v 6 Claims.
This invention relatesto exhaust devices, more particularly to exhaust tables for brushing vitreous enameled products, such as parts of an electric range, and it has for its object the proa vision of an improved device of this character.
In accordance with this invention, an exhaust chamber is provided. Arranged above this chamber are a plurality of spaced apart members having surfaces inclined downwardly toward the 20 vention, reference should be had to theaccompanying drawing in which Fig. 1 is a perspective.
View illustrating an exhaust device arranged in accordance with this invention; Fig. 2 is a front elevation of the exhaust device of Fig. 1; Fig. 3 25 is a side elevation of the exhaust device of Fig.
1; Fig. 4 is a fragmentary perspective view illustrating aportion of the exhaust device of Figs. 1, 2 and 3; Fig. 5 is an elevation, partly in section, of a portion of the device shown in Figs. 1, m 2 and 3; and Fig. 6 is a sectional view taken through the line t-t of Fig. 5 and looking in the direction of the arrows. I
Referring to the drawing, this invention has been shown in one form as applied to an exhaust device comprising an exhaust table it). This table comprises a substantially rectangular support H, which, as shown, is provided with a pair of front and rear walls and a pair of side walls joined together in any suitable manner. M The support it in turn is supported by means of a plurality of legs 02 arranged at the corners. Arranged longitudinally of the support H from the front to the rear wall thereof are a plurality of spaced metallic members it having substana5 tially the shape of an inverted V. As shown,
there are three of these members arranged between the side walls of the support. Adjacent the side walls of the support are a'pair'of metallic members It inclined downwardly from the so upper edges of the side walls and inwardly toward the members i3, as shown in the drawing. These members it are also spaced from the adjacent members l3. The spaces between the members l3 and M are designated by the numeral Ma. 55 Arranged below the members Hand it is an exhaust chamber l5 which is connected with asuitable exhaust conduit 16. It will be understood that the conduit lli will be connected with a suitable exhaust device (not shown) arranged to create a low pressure in the exhaust chamber. 5 While the members it and It are shown in the drawing arranged longitudinally of the support i i, it will be understood that they may be positioned transversely of the support. When the members are positiond'longitudinally of the sup- 10 port, it is preferable that the spaces Ma between the members be somewhat wider at the front of the device than at the rear. For example, the
- members It and it may be so arranged that they touch each other at the rear, as shown in Fig. 1, while the space between the members varies gradually from zero at the rear to the widest portion which is located at the front. This arrangement has the advantage that' more air is exhausted from the work table at the front where the operator works than at the rear, which, of course, is very desirable.
Supported by the front and rear walls of the support it are a pair of rails l'l which in turn support a work carriage it. The work carriage, as shown in the drawing, is of openwork construction, being formed by a rectangular frame it to which wheels 22 are attached. The wheels 2t, as shown, ride upon the rails ii. The carriage it, as shown, is arranged to move longitudinally from the front to the rear of the support it on the rails ill. The carriage it supports an openwork supporting tray 2i for the work'articles that are brushed. The tray 2i, as shown, is also of openwork construction, and is made of a rectangular wire 22 which is somewhat larger than the rectangular support it. The corners of the wire 22, as shown, are joined to a hub portion 22 by means of wire spokes 22. The hub 22 is mounted upon a stud 25 (Figs. 5 and 6) which 40 is supported by means of a supporting collar 2%.
.The collar 26 is supported by means of arms sphere and slots function as means to hold the latch in each of four positions spaced 90 apart.
)It will be observed in View of the foregoing constructiomthat the work which. is positioned upon the tray 22 can be rotated relative to the carriage l8, and furthermore, can be moved longitudinally relative to the frame II on the carriage l8. This construction has the advantage that the work to be brushed may be turned on a vertical axis and may also be pushed forward and backward for the convenience of the operator, and also in order to keep the parts being brushed always over the most powerful exhausting area, which as has been pointed out previously, is at the front.
In order to exhaust the loose enamel parts, etc. of the work being brushed with a minimum quantity of air, it is necessary to direct the air flowing in over the work table about the area being brushed at a relatively high velocity. In order to assist in this, a suitable hood 2B is provided about the work table.
The hood, as shown, surrounds the support H, and at the front is provided with a wall 29 which has substantially the same height as the front wall of the support H and which is spaced somewhat therefrom, as clearly shown in the drawing. The hood is also provided with a side wall 30 which is spaced from the corresponding adjacent side wall of the support H, but which is considerably higher than this side wall, as more clearly shown in Figs. 2 and 3. The walls 29 and 30 flare outwardly from the corresponding walls of the support, as shown. The front wall 29 and the side wall 30 are connected with the exhaust chamber l at points below the lower edges of the corresponding front and side walls of the support II so as to provide exhaust ports 3| and 32 below these walls of the support. The front wall 29 where it joins the side wall 30 is provided with an outwardly flared portion 33.
In addition to the front wall 29 and side wall 30, the hood is provided with a side wall 34 opposite the side wall 30. The wall 34 is positioned against the adjacent side wall of the support ll, rather than being spaced from it. The hood also has a similarly arranged rear wall 35 positioned against the rear wall of the support I l. The walls 34 and 35 extend upwardly to the same height as the wall 30, and both side walls 30 and 34 and the rear wall 35 are provided with an inturned substantially horizontal flange 36.
In other words, the hood is closed at the three sides but is open at the front for the convenience of the operator. The inturned flange 36 at the top is so arranged that air that is drawn in at the top is directed in a downward direction over the part that is being brushed away from the operator into the exhaust chamber IS. The opening provided in the top of the hood should be only large enough for the convenience of the operator in handling the work. The side walls 30 and 34 and the end wall 35 flaring outwardly from the support ll provide space for relatively large parts to be brushed, the particular work area being brushed always being placed at the forward part of the hood by the operator by properly manipulating the carriage l8 and the tray 2|. The walls 29 and 30 of the hood are spaced from the corresponding walls of the frame H to provide room for free movement of the operators hand in brushing the edges of the work piece. If the operator be left-handed, the left'hand wall of the hood should be spaced from the frame. The flared portion 33 serves to catch loose enamel which is wiped from the work when the operator draws the hand toward the front. Y
It 'is to be noted that the angular members l3 and I4 are so arranged that the loose enamel slides down their inclined surfaces into and through the spaces Ila into the exhaust chamber I5 away from the operator. This is accomplished by a relatively small quantity of air which flows through the spaces u with a relatively high velocity.
It. is also to be noted that the work tray 2| is so arranged that it can be conveniently manipulated by the operator in order to bring the part that is to be brushed directly before him at the front of the device.
Economy in air consumption is increased by the arrangement of the hood which provides for the flow of air directly downward away from the operator through the work table Hi, the opening at the top of the hood being just large enough to provide enough room for the operator to conveniently handle the work.
While I have shown a particular embodiment of my invention, it will be understood, of course, that I do not wish to be limited thereto since many modifications may be made, and I, therefore, contemplate by the appended claims to cover any such modifications as fall within the true spirit and scope of my invention.
