and Batting Machines, of which the following is a specification.
The agitatingand batting machines of known construction show great defects as regards construction and shape of the agitating element so that in comparison to their eliiciency they are clumsy and heavy machines, demand a great expense of power and are expensive as regards putting up and at tendance. According to the invention the little requirement of power, the intimate and thorough mixing, the simultaneous treatment of the mass to be agitated and the uniform distribution of air bulbs in the mass are obtained by an improved construction of the agitating element which moves at a very short distance along the bottomand side walls of the agitating vessel and possesses working surfaces which gradually increase in outward direction. The agitating element is composed with this object in View of two narrow working surfaces of which the one at the rotation moves along a surface of rotation whichextends at a quite short distance from the bottom and side walls of the vessel,
the other working surface moving along a surface of rotation which gets larger from the bottom to the upper end of the vessel and is funnel-shaped. The two main working surfaces are further connected with one another by narrow arms. Owing to this arrangement the number of revolutions of the agitating element can be considerably lower (only about 200 revolutions per minute) than at present and the entire mass remains nevertheless within the range of the two working surfaces, and is permanently acted upon by these working surfaces. The narrow working surfaces of the agitating element which stand eccentrically to the axis of rotation of said element and the low number of revolutions permit of reducing the power required. The small electro-motor designed for driving the machine serves at the same time as support for the machine which is of little height, a lattice girder being fixed by screws on the motor which stands upon a socle, the two shafts of the agitating elements being mounted in the ends of said girder. The belt pulley of the motor drives by its belt, stretched by the spring-controlled guide pulleys and deflected by these pulleys at right angles directly the belt pulleyof one of the shafts, a second belt coupling the two shafts. The construction of the deflect- 111g pulleys as elastic stretching pulleys for the belt permits of regulating the number of revolutions by a more or less great stretching ofthe belt sothat this belt slips more or less. The agitating shafts are mounted in their bearings so that they can be freely shifted in upward direction, thebushes of the bearings having outer threads so that they may be adjusted in the lattice girder in order to accurately adjust the position of the agitating element. By a stop adapted to be released the bushes are prevented from rotating accidentally. 'The' rod or shaft of the agitating body is freely movable in the hollow axle of the corresponding belt pulley and it is coupled in its lowest position so that'it rotates with said axle; Afterthe agitating elements have been raised the vessels can be removed. The height of themachineis thus reduced. The variation of the eccentricity of the agitating element permits, in combination with the adjustable position as regards height, to adapt the agitating element to vessels of different size.
The cost of manufacturing is reduced by the movability of the hollow axlesof' the belt pulleys, any damaging of the machine by-incorrect adjustment of the agitating elements being prevented.
The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding that while on the drawings one embodiment of the invention is disclosed, the invention is not confined to any strict conformity with the showing of the drawings, but may be embodied in any manner which does not make a material departure from the salient features of the invention.
In the drawings:
Fig. 1 shows in side elevation artly in section the improved agitating and batting machine.
Fig. 2 is a plan view of the vessel with the agitating elements.
Fig. 3 shows on larger scale than Fig. 1'
the support for the deflecting pulleys.
Fig. 4 is a plan view of Fig. 3. e
The electro-motor 1 with the stepped grooved pulley 2 serves as socle for the lattice girder 3 at the ends of which the two bearing bushes 5, 5 having each a hand wheel 4 are screwed in vertically. Clamping screws 6, 6 of the lattice girder slit at these points serve to prevent the bearing bushes from rotating accidentally. The hollow axle 7 is driven from the electro-motor 1 by a cord 8 guided in the grooves of the belt pulley 2, of the deflecting pulleys 9, 9 (Fig. 4 and of the belt pulley 10. According to whether the cord8 is placed in the greater or shorter groove of the belt pulley 2 the number of revolutions of the shafts of the agitating element is altered, the required length of cord being equalized in both cases by placing the cordin the shorter or in the greater groove of the deflecting pulleys 9, 9. The bolt 11 (Figs. 3 and 41-). with cross arms 12, 12 which carry the stretching rollers 9, 9, has at its upper end a threaded extension on which a hand wheel 13 is screwed by means of which the rope tension is regulated by raising or lowering the bolt 11. On the lattice girder 3 a bow-shaped support 14 is fixed on the cross bar of which a spiral spring 15 rests which is wound around the threaded extension of bolt 11 and presses with its upper end against the hand wheel 13. The bolt 11 is prevented from rotation by means of a stud 16 engaging with a slot 17 of the bow-shaped support let.
The hollow axle 18 of the other agitating element, designed for lighter work is rotated by means of a cord or belt 19 placed around the grooved pulleys 10 and 20.
The flat agitating elements 21, 21 are eccentrically arranged with regard to their axes of rotation in order to reduce the power required and to exert an eccentrical action on the mass to be agitated. The shafts 22, 22 of the agitating elements 21, 21 are screwed into cross rods 23, 23 which have several threaded holes 24 so that the eccentricity of the agitating elements may be regulated in accordance with the size of the vessels. The shafts 22, 22 are screwed at the upper ends into shafts 25, 25 with heads 26, 26, said supporting shafts 25, 25 being adapted to be raised and lowered in the hollow axles 7, 18 respectively. In the lowest position of the shafts 25, 25 coupling pins 27, 27 of these shafts engage with corresponding borings 28, 28 of the grooved pulleys 10, 20 respectively so that the shafts rotate with these pulleys.
This arrangement permits of pulling the agitating elements up'to remove the vessels 29, 29 and to prevent the soiling of the shafts 22, 22 by lubricating oil which would happen if the shafts 22, 22 were directly screwed i into the axles 7, 18 respectively.
hen the agitating elements 2i have to be cleaned the shafts 22, 22 are unscrewed from shafts 25, The electro-uiotor l and the two agitating vessels 29, 29 rest upon the base plate 30 which stands upon feet 31. 31 so that the vessels 29, 29 can be heated from below.
