Description
' Feb. 13, 1934. M, STUHLER AGITATING MACHINE Filed Aug. 4. 15532 Witnesses;
Patented Feb. 13, 1934 UNITED STATES PATENT OFFICE andin Germany August 18, 1931 3 Claims. '(01. 259-91) I have filed an application in Germany on the 18 August 1931.
This invention refers to an agitating machine especially for-the production of concrete bodies 5 in moulds by the agitating-plate which carries the moulds and vibrates in a vertical direction. In the well known agitating-machines of this kind the heavy agitating-plate is set in motion by a crank gear; when vibrating in a vertical l0 direction, it knocks against the falling moulding-' box, and keeps throwing it up. As this heavy agitating-plate when in the upper dead centre position of the crank pinviolently .tries to continue the upward movement, these machines 16 must be strongly tied in firm foundation. Al-
though it is impossible now for themachine to tear itself away from the ground, the shock which is imparted to the surroundings cannot be entirely avoided. Owing to this disadvantage 20 the machine cannot be erected everywhere.
The invention has the purpose, to stop the disturbance caused by the vibrating masses, and to enable the machine to keep perfectly still, even under the heaviest weight of the agitating-plate and highest number of vibrations.
In order to obtain this end, the agitating machine has, through this invention, been constructed in such a manner that the whole centre of gravity of the whole system does not alter its position while the machine is in motion. Each stirred element works together with another stirred element in such a manner that the counter powers which occur in each fraction of time keep their balance.
For this purpose the machine has, through this invention, been symmetrically divided through its vertical centre. Both parts contain a spindle symmetrically arranged which are connected with each other by'means of cog-wheels, in this 40 manner rotating in the opposite direction. On both spindles eccentrics are arranged which are connected with the agitating-plate by means of connecting rods. Through this symmetrical arrangementof the two halves of the machine with opposite direction of. rotation, and vibration of the stirred parts, a good compensation isobtained.
Further, through the invention of this machine in order to obtain a perfect compensation in each of the two symmetrical halves, a counter mass to the stirred parts is provided which regarding the axis of rotation balances with the mass of the eccentric, the connecting rod, and the-according parts of the agitating-plate as well as the joints belonging to it.
spindles, for instance by means of By way of example an embodiment of the invention is illustrated in the accompanying drawing in which similar characters of reference denote corresponding parts in all the views and in which- 00 Fig. 1 is a front view of the machine;
Fig. 2 is a side view of the machine;
, Fig. 3 is a sectional view taken on line x--x in Figs. 1 and 2;
Fig. 4 is a sectional view taken on line Y-Y in.Figs. 1 and 3. i
The machine, whichis symmetrically divided through its vertical centre plane, carries the heavy horizontally placed agitating-plate p, which is provided with vertical rods 0, and is by means of this frame b, moved in a vertical direction. The two spindles rest in four bearings e, firmly connected with the frame. On these spindles are affixed symmetrically arranged the two cog wheels 2, working into each other; centric k, as well as the two fly wheels s, with the counter masses w. Through the two connecting rods 1, the movements of the eccentrics are transferred to the link pin 0 and the agitating-plate p. The drive is executed through one of the a bandpulley i.
The radii of eccentricity and the radii of the circles of the centre of gravity .of the counter masses, as well as the masses working at these radii are proportioned so that the counter mass which acts on radius FW Figure 4 in the centre of gravity W balances with the mass-of the eccentric K acting on radius FK in the centre of the eccentric with the mass of the connecting rod e, and the according part of the agitating-platep, as well as its link pins 0 and guide pin a.
When the device is put in motion all components compensate which result from centrifugal force, acceleration, viz inertia and retardation, because they are equal and directed opposite. The machine keeps even without being fastened in its place, and works even at highest speed without shock.
Instead of one pair of fly wheels any number of 1 fly wheel pairs with eccentrics and connectingrods can be arranged on accordingly prolonged spindles.
The invention having been set forth what isclaimed new and useful and is desiredto secure 1 by Letters Patent is:
1. In an agitating machine for producing concrete bodies in molds, the combination of a frame,
a heavy agitating plate horizontally arranged above said frame, rods for vertically guiding said the ec- 75 g plate relative to said frame, four bearings firmly connected with said frame, two spindles disposed parallel in said bearings and rotating in opposite directions, a common drive for said spindles, said spindles carrying each in symmetrical arrangement a connecting means, an eccentric and a flywheel, and connecting rods and links for transmitting the motion of said eccentrics to said agitatingplate, all moving parts cooperating so as to cause all forces to balance each other to MARTIN STUHLER.
