to enter holes in the disk 16, rigid with the pulley 11, so that when the lever is thrown the disk 14 will be carried forward and the studs thereon will enter the holes in the disk 16 to lock together the pulley, the sliding disk, and the shaft, Fig. 5.
A drum 17 is mounted on a shaft 18, journaled in the frame, and this drum is operated by means of an internal gear 19, which meshes with a pinion 20 on the main shaft,
Fig. 5. The drum is provided with a covering 21, of carpet or other suitable material, which will serve to hold the web 22 and make the drum feed the web forward beneath the spout 23 of the hopper 24. The web is preferably wound on spools 25 and mounted on a shaft 26, journaled in bearings in the brackets 27 on the frame, and the web is carried from the spool, preferably over one or more tension-rollers, and over the feed-drum to the winding-spindle, as indicated in Fig. 3.
The hopper and its spout are of any suitable construction, and an agitator 28 is preferably arranged in the hopper and operated a 'belt 29, running on the pulley30 on the agitator-shaft 31 and on the pulley 32' on the dri1m-shaft 18. The spout is provided with a "a glass front 33 in one part thereof, so that In the draw- ICO the operator can observe when the supply of material is becoming exhausted. The hop per-spout has its discharge en'd shaped 'to conform substantially to the periphery of the drum, and it discharges the material on the web while the latter is being carried by the drum across the discharge-opening. A gate 34 is pivotally mounted-on a bracket-arn. 35,
fastened to the spout, and this gate is normally held by aspring 36 to bear upon the 1 web at the point where it emerges from below the discharge-opening in the spout. This gate operates not only as a tension device for the web, but also as a scraper to remove surplus material deposited on the web and to spread the material evenly over the web.
For the purpose of cleaning the covering on the drum and to prevent it becoming clogged with the plaster material I provide a revolving brush 37, Fig. 5, which is carried by a shaft 38 and operated from the drumshaft by means of the gears 39 40 and the intermediate idle gear 41, so that the brush will turn in the same direction as the drum turns, but inan opposite direction at their meeting edges, and keep the, surface of the covering of the drum free from plaster.
The bandage is bound in rolls on a spindle 42, to which it is clamped by means of a spring-clamp 43. In fastening the web to the spindle the clamp 43, Fig. 6, is arranged in the socket 44 of the movable support-45, and this support is caused to carry the clamp upward with the web thereon and fasten it securely to the spindle. A toggle 46 is connected to each end of the support and to the frame at 47, and cords 48 are fastened to the toggle and run over the pulleys 49 and are connected to a pedal-lever 50. The weight of the support is suflicient to carry it to its normal lowered position, or a spring may be connected with the pedal-lever for this purpose, and it will be readily observedthat when the pedal-lever is depressed the cords will be drawn to operate the toggles and throw the support upward and force the clamp upon the spindle with the web tightly held between them.
The spindle is journaled in suitable bearings in the frame and is driven by means of a pinion 51, which meshes with an idle pinion 52,'Fig. 4, and this latter pinion is operated by means of a sprocket-chain 53, traveling on a sprocket-wheel 54 on the main shaft and on a sprocket-wheel 55, connected with the pinion 52. The spindle is adapted to be disconnected from the bandagerolls and the clamp by simply withdrawing it at the side of the machine, the clamp bearing at that time against the socket-plate 56 in the frame, and in order to connect the spindle with the driving-pinion 51 I provide a clutch device of suitable construction, which in the drawings I have shown to consist of a friction-disk 57, rigid with the spindle, and a corresponding disk 58, rigid with the pinion 51,. these disks being each provided with a fiber facing of suitable material to provide sufficient frictional engagement surfaces.
In order to regulate the speed at which the spindle revolves ,and thereby control the winding of the bandages, I provide a handlever 59, which is bifurcated or otherwise constructed in a suitable manner .to engage the boss 62 on the disk 57, so that this disk may be clamped tightly with the disk 58 to revolve coincidently therewith, or the pressure may be reduced by operating the handlever to decrease the friction and permit the spindle to travel at a lower rate of speed than the driving-pinion. I prefer to wind the bandage-rolls loosely at the center and comparatively tightly at the outer part thereof, and it will be readily understood that this can be easily accomplished by manipulating the hand-lever, and thereby regulating the speed of travel of the spindle. This hand lever is normally under tension of a spring 63, which tends to keep the clutch open.
