Berkel slicer model 7 was produced at the same time as the model 5, all the mechanics is identical to the model 3 – 5 while the dimensions of the base have been increased in height.
In the first two years Berkel Model 5 was built simultaneously with the previous Mod. 3. That is why some features are common with both slicers and in particular:
- the vice that fixesthe product to be sliced is inserted by a slot on the shifting cart, and in the back side there is a small column with a clutched handle. While at the front side it consists of a rack rod;
- the sharpenerconsists of a closed chrome plated tin and has two clicks to sharpen the blade.
Then the fixing vice has been modified with two crossed small columns with clutched handles, connected by an “L” shaped toothed arm.
The sharpener is more simple and modern and is covered by a painted cap.
While compared with the Mod. 3, the following parts have not been changed for the whole production:
- the base;
- the slice adjustment clock;
- the shifting cart.
The closed flywheel, with embossed writings, puts into action a gearing placed under the base and it drives both the blade (by means of a chain) and the shifting cart (by means of two connecting rods).
The machine has a shifting cart that, close to the blade, shifts inside a hub.
While, at the opposite side, the cart leans on a square rod thanks to a shifting felt. The two guides are supported by four small columns fixed on the base, two for each guide.
This system was adopted the first time in 1908 with the very charming Mod. 2.
The slice adjustment clock is fixed on the base of the machine and puts a bill shaped lever into action, placed on the cog-wheel shaft located on the cart. This one then puts
the endless screw into action where the vice comb is inserted that generates the slicing movement.
The cog-wheel is connected to a crank that, when is moved by hand on the right or left, shifts the vice consequently, as you like.
The hub supporting the blade is fixed to the shoulder, which is flattered outside with a wing shaped arch. This allows to lengthen an opal glass top tray, so you can manage more laying surface.
