Patent pending is a warning that a patent application has been filed. It is completely worthless until and unless a patent is actually issued for that invention. Patent number notice means a patent with that number was issued for the invention that is implemented in the product labeled with that number.

If it is a U.S. patent, you can go to the USPTO website for patent searches and enter the number in "patent number search". You can obtain the online image of nearly any US patent ever issued (using TIFF format). If you do not know the patent number, you may have to go elsewhere for more information, as the USPTO database prior to 1976 cannot be searched by anything other than the patent number. http://www.uspto.gov/patft/index.html
US patent 161738 is the snappily named Improvement in Hanging Carriage-Bodies, issued in 1875 to Samuel N. Beecher of Milford, CT.
A patent number will not identify the object but only some feature that was new and different enough for a company to get exclusive rights to use it after obtaining a patent. Patent numbers are issued chronologically and you can easily determine the EARLIEST year something could have been manufactured using that patent number. The uspto.gov website has lists and databases to help with that, or similar lists for patents issued in other countries. A patented invention may have been used on several models by that company and it could have sold the right to use this feature to other companies, so the same number could be on hundreds of thousands of items manufactured after the patent was issued. Many companies are still using patents issued in the 1890's on items made today. Of all the things marked on an item, the patent number is probably the least useful to identify the model or manufacturer. Now, if it were a SERIAL number and you can tell us what manufacturer's name and model number are on the item, someone may be able to give you a year of manufacture.
