Description
April 5, 1955 F. ARBONA NAvARRo SPINDLE FOR SPINNING AND TWISTINGMACHINES Filed May 27, 1952 INVENTOR. Fmwcrsco Anson/A NAVARRO BY United States Patent `O SPINDLE FOR SPINNING AND TWISTING MACHINES Francisco Arbona Navarro, Barcelona, Spain Application May 27, 1952, Serial No. 290,307
Claims priority, application Spain May 30, 1951 2 Claims. (Cl. 57134) This invention relates to improvements in spindles for spinning and twisting machines.
Spindles for spinning or twisting machines are known comprising a hollow support shaft into the interior of which the bottom end of the spindle proper is introduced. The end of the spindle is supported at its lower end on the edge of the support shaft and is g'uided by a pin which is introduced into the interior of said shaft.
In order to prevent the spindle from leaving the support when the bobbin is removed, a bobbin rail is provided which holds the spindle in position without depriving it of its normal function.
Spindles of the foregoing kind suffer from the disadvantage that there is a considerable amount of friction between the parts which must accordingly be lubricated periodically to reduce wear and to ensure good operation.
An object of the present invention is to provide a spindle of the foregoing kind in which wear due to friction of the parts is substantially reduced.
A further object of the invention is to obviate the necessity for provision of the bobbin rail and thus to remove another point at which wear occurs.
The invention has for a further object the provision of continuous lubrication of the spindle'par'ts and thus to ensure smooth running of the device.
With the foregoing and other objects in view the present invention consists in a spindle for spinning and twisting machines of the kind comprising a spindle proper, including a bobbin receiving portion and an integral spindle mounting portion constituted by a rod, and a hollow support shaft, adapted to be mounted in said machine, in the interior of which said rod is rotatably mounted, characterised by a tube screwed into said support shaft, said spindle mounting rod being housed in said tube, a footf' step bearing point on the bottom end of said rod, and a bearing rockably mounted in said tube for receiving said point and supporting said rod.
In order that the invention may be more readily understood, reference is made to the accompanying drawings, which illustrate diagrammatically and by way of example two embodiments of spindle in accordance therewith, and in which:
Fig. 1 is a longitudinal section of the spindle;
Fig. 2 is a similar view of the upper portion of the device showing the unlocking of the spindle from the support tube; and
Fig. 3 is a view partly in section of the lower part of another embodiment having a reservoir for lubricant.
The spindle constructed according to the invention is constituted by a support shaft 1, inside which is housed the bottom end of the spindle proper. The latter is con stituted by a tube 2 which is screwed into the support shaft; inside said tube is housed the bottom rod 3 of the spindle, which is integral with the rod 4 on which the bobbin is placed.
The rod 4, or bobbin carrier, terminates at its lower end in the form of a sleeve, which externally is shaped as a pulley 5 through the groove around which passes a driving cord or belt (not shown) for rotating the spindle.
The spindle proper is supported by a footstep bearing point 6 formed on the end of the rod 3, engaging in a cup bearing 7 rockably mounted in the bottom end of the tube 2. By virtue of this construction the wear on the point 6 is reduced to a minimum since any eccen- Patented Apr. 5, 1955 tricity in the running of the spindle is taken up by the rocking of the bearing.
The tube 2 and the cup bearing 7 have grooves 8 and apertures 9 respectively, to permit ya lubricating oil to circulate freely in the interior of these parts.
The bottom rod 3 of the spindle is tapered to permit the oil entering through the grooves and apertures to rise with the rotary movement of the spindle towards the upper end of the tube 2, which has its interior edge 0 10 bevelled.
Due to this construction, the spindle is continuously lubricated because on rotation of the spindle the oil contained in the bottom of the support shaft 1 rises to the bevelled edge 10 of the tube 2, so that a ring of cooling oil is formed. When rotation of the spindle caes, the oil drops back to the bottom of the support s a t.
In this type of spindle, the oil is introduced through the end of the tube 2, after rst removing the spindle, without it being necessary to renew the oil until` after at least six months continuous use.
In order to prevent the spindle from leaving the spindle carrier or support shaft a plurality of steel balls 11, which are housed in apertures provided in the sleeve of the spindle, after the manner of bearing balls, are thrust towards the interior of the sleeve by means of a retaining ring 12, and are positioned between the apertures and a small annular groove 13 provided in the upper end of the tube 2 (Figure 1).
In order to remove the spindle from the spindle carrier, it is suicient to raise the retaining ring to allow the balls to move outwardly and thus tdisengage the groove 13 and permit the withdrawal of the` spindle (Figure 2). The movement of the retaining ring 12 is so arranged that the lower edge of the ring prevents the balls from completely passing out of the corresponding apertures when the spindle is removed. The balls are similarly prevented from falling out inwardly by making the inner end of the apertures slightly smaller in diameter than the maximum diameter of the balls.
The embodiment shown in Fig.. 3, is similar to the above-described embodiment but with an interchangeable oil reservoir 14 secured to the lower end of the support shaft or spindle carrier 1. The reservoir 14 detachably mounted with a system of balls similar to that employed for preventing the spindle from becoming detached from the spindle carrier and, to this end, the nut 15 used to secure the spindle carrier to the spinning machine is provided with a tubular extension 1|6 having an annular groove into which balls 17 engage when subjected to pressure by a retaining ring 18.
In this way, when it is necessary to change the spindle lubricating oil, it will be suicient simply to move the retaining ring 18 upwards in order 'to remove the reservoir.
I claim:
1. A spindle for spinning and twisting machines of the kind comprising a spindle proper, including a bobbin receiving portion and an integral spindle mounting portion constituted by a rod, and a hollow support shaft, adapted to be mounted in said machine, in the interior of which said rod is rotatably mounted, characterized by a tube screwed into said support shaft, said spindle mounting rod being housed in said tube, a footstep bearing point on the bottom end of said rod, a bearing rockably mounted in said tube for receiving said point and supporting said rod, means for locking said rod in said tube comprising a sleeve on said s pindle-receiving por tion spaced apart radially from said rod, a plurality of radially extending apertures in said sleeve, a ball in each of said apertures, an annular groove in the upper end of said tube and an axially slidable retaining ring on said sleeve adapted to close and uncover the outer ends of said apertures, the arrangement being such thatportion constituted by a rod, and a hollow support shaft, adapted to be mounted in Vsaid machine, in the interior` of which said rod is rotatably mounted, characterized by a tube screwed into sva'id support shaft, said spindle mounting rod being housed in said tube, a footstep bearing point on the bottom end of said rod, a bearing rockably mounted in said tube for receiving said point and supporting said rod, an oil reservoir detachably secured at the lower end of said tube by locking means comprising a plurality of radially extending apertures in said reservoir, a ball in each of said apertures, a tubular extension on the spindle fixing nut, an annular groove in said extension, and an axially slidable retaining ring on said r S.'-..f.v0ir.f0t @viering andwlmsfvering the outerend 0f each of said apertures, the ,arrangement being such that with said ring closing said apertures, said balls are moved radially inwards to enter said groove and to lock said reservoir relatively to said extension.
