Patented Dec. 18, 1934 PATENT OFFICE DESCALEB Samuel S. Roberts, Pittsburgh, Pa.
.Appli'cation May 24, 1933, Serial No. 672,693 eolaims. (or. 29-81) This invention is a descaler, one of the objects being to remove scale from slabs, blooms Other objects may be inferred.
Referring to the accompanying drawings illustrating a scaler:
'Figure l is a transverse cross-section.
Figure 2 is-a longitudinal cross-section.
Figures 3 to 6 are enlargements of various details shown by the first two figures.
Shafts 1 are journaled in a frame 2 in a manner generally similar to that of a rollingmill. That is to say, the frame includes windows carrying bearings 3 in which the shafts are -journaled' in spaced relationship, the lower one being fixed and the upper one being adjustable by screws 4 driven by amotor 5.
Both the shafts are driven by a motor 6 through a gear box '7 and spindles. 8, the upper one of the latter vibrating to accommodate the upper shaft. However, the gear box 7 differs from the usual form in that the motor 6 directly drives a pinion 'l engaging gears [7 so that the shafts revolve in the same direction, instead of oppositely as in the case of 'a mill.
A roller table 9 carries the work between the two shafts. As. these rotate in the same direction they cannot feed the work between-them by their driving forces; hence, a pusher 10 is provided for this purpose. This pusher depends from a carriage 11 which runs on elevated tracks 12 over the table 9. Driving is efiected by a motor '13 geared to a pinion 14 which. engages a rack 15 fixed to, or forming a. part of, the tracks 12.
The rotary shafts 1 peripherally carry lateral rows of impacting elements 1. Thus, when' the work is pushed between the two by the part 10, these impacting elements hammer and scrape on its surfaces to remove, the scale. Since scale.
is generally very uneven and the work may even contain pits or holes where imperfections have been chipped out, these impacting elements should be of a design whereby they may effect complete cleaning.
According y, they comprise wheels which are mounted in lateral rows by lateral axles 16 which are, in turn; carried by the shafts. The wheels fit the axles sufliciently loosely to permit them to individually radially move respect: ing the shafts. This means that they are individually able to clean specific example of the new deany depressionsin the are wheels having radially corrugated peripheral portions 1 and flat hub portions 1, the latter loosely fitting the axles 16, as mentioned. The elements are arranged sufliciently closely so their corrugated portions are mutually internested, yet their hub portions 1 function to limit this to some extent. That is to say, thisinternesting is limited to such an extent that, although the elements corrugated portions'mutually internest, they may individually disengage upon impact with the 'work and thus let the elements accommodate themselves to pits or depressions therein. I
In another form of the invention, the elements may, in alternate rows, have internesting radial corrugations and alternatelyhave, in the other rows, radial corrugations and flat sides, this last being illustrated by Figure 4; showing the modification. This assures hammering and scraping action completely across the width of the work, yet at the same time provides sliding surfaces, in the rows provided with the wheels having fiat sides,v whereby the individual elements may move radially respecting their mountings.
In the forms illustrated, the axles 16 are mounted on the shafts by spiders 17 keyed to the latter. An integral construction may also be used. As the impacting forces of the ele- ,7.
mounted for individual radial movements respecting their rotary mountings. In the case of 'the' wheels disclosed, this is effected by providing the elements with a hole substantially larger than the axles. If segments of some-form or other he used, other forms of mountings are indicated. Also, if only one side of the work is to becleaned of scale, only one of these mountings carrying such elements is needed.
From the foregoing it will be seen that the invention generally consistsin providing at least one rotary mounting peripherally carrying impacting elements. These impacting elements are peripherally carried inlateral rows,'have laterally sinuous hammeringparts and areindividually radially movable respecting their carrying mounting. They are arranged sufiiciently closely to internest to some extent and thus provide overlapping hammering and scrapin sllrfnnag Upon impacting the work they tend to rebound, whereupon the centrifugal force immediately returns them to a dragging contact with the work.
I claim:
1. A descaler including a rotary mounting peripherally carrying circular elements havin radially corrugated peripheral portions and being arranged in lateral rows with their axes substantially parallel to that of the mounting. said elements being arranged sufliciently closelyto efiect limited interengagement of their corrugations.
2. A descaler including a rotary mounting peripherally carrying lateral axles which themselves loosely carry rows of wheels having radially corrugated peripheral portions and flat hub portions, 'the latter functioning to permit individual movement of the wheels on the axles bylimiting internesting of their respective corrugated portions. 4
3. A descaler including a rotary mounting peripherally carrying lateral axles which themselves loosely carry rows of wheels, the latter having internesting radially corrugated peripheral portions in alternate rows and alternately having, in the other rows, radially corrugated peripheral portions and fiat sided peripheral portions. v
4. A descaler including a frame journaling rotary mountings in spaced relationship for the passage of work therebetween, said mountings each carrying spaced lateral axles which themselves loosely carry rows of wheels having radial corrugations extending to their peripheries and being arranged for partial mutual internestin and individual disengagement, the latter normally occurring upon impact with the work.
5. A descaler including a frame journaling' rotary mountings in spaced relationship for the passage of work therebetween, said mountings each carrying spaced lateral axles which themselves loosely carry rows of wheels having radial corrugations at their peripheral portions and.
flat hub portions, the latter portions functioning to limit internesting of the first named portions.
6. A descaler including a frame journaling rotary mountings in spaced relationship for the passage of work therebetween, said mountings each carrying spaced lateral axles which themselves loosely carry rows of wheels having radial corrugations at their peripheral portions and fiat hub portions, the latter portions functioning to limit internesting of the first named portions, and said mountings being provided with means for rotating them in the same direction and means for pushing work therebetween for cleaning by said wheels.
7. A descaler including a rotary mounting peripherally carrying hammering elements arranged in spaced lateral rows, said elements in each of said rows being proximately arranged peripheral portions and fiat hub portions, the
latter portions being constructed to limit internesting of the first named portions.
9. A machine for removing scale from steel prior to its rolling, including the combination of a frame having windows, bearings carried in said windows, screws for adiusting the distances between said bearings, rotary mountings journaled in said bearings, and lateral spaced rows of hammering elements carried by said rotary mountings, said elements having mutually internested corrugations at their peripheral portions.
