Is Simple in Construction.

There is being placed on the market
this week by the National Machine Co.,
Inc, of Brattleboro, of which Arthur f.
Roberts is president, an automobile jack,
the manufacture of which gives promise
of becoming an important addition to the
industrial activities of the town. The
jack is a marvel in the way of automobile
accessories, and engineers to whom it has
been submitted regard it as the best jack
they ever examined. A picture of it is
given on page eight of this paper.
1t certainly is a. sturdy little device,
easily operated and built for execution,
and 10 has a lifting capacity that has sur
prised everybody who has tried it out.
At the Boston automobile show it lifted a
weight which men interested in another
jack wagered would break it down, and
IN Bratteboro young woman raised a
ton with it with surprising ease. Two OF
them have been sent to an automobile
factory to have their capacity tested
\ number of these jacks have been
placed on exhibition in the window at
the Robbins 4 Cowles store. They have
been designated Benedict Jacks because OF
their inventor, Henry |. Benedict of New
York, and the National Machine Co. has
entire control of their manufacture and
sale, which is being done on a royalty
| basis. Howard j. Ayers of Boston has
sales manager, and he has been at, the
factory this week
A shipment Of SEQ jacks, the first ship
| r.
on Elm street 80 jacks day are being
made at present. There is every reason
to believe that the output will inereas,
/ rapidly, and with the present equipmen
the company can put out 100 to $50 daily
i The whole upper floor and part of tht
first floor are devoted to the manufacture,
of this implement
| The Benedict jack is of the universe
type, that is, it is instantly adiustabl,
to any make of car, having a range o
from nine inches, when the screw is dowl
to the lowest point, to 20 inches when i
is fully extended, and the whole thin
weighs but u pounds.
4 There are but three working parts
which reduce to minimum the possibili
ty of trouble, and these parts are mad
pf hardened steel, so that extraordinar,
conditions would be required to break on
of them When shipped they are packe,
in cartons about the size of package Q
: breakfast food
The three working parts of the jack ar
these: A screw which extends or reduce
the jack; a worm gear which meshes th
screw; and worm which meshes the gear
The worm is operated by a long eollaps
ible handle, four turns of which extend
the jack one inch This handle operate
: easily by reason of a ball bearing en-
Z thrust bearing, and it is instantly al
: taehed or detached without the necessit
! of operating any mechanism, and whe
attached the jack may be pushed unde
any part of the car without the operate
squatting down.
The base is broad and prevents tippin,
is adjustable, giving three ranges of heigl
, before raising the screw, and when tl
, weight is removed simple quick releas
lever operated by thumb and finger allow
the screw to drop quickly into the bas
and the jack is ready to put away. Thel
