Luther Hummer Tool Grinder 
Here is a tool grinder that is a whole workshop in itself and it is low enough in 
price for everyone to afford. It makes-every bit of your everyday work so much 
easier—it saves your time and money in so many different ways that no farmer or 
tool-user should fail to find out every fact about it. No other machine ever built is 
like it or approaches its wide range of usefulness—no other machine of so moderate 
a price will save you so much money and work. We want you to try this wonderful 
machine for 30 |days free on your farm without any promises or red 
tape. You can sharpen and polish all your tools and try it out in every 
way. Then if you do not want to keep it send it back. Our big 40-page free 
book tells all about this machine and its uses. 
Dimo-Grit Wheels—“the wheel for steel.” 25 times faster 
than grindstones—10 times more efficient than emery. 
Will not draw temper from steel. 
Dimo-Grit cuts away hardest steel as emery does soft copper. These wonderful sharpening wheels 
turning 4000 revolutions per minute, will quickly do any job of sharpening. Compared to grinding 
on a grindstone it is mere play to do the toughest job of grinding with Dimo-Grit wheels—the “wheel 
for steel.” No need of cooling with water—no danger of drawing temper. No more spoiling 
of tools, no more back-breaking work on the grindstone. Think of how much easier your every day 
work will be—how much better and quicker you will do it with all your tools keen and bright. Dimo- 
Grit is the latest development of artificial diamond substance, a twin product of Carborundum you 
have heard so much about. But Dimo-Grit is especially suited to steel. Carborundum wheels 
furnished if wanted. McClure's Magazine’s intensely interesting story about the discovery of artifi¬ 
cial diamond substances is told in our Free Book. 
A whole workshop in itself 
With this machine you can do every kind of sharpening, grinding 
or polishing—you can sharpen ensilage knives without removing them 
—run the chum and cream separator with half the effort and save 
your back. The milk tester will help you sort out unprofitable cows 
($ of all cows are milked at a loss). With the special attach¬ 
ments the Hummer can be used as a jig saw, rip saw, turn¬ 
ing lathe, drill or horse clipper. Has 30 different attach¬ 
ments from which you can select any number of attach¬ 
ments you need. It saves money in countless ways—it does all 
sorts of repair jobs on which you would otherwise waste time and 
money in taking the job to town. The free book fully shows the 
many ways the Hummer saves money for you, and how it pays for 
itself over and over again. No other machine ever built saves so 
much hard work and so much money in so many different ways. 
Shaft drive like an automobile 
Look at the mechanical picture in the left-hand corner of this ad¬ 
vertisement—see what strong construction this machine has—notice 
how the easy running shalt drive is enclosed in dust-proof housing— 
you can see why this machine will give long service. Its shaft drive, 
ball bearings, bevel gears and gravity feed lubrication make it run 
as easy as a sewing machine. 
Makes anyone an expert at tool 
sharpening 
The patent tool rests and special - attachments enable even an in¬ 
experienced boy to do the most difficult sharpening, such as twist 
drills, saws, discs, hay knives, mower knives* etc. —any and 
every job of sharpening and grinding. You expect to use tools every 
day for years. Consider how much easier and quicker this wonderful 
machine will make all your work—how much money it will save! 
This machine will help keep the boys on the farm. It 
lightens their work and makes it a pleasure—makes them 
forget the lure of the city.

More Than Claimed For It. 
The machine is all and more than yon claim for 
it. I find more uses for it every day. 
Vic. Anderson, Bay Shore, L. I., N. Y. 
Used Grinder Five "Years. 
About six years ago I purchased a Grinder of you 
whicti is still giving most excellent satisfaction, 
and I find it a very useful machine to have on the 
farm. Henry O. Turner, Oazenovia, N. Y. 
Friend Laughed at First. 
Have given the Grinder a good test. It does all 
you claim it to do. Some of our friends laughed 
and said we were foolish for sending for it, because 
it would be no good. One of them was here when 
we were trying it and said he thought it was well 
worth the money we paid for it. He thinks he 
may get one after a while. 
Orlo P. Hebding, Darien Center, N. Y. 
Friend Wants One, Too. 
Well satisfied with the Grinder. It cuts as fast 
as you claimed it would. I have a friend of mine 
who does repairing and he was well pleased with it. 
He wants to know if you could supply him with the 
same machine. E. J. Morris, Flushing, N. Y. 
Machine Is a Wonder. 
The machine certainly is a wonder and the best 
I have ever seen, and so pronounced by others who 
have seen it. Chas. D. Snyder, Saugerties. N. Y
