VIBRATOR FOR DENTAL USE Filed Sept. 24, 1935 Patented July 28, 1936 PATE 'T OFFICE 2,4s,75e VIBRATOR Fon DENTAL USE John E. Shultz, Pella Iowa Application september 24, 1935, serial No. 41,932
1 claimt co1. 248-121) My invention relates to a vibrator intended for use by dentists in. making plaster solutions, casts' and the like.
It is the purpose of my invention 'to provide a very simple and inexpensive vibrator, whichcan be used in connection with a. motor found. in eyery dentists office for vibrating materialfor making casts.
A further purpose is to provide such a; vibrator having a base portion on partV of which a motor may be placed for steadying the vibrator and holding it in position, and having also an upright member to which is hinged a shelf, yieldingly held in position to be vibrated.
More particularly, it is my purpose to provide such a vibrator, comprised of a single piece of sheet metal, with parts bent in opposite directions to form a base, on part of which a motor may be supported, and having an upright portion provided with a recess through which a vibrator supported by the motor may extend, and having a shelf hinged above said recess on the opposite side of the upright portion from the base, which supports the motor, and provided with a spring, by which the shelf may be yieldingly held in substantially horizontal position.
Another object is to provide in such an upright portion a recess to receive the spring, when the shelf is folded up to position parallel with the upper part of the upright, and to provide a latch for holding the shelf in its folded position.
With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my vibrator for dental use, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawing, in which:
Figure l is a perspective View of a vibrator embodying my invention.
Figure 2 is a side elevation of the same with the motor resting thereon, part of the shelf being shown in section.
Figure 3 is an end elevation of the rotary vlbratory device on the motor; and
Figure 4 is a perspective view illustrating the shelf in raised folded position and held therein by the latch.
My vibrator may be made in various forms and of different materials, but for cheapness and simplicity, I have built it of sheet metal.
A single sheet forms the upright member I0, at the bottom of which a portion II is bent to horizontal position in one direction, and portions I2 and I3 are bent to horizontal positions in another direction.
It will be seen that the portions I2 and I3 may support amotor I4 by which the vibrator can be held in place and which provides the meansV for vibration.
The upright Ill is formed with a recess I5'. A shelf I6 is hinged to the upright above the recess I5. An expansible spring Il is fastenedv to the shelf Hi and to the upright lll at a point above the hinge line of the shelf.
The shelf is arranged to swing' or fold from substantially horizontal position4v as shown in Figure 1, where it serves to support a receptacle for Vibrating the contents thereof upwardly to position against and parallel with the upper part of the upright Ill as shown in Figure 4. When the shelf is so folded upwardly, the device may be stored on a shelf, and other articles can be placed on the members I I, I2, and I3, and the vibrator will occupy a minimum amount of room.
The upright member I is provided with a recess or hole i8 above the hinge line of the shelf to receive the spring Il, as shown by dotted lines in Figure 2, when the shelf is folded up.
A swinging latch I9 is pivoted to the upright member Ill and may be swung to position for holding the shelf I6 up as illustrated in Figure 4.
On the under side of the shelf I6, I preferably fasten a sheet of rubber or the like 20 as a noise deadening member.
The motor I4 is provided with a spindle 2| adapted to be mounted on the motor shaft 22 and provided with an eccentric disc. 23 made of wood or any suitable material.
When in use, the shelf I6 is lowered to substantially horizontal position. The vibrating wheel is installed on the motor and the motor is set on the base members I2 and I3. This helps to hold the vibrator properly in place and also makes it easy to adjust the motor to proper position for functioning.
The spindle 2l is extended through the recess I until the disc 23 is underneath the rubber sheet 20 on the bottom of the shelf I6. Then a rubber cup or the like 24, containing the solution of water and plaster of Paris for example can be placed on the shelf I6 and held in position by hand.
The motor can be operated for vibrating the shelf. The spring is preferably so tensioned that it will normally hold the shelf slightly above the disc 23. Then when the dentist or his assistant puts the cup 24 on the shelf and presses down slightly, he can bring it into operative relation to the disc 23.
The dentist then has one free hand for stirring the mixture or for adding to the ingredients thereof.
Similarly this vibrator can be used for pouring casts or for pouring plaster solution into molds. Y
The purpose of vibration, of course, is to eliminate air from the plaster of Paris solution or the casts', for thus getting a production' of uniform density.
When the vibrator is not in use, the motor can be removed and the shelf I6 folded up to position where it is against the upper part of the Vupright I0, whereupon the spring I1 will project through the recess I8. The latch I9 may be used for securing the shelf in its upright position. The entire device may be then set out of the way until it is needed again.
It'maybe understood that the motor can be set on the portions l2 and I3 and both the motor and the vibrator bolted or screwed to a table or bench or support. Then when the vibrator is not needed and it is desired toh use the motor for other purposes, the shelf may beraised andheld in upright position by means ofthe latch I9, and thereupon K the Ymotor can be used-for other purposes.
30 ments, such as'bu'f'ers, grinding stones, polish- The disc 23. can be removed and other impleing wheels and so on may be substituted. In this way the vibrator and motor can be fastened permanently to the laboratory bench and yet the vibrator will not interfere for using the motor for any purposes other than vibrating, for which it may normally be employed in a dentists oiice.
Changes may be made in the material used and in the shape, construction and arrangement of the parts of my improved vibrator, and it is my intention to cover by my claim, the use of any materials suitable for the purpose and any modiations in form, structure or arrangement of the vparts whichfmay be reasonablyincluded within the scope of such claim and within the scope of my invention.
I claim as my invention:
In a'vibratorA for dental use, a single piece unitary standv or support having an upright member andoppositely extending base members, said base members being adapted to rest on a table or the like. and one of them being adapted to receive a motorplaced,thereon, the upright memr ber havingarecess to receive the motor shaft or` a tool thereon;y a shelf hinged to the upright member above the, recess to swing from substantially horizontal ,"postionV to Vupright position adjacent the upright member above the recess, a coil spring connected at one end tothe shelf and at the other end to theuprig'ht member above said recess, said-` upright member having an opening to receive the spring when the shelf is swung toward its upper position.
