e Hman D. Acnance I NND .DANIEL Brenn, orf LLEWELLYN, PENNSYLVANIA. j
Letters-Patent No; 107,872, dated October 4, 1870.
TheSchedule referred to in these Letters Patentrand making part of the same' Be` it known that .we,HInArr D. CHANCE and DANIEL Risen, tot" Llewellyn, in thc county` of Schuylkill and State of` Pennsylvaniahavc invented anew and `improved SawfFiling and Setting Machine; audwe do' herebyfdeclare that the following isa full, clear, and exactdescription thereof', which will enable others "skilledfin the `art to make and use the same, referenee` 'being had to the accompanying drawing `formingpart lofithis specication.
M y `invention relates t` tingsaws,and",` l l My 'object' is tointroduceito the publie certain im? provenient-sithereon, which will irst` begdescribed in connectionwithall that is necessary to a full under. 'standing` tl1ere`o`l",` and then be clearly specilied in the elaim.Vv .i v h `lligurel is plan `View of our improved apparatus.

Figure@ lis a cross-section on the line s 2 of 4-` @Figure G is sectional elevation of the nie-holder;
andi.
.lfigure 7 plan of one ef `thejplatesused for attaching tlie'clampingbars tothe bench.Y
Similar' letters of reference indicate corresponding parts. l .g l j l j `Akrepresentfs a pair of clamping-jaws for holding saw for tiling, the saw,beingclampedlbetween them .bythescrews the `said jaws `being heldin `a vise, `orthey may bea-ttached to the side'of bench, IG, by
ineans offthcQscrews o rfpius Dfengagingwith the ,slotted'plates E fitted in the' side of thebenclnand receiving `the heads'throughthe large parts F, after which the jawsare moved so as to engage `the heads n of thepins behindjthe plates at the narrow part of theslots,`inl annanner well known.` It is intended that boththe jaws be fprovlded with these pins, so Vthat thcjjawslnay be readilyturued and attached for holding eiiherjsideof `the saw to the workman.v
" Each jaw isprovided with aplate, G, on the top,
the outer edgcoffwhich `is beveled for `iittingin the grooves ofthejslidc-rest H, the bridge Land the block K ofthe setting apparatns, of which L" is the` sliderest. l
Theseplates are alike as to width, thickness, and
j arrangement with the jaws, so that the slide-rest and way, and will itthesame. n Y
`The.slide-restI-I is litted to work Aloosely on the guidefplate G, and carries yokes or eyes M, in which other devices working on .them may be'applied either a pendent foot-strap maybesuspended by hooks N,
dmachines for filing and setfor the operator to clamp the slide-rest rmlyat any point by pressing .with his foot down upon the said foot-strap.
j O is'a tile-stock holder; it is hinged to Vthe slide` rest at l), so as to project along the saw, above which it is `supported by the temper-scrcwQ.
I This 'stock has two boxes or supports, R, for the file-stock, suspendedfrom the under side by clamping pins S, arranged inthe curved slots T, so' that they can be adjusted for holding the tile-stock ati any angle required .relatively tothe saw.
,l The tile-holding stock consists of. afbar of metal .fitted to the boxes or--bearings 1t, to slide back and 'end ot the center for turning it to shift -the file.
A' isapawl, pivoted adjustable to the ears B on the' top of the le stock-holding plate 0,aud so arranged that when the said plate O is raised on the hingejoint it will push backward the free end of this pawl rests in a groove, C', in the top ofthe bridge I, which groove terminates by a strongfwall, D', against which the pawl will strike when moving back. This bridge is made of an elastic bent 'sheet of met-al, and is so ar- Y ranged as to spring againstvthe edges of the plates Gr with sufiicient forceto cause a considerable amount of friction thereon, Sothat the said bridge will not move along the plates except by the application of a considerable force.
y `This bridge has a screw-thrcaded rod, E', projecting from it along the plates G, and so that the top of e the slide-restl will slide under it.
This rod is provided with a pair of jam-nuts, 1l",
against which the edge of the top of the slide-'rest will strike when moving toward the bridge I.
G` is a scale on the top of the slide-rest,- by which thesaid bridge may be ganged' in its movement the distance required for thepitch ofteeth of the saw in hand.
XVheu onetooth has been filed and it is required to n'iove the file alongto the next one to be filed, or the notch between two, "teeth, the operator placing his foot in the strap attached to the slide-restby the hooks N, as before described, presses down thereon, so that the rest will not slide; he then raises the bridge along, the movement ot' which he observes 4by the scale G and the end of the screw E', and regulates accordingly.
When the bridge has been moved far enough hereleases the pressure on the rest H and moves the latter back until it strikes the jam-nuts, which have been previously set, so as to let it move back as far as the bridge has moved. lVhen moved back against the jam-nuts, and the file let d own on the saw, the pressure of the foot is again put on the rest, and it is held thereby against being moved by the act'of filing, or by the action of the teeth on thetile.
By this arrangement the teeth will all' have the same pitch, the depth of the notchesA between being governed by the temper-screw Q, which comes down to the top ot' the teeth not iled when the tile ha worked down far enough.
When one-half theteeth have been filed on one-augie, the file-stock lnay be shifted to the corresponding angle for the other teeth, and the bridge and thc sliderest maybe moved back to the place ofbeginning, and the other teeth tiled in the same way, or the clampingbars orthe saw may be turned, and the bridge and slide-rest correspondingly shifted on the clamping-bars to te the other halt' of the teeth without shifting the j file-holder or stock.
In conjunction with the clamping-bars, and the guideplates G thereon, I propose to employa settingapparatus, consisting of the lever a., the block or rest L, the adj usting-block K, and the adj usting-screw b, the same to be arranged for placing on the said guide plates, as shown in fig. 5, to he moved along rst on one side and then on the other to the alternate teeth, for bending them between thc pointd ofthe lever and the shoulder c of the block or rest, by pressing the lever a down, the said levervbeing lhinged to the block, and the latter overhanging the edge off the plate G opposite the lever, and receiving it inthe groove in the block K, in a manner to hold the levei', so that the force ofthe pressure will be imparted to the teeth. This block K is introduced in the overhanging part of the block to be raised or lowered by a screw, b, for varying the set, which is eccted by raising the outer edge of the block thereby.
This setting apparatus is shifted from side to side of the clamping-barsv for setting t-he teeth in the opposite direct-ions.
i', is an adjustable spring-gauge attached to the block L, and arranged to spring over the top of the teeth, and to set the block in the right plate by bearing at the end von the teeth, as shown.
Having thus described my invention,
\Ve.claim as new and desire to secure by Letters Patentl. Theedge-beveled guideplatesGG,.placed on top of and combined with the jaws A A in a saw-filing machine, as and for the purpose described.
2. The slidc-restH,workingloosely on guide-plates G, and having yokes M M combined with treadlehooks N, as and for the purpose described.
3. The plate V L, perforated at several points, and the movable lug L', combined as described, with the centers and handles, to'adapt the deviec'to a greater or lesser length of file.
4. r] .hc combination, with the above, of the bridge I, pawl A', screw E', and jamnuts F', all substantially as specified.
5. The combination, with the holder O, of the adjustable bearings R and clamping-screws S, substantially as specified.
6. The combination, with the clampiug-bars A and gauge-plates G, ot' the slide-block or rests L" K, and the lever a, all arranged substantially as specified.
i 7. The combination, with the block L", of the spring 1'., substantially as specified.
