835. Speed indicator, measures revolutions, you divide by the time to
836. Stumped (of this I'm sure)
837. Possibly what is essentially a large wood sharpener to make wood
shavings to use in starting fires
838. See 836 - another stumper. Looks vaguely Veritas or Lee Valley
839. Top of a lighter - the wheel strikes the flint
840. Military climbing piton
835 Tach. ... Tachometer... Shove point on the left into a hole in the
center of a shaft. Pull trigger to engage worm drive. It counts
revolutions. Wait a minute. Release trigger. The result is
revolutions/minute = RPM.
839 Clock pendulum weight.
Home today due to weather.
835. This is for measuring RPM.
836. Looks like the leverage is set to spread or push something
away from a square drive/bolt/nut. Beyond that no help.
837. Counting or sorting box
838, Compass, trammel points, ball point pens for drawing
839. clock pendulum with an adjustment to fine tune the timing.
Keep the whole world singing. . . .
837. Counting box used by secret societies (fraternities, etc.). White balls
and black balls (actually black cubes) are kept in one side. Members "vote"
on new members by choosing either the ball or cube and secreting it into the
other side. Unfortunately, the "balls" sounded differently as they
dropped... so there was no real secret ballot.
Item 835 - an early "tachometer", used by placing the pointed end (it
was made with a three-sided point, so it wold hold without slipping in
the center-drill hole of the shaft-end) of the rotating spindle or on
the end of a rotating shaft, timing it with a watch (sweep second hand
made this better), reading the three-digit dial to obtain the number of
revolutions in the elapsed time, and simply multiplying or dividing to
obtain the resultant RPM.
Item 836 Well, it's a ... er, um, well, ah ......
Item 837 A voting box - from a lodge or other social society or
organization whose admission to membership was subject to the unanimous
vote of the members. It was of wood, the box being divided into two
sections. It contained a number of marbles, the majority of which were
white, but with a significant number of black marbles included.
The lid with the funnel-shape slid from end to end, and only in the one
position, would it uncover the divider, which allowed all the marbles
to be rolled into the end with the handle. The divider was then
lowered, the lid slid to the voting position, and an officer
(sergeant-at-arms, usually) would take it to every member for his vote.
Voter would select one marble and place in the funnel. The box, being
wood, made it possible for all to hear only one marble drop.
The box was returned to the executive chair, and in the presence of the
executive committee, votes were counted. A finding of all white
marbles usually admitted the candidate. One "BLACKBALL" usually denied
membership. Perfectly anonymously.
One of my uncles came home from lodge-meeting, one Monday night, mad as
he could be. Auntie asked him what made him so mad, and he said, "Well
"so-and-so" was put up for membership, and I couldn't vote."
Auntie said, "Well, why ever in the world couldn't you?"
Unk roared, "By the time the vote got to me, all the damn black balls
Item 838 Another mystery.
Item 839 A pendulum-bob from a clock. The knurled wheel (nut) was
used to raise or lower the bob, thus shortening or lengthening the
period of the swing. The locking screw at the top prevented its
drifting out of adjustment.
Item 840 An anchor of a sort, driven into a mortar seam of a
masonry structure, that other things may be attached thereto.
(Drain-spouts, temproary lantern-hanger, etc)
Now to see what you others "guessed".
Revisiting 836 with some observations that might help someone identify
it, since I surely can't.
The side "wings" are either meant as a depth stop or for centering.
The Graduated notches occur along a curve and there's a can-action
clamping mechanism to increase the leverage and the jaws also have
linkage to increase the leverage - a few orders of mechanical
advantage. In usage the cam-action clamp would start in the notches
closest to the jaws, the cam operated sequentially and moved up the
notches. There's a flare at near the top of the handle at the cutouts.
It seems to be some sort of crimper as there is no real readily
observable way to grasp or twist the tool.
What would require a square crimped cap, or that would require such
mechanical advantage without the need for turning it, I have no idea.
According to R.H. :
O.K. Posting from rec.crafts.metalworking as usual.
835) This is a fancier version of the hand-held tachometer (RPM
counter) which has been made by Starrett (and many others) for
It looks as though the trigger allows the gears with the
readouts to pop clear of mesh with the worm gear when your watch
reaches a precise elapsed time.
I wonder whether there are provisions for engaging the worm with
the trigger as well -- to make it possible to engage the diamond
point with the shaft before the counting starts, then engage the
gears as the second hand sweeps past zero the first time, and
disengage as it sweeps past zero the second time. Then you read
the total number of revolutions off the dials -- with the bigger
one counting two digits, the medium one counting one digit, and
the little one counting the most significant digit -- perhaps up
to four or five (for 4000 or 5000 RPM max).
836) Looks as though it is designed to grip a (square-ended?) shaft,
and hold it centered in a larger hole.
837) Hmm ... perhaps used in the process of making stereograph
images -- one side at a time?
838) Hmm ... it looks a bit new for the style. Otherwise, it sort
of looks like a wrench for turning something with two pin holes,
but not with much torque. Is the black part plastic, or ebony?
839) Pendulum bob for a clock -- probably a mantel clock, given
the size. The knurled wheel visible rim-on in the center is
used to move the bob up or down the pendulum shaft by small
amounts to tune the speed.
840) It sort of looks like a tiny fork-lift fork attached to a
lifting ring -- so my guess is that it is slid into slots near
the bottom of something and attached to steel ropes to lift
it with a crane. And the "something" seems to be of military
construction, based on the "U.S." stenciled on the blade.
Now to see what others have said.
Most of them have been answered correctly this week:
835. Speed indicator
836. Axle nut wrench
837. Blackball ballot box
838. Fisherman's blood knot tying tool, the black part on this one is made
839. Clock pendulum
840. Mountain climber's piton