I provide a knife 64 for severing the web after the roll has been wound, and this knife is pivoted to the frame at 65 and is operated by means of a lever 66, connected with the heel of the knife by a link 67, Fig. 1.
For the purpose of regulating the length of bandage in a roll I provide a disk 68 011 the brush-shaft 38 and arranged to engage the lower end of the lever 69, to the upper end of which the hand-lever 13 is connected and by means of which the clutch on the main shaft is operated. The disk is provided with a slot 70, in which the lower end of the lever 69 is adapted to seat itself after a bandage of the proper length has been wound in a roll on the spindle. If it is desired to wind bandages of a length of five yards, the parts may be constructed and proportioned so that the brush-shaft will revolve once to five revolutions of the drum-shaft, or at least until a roll of the required length has been wound on the spindle. In its normal position the lower end of the lever 69 is seated in the slot 70, as shown in Fig. 5, and when the hand-lever is operated to throw the clutch and start the machine the lower end of the lever 69 will be carried out of the slot and will ride against the peripheral edge of the disk, being held in this position by means of the spring 71, Fig. 2, until the disk has made a complete revolution, when the lower end of the lever will again be carried bythe spring into the slot 70 and the clutch opened and the machine stopped.
With a machine constructed in accordance with my invention, ashereinbefore described, I am able to apply the plaster to the web evenly and expeditiously and wind a number of rolls of the same or different widths simultaneously, and the bandages will all be of uniform length. The web is held at tension in passing around the drum, and as it is generally a loosely-woven fabric the fiber of the carpet will operate to some extent to spread the fibers of the web, so that the plaster will penetrate the web and cling thereto. The plaster is spread upon the web evenly and smoothly by means of the gate 34, and this gate also holds the web at tension between IOK ITO
the discharge-spout of the hopper and the spindle, so that the web will not vibrate and. loosen or throw off the plaster. I'provide a chute 72, through which the plaster that is brushed off of the drum, as well as any that may come from the web,"may fall into a really to increase the speed of the spindle, and
thereby cause the web to be wound more tightly as the roll gets larger.
In connection with the machine as heretofore described I may use the following mechanism for depositing powdered alum on the web before the plaster is applied thereto. This mechanism comprises a hopper 74, Fig. 3, between the feed-drum and the supplyspool, and the web is carried from the supplyspool around a roller7 5 at the lower 'dis-' charge end of the hopper and around a roller 76, across or partly'across the top of the hopper, and around a roller 77, from whence it passes to the drum and preferably against a tension-roller 78. The roller operates as a feed-roller to'carry the powdered alum from g the hopper to the web, and in order to regulate the supply of alum thus carried by the feed-roll I provide a scraper 79, which is fastened to the hopper and operates, in conjunction with the feed-roll, to permit only a predetermined quantity of the alum to be applied to the web. As a further precaution against the web carrying off too much alum, I preferably cause the web to travel across the open top of the hopper in the manner previously described and then provide means for vibrating the web between the rollers 76 and 77 to loosen and discharge any surplus alum that may be carried thereby. This vibrator may be constructed in many different shapes; but in the drawings I have shown a simple form comprising a shaft 80', carrying flexible arms 81, made of leather or other suitable material and arranged to strike the web, the. shaft being driven by a belt 82, traveling on the pulley 83, and a pulley 84 on the brush-shaft, Fig. 5; The alum which is thus applied in small quantity'to the web before the plaster is applied will absorb all moisture in the fabric and whatever moisture may be taken up by the fabric from the atmosphere, and thus the plaster is entirely freed from moisture as it is made, and it will be preserved indefinitely, so that it will always be in perfect condition for immediate use. Of course the alum-applying mechanism may be dispensed with, if desired; but I prefer to use it in connection with the other parts of the machine in the manner shown and described.
I have described the machine as utilized for making plaster-paris bandages; but I do not limit myself to this particular use, as it may be adapted and used for other purposes and with equally satisfactory results; nor do I limit myself to the particular construction 'and arrangement of parts shown and described, as these maybe varied and changed to suit different conditions without departing from the spirit or sacrificing the advantages of the invention. 7
