WORK-STAN D.

SPECIFICATION forming part of Letters Patent No. 434,237, dated August 12, 1890.

Application filed February 13, 1890- Serial No. 340,287. (No model.)

To all whom it may concern.-

tain new and useful Improvements in Work-.

Stands; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to work-stands, being especially designed for the use of cofiin-trim mers; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a side elevation of my device, partly in section Fig. 2, an end elevation, and Fig. 3 a transverse section, of a telescopic brace that forms part of said device.

Referring by letter to the drawings, A A represent two standards, each of which hasa hollow central portion 1), for the reception of the lower end of a post B, this end of the post being provided with arack G, for engagement with a spring-dog D, that has its bearings in a sh ell c, fitted in the adjacent standard. The shell 0 forms part of a plate E, having bearings d for a lever F, and this lever connects with the spring-dog to facilitate the withdrawal of, the latter from engagement with the rack. By the construction just described it will be seen that each post B can be adjusted to various elevations; but in order to limit the vertical adjustment of said post in either direction I prefer to provide it with a groove e, for engagement with a stop pin or screw f, that extends in from the adjacent standard, and which further serves to prevent any accidental rotary movement of said post and consequent disarrangement of parts.

Pivotally connected to the upper end of each post Bis atransverse arm G, and secured to the under side of this arm are the ends of a segmental rod II, the latter being arranged to work in an opening in said post. In order to hold the arm G at any angle to which it may be adjusted, I provide the post B with a bearing g, and in this bearingIarrange a setscrew I, that presses against the segmental rod H, as is best illustrated in Fig. 1. Each arm G is provided with a track J for sliding clamps K K, that oppose each other and are preferably faced with blocks 72. of rubber or other suitable material. Pivotally connected to each clamp is a cam-lever L, that is brought into frictional contact with the track J, to lock said clamp in the position to which it may be adjusted on said track. Extending in from the inner side of each standard A is a bar M, and these bars are tongued and grooved to each other to form alongit-udinallyadjustable brace for the standards. In order to lock the bars together when an adjustment has been efiected, I provide one of them with a set-screw N, arranged to press against the other, and this set-screw being run down there is a binding action of the tongues on the first bar in the grooves of the second. The standards A are preferably hinged to the arms M, that constitute the longitudinally-adj ustable brace, and thus the entire device may be readily folded up to occupy but very little space when not in use.

To prevent collapse of the device when not in use, I provide the hinged standards A with hooks P, for engagement with eyes Q on the under side of the bars M, this arrangement of parts being illustrated in Fig. 1.

A coffin of any width may be clamped on the arms G and the latter adjusted to stand at such angles as the trimmer may require in order to work to the best advantage, while at the same time the posts B being vertically adjustable, the coffin may be raised or lowered at either or both ends, at the convenience of said trimmer.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, vis o 1. A work-stand provided with verticallyadjustable posts having transverse arms, clamps laterally adjustable on the arms, and cam-levers pivoted to the clamps'in opposition to said arms, substantially as set forth.

2. A work-stand provided with pivotallyadjustable transverse arms, clamps laterally adjustable on the arms, and cam-levers pivoted to the clamps in opposition to said arms, substantially as set forth.

3. A work-stand provided with verticallyadjustable posts, transverse arms pivotally adjustable on the posts, clamps laterally adj ustable on the arms, and cam-levers pivoted able on the posts, clamps laterally adj ustablo on the arms, and cam-levers pivoted to the clamps in opposition to said arms, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Fort Atkinson,

in the county of Jefferson and State of Wis- 20 consin, in the presence of two witnesses.
